The domestic silkworm microenvironment improving chemical agent is prepared from sodium percarbonate and calcium hydroxide; the raw materials are mixed to be uniform, and then the domestic silkworm microenvironment improving chemical agent is obtained. The domestic silkworm microenvironment improving chemical agent prepared from sodium percarbonate and calcium hydroxide can consume carbon dioxide generated by the organism and supplement oxygen, has a mulberry leaf preserving function, is beneficial for development of domestic silkworms and meets the young silkworm rearing requirements of the domestic silkworms.

The invention provides a carbon nanoparticle inhibitor and an application thereof, and belongs to the technical field of food processing. The carbon nanoparticle inhibitor comprises the following components and their weight proportions: 0.03-0.4 parts of tea polyphenols; 1-2 parts of gellan gum ; Sodium nitrite 0.008 to 0.05 parts. The carbon nanoparticle inhibitor of the invention can effectively inhibit harmful substances produced in high-temperature processed meat products, especially benzopyrene and carbon nano-particles produced during high-temperature processing of meat products, and is beneficial to human health.

The invention relates to a preparation for protecting activity of superoxide dismutase (SOD) and a preparation method of the preparation. The preparation for protecting the activity of the SOD contains the following raw materials: SOD, sodium hyaluronate, carbomer, glycerol, triethanolamine, imidazolidinyl urea, trehalose and deionized water. The preparation method comprises the steps: soaking the carbomer with water, sequentially adding trehalose and glycerol into the soak solution after soaking is completed, carrying out uniform stirring, and then, carrying out sterilization, so as to obtain a base solution; adding sodium hyaluronate into the SOD, carrying out uniform stirring, and carrying out filtration and sterilization, so as to obtain an SOD sodium hyaluronate solution for later use; sequentially adding the SOD sodium hyaluronate solution, triethanolamine and imidazolidinyl urea into the base solution under sterile conditions, then, adding the deionized water into the solution for adjusting, carrying out uniform mixing and stirring, carrying out sealing, and carrying out emulsification, thereby obtaining the preparation for protecting the activity of the SOD. The preparation and the preparation method thereof have the beneficial effects that all the raw materials of the preparation provided by the invention are combined together, so that the activity of the SOD can be effectively protected; the preparation cost is relatively low.

The invention discloses an electronic cigarette smoke solution solvent which comprises phytic acid, namely inositol hexaphosphoric acid. The phytic acid is independently used as the solvent of the electronic cigarette smoke solution, or is used as the solvent of the electronic cigarette smoke solution together with polyhydric alcohol, through the function of the phytic acid, the electronic cigarette smoke solution prepared by the electronic cigarette smoke solution solvent provided by the invention is thick and full in smoking experience and not oily, has no foreign flavor, is large in smoke amount, and has a relatively high smoking comfort level. The phytic acid is a nutriment beneficial to human bodies per se, and meanwhile has freshness retaining efficacy, so that the solvent not only can meet the sense requirement of a smoker, but also has the functions of nourishing, resisting aging and protecting mouth health.
