Solid-in-Oil-in-Water Emulsions for Delivery of Lactase To Control in Vitro Hydrolysis of Lactose in Milk.

摘要: There is an established need to deliver lactase in milk retain activity during storage and hydrolyze lactose after ingestion. In this work, spray-dried powder was encapsulated solid-in-oil-in-water (S/O/W) emulsions fabricate delivery systems. The adoption of Span 80 fat lecithin protein solution enabled the encapsulation ∼76% <400 nm droplets. Additional cross-linking proteins on droplets by transglutaminase addition sodium caseinate effectively reduced amount free spray drying emulsions. Compared data for lactase, significantly improved thermal stability level hydrolysis a 14 day refrigeration (from ∼70 <20%), gradual release simulated gastric intestinal digestions, resulted most digestions. Therefore, studied S/O/W have potential lactose-intolerant consumers.
