Background

This study aimed to evaluate the sensory acceptability of four sweet potato cultivars (Beauregard, Morada-INTA, Colorado-INTA, and Arapey), considering two cooking methods: boiled and baked; and two cities, 9 de Julio (9DJ) and San Pedro (SP), of Buenos Aires province. 120 women were recruited in each city. A home use test was carried out. Each consumer received at home each sample in a bag containing three sweet potatoes and the evaluation form. The sensory acceptability of different characteristics of the samples was evaluated, before and after cooking. To inquire the reasons for consumption of each sample, the methodology check all that apply (CATA) was used.

Results

Of the two factors evaluated (city and cooking method), city had a significant influence when evaluating the samples. Participants of SP gave higher acceptability to Beauregard cultivar than 9DJ in most attributes. Colorado INTA had greater acceptability in some descriptors by the consumers of 9DJ. While Arapey and Morada INTA had the greatest acceptability in 9DJ trial. In CATA results 9DJ consumers associated the Beauregard cultivar with negative phrases: It tastes weird and It has little flavor/tasteless and to a lesser extent to The internal color is artificial and It breaks when cooking. While SP consumers characterized with negative phrases the Arapey and Morada INTA samples as follows: It changes color (brown) quickly, Its shape is not regular and When cooked, it has threads or fibers.

Conclusion

Consumer preferences provide opportunities for the development or improvement of new cultivars. It would be interesting to extend this study to other regions and/or countries.

背景 本研究旨在评估布宜诺斯艾利斯省 9 de Julio (9DJ) 和圣佩德罗 (SP) 这两个城市的四个甘薯品种(Beauregard、Morada-INTA、Colorado-INTA 和 Arapey)的感官可接受性,同时考虑到两种烹饪方法:煮和烤。每个城市都招募了 120 名妇女。进行了家庭使用测试。每位消费者在家中都会收到一个装有三个红薯的袋子和评估表。在烹饪前和烹饪后,对样品不同特性的感官可接受性进行了评估。在调查每个样品的消费原因时,采用了 "检查所有适用的因素"(CATA)的方法。 结果 在评估的两个因素(城市和烹饪方法)中,城市对样品的评价有显著影响。在大多数属性方面,SP 的参与者对 Beauregard 栽培品种的接受度高于 9DJ。9DJ 的消费者对科罗拉多 INTA 在某些描述指标上的接受度更高。而 Arapey 和 Morada INTA 在 9DJ 试验中的接受度最高。在 CATA 的结果中,9DJ 的消费者将 Beauregard 栽培品种与负面词语联系在一起:味道怪怪的、没什么味道/无味,其次是内部颜色是人造的、烹饪时会碎裂。SP 消费者对 Arapey 和 Morada INTA 样品的负面描述如下变色(棕色)快,形状不规则,煮熟后有线头或纤维。 结论 消费者的喜好为开发或改良新品种提供了机会。将这项研究推广到其他地区和/或国家会很有意义。

Background

At present, rice wine has the characteristics of fast fermentation, energy saving, and simple production due to the addition of commercial Saccharomyces cerevisiae. However, this kind of fermented rice wine has the disadvantages of single flavor and weak taste. To address this concern, the combination of Saccharomyces cerevisiae and non-Saccharomyces yeast has been identified as an effective approach to enhance the quality of fermented rice wine. This research aims to further enhance the ethyl ester and higher alcohol components of rice wine by utilizing the co-fermentation method of high-yield ester Zygosaccharomyces rouxii and Saccharomyces cerevisiae, thereby increasing the aroma complexity of rice wine.

Results

According to the fermentation performance and gas chromatography–mass spectrometry (GC–MS) analysis, it was found that S. cerevisiae GJM and Z. rouxii SC01 have a strong metabolic ability for glucose and sucrose. Furthermore, the crucial alcohols such as isobutanol, isoamyl alcohol, and phenylethyl alcohol increased by 85%, 29%, and 138%, respectively, when compared to single S. cerevisiae GJM. Additionally, the ethyl acetate and phenylethylene acetate were increased by 1.35 and 1.45 times, respectively, when compared to single S. cerevisiae GJM. These findings were comparable with the results of sensory evaluation and electronic nose analysis, where the fruit flavor score and the content of mellow substances were found to be higher.

