Abstract
The suitability of gellan, κ-carrageenan and a high-melting-fat-fraction of milk fat (HMFF) to encapsulate protease enzymes (Flavourzyme) and impact in accelerating Cheddar cheese ripening were studied. The rates of enzyme entrapment were 48.2%, 55.6%, and 38.9% for gellan, κ-carrageenan and HMFF, respectively. The enzyme capsules were incorporated into milk during cheese manufacture. The moisture content of cheeses with added gum capsules was higher than control cheeses. Casein (β) degradation was monitored by High-Performance Capillary Electrophoresis. All cheeses treated with encapsulated enzyme showed higher rates of proteolysis than the control cheese throughout the ripening period. The rate of proteolysis was greater with cheeses made incorporating κ-carrageenan capsules containing protease. Cheese texture and sensory quality were not significantly influenced by the type of encapsulating material (gum or milk fat). Differences in textural and sensory quality between treated and control cheeses were consistent with release of protease enzymes from capsules.
