Dry chemical reagent strip for detecting calcium, magnesium and zinc of breast milk

Abstract

The invention provides a dry chemical reagent strip for detecting calcium, magnesium and zinc of breast milk simultaneously. Specifically, the dry chemical reagent strip is composed of a supporting layer and a detection reagent block. The detection reagent block is whatman filter paper where a detection reagent for detecting calcium, magnesium or zinc is adsorbed, and the detection reagent block is directly pasted to one end of the long-strip-shaped supporting layer. When the dry chemical reagent strip is specifically used, the other end of the supporting layer is held by hand, the detection reagent block is completely soaked in a to-be-detected sample (breast milk) and then taken out, and after a color is stabilized, the color is compared with a standard colorimetric card. The dry chemical reagent strip can detect the content of calcium, magnesium and zinc simultaneously without mutual influence, and the sample is not polluted. The detection process is efficient and simple, and resultdata are reliable.

Description

technical field [0001] The invention relates to a technical field for rapid detection of calcium, magnesium and zinc, in particular to a detection reagent for breast milk calcium, magnesium and zinc and a dry chemical reagent strip for detection. Background technique [0002] Breast milk is the baby's natural nutrition. The composition of its milk directly affects the baby's growth and development, intellectual development and digestion ability, and it cannot be replaced by formula milk. The calcium, magnesium, and zinc content of breast milk nutrients are crucial to the growth and development of infants. Among them, calcium plays an important role in forming baby's bones and teeth, maintaining normal functions of nerves, blood, glands and heart. Zinc is an essential trace element for the human body. It is a component of various enzymes in the human body and has important physiological functions. It participates in protein synthesis in the body and promotes cell division, g...

Problems solved by technology

Among them, ultrasonic infrared spectroscopy and liquid biochemical reagent method have problems such as high equipment price, professional operation, long test time and cumbersome test process, while dry chemical reagent method has the advantages of rapid detection, low cost and simple operation. , flexible, less test samples, accurate test results, short test time, etc.

[0004] At present, foreign companies use dry chemical reagents to detect many products (such as German MN company, ARKRAY Co., Ltd., and American Johnson & Johnson Group Co., Ltd.), which have complex production processes, high requirements for materials and equipment, and samples need Pretreatment requires professionals to operate, etc.

[0005] In addition, U.S. Patent US5968833 discloses a dry chemical test paper for measuring magnesium concentration in biological fluids, Chinese Patent CN98109147.4 discloses a breast milk calcium eye test strip and Chinese Patent CN20120130424.0 discloses a dry chemical test paper for calcium determination. The methods in these patents of the experimental piece are qualitative or quantitative to detect one item alone, and the detection item is single, and it is impossible to detect multiple items at the same time

U.S. Patent US3511608 discloses a method for preparing a multi-parameter rapid detection card for dairy products. This method has a relatively cumbersome test process, and the test sample needs to be pretreated once during the test. After the pretreatment, the test can be carried out, and the required sample high volume problem

At present, there is no dry chemical reagent strip that can be used for rapid detection of calcium ions, magnesium ions and zinc ions in breast milk at the same time