Conclusion

These findings suggest that the co-fermentation of S. cerevisiae and high-yield ester Z. rouxii has the potential to enhance the quality and diversity of aroma in liquid rice wine.

背景 目前,由于添加了商品酿酒酵母,米酒具有发酵快、节能、生产简单等特点。然而,这种发酵米酒存在风味单一、口感较弱的缺点。针对这一问题,酵母菌与非酵母菌的结合被认为是提高发酵米酒质量的有效方法。本研究旨在利用高产酯酵母胭脂虫和酿酒酵母共同发酵的方法,进一步提高米酒的乙酯和高级酒精成分,从而增加米酒香气的复杂性。 结果 根据发酵性能和气相色谱-质谱(GC-MS)分析,发现酿酒酵母 GJM 和酿酒酵母 SC01 对葡萄糖和蔗糖有很强的代谢能力。此外,与单一的 S. cerevisiae GJM 相比,异丁醇、异戊醇和苯乙醇等重要醇类分别增加了 85%、29% 和 138%。此外,乙酸乙酯和乙酸苯乙酯分别比单一酿酒葡萄孢 GJM 增加了 1.35 倍和 1.45 倍。这些结果与感官评价和电子鼻分析的结果相当,后者发现水果风味评分和醇香物质含量更高。 结论 这些研究结果表明,S. cerevisiae 和高产酯 Z. rouxii 共同发酵具有提高液态米酒质量和香味多样性的潜力。

Background

The sensory, nutritional, and organoleptic characterization of strawberry genotypes is a useful strategy to guide breeding efforts on filling consumer's expectations. This work was focused on evaluating the fruit quality of six strawberry genotypes. We aimed to highlight key clues for breeders regarding the relative contribution of different techniques for fruit characterization and consumer perception, with a special focus on contrasting harvest moments.

Results

Results showed that coloration resulted less variable compared with free sugars, firmness, or volatile compounds. There was an absence of correlation between external/internal color and anthocyanin content or between soluble solids and individual sugars (glucose, fructose, sucrose). Oxygen radical absorbance capacity and 1,1-diphenyl-2-picrylhydrazyl methods showed to be complementary for antioxidant capacity determination. The predominance of esters and terpenes seems to contribute to typical strawberry flavor while a fine balance between aldehydes, terpenes, lactones, and esters found in similar proportions contributes to typical smell perception.

Conclusions

There is an important variability in fruit quality harvested fully ripe in different dates from the same harvest season and genotypes showed contrasting behaviors. Fruit color resulted more stable than other quality variables such as sugars or firmness while volatile profile showed significant changes. From a breeding perspective, it is crucial to consider many harvest moments throughout the reproductive cycle to assure a more representative fruit quality evaluation. Genotypes showing greater stability between harvests would be interesting for assuring a reproducible product during the season.

草莓基因型的感官、营养和感官特征是指导育种工作以满足消费者期望的有用策略。对6个草莓基因型的果实品质进行了评价。我们的目的是为育种者强调不同技术对水果特性和消费者感知的相对贡献的关键线索,特别关注收获时刻的对比。结果结果表明,与游离糖、硬度或挥发性化合物相比,着色剂的变化较小。外部/内部颜色与花青素含量之间或可溶性固形物与单个糖(葡萄糖、果糖、蔗糖)之间没有相关性。氧自由基吸收能力法和1,1-二苯基-2-苦味酰肼法是测定抗氧化能力的互补方法。酯类和萜烯的优势似乎有助于形成典型的草莓风味,而醛类、萜烯类、内酯类和酯类之间的良好平衡则有助于形成典型的嗅觉。结论同一收获期不同收获期全熟果实品质存在显著差异,基因型表现出不同的性状。结果表明,果色比糖和硬度等其他品质变量更稳定,而挥发性变化显著。从育种的角度来看,在整个繁殖周期中考虑许多收获时刻以确保更具代表性的果实质量评估是至关重要的。在收获之间表现出更大稳定性的基因型对于确保在季节内可繁殖的产品将是有趣的。

