Description

Ready-to-drink burdock bird's nest peptide liquid compound beverage easy to digest and preparation method thereof
Technical Field
The invention relates to the technical field of beverages, in particular to a ready-to-drink burdock bird's nest peptide liquid composite beverage easy to digest and a preparation method thereof, and belongs to the technical field of food processing.
Background
The burdock is a feverfew of Campanulales, has rich nutritive value, contains rich protein, amino acid, cellulose, vitamin and various mineral elements, and also contains special components such as inulin and chlorogenic acid; in addition, the burdock contains rich soluble fiber, which is the main component of burdock pharmacological activity, and has the effects of promoting development, promoting intestinal flora balance, inhibiting tumor growth, resisting bacteria, and the like. The burdock has high fiber content, and is easy to age if not preserved properly after being harvested and unearthed, so that the original taste and flavor are lost. Therefore, the quality loss caused by the sale process can be well avoided by developing the burdock product. The developed products of the burdock beverage are relatively few, the burdock tea is the most common burdock tea, and the dried burdock sliced tea has the problems of strong earthy taste, poor taste, inconvenience for drinking after being soaked in boiling water and the like. The other types of burdock beverages and burdock fermented beverages are basically prepared by simply boiling and extracting burdock with water and mixing the burdock with red dates, longan, milk, Chinese herbal medicine raw materials and the like, and the burdock beverages have the problems that the flavor of fresh burdock is basically covered, the carbohydrate content is too high, the digestion rate is low, the nutrient content is single and the burdock fermented beverage is difficult to absorb and the like.
The edible bird's nest mainly comprises water, ash, fat, protein and saccharide, and comprises five kinds of semi-essential amino acids and six kinds of essential amino acids. The carbohydrate and protein in the cubilose usually exist in a form of combined glycoprotein, the cubilose mainly contains five monosaccharides or monosaccharide derivatives, wherein N-acetyl neuraminic acid (sialic acid) is a monosaccharide conversion product, the sialic acid can promote and improve the nervous system and the immune system of a human body after being absorbed by the human body, and the content of the sialic acid accounts for about 10 percent of the cubilose, which is difficult to achieve in other purely natural foods. The protein in the cubilose is subjected to soaking and stewing, and a large amount of insoluble protein exists. After simulating gastrointestinal tract digestion, protein fragment electrophoresis analysis shows that the digested supernatant has over 50% of high molecular protein incapable of being degraded. This indicates that although the protein content in the edible bird's nest is high, some protein can not be absorbed by human body, which causes great waste to the edible bird's nest which is a precious food raw material. Although the literature has already carried out research reports in this respect, most of the existing research aims at extracting and purifying certain specific components of the cubilose and then applying the components, but does not reserve the full-spectrum nutritional components in the cubilose; in addition, the preparation method of the bird's nest related products also has the problems of excessive treatment steps, high probability of microbial contamination, higher equipment requirement, high energy consumption, obviously lower enzyme dosage, too wide enzyme variety, incapability of effectively degrading proteins and the like.
At present, a plurality of relevant documents about burdock beverages or cubilose products are reported, but no beverage prepared by compounding burdock and cubilose is reported.

And (3) carrying out a digestion simulation experiment on the composite beverage, and detecting the change condition of 7 indexes, namely the total sugar content, the sialic acid content, the protein content, the polypeptide content, the amino acid content, the chlorogenic acid content and the soluble solid content in the sample before and after digestion by using the composite beverage prepared in the first embodiment.
1. Test method
(1) Simulated gastric fluid digestion experiment steps: taking 250mL of beverage in a conical flask, adjusting the pH value of the sample to 1.3 by using 1mol/L HCl after the beverage is put in a water bath at 37 ℃, adding 250mL of simulated gastric juice, digesting the sample in a constant-temperature water bath at 37 ℃ for 1h in a dark condition, and putting the sample in a water bath at 70 ℃ for 5min to inactivate after the digestion is finished.
(2) Simulating intestinal juice digestion experiment steps: 250mL of a sample after simulated gastric digestion was taken, adjusted to pH 6.8 with 1mol/L sodium hydroxide, and 250mL of intestinal fluid was added. Continuously placing in a 37 deg.C water bath for 3 hr under dark condition, placing the sample in 70 deg.C water bath for 5min, cooling, centrifuging at 10000r/min for 6min, and collecting supernatant for determination.
2. Test results
The simulated changes of total sugar, sialic acid and soluble solid before and after digestion are respectively shown in figure 1, figure 2 and figure 3, and the simulated changes of protein, polypeptide, amino acid and chlorogenic acid before and after digestion are shown in figure 4. The results in the figure show a significant decrease in sialic acid and a significant increase in amino acid content. Amino acids, which are the smallest amino group-containing unit in the living body, are directly absorbed by the human body. All components except the polysaccharide are degraded to different degrees, so that the content of small molecular components such as amino acid and the like is increased, and the components are easier to digest and absorb. Although the polysaccharide is not obviously degraded, the research results show that the macromolecular structure of the components has obvious correlation with the immunity improvement of human bodies and has special effects except nutrition.
