Abstract

The invention discloses a production method of grape seed oil, which belongs to the technical field of the food processing. Grape seeds are cleaned and broken, the moisture content of the grape seeds is adjusted, and the refined grape seed oil is produced through the procedures such as pre-heat treatment, enzymolysis, microwave treatment, post heat treatment, drying, squeezing, alkali refining, hydration, heat-cold treatment, decoloration and filtering. With the production method, the oil yield reaches 95 percent or more, procyanidin extraction rate can reach 60 percent or more, the destroy degree of other ingredients such as oilmeal protein after the oil pressing is small, the quality of the produced grape seed oil is good, and the nutrient components of the grape seed oil is maximally reserved; and particularly, the refining processes such as alkali refining, hydration, heat-cold treatment, decoloration and the like effectively removes different water-solubility and fat-soluble harmful foreign matters in the crude oil, so the quality of the grape seed oil is improved, and the quality guarantee period is prolonged.

Description

Technical field [0001] The invention relates to a method for producing grape seed oil and belongs to the technical field of food processing. Background technique [0002] Grape seed oil is a high-level nutrient vegetable oil, rich in unsaturated fatty acids oleic acid, linoleic acid, linolenic acid, vitamin E, vitamin P, anthocyanins, etc., with high nutritional value. The traditional squeezing process has low oil yield and poor quality grape seed oil. The supercritical extraction process equipment has large investment and high energy consumption, which is not suitable for small oil companies. The organic solvent leaching process is easy to produce solvent residues and has low safety. [0003] The invention overcomes the shortcomings of the prior art and provides a method for producing grape seed oil. Summary of the invention [0004] The invention provides a method for producing grape seed oil. [0005] The technical scheme of the present invention is to clean, crush, adjust mois...
