A color correction system and a method thereof are disclosed. A correction system according to the present invention includes an identification unit, a correction unit, and an adjustment module. The way of correction includes following steps: firstly the identification unit receives an image color data and identifies whether the image color data is a specific or a non-specific color data. Then the correction unit corrects the specific color data for display while the non-specific color data is adjusted by the adjustment module according to the color characteristics of the image output device. Therefore, the image data to be displayed is corrected and display quality of the image output device is improved.

The invention belongs to the field of stearic acid preparation, and in particular relates to a method for preparing 12-hydroxy stearic acid through utilizing hydrogenerated castor oil as a raw material. The method comprises steps of: utilizing the hydrogenerated castor oil as the raw material, saponifying, acidizing, washing, dehydrating and slicing to obtain a 12-hydroxy stearic acid product. The method is characterized by further comprising a decolorizing step after the washing step, wherein hydrogen peroxide is served as a decolorizing agent so as to complete a 12-hydroxy stearic acid decolorizing process. Compared with a conventional method, the method has an additional decolorizing step, the hydrogen peroxide is served as the decolorizing agent, other foreign ions are not introduced, and the generated product after final reaction is water which can be removed through dehydration, so that the product quality cannot be influenced; moreover, the decolorizing agent cannot damage the hydroxyl of the 12-hydroxy stearic acid.

The invention relates to edible mushroom composite nutrition tablets which are capable of improving mushroom taste and easy to absorb and utilize and a preparation method of the edible mushroom composite nutrition tablets. The edible mushroom composite nutrition tablets are prepared from the following raw materials in parts by weight: 10-30 parts of needle mushroom powder, 10-30 parts of hericium erinaceus powder, 10-30 parts of grifola frondosa powder, 20-28 parts of a hericium erinaceus raw sugar extract, 20-28 parts of a needle mushroom raw sugar extract, 40-60 parts of haw powder, 300-350 parts of a filler, and 8-15 parts of a lubricant. The edible mushroom composite nutrition tablets are prepared through the following steps of respectively performing third-stage dehydrating and drying on the needle mushroom powder, the hericium erinaceus powder and the grifola frondosa powder for crushing, decocting the hericium erinaceus raw sugar extract and the needle mushroom raw sugar extract which are used as raw materials with boiling water twice, and performing concentration. The nutrition tablets prepared by the preparation method disclosed by the invention are moderate in sour and sweet degrees in mouth feel, are rich in nutrition, have the effect of nourishing and protecting the stomach, and are easy to take and absorb, convenient to carry and simple in technology.

The invention provides an aroma-increasing additive used for a tobacco sheet as well as a preparation method and application thereof. The aroma-increasing additive used for the tobacco sheet is obtained by mixing Brazil tobacco leaf extract, Maillard reactant, tobacco powder and tobacco leaf fragment extract and propylene glycol, stirring and standing, wherein the Mailard reactant is obtained by carrying out reaction on purified water, glucose, praline, ammonia water with the concentration of 26% and caramel colour at specific temperature and under the regulation and has relative density of 1.1826 + / - 0.0080 (20 DEG C); and the tobacco powder and tobacco leaf fragment extract is obtained by extracting tobacco powder and tobacco leaf fragment with 50% ethanol, filtering, concentrating to the relative density of 1.3186 + / - 0.0080 (20 DEG C)and filtering again. When the aroma-increasing additive is added into coating liquid of the tobacco sheet, the problems that the tobacco sheet is dim in colour, aroma is missing and miscellaneous qi is strong can be effectively solved, aroma amount of tobacco in a suction process is increased, aroma texture is improved, and the miscellaneous qi is alleviated.

The invention belongs to the technical field of trace element production and particularly relates to a VB13 production method. The VB13 production method comprises the following steps that 1, urea, maleic anhydride and acetic acid are condensed; 2, the condensed material and bromine perform bromination reaction; 3, the brominated material performs acidification reaction with caustic soda liquid and hydrochloric acid; 4, the acidified material is crystallized; 5, the crystallized material is dried. The purity of VB13 produced by adopting the VB13 production method is above 98.5%, and the VB13 produced by means of the VB13 production method is a white crystal, the VB13 produced by adopting a traditional method is pink or light yellow, namely the color and luster appearance of the product is greatly improved. The VB13 production method is low in production cost. Compared with the prior art, the process cost of the VB13 production method is saved by 40%-45%.

The invention discloses a ginger processing method, which comprises the following steps: (1) cleaning: taking ginger raw materials, washing away silt, and removing impurities; (2) exhausting air: transferring the cleaned ginger to a steamer, Exhaust the air and water vapor in the steamer; (3) Airtight steaming: Steam the ginger in a sealed steamer at 100-130°C for 2-4 hours in the airtight steamer; (4) Stuffing: The airtight steaming is completed Finally, keep airtight stuffing, after making it cool naturally, open the steamer; (5) dry: dry the ginger after stuffing, and control the moisture between 6%-13%. Through the specific ginger processing method and process parameters of the present invention, the dissolution of beneficial ingredients in ginger is promoted, the content of total gingerol is increased, the transformation of gingerols into shogaols is promoted, and the total shogaols are increased. content, greatly increasing the content of water-soluble extracts and volatile oils, while protecting the fineness of the product, making the color and appearance of the product more excellent.

The invention discloses a method for preparing a 1-chlorine-2-(dichloro(benzene)methyl) benzene solution. As to an important precursor 1-chlorine-2-(dichloro(benzene)methyl) benzene required for manufacturing solid-phase synthetic resin of 2-chlorine trityl alcohol, reflux reaction on2-Chlorobenzophenone and excessive phosphorus pentachloride is carried out by adopting dichloroethane as a reaction solvent; then a reaction liquid is slowly put into an ice water mixture to hydrolyze and an organic phase is washed with running water for a plurality of times; an organic phase is obtained by dividing the liquid; and a drying agent is added to dewater, so as to obtain the 1-chlorine-2-(dichloro(benzene)methyl) benzene solution. The solution has very low byproduct content and is of light color; and the method is simple and efficient; and the solution can be directly used as the reaction liquid for producing 2-chlorine trityl alcohol resin. Therefore, the material is low in cost; and the resin product is good in color and luster and appearance, and good in swelling properties.
