Embodiment 1

[0015] Grind 500g of Jatropha curcas seed oil meal by pre-pressing extraction process into 100 mesh powder, dry at 120°C for 3h, take 25g of dried oil meal into a mortar, add 40ml of industrial methanol, and mix and stir at 40°C for 30min. The solid phase of the separated liquid is filtered, and the residual oil residue is steamed to remove methanol to obtain detoxified vegetable protein, which can be used as feed protein. Concentrate the methanol phase to obtain a crude product containing phorbol ester. The content of phorbol esters was detected by HPLC.

Embodiment 2

[0017] Grind 1000g of Jatropha curcas seed oil meal by pre-pressing extraction process into 100 mesh powder, dry at 120°C for 3h, take 50g of dried oil meal into a mortar, add 90ml of industrial methanol, and mix and stir at 35°C for 50min. The solid phase of the separated liquid is filtered, and the residual oil residue is steamed to remove methanol to obtain detoxified vegetable protein, which can be used as feed protein. Concentrate the methanol phase to obtain a crude product containing phorbol ester. The content of phorbol esters was detected by HPLC.

Abstract

The invention relates to a method for removing phorbol esters from Jatropha curcas seed oil by extraction. The method comprises drying Jatropha curcas seed oil meal obtained from pre-squeezing and leaching processes, grinding into powder, mixing with industrial methanol at a weight ratio of 3.5:1.1 at 30 DEG C for more than 20 min, filtering to separate oil meal and methanol phase, collecting the oil meal and heating to remove residual methanol in the oil meal to obtain detoxicated plant protein; and concentrating the separated methanol phase to obtain phorbol ester product. After removing phorbol esters by methanol extraction, the content of phorbol esters in the oil meal is reduced from 1.78% to 0.014%, so that the oil meal can be used in preparing feed proteins.

Description

technical field [0001] The invention relates to a method for preparing feed protein, in particular to a method for extracting and removing phorbol ester from Jatropha curcas seed oil meal. Background technique [0002] After more than 20 years of development, my country's feed industry has made historic achievements. According to statistics, in 2002 the world's total meat output reached 245.05 million tons, of which China's total meat output was 67.85 million tons (65.86 million tons according to the statistics of the Ministry of Agriculture of my country), accounting for 27.7% of the world's total output. my country's meat production , Poultry and egg production, and the total production of livestock products rank first in the world. There is no doubt that my country is the world's largest feed consumer. With the development of the feed industry, the demand for plant-based protein raw materials continues to increase. The increasing shortage of animal protein resources and ...
