ε-Polylysine -- Innovative Solution for Meat Preservation
Over the years, the global meat industry has witnessed bigger scale and more varieties. However, there’re still many producers troubled by food preservation given stricter regulations and customers’ pursuit for healthy food. How to preserve food in summer has become an urgent problem to be solved in the whole food industry.
1. Why Meat Spoil?
(1) Protein decomposition
Amines, produced after protein deterioration and decomposition, are volatile and smelly. For example, putrescine produced from ornithine, tryptamine from arginine, hydrogen sulfide, ammonia and ethanethiol from sulfur-containing amino acids, are the main odor substances produced by protein spoilage.
(2) Carbohydrate decomposition
Carbohydrate deterioration is accompanied by increased acidity, sugar, alcohol, aldehyde, ketone or gas (CO2) depending on different types of food. These substances usually have unique odor.
(3) Fat decomposition
Fat deterioration is accompanied by acid substances and pungent odor, which is common among sausages. After being stored for a long time, the fat gets oxidized, resulting in rancidity.
