“…Although many carriers have been investigated to encapsulate phytase, most are inorganic, such as zeolite and allophonic nano-clay, which are used for plant or animal feed applications and are either non-food grade or unsuitable for human consumption ( Filippovich et al, 2023 ). A few studies investigated the use of natural food biopolymers to encapsulate phytase, for example, spray drying phytase with whey and guar gum was used to microencapsulate phytase ( Garcia et al, 2019 ). About 90 % of the phytase activity was retained after simulated digestion in encapsulated phytase; however, the thermal stability of enzymes in the microcapsules was not significantly improved and thus could still not be used in hot food applications.…”
