Embodiment 1

[0032] see figure 1 , figure 2 , the process is as follows:

[0033] 1) 80% alcohol percolation extraction: Add 50g of gardenia fruits with a particle size of 3-5mm to A, add 200g of 80% alcohol, extract at 60°C, and extract for 30 minutes each time. For extraction, the pigment extraction rate is calculated according to the slag, the extraction rate=(1-color value in the slag) / total color value in the raw material, the extraction rate and the total extraction rate of each percolation extraction are shown in Table 1 ;

Abstract

The invention discloses a technology for efficiently extracting high-purification yellow pigment from gardenia fruits.Methods of ethyl alcohol circulation percolation extraction, impurity filtration and removal, membrane separation and purification, membrane concentration, spray drying, resin adsorption, alcohol recovery and the like are adopted in the technology.The gardenia yellow pigment and gardenoside in the gardenia fruits can be efficiently extracted and highly purified, and meanwhile alcohol is recycled.The technology comprises the following steps of 80% ethyl alcohol percolation extraction, alcohol recovery from an extracting solution, impurity filtration and removal, membrane separation and purification, membrane concentration and full utilization of permeate.Equipment of the technology is simple, the feed liquid ratio is low, the solvent consumption amount is small, energy consumption is low, the separating cost is low, the technology process is simple, and the quality and the yield of products can be regulated and controlled according to needs.

Description

technical field [0001] The invention belongs to the technical field of plant pigment extraction, and in particular relates to a process for efficiently extracting highly purified gardenia yellow pigment from gardenia fruit. Background technique [0002] Gardenia (scientific name: Gardenia jasminoides Ellis) aliases: yellow gardenia, mountain gardenia, white toad, is the fruit of Rubiaceae gardenia. Gardenia contains saffron glycosides, which can be used as yellow dyes. Gardenia was the most widely used yellow dye before the Qin and Han Dynasties. The fruit of Gardenia contains gardenia xanthin, a ketone substance, and crocin. The substance used for dyeing yellow is crocetin. [0003] Most of the existing industrial production processes of gardenia yellow pigment are crushing dried fruit, extracting gardenia yellow pigment with 10-15 times the solvent, then adsorbing, separating and purifying by resin, and washing repeatedly with organic solvent. This process has the follow...
