Problems solved by technology

[0003]Although milk is good, not all people can enjoy it. Due to the lack of lactase, the human body cannot digest and absorb the nutrients in milk well, and will Causes absorption disorders of calcium, phosphorus, potassium, iron and other elements, affecting the physical and intellectual development of infants and young children. In the elderly, lactase deficiency is an important cause of osteoporosis

Abstract

The invention relates to a method for measuring galactose content using enzyme colorimetry and enzyme-linked method technology, the composition and components of reagents, the technical principle of which is based on the series of galactose kinase, pyruvate carboxylase and formate dehydrogenase After the catalytic reaction is completed, the present invention also relates to a galactose diagnosis / measurement kit. The assay method of the present invention has high sensitivity and small error, so the assay method and kit of the present invention can be widely used in clinical medicine / food inspection.

Description

【Technical field】 [0001] The invention relates to the technical field of medical / food inspection and determination, more specifically, the invention relates to a galactose diagnosis / measurement method and a kit thereof. 【Background technique】 [0002] Milk is known as "liquid gold" in the nutritional field. As early as 1992, seven departments in my country jointly proposed the slogan "a glass of milk strengthens a nation". Except for cellulose, milk contains almost all kinds of nutrients needed by the human body. After lactose in milk enters the human body, it is decomposed into glucose and galactose by the action of lactase in the small intestine. Galactose is an essential substance for the development of the baby's brain and is closely related to the rapid growth of the baby's brain. [0003] Although milk is good, not all people can enjoy it. Due to the lack of lactase, some people cannot digest and absorb the nutrients in milk well, and it will also cause absorption ob...
