Special Issue Information

Dear Colleagues,

Plant-based foods are complex materials, which contain nutrient substances as well as functional/bioactive compounds, for instance, flavones, pigments, polyphenols, polysaccharides, oligosaccharides, antioxidants, enzymes, etc. Foods can produce tons of bioactive compounds during digestion, and all these functional/bioactive compounds play critical roles in human health and even some diseases. Therefore, efficient discovery of such functional/bioactive compounds is significant, especially high-throughput discovery or screening. Because of the rapid development of information science and technology and omics (genomics, proteomics, metabolomics, flavour omics, etc.), there is increased use of high-throughput techniques and virtual prediction technology, which greatly promotes the efficient discovery and innovation of functional/bioactive compounds in foods. In addition, examinations of the health effects of these bioactive compounds in plant-based food are active areas of scientific inquiry. There are exciting prospects that some bioactive compounds will reduce the risk of many diseases, including chronic diseases, cancers, etc.

Thus, the present Special Issue will focus on research updates in the characterization and valuation of bioactive plant compounds in terms of new techniques for the screening, prediction and design of functional/bioactive compounds in plant-based foods using high-throughput methods, as well as the establishment of novel techniques in the methodologies of bioactivity in vitro or in vivo, and even the illustration of molecular mechanisms to increase our understanding of the biology of bioactive compounds. This Special Issue will provide the scientific basis for future efforts to use biotechnology to modify or fortify plant-based foods and their components as a means to improve public health.

Globally, type 2 diabetes (T2DM) is on the rise. Maintaining a healthy diet is crucial for both treating and preventing T2DM.As a common vegetable in daily diet, broccoli has antioxidant, anti-inflammatory and anticarcoma physiological activities. We developed a mouse model of type 2 diabetes and carried out a systematic investigation to clarify the function of broccoli in reducing T2DM symptoms and controlling intestinal flora. The findings demonstrated that broccoli could successfully lower fasting blood glucose (FBG), lessen insulin resistance, regulate lipid metabolism, lower the levels of TC, TG, LDL-C, and MDA, stop the expression of IL-1β and IL-6, and decrease the harm that diabetes causes to the pancreas, liver, fat, and other organs and tissues. Furthermore, broccoli altered the intestinal flora’s makeup in mice with T2DM. At the genus level, the relative abundance of Allobaculum decreased, and that of Odoribacter and Oscillospira increased; At the family level, the relative abundances of Odoribacteraceae, Rikenellaceae and S24-7 decreased, while the relative abundances of Erysipelotrichaceae and Rikenellaceae increased.

Acrylamide is present in thermally processed foods, and it possesses toxic and carcinogenic properties. L-asparaginases could effectively regulate the formation of acrylamide at the source. However, current L-asparaginases have drawbacks such as poor thermal stability, low catalytic activity, and poor substrate specificity, thereby restricting their utility in the food industry. To address this issue, this study employed consensus design to predict the crucial residues influencing the thermal stability of Corynebacterium glutamicum L-asparaginase (CgASNase). Subsequently, a combination of site-point saturating mutation and combinatorial mutation techniques was applied to generate the double-mutant enzyme L42T/S213N. Remarkably, L42T/S213N displayed significantly enhanced thermal stability without a substantial impact on its enzymatic activity. Notably, its half-life at 40 °C reached an impressive 13.29 ± 0.91 min, surpassing that of CgASNase (3.24 ± 0.23 min). Moreover, the enhanced thermal stability of L42T/S213N can be attributed to an increased positive surface charge and a more symmetrical positive potential, as revealed by three-dimensional structural simulations and structure comparison analyses. To assess the impact of L42T/S213N on acrylamide removal in biscuits, the optimal treatment conditions for acrylamide removal were determined through a combination of one-way and orthogonal tests, with an enzyme dosage of 300 IU/kg flour, an enzyme reaction temperature of 40 °C, and an enzyme reaction time of 30 min. Under these conditions, compared to the control (464.74 ± 6.68 µg/kg), the acrylamide reduction in double-mutant-enzyme-treated biscuits was 85.31%, while the reduction in wild-type-treated biscuits was 68.78%. These results suggest that L42T/S213N is a promising candidate for industrial applications of L-asparaginase. Full article