Background

This study evaluated the effect of spray-dried blood plasma (SDP) as a feed additive for the replacement of antibiotics in swine production. The treatments were used as strategic pulses of either antibiotics or SDP in the feed of swine during the growth and termination phases. The experimental design was conducted by 4 dietary treatments with a total of 1456 swine selected just after leaving the nursery and evaluated for 122 days until slaughter.

Results

The feed with the addition of the standard medication protocol (antibiotics) and without the inclusion of SDP had the highest feed intake (289.73 ± 3.04 kg) and reached a feed conversion of 2.57 ± 0.02 kg feed consumed per kg weight gained. Weight gain during the period of 0–122 days for the treatment with three pulses of SDP with (114.12 ± 0.64 kg) and without antibiotics (114.26 ± 1.01 kg) was higher than the control treatment (111.46 ± 1.10 kg, without antibiotics and SDP). Furthermore, the antibiotic-based treatment associated with SDP showed a 7.76% increase in weight gain when compared with the control group. Furthermore, there was a nonsignificant difference in the mortality of animals and in the index for pneumonia and ulcer score.

Conclusion

The application of SDP as a feed additive in swine at the growth and termination phases, combined with antibiotics, favored feed intake and weight gain and could be a promising alternative to upgrade zootechnical parameters in swine production.

本研究评价了喷雾干燥血浆(SDP)作为饲料添加剂在猪生产中替代抗生素的效果。在生长期和终止期,在猪饲料中作为抗生素或SDP的战略脉冲处理。试验设计采用4个饲粮处理,选取刚出苗圃的1456头猪,进行122 d的评价,直至屠宰。结果添加标准用药方案(抗生素)和不添加SDP的饲料采食量最高(289.73±3.04 kg),饲料转化率为每千克增重消耗饲料2.57±0.02 kg。3次脉冲SDP治疗组0 ~ 122 d的增重(114.12±0.64 kg)高于对照组(111.46±1.10 kg,不加抗生素和SDP)。此外,与对照组相比,与SDP相关的抗生素治疗显示体重增加7.76%。此外,在动物死亡率和肺炎指数和溃疡评分方面也没有显著差异。结论SDP作为生长期和终止期猪的饲料添加剂,与抗生素联合使用,有利于猪的采食量和增重,是提高猪生产动物技术参数的一种有前景的选择。

