With the development of China, children’s cheese has garnered increasing attention in the dairy industry, which has become a new growth point of China’s dairy industry. However, children’s cheeses currently available on the market are uneven, which cannot be fortified completely according to children’s nutritional needs. Their tastes are similar and their selling points are the same, which causes the public’s sensory fatigue and also go against consumers’ pursuit of clean label. Thus, the development of the children’s cheese industry is facing new challenges. In this paper, from the perspectives of children’s health and cheese nutrition, we link the needs of children of different ages for nutrition, flavor and texture with the nutrition, flavor and texture of cheese. The present situation, challenges and possible development directions of children’s cheese food in China are summarized.

Bile salt hydrolase (BSH) is considered to be especially relevant for microbes that reside in the mammalian gastrointestinal tract, which also helps to reduce the blood cholesterol level of the host. This review focuses on the occurrence of bile salt hydrolase among different microorganisms and its physiological characterization, enzyme activity, substrate specificity and genetics involved with recent updates. The current perspective reveals a huge market potential of probiotics with bile salt hydrolase.

The psychrophilic bacteria present in raw milk can grow under cold storage conditions and secrete protease and lipase which degrade milk protein and fat, resulting in the deterioration of milk quality. The present article summarizes the major species of psychrophilic bacteria in raw milk, with an emphasis on the recent progress that has been made in understanding the hazards of psychrophilic Bacillus including their species, hazard characteristics, proteases and lipases. At last, the future research direction of psychrotrophilic Bacillus is discussed.

Cronobacter spp. was originally defined as yellow-pigmented Enterobacter cloacae until 1980 when it was designated Enterobacter sakazakii, is a Gram-negative opportunistic food-borne pathogen that can cause necrotising enterocolitis, sepsis and meningitis in neonates. Neonates and infants under two months of age are at greater risk of Cronobacter infections from consuming Cronobacter spp. contaminated powdered infant formula. In 2012, the genus was reclassified to contain seven different species. Rapid and accurate identification of Cronobacter strains is important for surveillance, prevention and control of this food-borne pathogen. Moreover, this review summarizes main methods for detection and identification of Cronobacter spp., which will be of great benefit to the testing organizations in China.
