Abstract: Chicken Feet with Pickled Pepper is a representative product of the series of industrialized products of pickled pepper meat in Southwest China. In this paper, the traditional isolation and culture combined with 16S rDNA molecular biology method was used to identify the microorganisms that cause the bag swelling and deterioration of pickled pepper chicken feet. The results showed that Staphylococcus, Bacillus and Pseudomonas were the main causes of corruption. According to the biological characteristics of specific spoilage bacteria, this paper puts forward relevant suggestions to prolong the shelf life of pickled pepper chicken feet.

鸡爪富含胶原蛋白,营养价值较高,20世纪70年代以前主要作为禽肉制品烹饪的下脚料,1978年后,我国开始进口西方国家肥厚、型大、价廉的鸡爪,西南地区劳动人民以其食物的新鲜麻辣特色为出发点,创造性地将鸡爪与泡椒结合到一起,制作出具有鲜辣脆嫩风味的泡椒凤爪。(剩余3441字)
