Description

Technical Field

[0001] This invention belongs to the field of drinking water processing technology, specifically relating to a method for preparing functional drinking water based on a pH-responsive microcapsule sustained-release system. Background Technology

[0002] Drinking water refers to water that can be supplied directly to the human body without treatment. Water is a major component of body fluids and an important substance that constitutes cells, tissue fluid, blood plasma, etc. Water serves as the medium for all chemical reactions in the body and is a platform for the transport of various nutrients and substances.

[0003] Traditional drinking water is typically disinfected by water plants using chlorine or chlorine-containing compounds to kill bacteria and viruses in the water. This is a crucial step in ensuring the safety of drinking water microorganisms. However, chlorine reacts with natural organic matter in the water (such as decaying plants) to produce disinfection byproducts such as trihalomethanes and haloacetic acids. These byproducts have a poor taste and, with long-term consumption, may lead to the repeated intake of certain elements, resulting in nutritional imbalances. Summary of the Invention

[0004] The purpose of this invention is to provide a method for preparing functional drinking water based on a pH-responsive microcapsule sustained-release system in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: This invention provides a method for preparing functional drinking water based on a pH-responsive microcapsule sustained-release system, comprising the following steps: Step S1, base water treatment: raw water is filtered through sand, activated carbon adsorption and ultraviolet sterilization to obtain base water; Step S2, preparation of hydrolyzed protein peptide melt: Dissolve the hydrolyzed protein peptide in 40°C warm water and stir until completely dissolved; Step S3, preparation of transparent gel: Mix base water with sodium hyaluronate and stir for 2 hours to obtain transparent gel; Step S4, Preparation of Vitamin C + Acerola Cherry Powder Mixture: Mix Vitamin C and acerola cherry powder under light-protected conditions until homogeneous to obtain a mixture; Step S5, Preparation of zinc lactate aqueous solution: Mix base water with zinc lactate, and after homogenization, filter through a 0.45μm filter membrane to obtain zinc lactate aqueous solution; Step S6, Preparation of nicotinic acid microcapsule solution: Mix base water with nicotinic acid microcapsules, and after uniform mixing, filter through a 0.45μm filter membrane to obtain nicotinic acid microcapsule solution; Step S8, preparation of functional drinking water: Add base water, hydrolyzed protein peptide melt, and transparent gel to the mixing tank in sequence, and stir at 160-200 rpm for 35 min; add vitamin C + acerola cherry powder mixture, zinc lactate aqueous solution and niacin microcapsule liquid in sequence, and disperse evenly through a homogenizer to obtain functional drinking water.

[0006] As a further optimization of the present invention, the method for preparing functional drinking water also includes sterilization and bottling: Step S1, Low-temperature sterilization: Sterilization treatment is carried out at 5℃; Step S2, Aseptic filling: Fill into PETG bottles in a Class 100 clean environment and then fill with nitrogen for preservation; Step S3, secondary sterilization: pasteurize at 72℃ for 15 seconds.

[0007] As a further optimization of the present invention, the sterilization treatment adopts 0.22μm membrane filtration or ultraviolet instantaneous sterilization.

[0008] As a further optimization of the present invention, the functional drinking water also includes citric acid, which is added dropwise after being evenly dispersed in a homogenizer, stirred evenly, and adjusted to a pH value of 3.5-4.0.

[0009] As a further optimization of the present invention, the raw water is either tap water or spring water; the conductivity of the base water is ≤10μS / cm.

[0012] As a further optimization of the present invention, the preparation materials of the functional drinking water, by weight, include: 50-65 parts base water, 3-6 parts hydrolyzed protein peptide melt, 5-12 parts transparent gel, 5-10 parts vitamin C + acerola cherry powder mixture, 1-3 parts zinc lactate aqueous solution and 6-12 parts niacin microcapsule liquid.

[0013] A functional drinking water based on the pH-responsive microcapsule sustained-release system described above is prepared by the above method.

[0014] The beneficial effects of this invention are as follows: The functional drinking water prepared by this invention, through the addition of natural plant extracts and trace elements, can improve physical fitness endogenously, promote blood circulation, increase the antioxidant capacity of the drinker, and help enhance physical vitality and immunity by oral supplementation.

(two) The performance of the functional drinking water prepared according to the methods of Examples 1-3 and Comparative Examples 1-2, and the blank group (ordinary purified water) were tested using the following experimental methods: Experimental conditions: 1. Twelve-week-old C57BL / 6 mice were divided into 6 groups, with 20 mice in each group; 2. Mice were fed a high-fat rat diet of type D12492 (60% fat for energy) at regular intervals and in fixed quantities. Their drinking water was prepared using the methods of Examples 1-3 and Comparative Examples 1-2, respectively, and the blank group (ordinary purified water). 3.
