There is a broad field of economic online and in-situ field analysis applications like the online monitoring of volatile components for quality monitoring in food processing. Looking to beer production, for example, the quality of the raw materials like grain, hops and yeast have to be investigated because these items could be the source of a contamination with 2,4,6-Trichloranisol (TCA). TCA is a chloric aromatic hydrocarbon with intensive mildewed and moldy smell and, therefore, leads to immense damage of the product not only limited to beer production. Another field of application is the monitoring of food transport and store chains to guarantee the quality of food and to avoid harm for the consumers. Typically, Volatile Organic Compounds (VOCs) are often evaporated, which can be measured by sophisticated gas sensor systems and therefore used for investigations of the mentioned problems. The purpose of this paper is to introduce a sophisticated sensor system which was developed to measure VOCs. The principal sensing element is a four-fold sensor array on a 4x4 mm2 alumina chip (Figure 1), which comprises four micro-dispensed thickfilm sensing layers of different SnO2/additive-composites. Operating MOG sensors thermo-cyclically and simultaneous sampling of the conductance yields gas specific Conductance-over-Time-Profile (CTP) features. Further-more, an innovative calibration and evaluation procedure ProSens will be introduced, which enables substance identification and concentration determination even in the case of varying environmental conditions from the characteristic CTP shapes. Many field analysis problems like those mentioned above are looking for innovative solutions. The above described sensor chip in combination with the numerical procedure ProSens is a powerful tool to solve existing problems in the area of food monitoring and food processing.
经济在线和现场分析应用领域广泛,如食品加工中用于质量监测的挥发性成分的在线监测。例如,在啤酒生产中,必须调查谷物、啤酒花和酵母等原材料的质量,因为这些物质可能是2,4,6-三氯苯酚(TCA)污染的来源。TCA是一种氯代芳烃,具有强烈的发霉气味,因此,不仅限于啤酒生产,还会对产品造成巨大损害。另一个应用领域是对食品运输和连锁店的监控,以保证食品质量并避免对消费者造成伤害。通常,挥发性有机化合物(VOC)经常被蒸发,这可以通过复杂的气体传感器系统进行测量,因此用于研究上述问题。本文的目的是介绍一种用于测量挥发性有机物的复杂传感器系统。主要传感元件是4x4 mm2氧化铝芯片上的四倍传感器阵列(图1),该阵列包括四个不同SnO2/添加剂复合材料的微分配厚膜传感层。MOG传感器热循环操作和电导的同时采样产生气体比电导随时间分布(CTP)特征。此外,还将引入一种创新的校准和评估程序ProSens,即使在环境条件与CTP特征形状不同的情况下,也能进行物质识别和浓度测定。许多像上面提到的现场分析问题都在寻找创新的解决方案。上述传感器芯片与数值程序ProSens相结合是解决食品监控和食品加工领域中存在的问题的有力工具。

The aroma of cooked rice is contributed mainly by the compound 2-acetyl-1-pyrroline (2-AP) and it is also found in aromatic Pandanus leaves (Pandanus amaryllifolius). Therefore, this experiment was conducted to investigate a physical mechanism of transferring 2-AP from Pandanus leaves to non-aromatic polished rice. Milled Samba rice (medium/ bold) grains were vacuum dried for 24 hours to remove moisture and develop a porous structure on the grain. Then the rice samples were mixed with Pandanus leaves and microwaved for predetermined times in sealed bags to 65°C to explode oil glands and release 2-AP. After three weeks of chemical exchange time in bags, the consumer acceptability was tested based on preference. The results revealed that the consumer acceptability of rice could be significantly increased with appropriate microwave heating time. Data has shown that the mean acceptability rank value of 3.47 with 45 minutes microwaving (about 65°C) against the rank mean of 1.4 for the control in a five-point hedonic test. However, the increase of microwaving time above the optimum level produced an unpleasant aroma in rice and decreased the acceptability. Therefore, this physical treatment could be used to increase the palatability and acceptability of non-aromatic rice.
熟米的香气主要由化合物2-乙酰基-1-吡咯啉(2-AP)贡献,在香豆叶(Pandanus amaryllifolius)中也发现了这种化合物。因此,本试验旨在探讨2-AP从香豆叶向非芳香精米转移的物理机制。碾碎的桑巴米(中等/粗大)谷物真空干燥24小时,以去除水分并在谷物上形成多孔结构。然后将大米样品与Pandanus叶子混合,在密封袋中加热至65°C,以爆炸油腺并释放2-AP。经过三周的化学物质在袋子里的交换时间,消费者的接受程度是基于偏好的测试。结果表明,适当的微波加热时间可显著提高大米的消费者接受度。数据表明,在5点享乐测试中,微波45分钟(约65°C)的平均可接受等级值为3.47,而对照组的平均可接受等级值为1.4。然而,微波时间超过最佳水平后,大米产生难闻的香气,降低了接受度。因此,这种物理处理可以提高非芳香大米的适口性和可接受性。

