Abstract
A β-D-galactosidase which is encapsulated with fatty acid ester, does not exert its hydrolysis function in milk but hydrolyze lactose in the human body. Hence, the milk containing the encapsulated β-D-galactosidase, does not change in sweetness with storage and is digestible to the β-D-galactosidase-deficient people. In addition, the milk can maintain its characteristic taste without off-flavor by virtue of the excellent feature of fatty acid ester.
Claims6
A microencapsulated β-D-galactosidase, in which a mixture of decaglycerin monostearate (PGMS) and distilled water at a ratio of 5:4 is used as a coating agent for microencapsulation, prepared by the steps of:
- mixing and stirring the coating agent and β-D-galactosidase at a ratio in the range of 15:1 to 20:1;
- spraying the mixture to a dispersant containing a fatty acid ester using a spray gun;
- centrifuging the resulting solution;
- mixing the supernatant and the dispersant with an equal volume;
- and
- centrifuging the resulting mixture.
In a material encapsulated with medium chain triglyceride (MCT) as a coating agent, a microencapsulated β-D-galactosidase prepared by the steps of:
- mixing and stirring the coating agent and β-D-galactosidase at a ratio in the range of 15:1 to 20:1;
- spraying the mixture to a dispersant containing a fatty acid ester using a spray gun;
- centrifuging the resulting solution;
- mixing the supernatant and the dispersant with an equal volume;
- and
- centrifuging the resulting mixture.
A microencapsulated β-D-galactosidase, in which a mixture of PGMS and MCT at a ratio of 5:5 is used as a coating agent for microencapsulation, prepared by the steps of:
- mixing and stirring the coating agent and β-D-galactosidase at a ratio in the range of 15:1 to 20:1;
- spraying the mixture to a dispersant containing a fatty acid ester using a spray gun;
- centrifuging the resulting solution;
- mixing the supernatant and the dispersant with an equal volume;
- and
- centrifuging the resulting mixture.
