花椒油和藤椒油加速氧化过程中风味品质变化

旨在为提高花椒油和藤椒油品质稳定性和预测其货架期提供参考，研究储存过程中花椒油和藤椒油风味品质变化。采用Schaal烘箱法探讨加速氧化过程中（0~35 d）花椒油和藤椒油的酸值、过氧化值、麻味物质及挥发性风味成分的变化。结果表明：加速氧化过程中花椒油和藤椒油的酸值（KOH）均满足国家限量标准（≤3 mg/g）,而过氧化值分别在15 d和20 d时超出国家限量标准（≤0.25 g/100 g）。花椒油和藤椒油分别加速氧化10 d和15 d时麻味物质总量损失率分别为5.86% 和10.42%，挥发性风味成分总量损失率分别为35.07%和70.01%；加速氧化结束时，花椒油和藤椒油中麻味物质总量和挥发性风味成分总量大幅减少，麻味物质总量损失率分别为37.15%和37.30%，挥发性风味成分总量损失率分别为82.03%和89.08%；对挥发性风味物质进行主成分分析(PCA)发现，未加速氧化的油与加速氧化后的油区分明显。花椒油和藤椒油在储存过程中麻味物质和香气成分存在着不同程度的损失，且长时间储存易氧化酸败，对产品风味品质影响较大。

Review of techniques to manufacture micro-hydrogel particles for the food industry and their applications

Microgels are ‘soft’ microscopic cross-linked polymeric particles that are being increasingly exploited in a variety of industries for rheology control, encapsulation and targeted delivery. They are valued because of the ability to tune their functionality to address specific applications in oil recovery, coatings, drug delivery, cosmetics, personal care and foods. Food microgels are typically biopolymer hydrogels in the form of microspheres, nanospheres (also called nanogels), spheroids and fibres. The utilisation of engineered microgels in foods has so far been limited, despite their great potential to address several needs in the food industry, including: satiety control, encapsulation of phytonutrients and prebiotics, texture control for healthier food formulations (e.g. reduced fat products), and targeting delivery to specific areas in the digestive tract. We review the scientific and patent literature on the utilisation and manufacturing methods for producing microgels with an emphasis on micro-hydrogels for food applications.     

12—A CRITIQUE OF SOME HYPOTHESES RELATING TO THE HETEROGENEITY OF THE HIGH-SULPHUR PROTEINS OF WOOL

Joubert and Burns prepared a large number of fractions from the high-sulphur proteins of wool and estimated their molecular weights and amino-acid compositions. Their data have been re-examined in order to look for statistically significant interrelations between amino acids and between the proportion of various amino acids and molecular weight. Statistical analysis of the data is also used to examine the credibility of some hypotheses concerning the mechanism of keratin biosynthesis and to provide further evidence for the existence of families of proteins within the high-sulphur fractions of wool.

Anti-mutagenic compounds from corn

In previous studies with aflatoxin-contaminated corn an uncharacteristic response for AFB₁ in the Salmonella/microsomal mutagenicity assay (Ames test) was observed and the presence of anti-aflatoxin factors in the corn was suggested. In the current study, corn was extracted and fractionated using thin layer chromatography (TLC) using different developing solvent systems and the Ames test was used to monitor for anti-mutagenic activity in the corn fractions. Both Salmonella tester strains TA98 and TA100 with metabolic activation (S9) were used. Several corn fractions, at different stages in the isolation and purification process, showed anti-mutagenic dose-responses when exposed to pure AFB₁. Corn extracts were non-toxic to the tester strains and TLC fractions that showed the best anti-mutagenic dose-responses were selected for further partial characterization analyses.
