Problems solved by technology

[0008] The purpose of the present invention is to provide a low-oxalic-acid food, which retains most of the nutrients in the food while ensuring low-oxalic acid, in order to solve the problem that the existing methods for restricting dietary oxalic acid absorption are not effective and the technical difficulty is too high. The taste and senses are equivalent to the original food; another object of the present invention is to provide a technical method for preparing low oxalic acid food, which can remove oxalic acid in commonly used high oxalic acid food or drinks while retaining other nutrients and mouthfeel. Maintain a low oxalate state before eating, so that stone patients can also enjoy the happiness of a normal diet

Embodiment 1

[0031] Embodiment 1 low oxalate tea instant beverage

[0032] Take the green tea instant beverage as an example to illustrate the embodiment, select 1 kg of dry green tea, add 10 kg of deionized water after crushing, place it on an electric furnace, control the water temperature at 60-70 ° C for 30 minutes, filter through a filter cloth to remove slag, and add 0.2% tannin Enzyme, treated at 35°C for 2h, adding 0.3% (w / w) food grade CaCl 2 , (additional determination plus 0.3% (w / w) food grade MgCl 2 Treatment and the experimental group treated with weakly basic anion exchange resin) Stir to dissolve and mix well, let stand for 30min, heat to 60°C, dissolve the reversible precipitate for 10min, and centrifuge to remove the heat-insoluble oxalate precipitate in the extraction solution, while ensuring that the tea leaves Other active substances are not destroyed, and the filtrate is concentrated by reverse osmosis membrane, and the concentration pressure is 10kg / cm 2 , when the...

Embodiment 2

[0035] Example 2 Low oxalate soy milk

[0036] After 100g of soybeans are soaked and saturated with water, grind them into bean paste with 1kg of deionized water, adjust the pH value to 4.0 with citric acid, add 0.1g of oxalate decarboxylase (20000U / g), keep warm at 30°C and keep stirring, react for 30min, 60min , and 120min. After the reaction, the bean paste is separated and removed from the bean dregs to obtain soybean milk with a solid concentration of about 8%, immediately heated and boiled and maintained for 5 minutes, concentrated to a solid content of about 15% with a vacuum thin film evaporator, and finally dried by a spray dryer (inlet temperature 195° C., outlet temperature 80° C.) to obtain soybean flour. Soybean powder is made into instant soymilk powder products of different flavors and specifications through subsequent seasoning (such as adding soda powder to neutralize citric acid to ensure that the final product has a suitable taste and no unpleasant sour tas...

Embodiment 3

[0039] Example 3 Low Oxalate Buckwheat Bread

[0040] (1) Mix 300g of buckwheat flour, 700g of wheat flour, oxalate oxidase (1000U), 15g of white sugar, 30g of margarine, and 4g of salt according to a certain ratio and mix evenly. At the same time, no oxalate oxidase was set as a control, and the rest of the conditions were the same.

[0041](2) Then activate the yeast with an appropriate amount of water (warm water at 30°C for 20 minutes), and add it to the mixed flour.

[0042] (3) Use an appropriate amount of water to blend the flour into a dough. When the surface of the dough is not sticky, has strong elasticity and is uniform, it indicates that the dough has reached the best state, and the blending can be completed.

[0043] (4) Divide the dough into small noodle pieces of the same size, then knead them into rounds, make them into desired shapes according to requirements, and put them into an oiled baking tray, keeping proper intervals.

[0044] (4) Put the molded bread...

Abstract

The invention discloses a low-oxalic-acid food or beverage and a preparation method thereof. According to the low-oxalic-acid food or beverage, the raw materials are subjected to treatment of oxalic acid degrading enzyme, or treatment of positive ion salt precipitating oxalate in the food raw materials, or treatment of oxalic acid specific adsorbent resin absorption, or treatment by cells or tissues containing the oxalic acid degrading enzyme, or one or more of combined treatment in the method, and the food is prepared. According to the low-oxalic-acid food or beverage and the preparation method thereof, the oxalic acid in common high-oxalic-acid foods or beverages can be removed or reduced greatly, other nutritional ingredients and taste can be reserved simultaneously, and a gallstone patient can also enjoy normal diet happiness well.

Description

technical field [0001] The invention relates to the technical field of functional food and special medical formula diet, in particular to a low oxalic acid food or drink and a preparation method thereof. Background technique [0002] Urinary stone disease is a major health disease worldwide, and most urinary stones are composed of calcium oxalate or calcium oxalate and calcium phosphate. Patients with stones containing calcium oxalate account for more than 80% of patients with urinary stones. If maintenance and prevention are not paid attention to after recovery, they will usually recur in 2 to 3 years. The cumulative total recurrence rate reaches 50% in 5 years and exceeds 70% in 9 years. . [0003] Oxalic acid is a key factor leading to calcium oxalate stones, and its influence is 10 times higher than that of calcium ions. Oxalic acid is the final product in the human body, no longer participates in metabolism, and is mainly excreted in the form of urine. Hyperoxaluria ...
