Alkaline phosphatase test paper in milk

Alkaline phosphatase test paper in milk

Characteristics of qualitative testing paper: This type of qualitative testing paper has a wide variety and is used for rapid determination of ions and chemical components. It can determine whether a sample contains a certain amount of a substance.
Some of these qualitative test papers can be used for non-destructive testing of the tested substances.
Qualitative testing paper provides an economical and practical method for determining the presence of ions or compounds. If the concentration of the tested substance reaches a certain threshold, discoloration will occur.
Application of qualitative testing paper: inorganic chemistry, real-time environmental detection, special waste treatment, fire brigade, police, government, detection of peroxide residues after disinfection of dialyzers, etc.

Alkaline phosphatase test paper in milk

Milk is rich in minerals, fats, phospholipids, proteins, lactose, inorganic salts, as well as various nutrients such as calcium, phosphorus, iron, zinc, copper, etc. It is known as the "liquid gold" of food and has high nutritional value. However, there are also many pathogenic microorganisms in milk, so there will be a pasteurization process in the milk production process.

A suitable pasteurization process can kill pathogenic microorganisms in milk without damaging its nutrients. One standard for determining whether the pasteurization process is completed correctly is to detect alkaline phosphatase in milk.

For dairy production enterprises, the ideal testing process should be simple and easy to operate, and not time-consuming, ensuring that the hygiene and safety conditions meet the standards during production without affecting the timely completion of production tasks.

At present, there are many methods for detecting alkaline phosphatase in milk on the market, and the economical and simple method is to use test strips for detection. This alkaline phosphate test paper (product number 90612) from MN, Germany, can quickly determine whether the pasteurization process has been completed correctly by judging whether the test paper has changed color during use.

When measuring, simply place the test strip in milk for a while and then incubate at a constant temperature of 36 ℃ for about 1 hour. If alkaline phosphatase is present, the test block will turn yellow. Turning yellow indicates that there is still raw milk in the milk or that the milk has not been heated. If there is no change in color, it indicates that the pasteurization process has been completed correctly.

This product can detect raw milk with a mass percentage as low as 0.5% after pasteurization. The entire process is simple and easy to operate, and the detection results are intuitive and accurate. Therefore, alkaline phosphate test paper products are highly popular in the domestic dairy industry.