Abstract BACKGROUND Due to the environmental degradation caused by shrimp farming in Brazilian mangrove ecosystems, it is of great importance to developing techniques capable of inserting waste into the production chain, strengthening the premise of sustainable shrimp farming development due to its economic and social impact. In this work, solid residues from shrimp farming were used as a slow‐release fertilizer in formulations that also contain chitosan, montmorillonite, and urea. RESULTS Fertilizer granules produced without (FERT A) and with additional layers (FERT B) were characterized by elemental analysis (CHN), obtaining values of 14.4‐18.4% for carbon, 5.6‐6.9% for hydrogen, and 12.3‐19.3% for nitrogen. The fertilizers had low C/N ratios of around 1.0‐1.50, compared to a value of 0.87 for urea, the nitrogen fertilizer most widely used in Brazilian agriculture. Release tests in water showed the same release pattern in the first 5 min for FERT A and FERT B, with <10% urea release. After 30 min, the release from the fertilizers progressively increased, reaching >60% after one day and a maximum of 95‐97% after 15 days. In the first three days of incubation in the soil, the releases of nitrogen from FERT A, FERT B, and conventional urea presented different patterns, with values of 32, 10, and 90%, respectively. After incubation for 25 days, FERT A and FERT B presented nitrogen releases lower than 78%, confirming the slow release of the nutrient from these fertilizers. Degradation experiments showed that the fertilizers were biodegradable in the soil, with degradation exceeding 60% after 30 days, indicating that they could be applied to the soil without leaving residues. CONCLUSIONS The Fertilizer granules produced are slow‐release fertilizers that have the potential to increase the efficiency of nitrogen fertilization, reducing the frequency of applications and minimizing nitrogen losses in the soil. In addition, they enable the reuse of shrimp farming waste, producing a new material of agricultural interest. This article is protected by copyright. All rights reserved.
由于巴西红树林生态系统中虾类养殖造成的环境退化,由于其经济和社会影响,开发能够将废物插入生产链的技术,加强虾类养殖可持续发展的前提具有重要意义。在这项工作中,虾养殖的固体残留物被用作含有壳聚糖、蒙脱土和尿素的配方中的缓释肥料。结果通过元素分析(CHN)对不含(FERT A)和添加(FERT B)的肥料颗粒进行了表征,得到碳含量为14.4‐18.4%,氢含量为5.6‐6.9%,氮含量为12.3‐19.3%。这些肥料的碳氮比较低,约为1.0 ~ 1.50,而巴西农业中最广泛使用的氮肥尿素的碳氮比为0.87。在水中的释放试验显示,FERT A和FERT B在前5分钟的释放模式相同,尿素释放量为10%。30分钟后,肥料的释放量逐渐增加,一天后达到60%,15天后达到最大值95 - 97%。在土壤培养的前3 d, FERT A、FERT B和常规尿素的氮释放量呈现不同的规律,分别为32%、10%和90%。孵育25 d后,FERT A和FERT B的氮素释放量均低于78%,说明这两种肥料的养分释放速度较慢。降解实验表明,该肥料在土壤中可生物降解,30天后降解率超过60%,说明施用于土壤不留下残留物。结论所制肥料颗粒为缓释肥料,具有提高氮肥施用效率、减少施用频率和减少土壤氮素流失的潜力。此外,它们还可以重新利用虾类养殖废物,产生一种具有农业价值的新材料。这篇文章受版权保护。版权所有。

Background

Corn seed is produced on a large scale, and as production is carried out seasonally, the storage is needed to supply uninterrupted demand. To carry out the storage, as the material from the harvest has a high initial moisture content, it is necessary to carry out the drying process. In order to reduce energy consumption, an alternative is intermittent drying. The purpose of this article is to fit the mathematical model of intermittent drying by distributed parameters, based on experimental data of temperature and moisture content of corn seeds submitted to intermittent drying, to determine the diffusivity value and to assess heat consumption.

Results

For samples dried to the final moisture content of 16.0% on dry basis (d.b.), the condition of intermittent drying at a temperature of 40°C and 10 min of tempering period led to the lowest heat consumption, in comparison to conventional drying and to intermittent drying under higher temperatures. In addition, to obtain a final moisture content of 14.0% (d.b.), the conventional drying condition at 55°C resulted in the lowest heat consumption, compared to the other drying conditions. The distributed parameter model can predict the experimental data with a global deviation lower than 10.0%.

Conclusion

Analyzing the moisture distribution profiles for the corn seeds, it was verified that there was a difference in the moisture content along the position inside the material, being necessary to evaluate the influence of moisture distribution along the position inside the material in kinetic drying models.

玉米种子是大规模生产的,由于生产是季节性的,因此需要储存以满足不间断的需求。为了进行储存,由于收获的物料具有很高的初始水分含量,因此有必要进行干燥过程。为了减少能源消耗,一种替代方法是间歇干燥。本文的目的是通过分布参数拟合间歇干燥的数学模型,根据玉米种子进行间歇干燥的温度和水分含量的实验数据,确定扩散系数值,评估热耗。结果在干燥基础上干燥至最终含水率为16.0% (d.b.)的样品,与常规干燥和高温间歇干燥相比,在40℃间歇干燥和10 min回火条件下的热耗最低。此外,为了获得14.0% (d.b.)的最终水分含量,与其他干燥条件相比,55°C的常规干燥条件产生的热量消耗最低。分布参数模型对实验数据的预测总体偏差小于10.0%。通过对玉米种子水分分布曲线的分析,验证了玉米种子在物料内部沿位置的水分含量存在差异,这是动态干燥模型中评价物料内部沿位置水分分布影响的必要条件。

Backround

The antioxidant capacity of red beetroot has an important role in promoting human health and preventing degenerative diseases and cancer. Beetroot and colorful root vegetables are rich in phenol compounds with antioxidant properties.

