Problems solved by technology

Studies have shown that when the ratio of 11S globulin to 7S globulin increases, the hardness and gel viscosity of the gel formed by the protein will increase, and the emulsifying activity will decrease.

Embodiment 1

[0017] A kind of protein oral liquid that is conducive to zinc absorption, the preparation method is as follows:

[0018] To prepare a protein oral liquid that is conducive to zinc absorption: add 0.5%-15% β-lactoglobulin solution and 10%-15% 7S glycinin 1% zinc sulfate solution, then add α-lactalbumin with mass fraction of 20%-25% and 11S glycinin with mass fraction of 10%-15%, and continuously and slowly stir the reaction at 4 °C for 20 minutes to make the protein fully bind zinc ions. After that, 8 g of sucrose, 0.1 g of lactic acid, 0.05 g of rose essence, and 0.02 g of ethyl paraben were added, and purified water was added to make up 100 mL. Finally, a small amount of dilute sodium hydroxide solution was added dropwise to adjust the pH to 7.0, and the mixture was stirred continuously and slowly, sterilized, and filled into an 8 mL oral liquid bottle.

Embodiment 2

[0020] A protein oral liquid that is conducive to zinc absorption, the preparation method is the same as that of Example 1, the difference is: the mass ratio of β-lactoglobulin: 7S glycinin: zinc sulfate: α-lactalbumin: 11S glycinin is: (5%-7.5%): (5%-7.5%): (0.25%-0.5%): (10%-12.5%): (5%-7.5%).

Embodiment 3

[0022] A protein oral liquid that is conducive to zinc absorption, the preparation method is the same as that of Example 1, the difference is: the protein and zinc complex are continuously and slowly stirred for 30min at 4°C.

Abstract

The invention discloses a protein oral liquid beneficial to zinc absorption and a preparation method thereof. The method comprises the following steps: firstly, obtaining alpha-lactalbumin and beta-lactoglobulin in whey protein, and 7S glycinin and 11S glycinin in soy isolate protein; and secondly, firstly adding a zinc sulfate solution into a beta-lactoglobulin and 7S glycinin solution according to a certain mass fraction, then adding alpha-lactalbumin and a 11S glycinin solution, slowly stirring at 4 DEG C, adding cane sugar, lactic acid, rose essence and ethylparaben, and adding purified water to make up 100 mL. Dropwise adding a dilute sodium hydroxide solution to adjust the pH value to 7.0, slowly and uniformly stirring, sterilizing, and filling into a 8mL oral liquid bottle. The formula proportion and the adding sequence are provided, experiments prove that the zinc absorption efficiency is high, the problems that a conventional zinc supplementing agent is poor in absorption effect and has adverse effects are solved, and the zinc supplementing protein oral liquid is ideal.

Description

technical field [0001] The invention belongs to the technical field of food and health products, and particularly relates to a protein oral liquid that is beneficial to zinc absorption and a preparation method thereof. Background technique [0002] Zinc is an essential micronutrient for humans and plays an important role in structural stability, biocatalysis and signal regulation. Zinc deficiency can lead to serious diseases such as immune dysfunction, persistent diarrhea, chronic inflammation, and liver disease. Zinc deficiency is more severe in developing countries and is the leading cause of 4% of childhood morbidity and mortality worldwide. Since the body cannot produce zinc and has no specialized zinc reservoirs, the body must consume zinc from the diet on a daily basis to maintain zinc homeostasis at the cellular level. [0003] As people realize the importance of zinc, zinc supplements are also constantly developing and updating, mainly going through four stages: in...
