A kind of sheep oil degumming method

Abstract

The invention discloses a sheep oil degumming method, which comprises the following steps: adding citric acid solution to the sheep oil raw material, and carrying out acidification treatment under the assistance of ultrasound to obtain acidified sheep oil; adding a certain amount of distilled water to the acidified sheep oil, Adjust the pH and temperature of acidified sheep oil, and add phospholipase A1 for ultrasonic-assisted enzymolysis to obtain sheep oil for one enzymatic hydrolysis; adjust the pH and temperature for one enzymatic hydrolysis of suet, and add phospholipase B for ultrasonic-assisted enzymolysis to obtain Secondary enzymatic hydrolysis of sheep oil; adjust the pH and temperature of the second enzymatic hydrolysis sheep oil, and add phospholipase C for ultrasonic-assisted enzymolysis to obtain third enzymatic hydrolysis sheep oil; perform enzyme inactivation treatment on the third enzymatic hydrolysis sheep oil, centrifuge The oil sample in the upper layer was used to obtain enzyme-inactivated sheep oil; the enzyme-inactivated sheep oil was vacuum-dried to obtain degummed sheep oil. The sheep oil degumming method provided by the invention has safe process and convenient operation.

Description

technical field [0001] The invention relates to the technical field of sheep oil, in particular to a method for degumming sheep oil. Background technique [0002] Since the 1990s, my country's meat production has leapt to the first place in the world. In 2009, my country's meat output was 75 million tons, accounting for about 40% of the world's total output, of which mutton production accounted for 6% of the domestic total meat output, accounting for 37% of the world's total. At present, the development direction of the global sheep industry has shifted from pure wool to meat. my country is a big sheep-raising country. The number of sheep and goats and the total production of mutton rank first in the world. Because of its high protein content, low cholesterol content, rich nutrition, high edible value and warm nature, mutton has a warm after eating. With the effects of warming the body, nourishing the body and warming the spleen and stomach, the market share in the inland a...

Problems solved by technology

[0004] However, due to the high content of colloid in sheep oil, there are a series of adverse effects in the refining and processing of sheep oil. For example, when alkali refining deacidification, oil soap can not be separated well, resulting in refining The consumption increases, and the soap content in sheep oil increases at the same time; when deodorizing, the gum is easy to carbonize, which increases the color of the oil; when decolorizing, it adheres to the surface of the decolorizing agent, reducing the decolorization efficiency, etc., resulting in a decline in the quality of the final product sheep oil
