ABSTRACT: The experiment adopts complex coacervation to
prepare microcapsules. Through the experimental comparison, soybean protein
isolated-maltodextrin is determined as the wall material for the experimental
preparation of the microcapsules of kiwi fruit seed oil. This paper researched
the effects of wall material concentration, core wall ratio and other factors
on complex coacervation of kiwi fruit seed oil microcapsules embedding rate,
determining that the best wall material concentration is 1%, core wall ratio is
1:1, and the optimum pH ratio is 3.0, temperature is 40°C, and the optimum curing time is 6 hours. The experiment carried out half
life research on the microcapsules prepared by the complex coacervation of kiwi
fruit seed oil microcapsule. By calculation: the degradation rate constant of
kiwi fruit seed oil microcapsules prepared by complex coacervation is 2.793.
According to the regression equation it can calculate the half life of kiwi
fruit seed oil microcapsules is 18.58 months, about a year and a half.
