The present application relates to the technical field of baked food, and particularly relates to an antioxidant baked composition and application thereof.The present application provides an antioxidant baked composition, which comprises an antioxidant composition and a baked ingredient; the antioxidant composition comprises the following components in parts by weight: 3-5 parts of chlamydomonas reinhardtii powder, 4-6 parts of tea tree flower powder and 3-5 parts of apocynum venetum tea powder.The chlamydomonas reinhardtii in the antioxidant composition of the present application contains algal polysaccharide and carotenoid, and provides high-quality protein and polyunsaturated fatty acid; the tea tree flower contains flavonoids and tea polysaccharide; the apocynum venetum tea contains flavonoid substances; the three raw materials are compounded in the present application, the active ingredients synergistically act, the antioxidant capacity is significantly improved, and the three raw materials synergistically enrich the nutritional composition (protein, dietary fiber and functional ingredients) of the product, realizing the dual values of "antioxidation + nutrition strengthening".

This invention relates to the field of aquaculture technology, and in particular to a biological attractant based on Schizochytrium fermentation broth and its preparation method; the biological attractant based on Schizochytrium fermentation broth is obtained by processing the fermentation broth after oil extraction from Schizochytrium; the fermentation broth after oil extraction from Schizochytrium is the residual fermentation broth after supercritical CO2 oil extraction or enzymatic hydrolysis oil extraction from Schizochytrium; the preparation method includes: pretreatment of fermentation broth, sterilization and stabilization treatment, concentration and regulation, and filling and storage; the three core components in the fermentation broth work synergistically, umami amino acids quickly trigger the taste perception of aquatic animals, algal polysaccharides slowly release odor molecules to prolong the feeding attraction time, and DHA enhances natural tropism, significantly improving the feeding induction rate of Litopenaeus vannamei, and maintaining a stable feeding attraction effect even in rainy and low-temperature environments; relying on the natural viscosity and structural characteristics of algal polysaccharides, there is no need to add stabilizers such as xanthan gum.

The invention relates to the field of degradable plastics, in particular to an antibacterial film, a preparation method and a freshness protection bag. The antibacterial film is of a layered structure and comprises a polymer layer and a coating layer, the one or two coating layers are positioned on one side or two sides of the polymer layer; the polymer layer is prepared by melting and mixing poly (butylene adipate-co-terephthalate), polylactic acid, polymethyl ethylene carbonate, an inorganic filler, a chain extender, a slipping agent and an antioxidant, and the coating layer is prepared from an algal polysaccharide solution, origanum essential oil and bamboo leaf essential oil; by preparing the raw materials of the specific coating layer, including the algal polysaccharide solution, the origanum vulgare essential oil and the bamboo leaf essential oil, the oxygen permeability of the prepared film is lower than that of an uncoated polymer layer and a PE film in the prior art, and the preservation time of food can be effectively prolonged.

The invention belongs to the field of aquatic product processing and preservation, and provides a shrimp meat water-retaining agent and application thereof, and the shrimp meat water-retaining agent comprises algal polysaccharides. According to the water-retaining agent, the edible red algae polysaccharide subjected to ultrasonic treatment is adopted as a main component, and compared with a common phosphate water-retaining agent, the water-retaining agent has better safety and environment-friendly characteristics on the basis of providing excellent water-retaining performance and texture feature keeping performance.

The application provides a detoxification and repair medical dressing for treating and relieving stubborn vulvar leukoplakia and a preparation method thereof, and relates to the technical field of gel dressings. The medical dressing is composed of a gel component and a composite antibacterial repair component, and the composite antibacterial repair component is composed of modified corn starch, anise camphene, eugenol, algal polysaccharide and Gynura japonica fermented inactivated extract. The Gynura japonica fermented inactivated extract is obtained by fermenting Gynura japonica with Bacillus subtilis and lactic acid bacteria and then inactivating. The application overcomes the shortcomings of the prior art, can effectively relieve itching during the treatment of vulvar leukoplakia under the premise of having an antibacterial effect, shortens the overall treatment cycle, and improves the comfort of treatment.
