Food quality and safety are a great public concern; outbreaks of food-borne illnesses can lead to different health problems. Consequently, rapid and non-destructive artificial intelligence approaches are required for sensing the safety situation of foods. As a promising technology, deep learning for hyperspectral imaging (HSI) has the potential for rapid food safety and quality evaluation and control. Spectral signatures of food substances are sensitive to water content variation, the extent of hydrogen bonding, geographical origin, harvesting time and the variety of food under study. Deep learning models have shown great potential in addressing the challenge of sensitivity of spectral signatures of food substances. After discussing the basics of HSI, this review provides a detailed study of various deep-learning algorithms that have been put to use via HSI in the determination of sensory and physicochemical properties, adulteration and microbiological contamination of food products. The existing literature includes HSI for evaluating quality attributes and safety of different food categories like fruits, vegetables, cereals, milk and meat. This paper presents a practical framework for deep learning-based food quality assessment using hyperspectral imagery. We demonstrate its versatility across diverse food quality domains and provide a concise step-by-step guide for researchers. It has been predicted that deep learning for HSI can be considered a reliable alternative technique to conventional methods in realising rapid and accurate inspection, for testing food quality and safety.
食品质量和安全是公众极为关注的问题;食源性疾病的爆发会导致不同的健康问题。因此,需要快速、非破坏性的人工智能方法来感知食品的安全状况。高光谱成像(HSI)深度学习是一项前景广阔的技术,具有快速评估和控制食品安全与质量的潜力。食品物质的光谱特征对含水量变化、氢键程度、地理来源、收获时间和所研究食品的种类都很敏感。深度学习模型在应对食品物质光谱特征敏感性这一挑战方面显示出巨大潜力。在讨论了 HSI 的基本原理后,本综述详细研究了各种深度学习算法,这些算法已通过 HSI 用于确定食品的感官和理化特性、掺假和微生物污染。现有文献包括用于评估水果、蔬菜、谷物、牛奶和肉类等不同食品类别的质量属性和安全性的 HSI。本文介绍了一个基于深度学习的实用框架,利用高光谱图像进行食品质量评估。我们展示了该框架在不同食品质量领域的通用性,并为研究人员提供了简明的分步指南。据预测,用于高光谱成像的深度学习可被视为传统方法的可靠替代技术,可实现快速、准确的检测,以检验食品质量和安全。

Aflatoxins contamination of foods is a global issue that severely threatens human health. This study aimed to measure total aflatoxin (AF) (aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1), and aflatoxin G2 (AFG2)) levels in red pepper flakes samples and to evaluate the potential dietary exposure and cancer risk to aflatoxin in the southeast of Türkiye. A total of 90 red pepper flake samples were collected from local markets Gaziantep, Şanlıurfa, and Hatay provinces, Türkiye. Total AF in red pepper flakes was determined by high-performance liquid chromatography with a fluorescence detector (HPLC-FLD). Then, the margin of exposure (MOE) and cancer risk were calculated. AFB1 and total AF were detected in red pepper flake samples at 98.89% and 100%, respectively. The number of red pepper flake samples exceeded the legislation limits for AFB1 was four, and there was only one sample for total AF. It was determined that AFB1 exposure could pose a risk to public health for Turkish adults (MOE < 10,000). Although AF exposure seems to be higher due to the high consumption of red pepper flakes in some regions of Türkiye, the risk of exposure and cancer may decrease because of complying with the recommendations of the dietary guidelines. The findings provide new insights into exposure to total AF by consuming red pepper flakes.
食品中的黄曲霉毒素污染是一个严重威胁人类健康的全球性问题。本研究旨在检测土耳其东南部地区红辣椒片样品中黄曲霉毒素(AF)(黄曲霉毒素 B1 (AFB1)、黄曲霉毒素 B2 (AFB2)、黄曲霉毒素 G1 (AFG1)和黄曲霉毒素 G2 (AFG2))的总含量,并评估从膳食中摄入黄曲霉毒素的潜在风险和致癌风险。研究人员从土耳其加济安泰普省、桑勒乌尔法省和哈塔伊省的当地市场共采集了90份红辣椒片样品。采用带荧光检测器(HPLC-FLD)的高效液相色谱法测定了红辣椒片中的总砷化镓。然后,计算了暴露限值(MOE)和癌症风险。红辣椒片样品中 AFB1 和总 AF 的检出率分别为 98.89% 和 100%。AFB1 超标的红辣椒片样本有 4 个,总 AF 超标的样本只有 1 个。经判定,土耳其成年人接触 AFB1 可能会对公众健康构成风险(暴露限值 < 10,000)。尽管由于土耳其某些地区大量食用红辣椒片,因此暴露于甲胎蛋白的风险似乎较高,但由于遵守了膳食指南的建议,暴露于甲胎蛋白和癌症的风险可能会降低。这些研究结果为了解食用红辣椒片暴露于总苯并呋喃的情况提供了新的视角。

