The invention discloses a Pickering emulsion with stable starch-myricetin composite nanoparticles and a preparation method of the Pickering emulsion, and belongs to the technical field of starch modification and emulsion delivery. Starch and myricetin are combined and compounded, a dynamic high-pressure microjet homogenization technology is introduced, the starch-myricetin composite nano-particles capable of stabilizing Pickering emulsion are obtained through a one-step method, and the application limitation that nano-starch is high in hydrophilicity, high in digestibility and the like is effectively solved; the prepared starch-myricetin composite nanoparticles have the characteristics of high stability and slow digestion function; the Pickering emulsion is prepared by further matching with a compound oil phase of coconut oil and cinnamon essential oil, so that the problem of coconut oil solidification can be effectively solved, and the Pickering emulsion has an antibacterial effect.

This invention discloses a method for preparing high-purity benzoic acid from cinnamon oil, belonging to the field of organic synthesis and natural product transformation technology. The steps are as follows: Cinnamon oil purification: Cinnamon oil is separated and purified using molecular distillation to obtain cinnamaldehyde with a purity ≥88.5%; The cinnamaldehyde obtained in step S1 is dissolved in an alkaline solution, a catalyst is added, and the mixture is heated under reflux. After the reaction is complete, a reaction solution containing benzoic acid is obtained; Product separation and purification: An organic solvent is added to the reaction solution for extraction, and the organic phase is distilled under reduced pressure to recover the solvent, yielding the final product benzoic acid. The organic reagents used in this method are all non-toxic and harmless or do not pollute the environment after decomposition. The reaction conditions are simple, the reaction is complete, and there are few or no byproducts, resulting in a high-purity final product.

This invention relates to the field of oral product technology, and in particular to a natural cola flavor base for oral products and its application. The flavor base of this invention is composed of sweet orange oil, lemon oil, white lemon oil, clove oil, cinnamon oil, and cassia oil. The method for determining the flavor base formulation includes: obtaining the content of each aroma component of a target cola flavoring and candidate natural flavorings; using the content of the key aroma component of the target flavoring as the dependent variable and the content of the corresponding component in the candidate natural flavorings as the independent variable, constructing a flavor base formulation prediction model to determine the proportion of natural flavorings added. This invention also provides oral products containing this flavor base and its preparation method. The natural cola flavor base of this invention uses all-natural ingredients and, through solvent-free design and elimination of easily discolored components, effectively improves the problems of easy discoloration, clumping, oil floating, and flavor instability in oral products during storage. The prepared oral products have excellent color stability, flavor harmony, and storage safety.

The present application relates to a kind of method for preparing high-purity natural cinnamyl aldehyde from cassia by combining rectification technology, comprising the following steps: step 1, cassia sample preparation;Step 2, cassia oil preparation;Step 3, install rectification device;Step 4, high-purity cinnamyl aldehyde preparation.The beneficial effects of the present application are: in the process of preparing high-purity cinnamyl aldehyde, most of the impurities are separated by the difference in boiling point through rectification column using rectification device, which greatly improves the purity of cinnamyl aldehyde, and the purity reaches 95.6%.
