Abstract

The invention discloses a method for extracting a peanut shell yellow pigment. The method comprises the following steps: sterilizing the peanut shell powder and adding sterile water and mixed bacteria for solid-state fermentation; adding water to the fermentation product, performing microwave assisted leaching, and centrifuging to remain the liquid supernatant; and concentrating the liquid supernatant in vacuum, and performing CO2 supercritical fluid extraction to obtain the yellow pigment. The method is different from the existing peanut shell yellow pigment extracting method in which the biological and physical methods are combined, firstly, the peanut shell is fermented by use of microorganisms so that macromolecular substances in the peanut shell can be hydrolyzed and the yellow pigment can be leached smoothly, secondly, the yield of the yellow pigment is increased by virtue of microwave assisted leaching, and finally, the CO2 supercritical fluid extraction is adopted to improve the purity of the yellow pigment and further increase the yield. According to the method, the peanut processing byproduct peanut shell is taken as the raw materials, the extraction process is environmentally friendly, and the obtained yellow pigment is high in purity, yield and color value, has an anti-oxidation effect and can be applied to the food industry as a natural pigment and a natural antioxidant.

Description

technical field [0001] The invention relates to a method for extracting peanut shell yellow pigment, which belongs to the technical field of extracting natural pigment from peanut processing by-products. Background technique [0002] China is a major producer of peanuts in the world, with an annual output of nearly 4.5 million tons of peanut shells. Apart from a small portion of these peanut shells being used as raw materials for papermaking and chemical products, or as feed, most of these peanut shells are used as fuel or abandoned farmland, causing Great waste of resources. Peanut shells account for about 30% of the mass of peanuts, which mainly contain hemicellulose and crude cellulose, the content of hemicellulose is 10.1%, and crude cellulose accounts for about 65.7% to 79.3% of the mass of peanut shells. Other nutrients in peanut shells include crude protein 4.8%-7.2%, crude fat 1.2%-1.8%, reducing sugar 0.3%-1.8%, disaccharide 1.7%-2.5%, pentose sugar 16.1%-17.8%, st...
