It has the functions of antibiosis, diminishing inflammation, clearing away heat, eliminating phlegm, refreshment, etc.

The present invention discloses the composition of antioxidant of bamboo leaves (AOB) and its use. The purpose of present invention is to provide a new food additive which is natural, nutritional, and muti-functional, and which is of rich resources, safety, good effect, and low cost. AOB is yellow or brown powders or particles obtained from bamboo leaves, wherein the main antioxidative components include flavones, lactones, phenolic acids. AOB can either inhibit lipid autoxidation chain reaction, or chelate transitional metal ions, and can be used as primary and second antioxidant. AOB can eliminate nitrite and inhibit the synthesis of N-nitrosamine, and has anti-bacteria, bacteriostatic, deodorizing, aroma enhancing etc. functions. AOB can be commonly used in oil-containing food, meat product, fishery product, expanded food etc. food systems.

The invention discloses a method for reducing TSNAs in tobacco leaves of a cigar by utilizing strains. The method comprises the steps of: harvesting fresh tobacco leaves which are proper in maturity;drying the harvested fresh tobacco leaves in an air-drying shelter step by step, and in the drying process, inoculating in twice by bacterial solution with an OD600 value of 1, which is prepared fromat least one of strains 05-101, J45 and J54; and fermenting the air-dried tobacco leaves by adopting centralization stacking, and in the fermenting process, inoculating in twice by the bacterial solution with the OD600 value of 1, which is prepared from at least one of strains 05-101, J45 and J54 so as to obtain low-TSNAs cigar tobacco leaves. According to the invention, three strains capable of obviously reducing specific TSNAs in the cigar are selected, the single or mixed strains are fermented to prepare the bacterial solution and the bacterial solution is applied to the cigar air-drying and fermenting process, and temperature and humidity control in the air-drying and fermenting process is combined, so that high-efficiency directional degradation on the specific TSNAs in the cigar is implemented; and the method is good in stress resistance and simple and convenient to operate and has high popularization and application value.

The invention discloses a cigarette filter rod containing alginate fiber and a preparation method thereof. A core material of the cigarette filter rod is of the alginate fiber in the diameter of 0.5-4mm. The preparation method of the alginate fiber filter rod comprises the following steps: spinning the alginate fiber to single yarn through a traditional spinning process, and doubling to prepare an alginate fiber bundle; and drawing the alginate fiber bundle onto a forming machine through a drawing positioning device during the production process of the filter rod, adding to the central position of a filter tip through a filter tip forming device and further preparing the center line filter rod. The filter rod disclosed by the invention can effectively reduce harmful substances and components in smoke gas under the situation of keeping the release amount of tar oil and nicotine in the smoke gas of a cigarette unchanged basically, the removal rate of phenol can achieve about 39%, and the removal rate of nitrite amine can be about 28%. Simultaneously, on the premise of not changing the smoking style of the cigarette, the smoking quality of the cigarette can be improved by adding the alginate fiber into the filter rod.

The invention discloses a natural color retention material of soy sauce stewed duck products. The natural color retention material is obtained through performing extraction and filtration on a color retention powder material of soy sauce stewed duck products and water in an ultrasonic wave extraction machine, wherein the color retention powder material of soy sauce stewed duck products comprises safflowers, exocarpium citri rubrum, roses, cape jasmine flowers, Chinese wolfberry fruits, licorice roots, turmeric, fructus piperis longi, oregano, brassica juncea seeds, rhizoma polygonati, common sterculia seed, pungent litse fruits, citronella, cumin and calamus. The invention further discloses a preparation method of the natural color retention material of soy sauce stewed duck products and duck products made from the natural color retention material. The natural color retention material of soy sauce stewed duck products disclosed by the invention contains functional components of the safflowers and the like, pigment can gradually permeate into the soy sauce stewed duck products in the marinating process, and the soy sauce stewed duck products show comprehensive color of natural pigment. During marinating treatment, carbohydrate substances and amino acid substances in surface-layer duck meat generate a Maillard reaction, so that favorable soy sauce color of the soy sauce stewed duck products can be achieved, and the color is natural and not easy to change. Sodium nitrite is not used as a color former, so that nitrosamine carcinogens are not easy to produce.
