Description
Technical field: the present invention relates to a kind of method and technology of preparing thereof of utilizing the cold press ansu apricot benevolence dregs of rice to produce ansu apricot benevolence separated protein powder, belong to the vegetable protein manufacture field.
Background material: the food that protein isolate is a kind of purity of protein height (protein content is up to more than 90%), have an excellent machinability adds the intermediate raw material of articles for use; be widely used in meat product, dairy products, cold food cold drink, bakery product and health food etc.; the protein isolate of accomplishing scale production at present mainly is soybean protein isolate (Lei Shufang etc., 2004).And report is not seen in the research of the protein isolate of ansu apricot as yet.It is heavy method of the molten acid of alkali and membrane separation process that the method for protein isolate production at present mainly contains two kinds.According to the study, the soybean protein isolate product quality that these two kinds of methods are produced respectively has characteristics (Liu Dachuan etc., 2003), but membrane separation process production investment is big, specification requirement is high.This patent adopts the preparation method of the heavy method of the molten acid of alkali that meets present national conditions as the almond protein isolate.
Just reported that as far back as Cruess in 1958 Germany and the U.S. utilize semen armeniacae amarae to produce semen armeniacae amarae oil condition (Cruess, W.V., 1958), Hallabo in 1975 etc. have studied the physicochemical characteristic (Hallabo of amygdalate physics, chemical characteristic and almond oil, S.A.S., 1975), the same year, Khairy then studied the biological value of almond cookie, and Moussa﹠amp; The biological value that Abo-Baker studied almond protein in 1980 (Moussa et al, 1980).M.H.Abd El-Aal equals to study comparatively all sidedly in 1986 semen armeniacae amarae proteopepsis, physicochemical characteristic and functional characteristic, think that semen armeniacae amarae albumen has the physicochemical characteristic of typical vegetable protein, mainly form by digestible metabolism protein, has higher edibility, the good function characteristic that the almond protein of detoxification simultaneously powder is had makes it can be used for cake production (Abd E1-Aal M.H.et al, 1986).
Musa Ozcan has studied the semen armeniacae amarae oil composition of ansu apricot different cultivars production respectively and has comprised the difference (MusaOzcan of other composition of protein in 1998,1998), aspect the component of research almond protein, W.J.Wolf etc. utilize the ultracentrifugation technical point to obtain 2s from the almond protein powder, 9s, 14s and 19s be totally four kinds of compositions, wherein 14s is main the composition, account for about 70% of total protein content, think that this is the amandin (amandin) corresponding to the document indication, and the minimum solubility of almond protein powder appears at (W.J.Wolf et al between the pH3-5,1998), history Tsing-Hua University equals to study in 2002 the amino acid composition of semen armeniacae amarae albumen, think that semen armeniacae amarae is a kind of natural dry fruit resource (history Tsing-Hua University etc., 2002) that is rich in amino acid and helps human amino acid's nutrient balance and health-care effect.At present the almond produced of China is except that European countries such as a large amount of outlet Germany, Britain, Holland, and domestic processing mode is processed almond dried food and nuts, almond can, almond milk on a small quantity mainly based on oil expression.Especially the almond dregs of rice that extract oil later are rich in protein (42.9%～44.5%), have very high nutritive value and value of exploiting and utilizing (Chang Yingjie etc., 1996), but rationally do not utilized, not only wasted resource, and be unfavorable for improving the value of ansu apricot product, improve orchard worker's income (Song says and admires etc., 2006).
Ansu apricot is the famous large forest products resource of China, and economic worth is high.Almond promptly obtains the almond dregs of rice after extracting grease, the unmodified ansu apricot benevolence dregs of rice that take off are good vegetable protein sources, and protein wherein and amino acid content are abundant, and protein content can be enriched to 35%-45%, and amino acid combination approaches the needs of human body, sees Table 1:
Amino acid whose composition and content (%) in the table 1 almond dregs of rice
| Essential amino acid | Other amino acid | ||||||
| Ile Leu Lys Met | 1.4 2.8 1.3 0.5 | Phe Thr Trp Val | 2.0 1.2 1.7 1.8 | Tyr Arg His Ala | 1.4 3.8 1.2 1.9 | Asp Gly Pro Ser | 4.6 2.3 1.7 1.7 |
Although ansu apricot benevolence albumen is good edible protein resource, often cause the very big wasting of resources owing to processing technology is unreasonable.Usually, what everybody paid close attention to is the toxicity of ansu apricot benevolence, and therefore, what at first expect is the detoxification of ansu apricot benevolence, hardly realizes particularly boiling water infusion technology of preceding detoxification process, is easy to cause the sex change of almond protein, thereby the value of almond protein is reduced.
This shows, it is extremely urgent to utilize ansu apricot benevolence grouts to develop instant reinforcement separated protein powder, we should develop corresponding product in conjunction with the domestic and international market demand, particularly easily accumulating, reconstitute conveniently, nutritious, almond separated protein powder product that mouthfeel is unique, good resource is become the high added value commodity, thereby realize the conversion of resources advantage to economic advantages.
Summary of the invention: purpose of the present invention is exactly at the deficiencies in the prior art, provides a kind of method and technology of preparing thereof of utilizing the cold press ansu apricot benevolence dregs of rice to produce ansu apricot benevolence concentrated protein powder to people.For achieving the above object, the present invention adopts the following technical proposals preparation.