Results

In this study, changes in total phenolic and flavonoid amounts and antioxidant activities and phenolic constituents of red beets heated in oven, microwave (MW), and infrared (IR) systems were investigated. The total phenolic and flavonoid contents of the red beetroots heated in oven, MW, and IR were determined between 327.85 (IR) and 619.27 mg GAE/100 g (oven) to 674.03 (IR) and 1089.24 mg/100 g (MW), respectively. Also, the antioxidant activity values of dehydrated red beet samples varied between 0.02 (IR) and 4.73 mmol/kg (Oven). The values of total phenolic, total flavonoid values, and antioxidant activities of the red beet samples were most affected by infrared. Gallic acid and 3,4-dihydroxybenzoic acid amounts of red beet samples were identified between 47.54 (Oven) and 438.65 mg/100 g (MW) to 15.98 (IR) and 45.44 mg/100 g (MW), respectively. Also, the highest p-coumaric acid (8.50 mg/100 g), ferulic acid (6.26 mg/100 g), resveratrol (2.55 mg/100 g), quercetin (4.69 mg/1000 g), cinnamic acid (0.21 mg/100 g), and kaempferol (0.64 mg/100 g) were established in red beets dehydrated in MW system.

Conclusion

When the red beet is desired to be rich in total phenolic and total flavonoid components, conventional and microwave oven cooking should be preferred, respectively. The phenolic components of the red beets dehydrated in the microwave were found to be high (except caffeic acid) compared with oven and IR.

红甜菜根的抗氧化能力在促进人体健康、预防退行性疾病和癌症方面具有重要作用。甜菜根和五颜六色的根茎类蔬菜富含具有抗氧化特性的酚化合物。结果研究了红甜菜经烤箱、微波和红外加热后总酚和类黄酮含量、抗氧化活性和酚类成分的变化。红甜菜根的总酚和类黄酮含量分别为327.85 (IR)和619.27 mg GAE/100 g (IR)至674.03 (IR)和1089.24 mg/100 g (MW)。脱水红甜菜样品的抗氧化活性值在0.02 (IR) ~ 4.73 mmol/kg (Oven)之间变化。红外对红甜菜样品的总酚值、总黄酮值和抗氧化活性影响最大。红甜菜样品中没食子酸和3,4-二羟基苯甲酸的含量分别为47.54 (Oven)和438.65 mg/100 g (MW)至15.98 (IR)和45.44 mg/100 g (MW)。在MW体系脱水的红甜菜中,对香豆酸(8.50 mg/100 g)、阿魏酸(6.26 mg/100 g)、白藜芦醇(2.55 mg/100 g)、槲皮素(4.69 mg/100 g)、肉桂酸(0.21 mg/100 g)和山奈酚(0.64 mg/100 g)含量最高。结论要使红甜菜富含总酚和总黄酮成分,应分别采用常规蒸煮法和微波蒸煮法。发现微波脱水的红甜菜的酚类成分(咖啡酸除外)比烘箱和红外高。

Background

Pasta is prepared from high-gluten wheat flour but poses great harm to gluten-intolerant population or celiac disease patients. Pearl millet flour is the cheapest among gluten-free flours and has a high nutritive index. Amaranth is a promising source of protein and fiber and is gluten-free in nature. Several studies have been done for the development of gluten-free pasta using different flour blends but an optimized formulation with high nutritive value and consumer satisfaction has not yet been identified.

