Peptide coffee and preparation method thereof

Abstract

The invention relates to peptide coffee using coffee beans as raw materials and a preparation method thereof. The peptide coffee of the invention contains 1-8% of peptides that can be absorbed by the human body, and also contains linoleic acid, linolenic acid, oleic acid, caffeine, VB, Calcium, Iron, Phosphorus, Selenium, Glucose. It roasts coffee beans at a temperature of 80-150°C, crushes them, adds water to make pulp and grinds them to a fineness of 200-300 mesh; and then homogenizes them under high pressure for 2-4 times at a pressure of 40-60Mpa, and then heats them at 135 Grind to more than 300 mesh at a temperature of ~160 °C and a pressure of 7 ~ 8kg, and heat for 35 ~ 40 minutes; finally cool to 30 ~ 55 °C, add hydrochloric acid first, then add lipase and .cellulase. Adjust the temperature to 45-50°C, add bromelain and biochemically again at a constant temperature; the slurry after biochemical temperature is raised to 80-100°C to inactivate enzymes, sterilize, and volatilize the residual hydrochloric acid to obtain the whole coffee peptide stock solution, which is dried to obtain peptide coffee.

Description

technical field [0001] The present invention is a kind of peptide coffee and its preparation method which are produced by using coffee as raw material in modern times using bioengineering technology and modern physics nanotechnology principles. The peptide is a mixture of compounds such as oligopeptides, short peptides and polypeptides. Background technique [0002] Coffee contains rich nutrients: every 100 grams of coffee beans contains 2.2 grams of water, 12.6 grams of protein, 16 grams of fat, 46.7 grams of sugar, 9 grams of cellulose, 4.2 grams of ash, 120 mg of calcium, 170 mg of phosphorus, iron 42mg, sodium 3mg, vitamin B20.12g, niacin 3.5mg, caffeine 1.3g, tannin 8g. And every 100 grams of coffee extract contains 99.5 grams of water, 0.2 grams of protein, 0.1 grams of fat, 0.1 grams of ash, traces of sugar, 3 mg of calcium, 4 mg of phosphorus, 2 mg of sodium, 0.01 mg of vitamin B, and 0.3 mg of niacin. Dissolve 10 grams of coffee in hot water, the content of caffei...

Problems solved by technology

[0006] In order to achieve the above purpose, the following scientific and technological problems need to be solved: one is to solve the problem that protein in coffee is difficult to dissolve; Degradation is easy to convert into a large amount of amino acids and condensed into a small amount of peptides, the conversion rate of peptides is low; the fourth is to solve the problem of three major side effects of drinking coffee, which is easy to cause cardiovascular and cerebrovascular diseases, induce osteoporosis and cancer risk.
