Instant powdery grease treating starch sodium octenylsuccinate as wall material, and its preparation method

The invention relates to an instant powdery grease treating starch sodium octenylsuccinate as a wall material. The instant powdery grease comprises 30-70% by mass of the wall material, 5-60% by mass of grease, 5-60% by mass of an auxiliary wall material, 0.5-3% by mass of an emulsifier, 0.1-2% by mass of an antioxidant and 0.1-0.5% by mass of a cosolvent. The invention also relates to a preparation method of the powdery grease. The preparation method is characterized in that a microencapsulation technology is adopted to embed fat-soluble grease in order to prepare a microcapsule, the wall material used for embedding is starch sodium octenylsuccinate, the addition of the emulsifier and the addition of the auxiliary wall material improve the emulsification shear speed, improve the homogenization pressure and increase the homogenization frequency, grease is embedded in the wall material and undergoes spray drying, and the addition of the cosolvent forms the instant powdery grease. The preparation method has the advantages of simplicity and low cost, and the prepared powdery grease has the advantages of good water solubility, fast dissolving, high oil carrying amount, and good fluidity and can be applied to the food field, the daily-use chemical engineering field, the medicine field and the like.

Bird driving composition and colloid mixture thereof, suspending agent and preparation method thereof

A driving-bird composite contains the following materials by different weight percentage: the driving-bird spice is selected from: 1 to 50 percent of methyl ortho-aminobenzoate, one or two of the 0.1-5 percent of heartleaf houttuynia herb essential oil or 10-21 percent of muskiness T; an antioxidant is selected from one or two of the 0.02-0.5 percent of 2, 6-BHT and sodium ascorbate, and the rest is control-released carriers. The driving-bird colloid mixture is made of the driving-bird composite, and the control-released carrier contains organic base or inorganic base, unsaturated fatty acid, antiseptic, emulsification, stabilizing agent, anti-freeze agent and the like. The driving-bird SC is made of the driving-bird composite, and the control-released carrier contains michael essien alkenyl succinic acid ester of starch sodium or Beta-cyclodextrin, antiseptic, emulsification, stabilizing agent, anti-freeze agent and the like. The invention utilizes the odor of the driving-bird spice for leading the bird-trigeminal to generate anaphylactic reaction and the bird-physiology to generate anorexia after pecking by means of diluting the sprayer, the driving-bird composite has the advantages of convenient usage and good effect of driving, and is harmless to the birds and the plant, thus belonging to the environment friendly biological agent products.

Emulsion gel embedding fat-soluble vitamins and production method based on pulsed electric field

The invention discloses an emulsion gel in which fat-soluble vitamins are embedded and a production method based on a pulse electric field. The production method includes the following steps: dissolving octenyl succinic acid modified starch in water, heating in a water bath, stirring until the material is completely gelatinized and dissolved, and cooling to room temperature; adding edible oil in which fat-soluble vitamins are dissolved to obtain a mixed solution; using a high-speed shearing machine and a high-pressure homogenizer to shear and homogenize the obtained mixed solution so as to a coarse emulsion; adding starch into the coarse emulsion, and uniformly stirring to obtain an emulsion; adding a methylcellulose solution to the emulsion, uniformly mixing and performing pulse electricfield treatment, heating in a water bath, degassing, and cooling to obtain an emulsion gel. The pulsed electric field of the invention promotes the interaction between methylcellulose and starch molecules, has a higher elastic modulus, and is easier to form a network structure that is more favorable for embedding fat-soluble vitamins. Thereby, fat-soluble vitamins are effectively embedded, and thepurpose of slowly releasing fat-soluble vitamins is achieved.

Method for preparing starch ester by recycling octenyl succinic anhydride

The invention discloses a method for utilizing octenyl succinic anhydride to produce starch ester in circulation. The method comprises steps that: water is added to 100 parts of dry basis starch; the starch is homogenized and emulsified; the pH value of the starch is regulated to 8 to 10; the starch is added to an octenyl succinic anhydride solution containing 3 parts of octenyl succinic anhydride, and is subject to a reaction; when the reaction is finished, the pH value of a reaction liquid is regulated to 5.5 to 6.5; the reaction liquid is filtered, and is processed from processes of washing, drying, crushing and sieving three times, such that white starch sodium octenyl succinate is obtained; a residual from the filtering process is mixed with the filtered washing solution, such that an octenyl succinic anhydride mixed solution is obtained; the solution is distilled, octenyl succinic anhydride is supplemented, and a solvent is added for dissolving, such that an octenyl succinic anhydride solution is obtained; water and ethanol obtained from distillation are fractionated, ethanol concentration is adjusted, and the materials can be repeatedly used. The method provided by the invention is advantaged in that: the technology is simple and is easy to control; recycling of octenyl succinic anhydride and recycling of the solvent can both be realized.

Amphipathic octenyl succinic short-straight chain starch nano-particles and preparation method thereof

The invention relates to preparation process of amphipathic octenyl succinic short-straight chain starch nano-particles. The preparation process comprises the following steps: (1) performing enzymolysis on gelatinized starch by using pullulanase, and obtaining short straight chain starch; (2) preparing a short straight chain starch solution, performing gelatinization, adding an octenyl succinic anhydride solution which accounts for 25-100% of the weight of dry powder of short straight chain starch, and continuously stirring for 6-10 hours, so as to obtain a modified octenyl succinic short straight chain starch solution; preparing a 1-10mg / mL solution of the octenyl succinic short-straight chain starch, stirring for 6-10 hours at 37-40 DEG C, and cooling to the room temperature, thereby obtaining a amphipathic octenyl succinic short-straight chain starch nano-particle solution. The particle size of the nano-particles is within 5-100nm, the nano-particles are good in tissue adhesion property, are capable of wrapping hydrophobic active substances, are high in loading rate and low in cost, the conveying efficiency of lyophobic active components by gastrointestinal tracts can be improved, and the bioavailability of the nano-particles can be improved. The lyophobic active components can be protected, the stability of the lyophobic active components can be improved, and the release of adverse flavor can be shielded; in addition, the addition amount and the toxic and side effects of bioactive components can be effectively reduced.
