Problems solved by technology

Passion fruit shell accounts for 45-60% of the whole fruit weight, contains a large amount of pigment, and becomes a by-product in a large amount of passion fruit juice processing, and these processing by-products are mostly discarded as waste, causing a great waste of resources, and also burden on the environment

Abstract

The invention provides an extraction method and application of passion fruit pigment. Peels of the whole fruits of bad passion fruit waste or waste fruits of passion fruit in the processing industry are cleaned, the fruits are chopped to be mixed with water, and mixed liquid is obtained; the pH value of the mixed liquid is conditioned through glacial acetic acid or sodium carbonate, then extraction is conducted for 0.5-3 hours at the temperature of 40-60 DEG C, the product is filtered, and the filtrate is stored for dyeing real silk; and the dyeing method of real silk comprises the steps thatthe real silk is taken to be dyed for 20-40 minutes at the temperature of 40-60 DEG C with the bath ratio being 1 to 30-50 (mass ratio) and the pH value being 4-9 by adding 2-10% (omf) (relative to the weight of textile fabric) of white alum.

Description

technical field [0001] The invention belongs to the field of biological extraction, in particular to a method for extracting passion fruit pigment and its application. Background technique [0002] Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc. Silk is a protein fiber. Silk fibroin contains 18 kinds of amino acids that are beneficial to the human body. It has a good affinity with human skin and is known as the "Fiber Queen". Silk garments made of silk fibers are naturally draped, light and elegant, elegant and luxurious, and have always been treasures in clothing consumption. [0003] Natural dyes originate from nature and mainly exist in the flowers, fruits, skins, stems, leaves and roots of plants. They are harmless to human health, have high wearing safety, are biodegradable, and have good compatibility with the environment. It will pollute the environment and meet the requirements of modern people for their own heal...