This study focused on identifying the optimal yeast strain for Dechang mulberry wine fermentation blended through a multi-stage evaluation process using five commercial yeasts. Initially, the Durham tube fermentation method and weight-based analysis were employed for initial screening. Subsequently, a secondary evaluation involving physical, chemical, and sensory assessments was conducted. The final stage assessed yeast tolerance to ethanol and sulfur dioxide (SO2), and the wine’s volatile compounds were analyzed using gas chromatography-mass spectrometry. The L13 yeast strain emerged as superior, demonstrating efficient fermentation initiation, rapid primary fermentation, and production of a desirable wine profile, including optimal sugar, acid, and alcohol levels. Notably, the L13 yeast strain showed resilience, tolerating up to 11% ethanol and 170-mg/L SO2 within 7 days, and contributed to a rich aromatic profile with 23 volatile compounds, including 13 esters. These attributes render the L13 strain particularly suitable for producing mulberry wine with robust fermentation characteristics and a complex aroma, enhancing both quality and sensory appeal of the final product.
本研究的重点是通过使用五种商业酵母进行多阶段评估,确定德昌桑椹酒混酿发酵的最佳酵母菌株。首先,采用杜伦试管发酵法和重量分析法进行初步筛选。随后,进行了二次评估,包括物理、化学和感官评估。最后阶段评估了酵母对乙醇和二氧化硫(SO2)的耐受性,并使用气相色谱-质谱法分析了葡萄酒中的挥发性化合物。结果表明,L13酵母菌株更胜一筹,它能高效启动发酵,快速进行初级发酵,并酿造出理想的葡萄酒,包括最佳的糖、酸和酒精含量。值得注意的是,L13酵母菌株表现出了顽强的生命力,能在7天内耐受高达11%的乙醇和170毫克/升的二氧化硫,并能产生23种挥发性化合物(包括13种酯类)的丰富芳香。这些特性使 L13 菌株特别适合用于生产具有强劲发酵特性和复杂香气的桑椹酒,从而提高最终产品的质量和感官吸引力。

