Abstract
The invention relates to an extraction method of maize peel yellow pigment. The extraction method comprises extracting maize peel used as a raw material, filtering, concentrating and drying to obtain the maize peel yellow pigment. The maize peel yellow pigment extracted by the extraction method provided by the invention has the functions of promoting human body growth and development, protecting sight, protecting epithelial tissues, improving immunity, prolonging life and the like, therefore the maize peel yellow pigment is a colorant and a health-care product. The extraction method provided by the invention has the advantages of simple process, low cost of raw material, environmental friendliness and no pollution, and can sufficiently utilize resources.
Description
Technical field
The present invention relates to belong to farming, secondary product of forestry deep processing field, be specifically related to a kind of extracting method of maize peel yellow pigment.
Background technology
(Latin title Zea maysl English name is Maize to corn.Corn) another name maize, Bao Lu, maize, maize, ear of maize, beautiful water chestnut, maize, maize, reed broomcorn millet, Zea mays, big chinese sorghum, maize, beauty wheat, seed of Job's tears bag, kind wheat etc., corn is a Monocotyledonae, Poales, Gramineae annual herb plant, plant height 1～4.5m, bar is cylindrical.Originating in Central America, is the staple food crop that American Indian cultivates, happiness high temperature, the 17th century is imported China into, and the corn ultimate production of China is stabilized in more than 1.3 hundred million t in recent years, accounts for global total amount amount about 20%, follow hard on and be not sure to occupy the second in the world afterwards, corn price is cheap.Maize peel is a by product of producing W-Gum, is that raw material extracts edible flavochrome with it, for a new way has been opened up in the deep processing of corn product.
Maize peel yellow pigment main component is β-Hu Luobusu zeaxanthin, cryptoxanthin, xenthophylls etc., belongs to carotenoid (being the isoprenoid pigment), this type of pigment safety non-toxic; be of high nutritive value; can be converted into vitamin A in the human body class, have the human body of promotion and grow, the protection vision; the protective epithelium tissue; improve immunizing power, functions such as prolongs life, therefore; the maize peel flavine is a kind of tinting material, is again a kind of healthcare products.
Vivid, the good stability of maize peel flavine color and luster, be a kind of safety and have the natural pigment that nutrition and health care is worth, be food dye by the approval of many countries and regions, China also classifies the maize peel flavine as the edible pigment in " the edible additive use hygienic standard " formulated in 1996, this pigment is mainly used in oil base or fat base food, as butter, oleomargarine, the meat egg-products, bakery product etc., also be applied to water base food in addition, fine as beverage, soup stock, jam, preserved fruit, but also can be applied to medicine, healthcare products etc.
Pigment majority commonly used at present is artificial or half synthetic food color.Because synthetic colour exists chronic toxic side effect and carinogenicity in varying degrees, therefore, toxicological harmless also has the natural food colour of pharmacological action to be subjected to people's extensive welcome.Therefore seek and develop natural food colour to have great importance for guarantee people's health, promotion development of food industry, tankage maize peel with W-Gum factory is a raw material, therefrom extract natural edible flavochrome, open up a new way for the comprehensive utilization of W-Gum factory, be expected to obtain good comprehensive benefit.
Summary of the invention
The present invention discloses a kind of extracting method of maize peel yellow pigment.The safety non-toxic of the maize peel yellow pigment that the inventive method is extracted is of high nutritive value, and can be converted into vitamin A in the human body class; having the human body of promotion grows; the protection vision, the protective epithelium tissue improves immunizing power; functions such as prolongs life; the maize peel flavine is a kind of tinting material, is again a kind of healthcare products, and the extraction process process is free from environmental pollution; the maize peel yellow pigment purity height that extracts, the yield height.
The present invention adopts following technical scheme for achieving the above object:
A kind of extracting method of maize peel yellow pigment is characterized in that: be raw material with the maize peel, through extraction, filtration, concentrated, the dry maize peel yellow pigment that gets, concrete steps are as follows:
(1) get the raw materials ready: maize peel is cleaned, and drying and dewatering is pulverized then, crosses the 40-45 mesh sieve, and the maize peel water content after requiring to dewater is 6-10%;
(2) lixiviate: the maize peel powder after pulverizing is dropped in the extraction unit, add a certain amount of leaching agent, regulating the pH value is 2-4, agitation as appropriate, with carry out twice lixiviate, filtration under the suitable temperature, merge lixiviate filtrate twice, stand-by, collect residual comprehensive utilization of filter, wherein, the solid-liquid ratio of maize peel powder and digestion agent=1:(3-6), extraction time is 1-3h, and extraction temperature is 55～65 ℃;
(3) concentrate: the lixiviate filtrate that step (2) merges is dropped in the thickener, carry out reduction vaporization and concentrate, get concentrated solution, and reclaim solvent;
(4) drying: the concentrated solution drying is obtained the Powdered finished product of maize peel yellow pigment;
(5) after the assay was approved, packing gets final product on request.
The extracting method of described maize peel yellow pigment is characterized in that: described digestion agent is selected from a kind of in 70%～90% acid ethanol solution, the acid mixture of 95% ethanol-acetone.
Beneficial effect of the present invention is:
The inventive method is to be raw material with the by-product waste maize peel that produced in the process of processing W-Gum, therefrom extracts yellow pigment, for comprehensive utilization agricultural byproducts resource has been opened up a new way; With ethanol or ethanol-acetone is extraction agent, extracts the yellow pigment obtain natural edible, is a kind of resource-conserving, environmentally friendly production technology.
