Abstract

The invention discloses a method for extracting phytic acid from jatropha curcas seed cakes or jatropha curcas seeds, and the phytic acid is prepared by using the jatropha curcas seed cakes or the jatropha curcas seeds, the oil which is extracted, as raw materials and adopting the steps as follows: lixiviating with diluted acid, removing impurity, neutralizing with alkali, splitting with acid, ion exchanging, decoloring and concentrating. The invention can also be used for preparing feed protein while prepaing the phytic acid, and has high yield and better purity. The extraction rate of the phytic acid is more than 80 percent, the yield of the phytic acid reaches 8-9 percent, and the prepared phytic acid is concentrated liquid with concentration reaching 50-60 percent. After the phytic acid is extracted, the content of crude protein in the residue is further concentrated and improved to reach 25-30 percent; the in vitro digestibility coefficient of the crude protein reaches 43.57 percent and is improved by about 150 percent, compared with the in vitro digestibility coefficient of the crude protein of the seed cakes the phytic acid of which is not extracted. The invention has simple process, wild condition and low energy consumption, meets the requirement of the environment protection, and is a green process of comprehensively utilizing the jatropha curcas seed cakes or jatropha curcas seeds.

Description

technical field [0001] The invention relates to a method for extracting phytic acid, in particular to a method for extracting phytic acid from Jatropha curcas cake or Jatropha seeds. Background technique [0002] Jatropha curcas, also known as Jatropha curcas, stinky tung tree, tung oil tree, false peanut tree, etc., belongs to Euphorbiaceae (Euphorbiaceae) Jatropha genus, is a kind of fast-growing tree species that is resistant to drought and barrenness. It has important development and utilization value in terms of soil organic matter, restoration of vegetation and prevention of rocky desertification. The oil content of Jatropha curcas seeds is between 40%-60%, and the main components are oleic acid (41.3%), linoleic acid (31.4%) and palmitic acid (19.5%), which is an ideal raw material for preparing biodiesel. According to expert research, the average yield of dried wild Jatropha curcas is about 660kg / mu, and 180-270kg of biodiesel can be extracted and processed. This bi...