This study was conducted to test the effectiveness of a 33%, 50%, 66% and 100% substitution of white and brown sugar with a zero calorie sweetener (Stevia) and a bulking agent (Benefiber). As Stevia and Benefiber increased, %Δ weight, %Δ height and pH did not differ significantly between variations and control samples. Compared to control, moisture decreased significantly with all substitutions (p<0.05). Water activity decreased significantly with 66% and 100% substitutions. Area and diameter also significantly decreased with the replacement of sugar. Hunter colorimeter showed significantly increased crust lightness at 66% and 100% while the crumb lightness decreased significantly with all substitutions. Texture analysis measured using a TA.XT Plus Texture Analyzer (Texture Technologies Corp., Scarsdale, NY) indicated a significant increase in fracturability at 66% and 100% substitution. Hardness was found to significantly increase by 50%, 66% and 100% (p<0.05). Sensory evaluations indicated that substitutions at 50%, 66%, and 100% were significantly different (p<0.05) in color, texture, taste and overall acceptability compared to control. Substitutions at 33%, 50% and 66% all ranked above 3 (acceptable) in appearance, color, taste, texture and overall acceptability. The nutrient analysis showed that the 66% variation increased in fiber by 3 grams (289.09%), and decreased in sugar content by over 4 grams (-48.70%) per 27 grams serving compared to control. Improved nutritional content and acceptability make Stevia and Benefiber a viable sugar replacement at 66% substitution for oatmeal cookies.
本研究的目的是测试用零热量甜味剂(甜菊糖)和膨化剂(Benefiber)分别代替33%、50%、66%和100%的白糖和红糖的有效性。随着甜叶菊和贝尼法尔的增加,变异样品和对照样品之间的%Δ体重、%Δ身高和pH没有显著差异。与对照相比,各替代处理的水分均显著降低(p<0.05)。66%和100%替代后,水活度显著降低。随着糖的添加,面积和直径也显著减小。亨特色度计在66%和100%时显着增加了外壳亮度,而所有替代都显着降低了面包屑亮度。用TA测定织构分析。XT Plus纹理分析仪(Texture Technologies Corp., Scarsdale, NY)表明,可压裂性显著提高66%和100%。硬度分别提高50%、66%和100% (p<0.05)。感官评价表明,与对照组相比,50%、66%和100%的替代品在颜色、质地、味道和总体可接受性方面存在显著差异(p<0.05)。33%, 50%和66%的替代品在外观,颜色,味道,质地和总体可接受性方面均排名在3(可接受)以上。营养分析表明,与对照组相比,每27克的纤维含量增加了3克(289.09%),糖含量减少了4克(-48.70%)以上。改善的营养成分和可接受性使甜菊糖和贝尼法纤维成为可行的糖替代品,替代燕麦饼干66%。

Effect of pumpkin flour on the physico-chemical, rheological, nutritional and sensory characteristics on biscuits was studied by incorporating pumpkin flour at different concentrations from 5-25% based on refined wheat flour (Maida). Addition of 15% of pumpkin flour was found to be optimum for biscuit preparation. Effect of incorporation of pumpkin flour had a significant (p ≤ 0.05) effect on rheological characteristics of wheat flour studied by using mixograph, alevo-consistograph and rapid visco analyser etc. During storage, the chemical changes and overall acceptability scores were found to be negatively correlated (r<-0.97).

