Abstract
The invention relates to the production for health-caring food, in particular to glycoprotein of yam and an ultrasonic auxiliary extraction method thereof. The product contains 60-70% of the glycoprotein of yam. The glycoprotein is a mixed product and the main composition thereof is a neutral glycoprotein composition and an acid glycoprotein composition, respectively with the molecular weight of 89,381Da and 47,412Da and respectively with the proportion in the product of 40-46% and 14-18%. The method of the invention comprises the steps as follows: slicing the dry yam, crushing the yam, pulse ultrasonic auxiliary extracting with water, depositing with ethanol, centrifugal collecting and depositing, drying under low temperature and obtaining the glycoprotein of yam; alternatively, the fresh yam is crushed into slurry and the pulse ultrasonic auxiliary extraction is directly carried out so as to obtain the glycoprotein of yam; the obtained glycoprotein of yam has the effects of regulating immune, tumor inhibition, reducing the blood sugar and the blood lipid, oxidation resistance, anti-aging, etc.
Description
Technical field
The present invention relates to the development and use field of medicinal plant product, be specifically related to health food production, refer in particular to the method for the ultrasonic assisted extraction of a kind of Chinese potato glucoprotein.
Background technology
Contain a large amount of starch and protein, vitamin, polysaccharide, glycoprotein, bile alkaline, allantoin etc. in the Chinese yam, nutritive value is very abundant.
Chinese yam is with a long history in China's plantation, is medicinal material, is again nutritive health-care vegetable.Provinces such as Henan, Jiangsu, Guangxi have abundant Chinese yam resource.Chinese yam has very high value of exploiting and utilizing, but Chinese yam is except that part is medicinal at present, and majority is used to eat raw, also has a spot of Chinese yam elaboration products to occur, but small.On the whole, the level of Chinese yam processing at present is low relatively, and product exploitation deeply degree is not enough, and kind is single, and the product added value is not high.In recent years, also have some deep developments to utilize the achievement of Chinese yam to deliver both at home and abroad, comprising the Chinese yam starch utilization, Chinese yam polysaccharide extracts and utilizes or the like.Traditional extracting method ubiquity extraction time is long, solvent-oil ratio is big, extract the temperature height, the low inferior problem of extraction efficiency.Studies show that in recent years, the effect of physical fields such as ultrasonic or microwave can improve the deficiency that traditional extraction process exists really.New through looking into, domestic and international research report or the patent disclosure of not seeing Chinese potato glucoprotein impulse ultrasound assisted extraction method as yet.
Summary of the invention
The present invention is to provide a kind of Chinese potato glucoprotein product, this product contains Chinese potato glucoprotein 60%～70%.Chinese potato glucoprotein has the immunity of adjusting, suppresses tumour, reduces blood sugar, blood fat, anti-oxidant, the health care effect of waiting for a long time.This glycoprotein is a kind of mix products, and main component is a kind of neutral glycoprotein component and a kind of acidoglycoprotein component, and its molecular weight is respectively 89,381Da and 47, and 412Da, its ratio shared in product is respectively 40%～46% and 14%～18%.
Another object of the present invention provides the preparation method of above-mentioned Chinese potato glucoprotein.
Above-mentioned purpose of the present invention realizes by following technological means.
When being the feedstock production Chinese potato glucoprotein with dried yam slices, adopt following technological process: dry yam slices → pulverizing → impulse ultrasound auxiliary water is carried → precipitation with alcohol → centrifugal collecting precipitation → low temperature drying → Chinese potato glucoprotein.
The ultrasonic auxiliary water of being mentioned in the said method is carried and being operating as: the running water dissolving that adds 20～100 times of dried yam flour weight in the yam flour after degreasing, adopt impulse ultrasound auxiliary extraction technology extraction Chinese potato glucoprotein wherein, the condition of extracting is: 10～55 ℃ of feed temperatures, extraction time 20～80min, the parameter that used pulsed applies ultrasonic energy is pulse fabric width 1～5s, pulse spacing 1～7s, feed liquid is passed through ultrasonic probe in the mode of circulation.When adopting the Chinese potato glucoprotein in the precipitation with alcohol Chinese yam water extract, concentration of alcohol is 20%～90%.
When being the production Chinese potato glucoprotein of raw material with bright Chinese yam, adopt following technological process: bright Chinese yam → making beating → impulse ultrasound auxiliary water is carried → precipitation with alcohol → centrifugal collecting precipitation → low temperature drying → Chinese potato glucoprotein.Wherein ultrasonic auxiliary water is carried and being operating as: the running water that adds 3～20 times of bright Chinese yam weight in the Chinese yam after making beating, adopt ultrasonic auxiliary extraction technology to extract wherein glycoprotein, it is the same that the ultrasonic auxiliary water of the condition of extraction when being the feedstock production Chinese potato glucoprotein with dried yam slices put forward condition.
The Chinese potato glucoprotein that the present invention prepares has the immunity of adjusting, suppresses tumour, reduces blood sugar, blood fat, anti-oxidant, the health care effect of waiting for a long time.
