The present application belongs to the field of microbial technology, and more specifically, the present application relates to an inactivated culture of plant lactobacillus BGI-N6, its use and products containing the inactivated culture. The present application provides an inactivated culture product of probiotics, which can break through the condition limitation of application of active probiotics, effectively eliminate free radicals, inhibit collagenase and elastase, inhibit skin pathogenic bacteria, so as to achieve better effect of slowing down skin aging.

The application discloses a pueraria powder-based iodine compound and a preparation method and application thereof, and comprises the following steps: mixing pueraria powder with water to form a pueraria powder water suspension; performing hydrothermal gelatinization and respiration treatment on the pueraria powder water suspension to obtain a gelatinized and respiration pueraria powder suspension; adding potassium iodide, potassium iodate and acid into the gelatinized and respiration pueraria powder suspension, adjusting the pH value of the system to be acidic, performing reaction, and obtaining the pueraria powder-based iodine compound through post-treatment. The application constructs a loading framework through gelatinization and respiration of pueraria powder, realizes stable loading of iodine by relying on in-situ reaction, and realizes the multiple effects of low stimulation, efficient inhibition of digestive tract pathogenic bacteria and precise regulation of intestinal microecology by synergistic effect of the strong bactericidal capacity of iodine which is not prone to drug resistance and the inherent intestinal flora regulation activity of pueraria powder, so that the pain points of instability and strong irritation of traditional iodine preparations are solved, and a new way for treating digestive tract infectious diseases is opened up.
