Problems solved by technology

This method extracts the gardenia yellow pigment from the gardenia fruit, and the color value is higher, and the OD value is lower, and can avoid greening, but, after the gardenia yellow pigment that this method produces is made preparation, can produce when refrigerated A large amount of precipitation cannot fully meet the needs of practical applications, thus limiting its application range

Abstract

The invention provides a production method of a gardenia yellow pigment, which comprises the following steps: a) extracting gardenia fruit powder to obtain a first pigment solution; b) purifying the first pigment solution with macroporous adsorption resin to obtain a second pigment solution; c) performing ultrafiltration of the second pigment solution by an ultrafiltration membrane to obtain a filtrate, wherein the ultrafiltration membrane is an ultrafiltration membrane with a molecular weight cutoff of 20000 dalton-100000 dalton; d) concentrating the filtrate obtained in step c) by a nanofiltration membrane to obtain the gardenia yellow pigment, wherein the nanofiltration membrane is a nanofiltration membrane with a molecular weight cutoff of 100 dalton-500 dalton. When the gardenia yellow pigment obtained by the production method provided by the invention is prepared into a preparation, precipitates are not easy to generated during refrigeration, and the preparation has a wide application scope. In addition, the production method of the gardenia yellow pigment of the invention has a simple process, and high production efficiency, and is applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a production method of gardenia yellow pigment. Background technique [0002] Gardenia yellow pigment, also known as crocin, is a natural pigment extracted from the fruit of gardenia, a medicinal and edible plant of Rubiaceae. Gardenia yellow pigment belongs to water-soluble carotenoids, and its main components are crocetin and crocetin. Gardenia yellow pigment has many advantages such as bright color, strong tinting strength, high stability, almost no effect of pH value, safety and non-toxicity, etc., so it is widely used in the fields of medicine and food, such as the Chinese national standard GB 2760 -The 2011 "National Food Safety Standard Food Additive Use Standard" stipulates that gardenia yellow pigment can be used in foods such as flour products, candies, cakes and beverages. At present, gardenia yellow pigment has a wide market demand in Japan, South Korea and Southea...
