This invention belongs to the field of functional substance research, specifically relating to the use of casein hydrolyzed peptide compositions in improving aging, and more specifically to their use in the preparation of products for improving aging. The casein hydrolyzed peptide compositions are obtained by enzymatically hydrolyzing casein solution using serine protease and flavor protease. Furthermore, in the casein hydrolyzed peptide compositions, the relative strength of total functional peptides is above 25%, the relative strength of casein phosphopeptides is above 9%, and the relative strength of functional peptides other than casein phosphopeptides is above 11%. This casein hydrolyzed peptide composition can effectively alleviate oxidative stress caused by aging, inhibit chronic low-grade inflammation, reduce aging-related damage to vital organs such as the liver and brain, improve the body's immune function, and improve the external phenotype of aging, thereby comprehensively exerting an anti-aging effect.

The invention provides a dust suppressant for a coal mine strip mine tunnel and a use method of the dust suppressant, and relates to the technical field of mine dust prevention and control. The dust suppressant is prepared from the following raw materials in percentage by mass: 18-43% of a humectant, 0.04-0.3% of a surfactant, 0.1-0.3% of a crusting agent, 1% of a preservative and the balance of water, wherein the total mass of the raw materials is 100%. The additive amount of each component in the formula is clear, the production process is simple, a large amount of water supply equipment is not needed during construction, the method can directly adapt to the existing operation conditions of a mine field, and large-scale popularization is facilitated.
