Shelf life of foods, mainly meat and meat products, is affected by its physical and chemical properties like color, pH, water holding capacity etc. In developed countries
food losses occur at production, retail and consumer levels with meat commodities accounting for 41% of the total loss in US during 2008. These losses are because of
spoilage due to inappropriate packaging, improper storage conditions, food wastage, and lack of consumer awareness. By focusing on shelf life and quality issues at the production level, we can overcome some of the major problems faced by the food manufacturers.

Effects Of Potassium Lactate, Encapsulated Citric Acid And Storage Temperature On Microbial Growth And Shelf Life Of Pork Sticks, Yen-Kan Su

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A new product, pork sticks, was developed. Optimum shelf life and safety were major concerns associated with this product. Potassium lactate (3%) or citric acid (0.5%, 0.56%, 0.60% or 0.66%) was added to pork sticks to determine their effects on microbial growth, sensory evaluation, and shelf life when stored frozen (-20°C), refrigerated (2°C), or at room temperature (22°C). Two raw materials, pork blade meat (shoulder meat; 91% lean, 9% fat) and regular 80:20 pork trim (80% lean, 20% fat) were used. The consumer panel preferred lean pork sticks made from blade meat over high-fat pork sticks made from regular 80:20 …
