Specially for infant and pregnant woman. Then the purpose of this experiment is: To be added the extra-folate to goat*s milk can compensatethe nutrition shortage. By the way, it also can probe folate degradation when goat*s milk is producing and storage. And how to effect the quality of long life goat*s milk after folate added. What we adopt for this experiment is raw goat milk. After added folate: 0, 1, 2,4, or 8 ug/ml individually , poured in the commercial andlight isolation glasses bottles. Then, pre-heat by 60OC. After all, sterilize by 121oC for 15 minutes and inspect the changement of quality of goat mild every month during the 4-month- storaged . the inspect itemsare including : sediments, Ph, browning degree, viscosity, titrable acidity, fat, proteins, lactose as well as degradation and light effectof folate. Our experiment shows that it will not have bad influence on variousquality of goat milk when folate contented in long life goat milk in poor proceed condition. As to the folate degradation, there*s noinfluence on folate by commercial or light isolation package. But the degradation by light isolation package is only about 5.5% in the first month, and it reaches to about 16% by commercial package. Then, after4-month storage, the degradation by light isolation go up about 9.5% andabout 25% by commercial package.