Results

In this study, different blends of pearl millet and amaranth flour were used in ratios of 90:10, 80:20, 70:30, 60:40, and 50:50 for pasta preparation and their analysis based on farinographic parameters, cooking quality, and sensory scores was done. Statistical analysis by analysis of variance followed by Duncan's Multiple Range Test was performed to evaluate the optimized formulation. 60:40 blend ratio for pearl millet and amaranth flour displayed comparable farinographic properties and cooking yield to wheat-based pasta with optimized cooking loss and an overall sensory score of 8.65. Scanning electron microscopy analysis of flours and the cooked and uncooked pasta samples was also performed. Further, a multilayer perceptron neural network was developed to predict the overall quality and grade of pasta. The developed neural network gave high classification accuracy of 90.9% and 100% for training and testing sets, respectively, and can be utilized for pasta quality prediction.

Conclusion

This study provides optimized pearl millet and amaranth flour blend formulation to prepare gluten-free delicious pasta for celiac disease patients.

面食是由高筋小麦粉制成的,但对麸质不耐人群和乳糜泻患者危害很大。珍珠小米粉是无麸质面粉中最便宜的,营养指数高。苋菜是一种很有前途的蛋白质和纤维来源,在自然界中不含麸质。已经进行了几项研究,以开发使用不同面粉混合物的无麸质面食,但尚未确定具有高营养价值和消费者满意度的优化配方。结果以珍珠粟粉和苋菜粉为原料,分别以90:10、80:20、70:30、60:40和50:50的比例配制意大利面食,并对其面相参数、烹饪质量和感官评分进行了分析。采用方差分析和邓肯多元极差检验对优化后的配方进行统计分析。珍珠粟和苋菜粉的混合比例为60:40,其淀粉学特性和蒸煮产量与小麦面食相当,蒸煮损失优化,整体感官得分为8.65。对面粉、煮熟和未煮熟的面食样品也进行了扫描电子显微镜分析。进一步,开发了多层感知器神经网络来预测面食的整体质量和等级。所开发的神经网络对训练集和测试集的分类准确率分别达到90.9%和100%,可用于面食质量预测。结论本研究为乳糜泻患者制备无麸质美味面食提供了优化的珍珠粟与苋菜粉混合配方。

Background

Natural cork stoppers are commonly considered the main source of 2,4,6-trichloroanisole (TCA) in wine. However, little is known about how TCA is spread inside naturally contaminated cork stoppers. In the present work, the TCA distribution of 37 contaminated stoppers was assessed by slicing them into 3 mm discs and performing TCA analysis on each piece. Additionally, the distribution of TCA in artificially contaminated stoppers was investigated, after exposing clean stoppers to a controlled contaminated environment for 48 h.

Results

The results showed that TCA was concentrated either in small sections or distributed along the length of the stoppers. Regarding the artificially contaminated, it was found that TCA was present not only in the outer layer along the stopper length but some was found 6 mm below the surface.

Conclusion

In this study, no specific distribution pattern could represent TCA contamination in cork stoppers. An equal number of stoppers exhibited either a concentrated distribution or spread over the whole stopper. Lenticular channels are proposed to play a role in the dissemination of TCA from the surface to the interior of the stopper, as TCA was detected in the interior of the stopper within 2 h of exposure to an environment contaminated with TCA. However, the orientation of these channels does not contribute to the transportation of TCA to wine as they are perpendicular to the stopper's axis.

天然软木塞通常被认为是葡萄酒中2,4,6-三氯苯醚(TCA)的主要来源。然而,人们对TCA是如何在自然污染的软木塞内传播的知之甚少。在本工作中,通过将37个受污染的塞切成3毫米的圆盘并对每个片进行TCA分析,评估了TCA的分布。此外,将清洁瓶塞置于受控污染环境中48小时后,研究了人工污染瓶塞中TCA的分布。结果TCA主要集中在小范围内或沿塞体长度分布。对于人工污染,发现TCA不仅沿塞子长度存在于外层,而且在表面以下6mm处也存在。结论在本研究中,TCA在软木塞中的污染没有特定的分布模式。相同数量的瓶塞要么集中分布,要么遍布整个瓶塞。透镜状通道被认为在TCA从瓶塞表面传播到瓶塞内部的过程中发挥了作用,因为在暴露于被TCA污染的环境2小时内,在瓶塞内部检测到TCA。然而,这些通道的方向并不有助于TCA到葡萄酒的运输,因为它们垂直于塞子的轴。

