Abstract
The invention belongs to the field of gelatin preparation, and particularly relates to a method for quickly preparing special gelatin for candies from raw bone meal. The method comprises the following process steps of: meal milling, impurity removal through pickling, water washing, gelatin solution extraction, neutralization, rough filtration, fine filtration, and packaging after concentration and drying. According to the method, animal bones are milled into bone meal to increase the specific surface area of the bone meal and increase the reaction speed of the bone meal; and compared with the traditional gelatin production, the method disclosed by the invention has the advantages that: the production cycle is shortened by more than 60 days, and pollution and consumption are reduced. The gelatin prepared by using the method has the advantages of high freezing intensity, moderate viscosity, good transparency and low cost; and the viscosity of the gelatin is matched with the freezing intensity of the gelatin, so that the gelatin is suitable for the field of producing foods such as candies and the like.
Description
One, technical field:
The invention belongs to the gelatin preparation field, particularly a kind of raw bone meal prepares the method for the special-purpose gelatin of candy fast.
Two, background technology
Traditional alkali process is all adopted in China's bone gelatin(e) production at present, and its operational path is: animal bone → skeletal grain → pickling → washing → liming → wash → neutralize → wash → carry glue → filtration → concentrated → drying → pulverizing.Though having, the tradition gelatin goes up century-old history, the technology comparative maturity, and the production cycle is long; Reach 60 days to 90 days, the consumption of various materials is high, and especially water resource waste is serious; What the traditional technology liming was adopted is milk of lime, all has every day a large amount of lime-ash, waste water to produce, and belongs to highly energy-consuming, high pollution industry; And its gelatin product is applied in the candy industry when the time existing viscosity to meet optimality criterion 3.7-4.3mpa.s, the intensity of congealing 120-180g on the low side; And the intensity of congealing is when meeting optimality criterion >=240g, the higher 4.6-5.2mpa.s of viscosity because the viscosity of gelatin do not match with the intensity of congealing, be applied in confectionary products after, be prone to adhesion, influence moulding, can not satisfy the requirement of confectionary products.The patent of invention of publication number CN1977013A discloses the method for a kind of preparation and purifying gelatin, and this method is that the animal bone water is worn into slurry, and the high temperature extracting obtains glue in the acidic solution of PH=2.4-3.9; Again through separating for several times, concentrate, drying obtains gelatin product, this method is processed pulp with the water mill aggregate, water consumption is big; The industrialization difficulty is big; This method is handled without pickling and is sloughed the mineral substance in the aggregate, but directly in acid solution, extracts glue, will have a large amount of impurity in the glue and be difficult to separate; Influence the purity and the performance of gelatin, can not satisfy the requirement of confectionary products.In recent years, have the report enzymolysis process to prepare the method for gelatin, its production cycle shortens, but cost is high, does not appear in the newspapers to be used for confectionery industry.
Three, summary of the invention
The present invention is directed to present manufacturing of gelatin industry and do not have special-purpose gelatin of the confectionery industry of being exclusively used in and the present situation that other gelatin can not satisfy the confectionery industry requirement fully; The just viscosity of gelatin and the unmatched problem of intensity of congealing; The method that a kind of raw bone meal prepares the special-purpose gelatin of candy has fast been proposed; The technical scheme that the present invention takes is: a kind of raw bone meal prepares the method for the special-purpose gelatin of candy fast, it is characterized in that it and is made up of following operation: animal bone abrasive dust → pickling removal of impurities → washing → extracting glue → neutralization → coarse filtration → essence filter → concentrate drying packing; Wherein: the processing condition of animal bone abrasive dust operation are: animal bone is ground to form 40～160 purpose raw bone meals; The processing condition of pickling removal of impurities operation are: will grind good raw bone meal and in temperature is 15 ℃～25 ℃ acid solution, soak 6～12 hours; Slough the impurity such as mineral substance in the raw bone meal; The pH value of acid solution is 1～2.5, and the mass volume ratio of raw bone meal and acid solution is 1g:2～6ml; The processing condition of washing step are: the raw bone meal behind acid soak is used water washing, to the PH=4 that washes water～6; The processing condition of extracting glue operation are: the raw bone meal after will washing in temperature be under 40 ℃～70 ℃ the alkali lye through 5～18 hours extracting glues, the pH value of alkali lye is 8～14, the mass volume ratio of raw bone meal and alkali lye is 1g:4～10ml; In with the processing condition of operation be: the extracting glue is regulated pH value to 5.5～6.5 with acid; The processing condition of coarse filtration operation are: the extracting glue of becoming reconciled in inciting somebody to action with filter filters under 40 ℃～60 ℃ temperature, and gelatin solution is separated with solid residue; The processing condition of smart filter operation are: with the smart filter under 40 ℃～60 ℃ temperature of the gelatin solution after the coarse filtration; The processing condition of concentrate drying packaging process are: essence filtrating is packed with the ordinary method concentrate drying.Wherein acid solution is hydrochloric acid solution or nitric acid or phosphoric acid liquid or Glacial acetic acid min. 99.5 liquid.Alkali lye is the complex liquid of two kinds of alkali lye of Pottasium Hydroxide alkali lye or sodium hydroxide lye or yellow soda ash alkali lye or sodium hydrogencarbonate alkali lye or calcium hydroxide alkali lye or above-mentioned alkali lye.Coarse filtration adopts vacuum filtration and Plate Filtration.Smart filter adopts membrane filtration and IX to filter.The present invention grinds to form bone meal with animal bone, increases the specific surface area of bone meal, improves its speed of response, compares with traditional manufacturing of gelatin, and the production cycle shortened more than 60 days, and has reduced and polluted and consumption; Congeal intensity height, modest viscosity, transparency of products obtained therefrom of the present invention is good, and cost is low, the viscosity of gelatin with congeal strength matching, be suitable for making field of food such as candy.
