Preparation method of apple seeds protein

Abstract

The invention relates to a method for preparing protein by using residues of materials after fat extraction, especially the vegetables and fruit seed with high protein content, especially to a method for preparing apple seeds protein. Apple seeds has high content of oil and has a protein content of 46.0%. Thus apple seeds have high exploitation value. There is no report about the preparation method of apple seeds protein in our country and abroad. The steps of the method are: apple seeds residue obtain from hyper-criticality CO2 flow extraction-crushing-extracting with lye-whizzing-stagnating with acid-whizzing-spray-drying to obtain apple seeds protein. The method is suitable for the extraction of apple seeds protein. Apple seeds protein can be extracted efficiently by the method of the invention at a yield of 50.41%.

Description

Technical field: [0001] The invention relates to the preparation of protein from the oily residue of oil-containing materials, especially fruit and vegetable seeds with high protein content, specifically a method for preparing apple seed protein. Background technique [0002] my country is rich in apple resources. At present, my country's total apple planting area is nearly 30 million mu, with an annual output of 22 million tons of apples, accounting for nearly 50% of the world's total output. It is the world's largest producer. Due to my country's unique resource advantages, the fruit juice processing industry has developed rapidly in recent years, and the production capacity has soared from less than 1,000 tons in the mid-1980s to more than 400,000 tons today. There are about 6 million tons of apples used for processing in the country every year, about 2 million tons of pomace are excreted, and about 25,000 tons of apple seeds can be obtained every year. [0003] Compared...
