Abstract

The invention discloses a method for preparing insoluble dietary fiber from olea europaea pomace, and belongs to the field of food processing. The method comprises the steps that olea europaea pomace oil and degreased olea europaea pomace are obtained by taking the olea europaea processing waste pomace as a raw material through the processes of smashing, degreasing and the like, and then the degreased olea europaea pomace is prepared into the high-purity insoluble dietary fiber through the processes of alkaline extracting, decoloring, washing, drying, smashing the like. According to the preparation method, the high-quality insoluble dietary fiber is prepared from the olea europaea pomace, therefore, waste utilization of the olea europaea pomace is achieved, and an olea europaea industry chain is lengthened to increase the added economic value of the products of the olea europaea pomace.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a preparation method of olive pomace insoluble dietary fiber. Background technique [0002] Olive belongs to the Oleaceae family, also known as foreign olive and olean fruit. It is a world-renowned woody edible oil economic tree species, mainly distributed along the Mediterranean coast. Since the 1960s, my country began to introduce olives, mainly planted in Gansu, Sichuan, Yunnan and other regions. [0003] Olive pomace is the waste residue of olives after being pressed and processed. Except for some used as feed and fertilizer, most of them are directly discarded, which not only causes a waste of resources, but also pollutes the environment. In fact, olive pomace is rich in dietary fiber, and also contains various active ingredients such as triterpenoids and flavonoids. At present, the research focus on olive pomace at home and abroad is mainly to extract and separate polypheno...
