Preventive Effect of Fatty Acids and Their Esters against Swelling Spoilage Caused by Lactic Acid Bacteria

Abstract

In the previous report, we have described the effects of monoglycerides against the inflation spoilage. Here, the effects of short chain fatty acids and some surfactants are described. Lauric acid had the highest effect to suppress the gas production among fatty acids tested, and it suppressed the gas production perfectly at the concentration of 0.03%. There were some surfactants which had the suppressive effect at 0.1%. When n-capric acid or monocaprin was combined with them, the suppressive effect was usually higher than that of n-capric acid or monocaprin. But tween 80, span 80 and monoolein contrarily reduced the suppressive effect of n-capric acid or monocaprin. On the addition of any polysaccharide or any protein also reduced the effect.