Black ginseng is a novel variant of processed ginseng that is produced by subjecting ginseng to a series of nine steaming and drying cycles. However, the precise connection between the processing cycle and the quality of black ginseng remains uncertain, and further investigation is required to establish the association between quality markers and biological activity. In this research, high-performance liquid chromatography was employed to analyze the composition of 17 ginsenosides present in samples of black ginseng. The anti-inflammatory properties of black ginseng saponin extract were tested utilizing a zebrafish tail fin amputation model. The findings indicate that the concentrations of Rg3, Rg5, and Rk1 in black ginseng samples exhibited their highest levels following the seventh processing cycle, hence demonstrating the most effective regulatory impact on neutrophils and macrophages. This study posits that the correlation between these three ginsenoside and biological activities could potentially serve as a crucial factor in ensuring the quality control of black ginseng, thereby contributing to the advancement of quality control measures for health foods and dietary supplements that utilize black ginseng as their primary constituent.
黑人参是加工人参的一种新型变体,它是通过对人参进行一系列九次蒸煮和烘干循环而制成的。然而,加工周期与黑参质量之间的确切联系仍不确定,需要进一步研究以确定质量指标与生物活性之间的联系。本研究采用高效液相色谱法分析了黑参样品中 17 种人参皂苷的成分。利用斑马鱼尾鳍截肢模型测试了黑参皂苷提取物的抗炎特性。研究结果表明,黑人参样本中的 Rg3、Rg5 和 Rk1 在第七个加工周期后含量最高,因此对中性粒细胞和巨噬细胞的调节作用最为有效。本研究认为,这三种人参皂苷与生物活性之间的相关性有可能成为确保黑人参质量控制的关键因素,从而有助于推进以黑人参为主要成分的保健食品和膳食补充剂的质量控制措施。

Tigernut (TN) is an underutilized crop with nutritional value that has remained untapped in producing extruded products. This research aims to establish the favorable extrusion conditions that produce a TN-based nutritive extruded snack with improved physicochemical characteristics. A collet extruder was used in this comparison study to examine the effects of formulation (60% TN flour and 40% brown rice [BR] vs. 60% TN flour and 40% Japonica rice [JR]). The effects of extrusion conditions, such as die temperature (90°C, 100°C, and 110°C) and screw speed (250, 300, and 350 rpm), on the physicochemical characteristics of extrudates were studied. TN-BR extrudates produced at 110°C and 350 rpm had the following improved characteristics: protein (6.09–7.33%), ash (1.40–1.59%), crude fat (7.15–9.90%), crude fiber (2.51–3.92%), reduced hardness (2.35–3.37 N), springiness (2.30–2.64), chewiness (234.71–256.72 N), bulk density (1.17–2.57 g/cm3), expansion ratio (1.65–2.24), color (L*: 68.86–74.30), water absorption index (2.69–3.45 g/g), water solubility index (13.95–21.75%), and oil absorption capacity (23.65–25.64 g/g). Extrudates produced at lower temperatures (90°C and 100°C) and screw speed (250 and 300 rpm) exhibited lesser surface consistency than the extrudates produced at 110°C and 350 rpm. The antioxidant activity and the total phenolic content (40.91–49.63 mg gallic acid equivalent/100 g) were improved significantly. Similar improvements were observed in TN-JR extrudates; however, TN-BR extrudates had better nutritional value (higher protein: 7.33%, higher ash: 1.59%, and higher antioxidant activity). The results could help with economic success, food nutrition improvement, and food security by exploiting the underutilized TN crop for sustainable extruded snacks production.
虎耳草(Tigernut,TN)是一种营养价值未得到充分利用的作物,但在生产挤压产品方面仍未得到开发。本研究旨在确定有利的挤压条件,以生产出具有更好理化特性的基于坚果的营养挤压零食。在这项比较研究中,使用了一台夹头挤压机来检测配方(60% TN 粉和 40% 糙米 [BR] 与 60% TN 粉和 40% 粳米 [JR])的影响。研究了挤压条件,如模具温度(90°C、100°C 和 110°C)和螺杆转速(250、300 和 350 rpm)对挤压物理化特性的影响。在 110°C 和 350 rpm 下生产的 TN-BR 挤压物具有以下改进特性:蛋白质(6.09-7.33%)、灰分(1.40-1.59%)、粗脂肪(7.15-9.90%)、粗纤维(2.51-3.92%)、硬度降低(2.35-3.37 N)、回弹性(2.30-2.64)、咀嚼度(234.71-256.72 N)、体积密度(1.17-2.57 g/cm3)、膨胀率(1.65-2.24)、色泽(L*:68.86-74.30)、吸水指数(2.69-3.45 g/g)、水溶性指数(13.95-21.75%)和吸油量(23.65-25.64 g/g)。在较低温度(90°C 和 100°C)和螺杆转速(250 和 300 rpm)下生产的挤出物比在 110°C 和 350 rpm 下生产的挤出物表面稠度较低。抗氧化活性和总酚含量(40.91-49.63 毫克没食子酸当量/100 克)显著提高。TN-JR 挤压物也有类似的改善;不过,TN-BR 挤压物的营养价值更高(蛋白质含量更高:7.33%,灰分含量更高:1.59%,抗氧化活性更高)。通过利用未充分利用的 TN 作物进行可持续挤压零食生产,这些结果有助于取得经济成就、改善食物营养和食品安全。

