The prevalence of ulcerative colitis (UC) is increasing annually， while current non-targeted drugs for UC have limited effectiveness， easily relapsed， and serious side effects. Herein， curcumin (Cur)-loaded nanoparticle with conlon-targeted property based on Mesona chinensis polysaccharides was developed for the synergistic and targeted improvement of UC. Results show that ZmNPs have good encapsulation of Cur， targeted delivery of Cur to the colon， and prolonged its retention time. In vivo safety assessments have shown that ZmNPs have good safety and biocompatibility. As expected， Cur-ZmNPs effectively alleviated the symptoms of DSS-induced UC by decreasing colonic inflammation by inhibiting the TLR4/MAPK pathway， regulating the levels of oxidative stress and immune homeostasis of UC mice. Oral administration of Cur-ZmNPs can reduce apoptosis of intestinal epithelial cells， alleviate colonic mucosal damage and repair intestinal barrier function. Cur-ZmNPs also had a positive effect on improving gut microbiota disorders and promoting the production of SCFAs. This study provides a novel strategy for synergistic alleviation of UC by MCP-based NPs loaded with food bioactives.

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.
