Dairy products are favored by more and more consumers because of their rich nutrients and good taste, and have become an important part of consumers’ dietary structure. At the same time, the food safety of dairy products has become the focus of consumers’ attention. Therefore, controlling dairy food safety is a top priority for every dairy company. This article expounds on the food safety control measures for ensuring quality and safety in each link of the dairy product production process. To ensure the safety of milk sources, pasture construction and management and risk control during breeding activities need to be considered. The control of raw and auxiliary materials needs to be carried out by considering the acceptance system, storage of raw and auxiliary materials, and upstream supplier management and control. The control of the production process needs to be carried out from the aspects of personnel, equipment, ingredient and environmental management. In addition, this review highlights the importance of big data technology in dairy food safety risk analysis. We expect that this review will be helpful to relevant enterprises in improving their work on food safety management.

In this paper, an ion chromatography method for the determination of galactooligosaccharides (GOS) in milk powder was established. The protein in the sample was precipitated by acetonitrile, and GOS was extracted with acetonitrilewater and purified using a C18 column (or RP column) to remove impurities. The analyte was separated using an ion chromatograph equipped with quaternary gradient pumps and detected with a pulse amperometric detector. The calibration curve of this method had good linearity in the range of 10–300 μg/mL, and the results from repeated sample measurements were stable. The recovery rates from blank samples spiked at levels of 500–2 000 mg/100 g were 82.1%–98.0%. To sum up, this method required simple sample pretreatment and gave accurate results, and it could be suitable for the determination of the GOS content in milk powder samples.