Background

The palm tribe Phytelepheae (vegetable ivory palms) produces oleaginous fruits traditionally consumed by indigenous and local communities. We therefore analyzed the oil content as well as fatty acid (FA), carotenoid, and tocochromanol composition of fruits collected from 35 palm trees in their natural habitats, namely Phytelephas aequatorialis (Pa, n = 28), Aphandra natalia (An, n = 5), and Ammandra decasperma (Ad, n = 2).

Results

Average mesocarp oil content was high in Pa and An (ca. 30% dry mass [DM]) but not in Ad (10% DM). However, significant differences in fruit oil content between Pa populations were observed. Further, FA composition varied significantly among species and between Pa populations. The main FAs were oleic (17%–73%), palmitic (17%–41%), linoleic (2%–32%), and stearic (3%–13%) acids. The mesocarp oil of some Pa palms contained a high amount (>20%) of linoleic acid and a low amount of saturated FA (<25%). A high variability of total tocochromanol (89, 122, and 145 mg/kg oil for Pa, An, and Ad, respectively) and total carotenoids (96, 42, and 157 mg/kg for Pa, An, and Ad, respectively) content was also found.

Conclusion

The fruits of the neglected Phytelepheae palms may represent a valuable source of lipids, including the essential FA linoleic acid and lipid-soluble vitamins, and help to diversify dietary lipid sources in Ecuadorian geographical areas where there is a high rate of saturated fat consumption.

棕榈部落Phytelepheae(蔬菜象牙棕榈)生产油质果实,传统上由土著和当地社区消费。因此,我们分析了35棵棕榈树的果实的油含量、脂肪酸(FA)、类胡萝卜素和tocochromanol组成,这些棕榈树分别是:Phytelephas aequatorialis (Pa, n = 28)、Aphandra natalia (An, n = 5)和Ammandra decasperma (Ad, n = 2)。结果Pa和An的平均中果油含量较高(约30%干质量[DM]), Ad的中果油含量较低(10%干质量[DM])。但不同种群间果实含油量差异显著。此外,FA组成在种间和种群间存在显著差异。主要脂肪酸为油酸(17% ~ 73%)、棕榈酸(17% ~ 41%)、亚油酸(2% ~ 32%)和硬脂酸(3% ~ 13%)。某些棕榈中果油中亚油酸含量高(20%),饱和脂肪酸含量低(25%)。总tocochromanol (Pa、An和Ad分别为89、122和145 mg/kg油)和总类胡萝卜素(Pa、An和Ad分别为96、42和157 mg/kg)含量也存在很大的变异性。结论被忽视的Phytelepheae棕榈树的果实可能是一种有价值的脂质来源,包括必需FA亚油酸和脂溶性维生素,有助于厄瓜多尔地理区域饱和脂肪消耗率高的膳食脂质来源多样化。

The main FAs were oleic (17%–73%), palmitic (17%–41%), linoleic (2%–32%), and stearic (3%–13%) acids. The mesocarp oil of some <i>Pa</i> palms contained a high amount (&gt;20%) of linoleic acid and a low amount of saturated FA (&lt;25%). A high variability of total tocochromanol (89, 122, and 145 mg/kg oil for <i>Pa</i>, <i>An</i>, and <i>Ad</i>, respectively) and total carotenoids (96, 42, and 157 mg/kg for <i>Pa</i>, <i>An</i>, and <i>Ad</i>, respectively) content was also found.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The fruits of the neglected Phytelepheae palms may represent a valuable source of lipids, including the essential FA linoleic acid and lipid-soluble vitamins, and help to diversify dietary lipid sources in Ecuadorian geographical areas where there is a high rate of saturated fat consumption.</p>\u0000 </section>\u0000 </div>","PeriodicalId":93795,"journal":{"name":"JSFA reports","volume":"3 11","pages":"549-560"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135804750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
