Influence of liposome-encapsulated Neutrase and heat-treated lactobacilli on the quality of low-fat Gouda-type cheese

SUMMARY Low-fat Gouda-type cheese (200 g fat/kg dry matter) was made on a pilot plant scale from cheesemilk to which heat-treated lactobacilli and/or Neutrase encapsulated in dehydrated rehydrated vesicles had been added. In cheese containing added Neutrase, there was increased proteolysis after the first day following cheesemaking. The cheese with added heat-treated lactobacilli developed increased amounts of amino N as well as increased amounts of acetaldehyde and other, unidentified, volatile compounds. The addition of heat-treated lactobacilli also influenced the texture of the cheese which was firmer but less cohesive.