Production of phenylalanine-reduced soymilk for phenylketonuria patients 为苯丙酮尿症患者生产苯丙氨酸还原豆浆
Pub Date : 2023-12-21 DOI: 10.15586/qas.v15i4.1396

Phenylketonuria (PKU) is a hereditary disease caused by the deficiency of phenylalanine (Phe) hydroxylase enzyme or its cofactor tetrahydrobiopterin. Treatment involves a Phe-restricted diet, although food options are limited. Soymilk, derived from soybeans, is a functional food with nutritional benefits. In this study, soymilk was produced and hydrolyzed with protease of Aspergillus oryzae and papain, and then activated carbon was used to remove Phe for PKU patients. The second-derivative spectrophotometry method was used to determine Phe content in soymilk. The results showed no significant difference in dry matter, fat, and crude fiber between soymilk and Phe-extracted soymilk with respect to the control group (P < 0.05). Soymilk’s protein content was calculated as 2.74% (w/w) and that of Phe-reduced soymilk as 1.94% (w/w). Similarly, consecutive Phe content was 40.53 mg/L and 5.09 mg/L. After hydrolization, the calculated Phe removal rate was 87.44% (w/w), and the protein content was reduced by 29.19% (w/w). The study demonstrates that Phe-reduced soymilk is suitable for PKU patients, thus reducing the need for imported products and offering new market opportunities.
苯丙酮尿症(PKU)是一种因缺乏苯丙氨酸(Phe)羟化酶或其辅助因子四氢生物蝶呤而引起的遗传性疾病。治疗方法包括限制 Phe 摄入,但可供选择的食物有限。从大豆中提取的豆浆是一种具有营养价值的功能性食品。本研究用黑曲霉蛋白酶和木瓜蛋白酶水解豆浆,然后用活性炭去除PKU患者体内的Phe。采用二次衍生分光光度法测定豆浆中的 Phe 含量。结果表明,与对照组相比,豆浆和去酚豆浆的干物质、脂肪和粗纤维没有明显差异(P < 0.05)。经计算,豆浆的蛋白质含量为 2.74%(重量比),而 Phe 还原豆浆的蛋白质含量为 1.94%(重量比)。同样,连续的 Phe 含量分别为 40.53 毫克/升和 5.09 毫克/升。水解后,计算得出的 Phe 去除率为 87.44%(重量比),蛋白质含量降低了 29.19%(重量比)。这项研究表明,Phe 还原豆浆适用于 PKU 患者,从而减少了对进口产品的需求,并提供了新的市场机遇。

Essential oils (EOs) derived from crops, especially aromatic plants, have been well-acknowledged to provide several health benefits for humans. Zebrafish as an unprecedented tool has been widely used as an excellent verte-brate model in labs owing to its many useful characteristics. Its applications for rapidly and economically screening and identifying toxicity, safety, and bioactivity of EOs may serve to meet the rising demand for nutraceuticals, food supplements, and natural cosmetics. In this study, we summarized the research progress of zebrafish models in evaluating EOs. In addition, toxicity, safety, and various bioactivities of EOs were summarized using a wide variety of readily applicable zebrafish models covering antioxidant, anti-inflammatory, angiogenesis inhibition, neuromodulation, anesthesia, anti-melanogenesis, analgesic activities, etc. In conclusion, zebrafish is a valuable animal model for evaluating the bioactivity and safety of EOs, and using such a model may contribute to speeding up the identification of novel EOs with potential health functions and quality assessment, which in turn boosts the recognition of aromatic plants as important industrial crops and encourages a healthier way of life.

