Abstract: Chilled meat is rich in nutrients but highly susceptible to contamination by spoilage microorganisms during slaughter, processing, storage and transportation. Microbial spoilage in foods has become a major concern for food safety. Predictive models for microbial growth in foods can judge the growth or survival of major spoilage microorganisms in foods, thereby allowing the evaluation and prediction of the quality and safety of meat. The artificial neural network (ANN), a complex nonlinear model, has the advantages of massively parallel processing, distributed storage, high adaptability, and fault tolerance. This paper reviews the main spoilage microorganisms in chilled meat and the application of traditional microbial prediction models and ANN models in meat to provide ideas for constructing microbial growth prediction models in foods.
Keywords: chilled meat; spoilage microorganisms; artificial neural network; prediction model

冷鮮肉是日常膳食中不可或缺的一部分。國家統計局統計,2022年中國豬、牛、羊、禽肉產量9 227萬 t,
比上年增長3.8%;其中,豬肉產量5 541萬 t,增長4.6%;牛肉產量718萬 t,增長3.0%;羊肉產量525萬 t,增長2.0%;禽肉產量2 443萬 t,增長2.6%。冷鮮肉具有肉質嫩、味鮮美且富含人體所需的蛋白質、脂肪、碳水化合物和微量元素等特點[1],深受消費者喜愛,因此逐漸成為國際鮮肉生產和銷售的主流。但冷鮮肉食品在加工、貯藏等過程中易受到微生物的污染,是各類微生物的理想基質[2]。貯藏不當會加快微生物的生長速率,從而導致肉類變質而引發食物中毒等一系列的安全問題[3-4]。……