The development of functional foods to promote health is currently of global relevance. Prebiotics are food ingredients that exert beneficial health effects on the host by stimulating the growth of probiotics. This work examined the potential of brown rice in the production of probiotic beverage (PB) inoculated with Lactobacillus acidophilus and Streptococcus thermophillus. The beverage quality and probiotic viability were evaluated over 4 weeks storage and compared with a control beverage (CB) which was produced without inoculation. The physicochemical analyzes result showed viscosity of PB (601-1200 cp) to be higher than CB (500-550 cp). The specific gravity of PB (0.99-1.90) was not significantly different from CB (1.00-1.92). The % Brix increased more in PB (6.10-7.00) than in CB (4.90-6.50). There was more reduction in pH in a probiotic beverage (5.32-4.77) than in the control (6.21-5.96). The total microbial count at the end of fermentation ranged from 3.3 × 108 to 4.1 × 109 CFU/ml for PB and 1.0 × 101 to 3.3 × 103 CFU/ml for the control sample CB. There were no detectable fungi and coliform growths in the probiotic sample (PB). However, a range of 1.1 × 101 to 4.2 × 103 CFU/ml fungi and <1.0 × 101 CFU/ml coliforms were observed in the control (CB). Lactobacillus acidophilus (5.0 × 106 to 2.9 × 107) CFU/ml proliferated more compared to Streptococcus thermophillus (2.0 × 105 to 3.2 × 106) CFU/ml in the probiotic sample (PB) but lagged in the control sample (CB). The beverages differed significantly (p ≥ 0.05) with respect to overall sensory acceptability. The inoculated beverage (PB) showed better acceptance than the non-fermented beverage (CB). At the end of 4 weeks of evaluation, the inoculated brown rice beverage was able to support high probiotic cell viability which confirms its prebiotic potential.
开发促进健康的功能性食品目前具有全球相关性。益生元是通过刺激益生菌的生长对宿主产生有益健康作用的食品成分。本研究考察了糙米接种嗜酸乳杆菌和嗜热链球菌生产益生菌饮料的潜力。在4周的储藏时间内,评价了该饮料的品质和益生菌活力,并与未接种的对照饮料(CB)进行了比较。理化分析结果表明,PB的黏度(601 ~ 1200cp)高于CB (500 ~ 550cp)。PB比重(0.99 ~ 1.90)与CB比重(1.00 ~ 1.92)差异不显著。白锐度百分比在PB组(6.10 ~ 7.00)高于CB组(4.90 ~ 6.50)。益生菌饮料的pH值(5.32-4.77)比对照组(6.21-5.96)降低得更多。发酵结束时,PB的微生物总数为3.3 × 108 ~ 4.1 × 109 CFU/ml,对照样品CB的微生物总数为1.0 × 101 ~ 3.3 × 103 CFU/ml。益生菌样品(PB)中未检测到真菌和大肠菌群的生长。而在对照(CB)中,真菌数量在1.1 × 101 ~ 4.2 × 103 CFU/ml之间,大肠菌群数量<1.0 × 101 CFU/ml。在益生菌样品(PB)中嗜酸乳杆菌(5.0 × 106 ~ 2.9 × 107) CFU/ml的增殖高于嗜热链球菌(2.0 × 105 ~ 3.2 × 106) CFU/ml,而在对照样品(CB)中增殖滞后。两种饮料的总体感官接受度差异显著(p≥0.05)。接种后的饮料(PB)比未发酵的饮料(CB)具有更好的接受性。在4周的评价结束时,接种的糙米饮料能够支持较高的益生菌细胞活力,证实了其益生元潜力。

Prebiotics are food ingredients that exert beneficial health effects on the host by stimulating the growth of probiotics. This work examined the potential of brown rice in the production of probiotic beverage (PB) inoculated with Lactobacillus acidophilus and Streptococcus thermophillus. The beverage quality and probiotic viability were evaluated over 4 weeks storage and compared with a control beverage (CB) which was produced without inoculation. The physicochemical analyzes result showed viscosity of PB (601-1200 cp) to be higher than CB (500-550 cp). The specific gravity of PB (0.99-1.90) was not significantly different from CB (1.00-1.92). The % Brix increased more in PB (6.10-7.00) than in CB (4.90-6.50). There was more reduction in pH in a probiotic beverage (5.32-4.77) than in the control (6.21-5.96). The total microbial count at the end of fermentation ranged from 3.3 × 108 to 4.1 × 109 CFU/ml for PB and 1.0 × 101 to 3.3 × 103 CFU/ml for the control sample CB. There were no detectable fungi and coliform growths in the probiotic sample (PB). However, a range of 1.1 × 101 to 4.2 × 103 CFU/ml fungi and <1.0 × 101 CFU/ml coliforms were observed in the control (CB). Lactobacillus acidophilus (5.0 × 106 to 2.9 × 107) CFU/ml proliferated more compared to Streptococcus thermophillus (2.0 × 105 to 3.2 × 106) CFU/ml in the probiotic sample (PB) but lagged in the control sample (CB). The beverages differed significantly (p ≥ 0.05) with respect to overall sensory acceptability. The inoculated beverage (PB) showed better acceptance than the non-fermented beverage (CB). At the end of 4 weeks of evaluation, the inoculated brown rice beverage was able to support high probiotic cell viability which confirms its prebiotic potential.","PeriodicalId":90897,"journal":{"name":"Journal of food processing & technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69972483","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}

Changes in the physicochemical, thermo-rheological and antioxidant properties of the cowpea and potato starch subjected to gamma irradiation were studied. It was found that apparent amylose content, swelling index, enthalpy of gelatinization, transition temperature and total crystallinity of the starches significantly (p ≤ 0.05) decreased with an increase in irradiation dose. Similarly, significant (p ≤ 0.05) decline in the pasting properties (peak, trough, setback, final viscosity, and pasting temperature) for both the starches was observed with increasing the ionizing dose. On the contrary, the increased solubility index was incurred upon subjecting the starch to gamma irradiation. The irradiated starch granules remained intact showing no surface fissures. Antioxidant capacity, FRAP values, and DPPH% inhibition, increased as the irradiation dose increases.
研究了辐照后豇豆和马铃薯淀粉的理化、热流变和抗氧化性能的变化。结果表明,随着辐照剂量的增加,淀粉的表观直链淀粉含量、膨胀指数、糊化焓、转变温度和总结晶度显著降低(p≤0.05)。同样,随着电离剂量的增加,两种淀粉的糊化性能(峰值、低谷、挫折、最终粘度和糊化温度)均显著下降(p≤0.05)。相反,淀粉经γ射线照射后,其溶解度指数增加。辐照后的淀粉颗粒保持完整,表面无裂缝。抗氧化能力、FRAP值和DPPH%抑制随辐照剂量的增加而增加。
