Description

A kind of yam extract of enrichment various trace elements and preparation method
Technical field
The present invention relates to a kind of yam extract and preparation method of enrichment various trace elements, belong to agricultural product intensive processing field.Prepared yam extract can be used as food additives, health food and cosmetic additive agent.
Background technology
Chinese yam is Dioscoreaceae plant Chinese yam (Dioscorea opposite Thunb.), the original name Chinese yam, and the beginning is stated from Shennong's Herbal, classifies as top gradely, and " it is sweet to distinguish the flavor of, temperature to call it.Qi-restoratives is won, is removed fever and chills perverse trend, tonifying middle-Jiao and Qi power, longue meat, obeys normal hearing and eyesight for a long time." " medicine justice " cloud: " survivor is cool in nature, and ripe then change cold is a temperature for Chinese yam.Temperature compensation and not rapid, little perfume (or spice) and drying has been followed the merit of transferring benefit is controlled chronic cough of deficiency lung, and is what reliable.Because of its sweet gas perfume (or spice) of distinguishing the flavor of, help spleen with it.Control insufficiency of the spleen diarrhoea, tiredness with somnolence, four limbs are sleepy.Get its then yang-tonifying again, with the energy tonifying middle-Jiao and Qi, temperature is supported muscle, is lung spleen two dirty key medicines.”
Modern scientific research clearly (Xie Xingyuan. main component of Chinese yam and using value thereof. modern agriculture science and technology, 2009, (6): 76-77), Chinese yam stem tuber (root-like stock) is nutritious, remove and contain multiple nutritional components such as multiple kinds of carbohydrate, fat, protein, vitamin, trace element, also have tens seed amino acids of needed by human body.Fresh Chinese yam is from component content, moisture about 70%～80%, about starch 16%, polysaccharide (mannose, glucose and galactolipin etc.) be about 2.5%, protein 1.5%, other micro constitutents have vitamin (with Vc, VB, riboflavin, Buddhist nun's acid, carrotene, thiamines etc. are main), inorganic elements (comprises Ba, Be, Ce, Co, Cr, Cu, Ca, Li, Mn, No, Ni, P, Sr, Zn etc., wherein P content is the highest), phytic acid, (stem tuber contains Dioscin to saponin(e, can get diosgenin through hydrolysis), allantoin, choline, end the wooden fork element, phenolic substance (polyphenol oxidase, hand over tea phenol amine, 3,4-dihydroxy benzenes ethamine, dopamine, hydrochloric acid Chinese yam alkali, the plain I of Chinese yam, II, III, IV, V, the acerin II, cholesterine, ergosterol, campesterol, cupreol), iodine matter etc.In fact, Chinese yam is rich in polysaccharide, can increase blood leucocyte, strengthens leukocytic phagocytic function, thereby to promoting specific immunity and non-specific immune function that better effect is all arranged.But, the contained inorganic elements Fe of Chinese yam, Zn, Cu, Mn, Ca, various trace elements such as Mg, Se, to improving the human body different physiological roles, particularly improving immunity of organisms also has positive role.
About the patent application of Chinese yam intensive processing or authorize and had multinomially, be alcohol extracting and the purification with macroreticular resin engineering that 200410016839.0 patent " extracting method of RHIIZOMA DIOSCOREAE frOm Henan of China extract RHIIZOMA DIOSCOREAE frOm Henan of China saponin(e " relates to dioscin at present as application number; Application number is that 200610069598.5 patent " is extracted the method for polysaccharide and allantoin " and adopt the high pressure extraction Chinese yam polysaccharide from Chinese yam, and that continues uses the ultrasonic extraction method allantoin; Application number is 200610085512.8 patent " preparation process of Huai Chinese yam polysaccharose and uses thereof ", and the water that its main preparation method mainly is a Chinese yam polysaccharide extracts and the alcohol precipitation obtains purified product; Application number is that 200710068184.5 patent " a kind of processing technology of Chinese yam comprehensive utilization " relates to dehydration yam slice, yam flour and Chinese yam epidermis and discarded object extracts the technical process of total steroidal saponin unit.
There is following shortcoming in these methods: leaching process is only emphasized one-component, as Chinese yam polysaccharide, glycoprotein, saponin(e or allantoin, does not consider the utilization of various trace elements in the Chinese yam; Technology is various, the cost height, and the product yield is low, is difficult to realize industrialization.
Summary of the invention
For overcoming the shortcoming of above-mentioned Chinese yam deep process, the invention provides a kind of yam extract and preparation method of enrichment various trace elements.
Manufacture craft process of the present invention is as follows:
Bright Chinese yam is made yam pulp through clean, making beating, separation after removing residue, or be raw material with the yam flour, extract with alkaline aqueous solution, supernatant is reclaimed in centrifugation; With this supernatant of acid neutralization, carry out vacuum then and concentrate then, spray-dried or freeze drying promptly gets yam extract.
Specific operation process:
(1) the bright Chinese yam stem tuber of selection smooth surface, profile rounding, no disease and pest, clean peeling, be cut into the thick yam slice of about 5mm, drop into yam slice in the colour protecting liquid (the D-arabo-ascorbic acid sodium water solution that contains 0.3% citric acid and 0.1%) of preparation in advance rapidly, soaked 45 minutes, take out yam slice, use distilled water flushing 2 times;
(2) yam slice of peeling is put into boiling water and boiled 6 minutes, take out the Chinese yam after boiling, put into beater, in yam slice (dry weight) 1: 6 (g/mL) pure water of ratio with water, vitaminize C sodium salt (consumption be Chinese yam stem tuber weight 0.02%), making beating separates and removes residue and get yam pulp.
(3) add dilute alkaline soln (with NaOH or Na by the Chinese yam dry weight and the aqueous solution than 1: 10～1: 12 (g/mL) 2CO 3The pH of water transfer solution is 8～9.5), extracted centrifugal collection supernatant 100～120 minutes down for 50～60 ℃ in temperature.Filter residue repeats to extract once, merges centrifuged supernatant twice.
(4) with this supernatant of gained with the acid neutralization, vacuum concentrate relative density 1.2～1.4 thick concentrates; Freeze drying temperature-30～-40 ℃, 12～20 hours time.180～170 ℃ of spray-dired condition inlet temperatures, 90～80 ℃ of outlet temperatures.
Be scattered on the polysaccharide carrier with Dioscin, allantoin, potassium, calcium, magnesium, iron zinc and selenium in the gained yam extract of the present invention, content is even, has kept multiple micro-composition with health care in the Chinese yam, and can keep the nutritional labeling in the Chinese yam.This extraction process process is simple, and operating cost is low, and not with an organic solvent, remaining residue can be used for preparing the Chinese yam starch compound sugar.