China ranks third in the global production of dairy products; however, dairy products are extremely vulnerable to contamination, which leaves harmful effects on the human body. This study assesses the risk classification of hazards, and examines regional and temporal distribution patterns using sample data on dairy products produced in China from 2017 to 2021. The risk value was estimated using the entropy weight method. Both global and local spatial autocorrelations were applied. The findings indicate that the primary high and relatively high-risk substances in circulation and production are veterinary medications, additives, microorganisms, and chromium whereas the main high and relatively high-risk substances in catering are additives, microorganisms, and chromium. Unqualified dairy samples were reported from 2017 to 2021. The categorical sampling of dairy products primarily takes place in western China, and only coliform group and total bacterial counts demonstrated high–high and low–low agglomeration, respectively. The dynamic adjustment of targeted regulatory opinions and regulatory plans is proposed to provide scientific basis for the safe supervision of dairy products through the classification of risk substances and the characteristics of related time and space distribution.
中国乳制品产量位居全球第三;然而,乳制品极易受到污染,对人体造成有害影响。本研究利用2017 - 2021年中国乳制品样本数据,评估了危害的风险分类,并考察了区域和时间分布模式。采用熵权法对风险值进行估计。应用了全局和局部空间自相关。调查结果表明,流通和生产中主要的高和相对高风险物质是兽药、添加剂、微生物和铬,而餐饮中主要的高和相对高风险物质是添加剂、微生物和铬。2017年至2021年报告了不合格的乳制品样品。乳制品的分类采样主要集中在中国西部,只有大肠菌群和细菌总数分别表现出高集聚和低低集聚。提出针对性监管意见和监管计划的动态调整,通过风险物质分类和相关时空分布特征,为乳制品安全监管提供科学依据。

Identification of composition characteristics of major and trace elements in wild mitten crabs (Eriocheir sinensis) from different water systems is important for protected geographical indication as well as food quality control and safety. In this study, inductively coupled plasma-mass spectrometry was employed to measure the contents of 23 elements in the muscle samples of wild Eriocheir sinensis from three water systems (Suifenhe, Nanliujiang, and Liaohe). The results of Kruskal–Wallis one-way ANOVA test comparisons revealed that most elements were significantly different in the samples collected from three water systems (P < 0.05). Geographic origin discrimination was achieved using principal component analysis in combination with hierarchical cluster analysis (HCA) and stepwise linear discriminant analysis (S-LDA). The HCA results showed the potential of eight characteristic elements for exploratory hierarchical clustering of the samples from three water systems; however, the clustering effect was unsatisfactory. The discrimination accuracy of S-LDA model for the samples from three water systems and that in cross-validation reached 100%. The health risk assessment further revealed that the normal level consumption of wild Eriocheir sinensis did not pose an appreciable health risk to consumers.
鉴定不同水系野生中华绒螯蟹体内主要元素和微量元素的组成特征对地理标志保护和食品质量安全控制具有重要意义。本研究采用电感耦合等离子体质谱法测定了绥芬河、南流江和辽河三个水系野生中华绒螯蟹肌肉样品中23种元素的含量。Kruskal-Wallis单因素方差分析比较结果表明,三种水系采集的样品中大部分元素含量存在显著差异(P < 0.05)。利用主成分分析结合层次聚类分析(HCA)和逐步线性判别分析(S-LDA)实现了地理来源判别。HCA 结果表明,8 个特征元素具有对 3 个水系的样本进行探索性分层聚类的潜力,但聚类效果并不理想。S-LDA 模型对三个水系样本的判别准确率和交叉验证准确率均达到了 100%。健康风险评估进一步表明,正常食用野生中华鹅膏菌不会对消费者造成明显的健康风险。
