Abstract
Soy is one of the most popular plant proteins. However, lipoxygenase (LOX) and trypsin inhibitor cause the undesirable beany odor and hinder trypsin activity. While thermal processing is commonly employed, it poses a risk of damaging heat-sensitive nutrients. To investigate the effects on lipoxygenase, trypsin inhibitor, and improve nutritional quality of soy milk, soybeans were treated with atmospheric cold plasma (ACP). After plasma treatment, lipoxygenase activity decreased by 97.82 %, and trypsin inhibitor activity decreased by 66 % from 61.56 TUI/mg to 20.72 TUI/mg. Additionally, the raw soy milk made from cold plasma-pretreated soybean showed a significant increase in gallic acid, genistein and antioxidant activity, resulting in reduced lipid and protein oxidation compared to thermal processing-treated sample. In conclusion, cold plasma treatment was effective in reducing lipoxygenase and trypsin inhibitor activities while maintaining heat-sensitive nutrients, which could be used in the production of soy and other plant-based products.
期刊介绍:
Official Journal of the European Federation of Chemical Engineering:
Part C
FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering.
Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing.
The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those:
• Primarily concerned with food formulation
• That use experimental design techniques to obtain response surfaces but gain little insight from them
• That are empirical and ignore established mechanistic models, e.g., empirical drying curves
• That are primarily concerned about sensory evaluation and colour
• Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material,
• Containing only chemical analyses of biological materials.
