Infant formula has widely used as infant food besides human milk. The aroma characteristics determine the sensory quality of this product and the purchase intention of consumers to a great extent. It was generally developed infant formula products into 1-stage (for babies at 0~6 months), 2-stage (6~12 months) and 3-stage (12~24 months). In this study, a combination of quantitative description analysis (QDA), gas chromatography olfactory mass spectrometry (GC-O-MS) and gas chromatography high-resolution mass spectrometry (GC-Orbitrap-MS) was used to study the aroma characteristics and the aroma compounds composition in infant formulas with three different stages. The results showed that, there were significant differences in the aroma profiles of different stages of milk powder. There was a significant difference (P

With the advent of aging society, the skeletal muscle volume and muscle strength of the elderly are reduced, and they are prone to sarcopenia. Sarcopenia has caused a lot of inconvenience to the life of the elderly. At present, the symptomatic medical treatment for sarcopenia is not perfect. It is necessary to understand its pathogenesis and treatment measures. Protein supplementation, as the most healthy, effective and convenient method, has attracted people's attention. This paper summarizes the pathogenesis and current prevention and treatment methods of sarcopenia, the significance of protein action and sarcopenia and the role of protein in the prevention and treatment of sarcopenia are clarified. It lays a theoretical foundation for the application of protein in different ways and the treatment of sarcopenia.

Osteoporosis is a systemic bone disease characterized by decreased bone mass, osteopenia, and bone microstructure degradation. The cause is that the activity of osteoclasts is greater than that of osteoblasts, resulting in bone resorption greater than bone formation. The current method of treating osteoporosis is mainly through calcium supplementation or drug treatment, but it would be accompanied by disadvantages such as poor absorption, insignificant effect, and large side effects. Plant natural active ingredients have the characteristics of wide sources, abundant structure and less adverse reactions. They could be used as new methods to prevent and treat osteoporosis. This article summarizes the anti-osteoporosis effects of osteoporosis and plant active ingredients. Through the analysis of related signal pathways, transcription factors, protein expression and other aspects, the anti-osteoporosis mechanism of plant active ingredients and related clinical research are described. On this basis, the anti-osteoporosis products of medicinal and edible plants are introduced, aiming to provide theoretical support for the development of new drugs and functional foods.
