Abstract

The invention discloses a preparation method of seabuckthorn seed oil microcapsules rich in dietary fiber. Seabuckthorn seed oil rich in linoleic acid and linolenic acid is selected as a core materialof the microcapsules, and modified starch, sodium caseinate and maltodextrin are used as an ordinary wall material, resistant starch, sugar cane extract and isomaltulose which have a blood sugar stabilizing function are added as a functional wall material, through batching, shear emulsification and homogenization, a seabuckthorn seed oil emulsion is prepared, and the effect of the functional wallmaterial on the properties of the emulsion is studied; and through spray, drying and other processes, a seabuckthorn seed oil microcapsule product with high oil-fat embedding rate and rich dietary fiber is obtained. Through in-vitro digestion characteristics study, a digestibility curve of the seabuckthorn seed oil microcapsules rich in dietary fiber is lower than that of white bread reference, and eGI is 60.17. According to the microcapsules, the oxidative stability of the seabuckthorn seed oil is improved, and the application field is broadened.

Description

technical field [0001] The present application relates to the technical field of food production, in particular to a seabuckthorn seed oil microcapsule rich in dietary fiber and a preparation method thereof. Background technique [0002] Seabuckthorn, the dry and mature fruit of Hippophae rhamnoides Linn., is widely distributed in Eurasia and has 9 subspecies, including 5 subspecies in my country. The pulp is the edible part of the sea buckthorn fruit, and the sea buckthorn seeds are inedible, but have high nutritional value. The protein content in seabuckthorn seeds is as high as 25.4%, the oil content is about 8-10%, and other active ingredients such as phytosterols, flavonoids, plant phospholipids, proanthocyanidins and vitamin C are abundant. Seabuckthorn seed oil is designated as "Necessary for Astronautics Day Meal". Internationally, seabuckthorn seed oil is known as "oil gold". China is the main producer of seabuckthorn resources, accounting for 94% of the world's ...
