The anti-counterfeiting of agricultural products plays an important role in protecting the rights and interests of consumers and maintaining the healthy development of the food market. Traditional anti-counterfeiting technology mainly relies on anti-counterfeiting features of packaging or labeling, which has the risk of being copied and reused. Biological fingerprint anti-counterfeiting is a method of anti-counterfeiting that takes the biological fingerprint of agricultural products as the anti-counterfeiting feature. This paper aims to take the distribution of lenticels on the surface of mango as a biological fingerprint, and propose a mango biological fingerprint anti-counterfeiting method. As the mango ripens, the peel color of mango will change significantly, which will affect the accuracy of anti-counterfeiting identification. In this paper, the images of ripe mangoes are classified by Fuzzy C-means clustering, and appropriate image enhancement technology is used to highlight the features. The results show that the mango biological fingerprint anti-counterfeiting method based on Fuzzy C-means clustering has good accuracy and robustness, and effectively reduces the impact of peel color change on anti-counterfeiting identification during mango ripening. These results support that it is feasible to use the lenticels distribution of mango as a biological fingerprint. In this paper, a computer vision anti-counterfeiting method based on lenticels distribution is proposed.

This research aimed to study the preventive and relieving outcomes of kiwi berry on constipation. The administration of kiwi berries to mice resulted in a significant increase in body weight gain of 148.2% compared to mice that were constipated. The number of stools and the water content of stools both increased by 138.5% and 106.5%, respectively. The gastrointestinal transit rate increased by 45.3%, and the time it took for the first dark stool to form decreased by 57.5%. The levels of the excitability neurotransmitters were found to be higher in the group that had been given kiwi berries in comparison to the group that had been given loperamide. The opposite results were produced by vasoactive intestinal peptide (VIP) and aquaporin-3 (AQP3). In addition, kiwi berry consumption may lessen epithelial cell apoptosis and promote colon health. All the results point to kiwi berries as an extremely promising food supplement for the prevention and relief of constipation in the future since they successfully prevent and alleviate constipation brought on by loperamide.
