How do you know that shed sand is added to food?

Because borax can increase the toughness and crispness of food, improve the water retention and preservation of food, the meat products added with borax are fluffy and elastic, which can save time and cost to a great extent and achieve satisfactory sensory properties and taste, and are deeply loved by small workshops.

The detection method of borax pollution in food is as follows:

(1) Sensory test: All foods added with borax are smooth to the touch and can smell slightly alkaline.

(2)pH test paper method: Stick a pH test paper on rice sausage, cold bran and other foods. If the pH test paper turns blue, it proves that the food is contaminated by borax or other alkaline substances. If the test paper does not change, it means it is normal.

(3) Test method for the characteristics of turmeric test paper: firstly, the turmeric root is ground into powder, washed with clear water for several times, then soaked in 6 times of Chinese liquor, and insoluble substances are filtered to obtain turmeric liquid. Then cut the fast filter paper into small strips, soak it in turmeric solution, and put it in a sunny place to dry for later use. When testing, put the turmeric test paper on the surface of food such as vermicelli, cool it to brown and wet it, and then immerse the test paper in alkaline water. If the test paper is light blue, it proves that food such as vermicelli and cold brown is contaminated by borax. If the test paper is brown, it is normal.
