Rapid Determination of Formaldehyde in Food

Formaldehyde is a highly toxic, protoplasmic substance that destroys biological cell proteins and can cause allergies, intestinal irritation, and food poisoning. In food production, processing and transportation, it is generally not easily contaminated by formaldehyde. The trace amount of formaldehyde in certain food backgrounds is not enough to cause harm to human body, such as: barley flour about 24mg/kg, wheat flour 2~14mg/kg, mung bean powder about 2mg/kg, cotton sugar 4~7mg/kg, Baisha sugar 1~4 mg/kg, red pond 1~3 mg/kg, bean curd 4~6 mg/kg, fans about 1 mg/kg, carp meat 13~48 mg/kg. Some other seafood products often have several mg/kg or even tens of mg/kg of formaldehyde present in the meat.

Because formaldehyde can change the color and antiseptic properties of some foods, driven by ignorance or pecuniary interests, illegal elements in some areas add formaldehyde to certain foods. This method is mainly directed at the detection of formaldehyde in water in water products. Even if the water-soluble product itself contains dozens of mg/kg of formaldehyde, its dissolution in water is of the order of ug (ppb). This method is not easy to observe. When humans add more than 10mg/kg of formaldehyde (this content Only a slight antiseptic effect can be detected quickly. 1. There are two reagents in the indicator preparation kit. After the big reagent is dissolved in 80 ml of distilled water or purified water, the reagent in the small reagent tube is added to dissolve it, and diluted with water to 100 ml, and put into a brown bottle or wrapped. The black paper bottle is ready for use. The expiration date is 3 months. After the indicator is placed, it will be stratified. Before use, it must be gently shaken more than 20 times. (The indicator is strongly alkaline, if it accidentally splashes into the eyes, rinse with water). 2. Measurement method Take 5 to 10 ml of water soaked product in a colorimetric tube, add 1 ml of formaldehyde indicator, and observe results within 1 minute after shaking. 3. Results Determination and Precautions If the sample solution contains 20mg/kg of formaldehyde, the solution will immediately turn orange-red, after a few minutes the color fades, the higher the concentration, the darker the color, until the deep red, and the color is not easy to recede .
