Sunflower seed oil extracting agent

Abstract

The invention discloses a sunflower seed oil extracting agent. The sunflower seed oil extracting agent comprises, by weight, 100 parts of ethanol, 20-30 parts of castor oil, 5-10 parts of sodium bicarbonate, 2-5 parts of amylase, 0.5-2 parts of ferrous fumarate and 0.02-1 part of citric acid. The sunflower seed oil extracting agent can effectively extract oil from a sunflower seed raw material against the characteristics of the sunflower seed oil, and the above solvent has no toxic side effects, so the recovery process requirements are not strict; and the solvent residual after the extraction is harmless to human bodies, and extracted oil meal can be directly used for feeding livestock and is harmless to the health of the livestock.

Description

technical field [0001] The present invention relates to an extractant. Background technique [0002] Sunflower, an annual herb of Compositae, has another name called sunflower and sunflower. It is native to the southwestern part of North America and has been introduced to my country for nearly 400 years. As an important oil resource, its output is second only to soybeans and cottonseed in the world, and it is one of the top five oil crops. my country's sunflower production areas are mainly distributed in some areas in the southwest and north, and the annual output can reach 1.25×106t. Sunflower seeds are rich in oil. The oil is pure, clear, nutritious, and odorless. It plays an important role in the metabolism of the human body, regulates blood pressure, and lowers serum and cholesterol. It is known as nutritious and healthy oil, and its sales volume has occupied the world The second place of various edible vegetable oils. In Hong Kong, it has accounted for 70% of edible ...

Problems solved by technology

The steam distillation method is easy to destroy the heat-sensitive components in the product; the oil extraction rate is low when the pressing method is used; when organic solvents such as ethane and petroleum ether are used as the extraction agent, due to the toxic side effects of the extraction agent, the recovered solvent and the product contain solvent The residue problem has become a difficult problem in the extraction of sunflower seeds, resulting in a large cost input
