Natural calcium alginate chitosan three-layered microemulsion compound coating preservative and preparation method and application thereof

The invention relates to a natural calcium alginate chitosan three-layered microemulsion compound coating preservative and a preparation method and application thereof. The preservative is prepared from the following substances: sodium alginate, natural antioxidant and antibacterial substances, glycerol, sodium chloride, chitosan, tripolyphosphate and water. The preparation method comprises the following steps: crosslinking a sodium solution where non-toxic pure natural antioxidant and antibacterial substances are dissolved with calcium chloride to form a calcium alginate double-layered microemulsion where the natural antioxidant and antibacterial substances are embedded; adding a tripolyphosphate solution after the microemulsion and the chitosan solution are compounded; and uniformly mixing the solution and ultrasonically crushing the solution to prepare the calcium alginate chitosan three-layered microemulsion compound coating preservative. By taking sodium alginate and chitosan as acarrier, the preservative has a relatively good film forming property on the surface of a meat product and generates antibacterial and antioxidant synergic effects by pure natural plant extract, andthe three-layered emulsion can control the slow release rate of the natural plant extract well. As the preservative is applied to products of stewed ducks in soy sauce and stewed chicken in soy sauce,the shelf lives of the products are prolonged greatly.

Effective mapping of code sections to the same section of secondary memory to improve the security of computing systems

Executable computer code sections can be stored in the same section of secondary memory (e.g., instruction cache) during execution time in order to reduce the observable changes to the state of the secondary memory, thereby enhancing the security of computing systems that use secondary memory in addition the primary (main) memory to support execution of computer code. In addition, size of code sections can also be effectively adjusted so that code sections that are mapped to the same section of the secondary memory appear to have the same size, thereby further reducing the observable changes to the state of the secondary memory. As a result, the security of computing system can be further enhanced. It should be noted that code sections can be effectively relocated to cause them to map to the same section of secondary memory. It will be appreciated that mapping code sections considered to be critical to security can be especially useful to improving security. For example, codes sections considered to be critical to security can be identified and effectively mapped to the same section of an instruction cache (I-cache) as provided in more modern computing systems in order to improve the efficiency of execution, thereby allowing use of the I-cache in a more secure manner.
