Nitrogen content detection method for infant formula milk powder

Abstract

The invention discloses a nitrogen content detection method for infant formula milk powder and belongs to the field of milk powder nitrogen detection. With the nitrogen content detection method for the infant formula milk powder of the invention adopted, a common user can remotely detect the infant formula milk powder through an Internet of Things technology; technical and theoretical thresholds for detecting the nitrogen content of the infant formula milk powder are avoided. According to the method, a user scans a commodity two-dimensional code on an infant formula milk powder subject througha mobile terminal to obtain the production batch information of the infant formula milk powder subject and uploads the corresponding production batch information to a cloud memory; the cloud memory uploads data to an Internet of Things module; and the Internet of Things module calls and summarizes the data; since data acquired by a milk factory detection processing terminal and a third-party laboratory detection processing terminal are summarized and sorted, so that the common user can clearly know the quality of milk powder to be purchased by the user, and irreversible damage to infants dueto the purchase of low-quality milk powder can be almost avoided.

Description

technical field [0001] The invention relates to the field of nitrogen content detection in milk powder, and more specifically relates to a method for detecting nitrogen content in infant formula milk powder. Background technique [0002] Milk powder is made from fresh milk or goat's milk, which is processed by freezing or heating to remove almost all the water in the milk, and adding appropriate amount of vitamins and minerals after drying. In order to meet different users, milk powder The corresponding nutritional elements will be added in the milk powder. The non-added nitrogen in the milk powder is mainly the protein in the milk powder, which is also the most nutritious component in the milk powder. Therefore, in a sense, the nitrogen content of the milk powder is directly related to the quality of the milk powder. Therefore, the nitrogen content of milk powder is an important indicator for milk powder detection. [0003] In the detection of infant formula milk powder, t...

Problems solved by technology

[0003] In the detection of infant formula milk powder, the most important thing is the detection of nitrogen content. The existing nitrogen content detection method is the Kjeldahl method, so in principle, the Kjeldahl method does not exist interfering nitrogen. However, the Kjeldahl method requires the use of strong acid and alkali and professional testing equipment in the testing process, and requires the testing personnel to have certain knowledge and skills in related fields. Therefore, in real life, it is difficult for ordinary users to detect the nitrogen content of milk powder by themselves when purchasing infant milk powder, that is, it is difficult to grasp the first-hand information of the quality of milk powder
