Description

One functional mixed short peptide and preparation method thereof of cultivating peanut
Technical field
The present invention relates to biologically active peptides and preparation method thereof, particularly relate to the functional mixed short peptide and preparation method thereof of cultivating peanut.
Background technology
Main application at China's peanut is oily usefulness, and national peanut has 50% to be used to oil expression approximately, and along with the popularization of advanced milling process such as cold-press, aqua method, oil in the peanut and albumen can be utilized simultaneously.The development and use of China's Semen arachidis hypogaeae protein are started late, and the intensive processing technology is backward relatively, and product-mix is single, and is of low grade, and fabricated product lacks high in technological content deep processing, high-grade product still based on preliminary working.At present, the Semen arachidis hypogaeae protein product on the domestic market mainly is the powdery Semen arachidis hypogaeae protein, and its main application is as the basic material in the food-processing.Powdery Semen arachidis hypogaeae protein work in-process exists functional property and physiologically active is relatively poor, absorb shortcomings such as relatively poor, and it is imperative therefore to research and develop the Semen arachidis hypogaeae protein deep processed product with good function character and physiologically active.
Biologically active peptides (biologically active peptides or biopeptides) is meant the peptides that the vital movement to living organism is useful or have physiological action.Modern nutrient research shows: protein is in digestive tube under the digestive ferment effect, the hydrolysis end product is total free aminoacids and peptide, and being absorbed and used with complete form, but not former being absorbed of being thought of people with the total free aminoacids form by the small peptide that several amino-acid residues are formed.The contrary concentration gradient of little peptide is according to H +Concentration or Ca 2+The active transport process of concentration has the dependent non-power consumption Na of pH +, H +Exchange system, little peptide movement system have that transport speed is fast, power consumption is low, it is saturated to be difficult for, and absorb the characteristics of uncontested property and inhibition between each peptide.
The approach of the production preparation of bioactive short peptide has three: the one, from natural organism, extract the various natural radioactivity peptide matters of itself inherent; The 2nd, the approach by protein degradation obtains biologically active peptides with various physiological functions; The 3rd, use synthetic method and prepare biologically active peptides.Exist biologically active peptides in the natural biological body, but it is higher to extract the biologically active peptides production cost from the natural biological body, and biologically active peptides content in vivo is generally very low, is difficult to realize large-scale production with various physiological functions; Synthesis method can be by the synthetic any bioactive peptide of people's wish, but cost height, side reaction reach the development that problem such as residual toxic compounds is restricting this technology more.
Summary of the invention
The purpose of this invention is to provide the functional mixed short peptide and preparation method thereof of cultivating peanut.
Peanut functional mixed short peptide provided by the present invention, the weight percentage of peptide is higher than 80%, ash oontent≤8%, sugared content≤5%, weight loss on drying≤7%, fat≤5%; Molecular weight is less than small peptide content 〉=60% of 1000Da; Trichoroacetic acid(TCA) nitrogen soluble index 〉=99.5%.
