Modulation of starch digestibility using non-thermal processing techniques:A review

Grain & Oil science and Technology 2024年第3期7卷 209-218页

作者： Liyuan Rong Weiqi Fei Zhijun Wang Xianxiang Chen Huiliang Wen Jianhua Xie Mingyue Shen State Key Laboratory of food science and Resources Nanchang University school of biosystems and food engineering University College Dublin

Obesity and type 2 diabetes are widespread throughout the world, especially in developed countries. Starch is an important part of human staple food, the modulating of starch digestibility is conducive to reducing postprandial blood glucose levels and alleviating the chronic disease caused by high caloric intake. The digestion properties of starch are correlated with its structural features, including crystallization, amylose/amylopectin ratio, non-starch components, etc. Among the modified methods applied to regulate starch digestibility, non-thermal processing techniques(NTPT) receive extensive attention due to the characteristics of safety, environmental friendliness and high efficiency. The influence and mechanism of NTPT on the digestion properties of starch are discussed in this review, including ultrasounds, high pressure, γ-irradiation, etc. NTPT induces the alternation of morphological and structural characteristics of native starch, changing their sensitivity to enzymes. The effects of NTPT on the digestibility of starch are highly related to the processing parameters and structure characteristics of native starch. The review shows that NTPT is an effective way to modulate the digestion properties of starch and prevent people from suffering from chronic diseases such as obesity and type 2 diabetes.

Proteomic mechanism of Bacillus cereus endospore against plasma-activated water(PAW)

引用

food science and Human Wellness 2024年

作者： Xiao Hu Jinsong Feng Xinyu Liao Tian Ding Ruiling Lü school of biosystems engineering and food science， zhejiang university Future food Laboratory， Innovation Center of Yangtze River Delta， zhejiang university Ningbo Innovation Center， zhejiang university

Plasma-activated water (PAW) indicated promising potential in controlling the biological contamination of Bacillus cereus， which eliminated its evolutionary endospore that improves its survival ability. However， the spore inactivation mechanism by PAW at molecular level was not well understood. The mechanism of the Bacillus cereus endospore against PAW at proteomic levels was demonstrated. The Tandem Mass Tag (TMT) labeling was performed. By comparing the treatment groups with control (including PAW and PAW added superoxide dismutase (SOD)) ， the expression of 251 proteins (with the number of 207 up- and 44 down-regulated) and 379 proteins (with the corresponding number of 238 and 141) were drastically affected， separately. The six categories based on the protein-protein interaction (PPI) networks included oxidation-reduction， transport， sporulation and DNA topological change， gene expression， metabolism， and others. The three dehydrogenases (Gene hisD， BC＿2176， and asd) in PAW while oxidoreductase (Gene BC＿0399 and BC＿2529) in SOD were activated to maintain the antioxidation of spores. The proteins (BC＿4271 and BC＿2655) in SOD were dramatically activated， which were involved in the carbohydrate， amino acid， and energy-coupling transport. All the small， acid-soluble spore proteins were activated in both groups to protect the spores’ DNA. In SOD， genes metG2 and rpmC also were considered important factors in translation while this role was played in gene groES but not rpmF in PAW. The PAW activated the biogenesis of cell wall/membrane/envelope and phosphorelay signal transduction system to contribute to the survival of spores whereas the SOD damaged these two processes as well as cell division， chromosome separation， organic acid phosphorylation， base- and nucleotide-excision repair to lead to the death of spores. This would promise to lay the foundation for advancing the study of the intrinsic mechanism of spore killing against PAW and can also provide a reference f
