Embodiment 1

[0010] A detection method for the vitamin C content in fruits. Take the fruit to be tested and weigh it, add freshly boiled cold water and sulfuric acid solution to dissolve it, add starch indicator solution, and immediately titrate with iodine titration solution until the solution turns blue and disappears at 30 It does not fade within seconds. Use the titration method to detect the content of vitamin C in various fruits, and divide the fruits into three categories according to the content: high Vc content, medium Vc content, and low Vc content. Analyze the growth environment of various fruits, and vitamin C activity.

Abstract

The invention relates to a method for detecting the content of vitamin C in fruits, which comprises the following steps: detecting the content of the vitamin C in various fruits by titration; dividingthe fruits into three classes according to the content; and analyzing the growing environment of each class of fruits and the activity state of the vitamin C. Compared with the prior art, the methodfor detecting the content of the vitamin C in the fruits has the characteristics of simplicity, convenience, low price and the like.

Description

technical field [0001] The invention relates to vitamin C, in particular to a method for detecting vitamin C content in fruits. Background technique [0002] Vitamin C plays an important role in the formation of collagen. Collagen is an important substance for the development and repair of human tissue cells, gums, blood vessels, bones, and teeth. It helps the body absorb iron. It is often recommended as a substance for preventing sudden infant death syndrome (SIDS). Smokers and the elderly need it More Vitamin C. (A cigarette can destroy 25-100mg of vitamin C). The effect is to treat injuries, burns, bleeding gums, enhance the efficacy of drugs for urinary tract infections, accelerate recovery after surgery, help lower blood cholesterol, prevent viral and bacterial infections, and enhance the immune system. Cancer effect, helps to prevent the formation of nitrosoamines (carcinogens), can be used as a natural laxative, reduces the occurrence of blood clots in veins, can t...
