Application of methyl ferulic acid

    Methyl feruate is also called methyl 4-hydroxy-3-methoxycinnamate.Methyl ferulic acid, 99% effective component, is a white crystalline powder, with antioxidant, whitening, anti-inflammatory and other effects.It can be used in cosmetics, so that the skin has a silk texture, can prevent or delay the oxidation and deterioration of food ingredients.Methyl feruate can be divided into oil soluble and water soluble antioxidants according to its solubility.By source can be divided into natural and synthetic two categories.Methyl feruate can prevent or delay the oxidation of food, but not after food oxidation.Therefore, methyl feruate must be added before oxidative deterioration.The amount of antioxidants is generally small (0.0025% -0.1%), but it must be fully mixed with food to play a good role.In addition, citric acid, tartaric acid, phosphoric acid and its derivatives all have a synergistic effect with antioxidants, and play the effect of synergistic agent.

    I. To determine the anaerobic fungal ferutesterase activity
    In the feed industry, the use of ferutesterase processing plant raw materials, can free ferulic acid from the plant cell wall structure, thus destroy the cell wall skeleton structure, make the connection between lignin, hemicellulose and cellulose is partially broken, the structure becomes loose than before treatment, become loose raw materials is easier to be absorbed by livestock, can improve the utilization efficiency of feed.It can be seen that ferutesterase has broad application prospects.At present, the ferutesterase-producing microorganisms found are mainly Aspergillus niger, Streptomyces, Clostridium, Bacilli, Lactobacillus, Pseudomonas, etc.But the vast majority of feruliate esterases were isolated from aerobic bacteria and fungi.Studies have shown that anaerobic fungi are also able to secrete ferutease, and ferutease activity is relatively high.
    CN201310232422.7 provides an optimized method for ferutesterase activity measurement suitable for anaerobic fungi.Include the following steps:
    Preheat the enzyme solution and phosphate buffer solution, and then add the substrate methyl feruate to the enzyme solution, heat up the reaction, detect the absorption value of the reaction at 0min and 30min, and calculate the ferutease activity, the pH of the feruate buffer solution is 8.0 and the temperature of the preheat and reaction is 40℃.

    Two, for the preparation of an ozone-resistant communication optical cable sheath special material
    At present, the materials used in communication optical cable sheath on the market have the disadvantages of poor ozone aging resistance, long-term ozone pollution will appear the aging of the sheath, easy to crack phenomenon, seriously affect the transmission of optical fiber.CN201410595901.X provides a special material for ozone-resistant communication optical cable sheath and its preparation method.
    To achieve the above purpose, The technical scheme adopted in the present invention is as follows: a special material for ozone-resistant communication optical cable casing, Made from the following weights: chlorsulfinated polyethylene 52-66, hydrogenated nitrile rubber 34-48, talc 10-15, acrylonitrile-chloride polystyrene-styrene copolymer 22-33, dibutyl dithiocaramate nickel 1-2, N- (4-aniline phenyl) maleimide 2-3, alkalkyl sulfonylate 5-10, melamine 3-6,1, 3-Diethyl-1, 3-Diphenyllurea 2-3, silica aluminum carbon black 15-20, zinc carbonate 4-8, triacrylate cyanocyanate 3-5, epoxy soybean oil 10-15, sand wax 4-6, methyl ferulate 3-5, boron phosphate 5-8, N-nitrodiamenediamine 2-3, dibenzoyl quinone dioxime 1.5-2.5, additives 2.5-4.5;
    The aid shall be prepared as follows:
    A. Take calcium zirconate 10-15, methyl (2,4-di-butyl) aluminum phosphate 3-5, titanium oxalate 2.5-4.5, leto 8-12,3,5-di-4-2-3, dodecyl glucosamine 1-2, N-aminoethyl piperazine 0.5-1.5, diisobutyl fumarate 5-10, sucrose benzoate 4-8, tertiary pentadiol 2-4, coconut oil dihydroxyoxyloxidide 1-2;
    Take b, calcium irate and totorite mixed evenly, crushed, 150-200 mesh screen, then add aluminum phosphate, titanium oxalate, lamine, coconut oil, 800-1000rpm high speed mixing for 4-6min, diisobutyl fumarate, sucrose benzoate, penta, 3,5-di-butyl-4-hydroxybenzoate, N-piperzine, 1000-1500rpm high-speed mixing for 3-5min, namely.
    The present invention has high ozone resistance, excellent aging resistance, high mechanical strength, excellent acid and alkali corrosion resistance, oil resistance, heat resistance and wear resistance, prolong the service life of the sheath, suitable for special places with high ozone resistance requirements.
