Abstract
The invention relates to a gelatin preparation method by utilizing fresh water fish bones, belonging to the technical field of aquatic product processing. The invention takes the fresh water fish bones as the raw material, and after the crushing, pickling, laundering, liming, gelatin extraction, sterilization and drying, the gelatin product is produced. The invention enables the waste fish bones from aquatic product processing to obtain full utilization, prevents the massive fish bones from abandoning, frees the environment from pollution, and increases the economic benefit. The fish gelatin has special application in the photographic negative, the biological material and food industry. Nowadays, the fish gelatin is mainly applied in the clarification of alcoholic beverage and cosmetics.
Description
Technical field
A kind of method of utilizing freshwater fish bones to prepare gelatin belongs to technical field of aquatic product processing.
Background technology
Gelatin is the denatured products of collagen, it is the collagen product that is most widely used, it is that collagen a kind of bone from animal, connective tissue or the epidermal tissue transforms through preliminary treatment, again the general name of water-soluble, the class material that can congeal that extracts through proper temperature.The collagen water soluble, collagen can not be utilized by protease (except that Collagenase), and collagen can be decomposed by protease.
The fish-bone collagen derives from fish-bone collagen, so its amino acid composition is similar.The fish-bone gelatin has the character that a lot of mammal gelatin do not possess, and as low antigenicity, low denaturation temperature is easy to character such as decomposition.These character make isinglass at photographic negative, and biomaterial and food service industry have special application.Now, isinglass is mainly used in the clarification and cosmetics of inebriant.
Research for Isin glue collagen is not a lot of both at home and abroad, and the trend that enlarges was gradually just arranged in recent years.China is an aquatic products big country, but utilizes very insufficiently to leftover bits and pieces such as fish-bone, the fish-skin etc. of processing of aquatic products.A large amount of fish-bones are discarded, and make environment suffer very big pollution, have reduced economic benefit.Simultaneously, long by the gelatin cycle that the bone of pig and ox and tissue etc. are produced, and be subjected to diseases such as religion reason and rabid ox disease and perplex, and its scope of application is restricted.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing each gelatin of freshwater fish bones system, the leftover bits and pieces fish-bone of processing of aquatic products is fully used, a large amount of fish-bones is not gone out of use, make environment not contaminated, and increased economic benefit.
Technical scheme of the present invention: a kind of method of utilizing freshwater fish bones to prepare gelatin is a raw material with the freshwater fish bones, through pulverizing, pickling, washing, liming, put forward glue, sterilization and drying, makes gelatin product; Technology is:
Fish-bone is pulverized the back soak 2～20h with 0.1～1.0mol/LHCl, fish-bone: the weight ratio of HCl liquid is 1: 5, the disacidify of water flushing afterwards, the broken bone in washing back soaks 72～300h with the milk of lime of 2g/L～25g/L, liming is after the fish-bone of washing places heated in water solution to the 60～90 ℃ extraction 1～4h of pH6.0～7.5, collagen in the fish-bone is dissolved in the solution, solution filters, concentrates, the concentrate boiling sterilization, 50 ℃ of heated-air dryings, control moisture≤14% makes the collagen product.
Beneficial effect of the present invention: the present invention is fully used the leftover bits and pieces fish-bone of processing of aquatic products, and a large amount of fish-bones is not gone out of use, and makes environment not contaminated, and has increased economic benefit.Isinglass is at photographic negative, and biomaterial and food service industry have special application.Now, isinglass is mainly used in the clarification and cosmetics of inebriant.
The specific embodiment
Embodiment 1
Fish-bone is pulverized the back soak 20h with 0.1mol/L HCl, fish-bone: the weight ratio of HCl liquid is 1: 5, the disacidify of water flushing is afterwards washed the milk of lime immersion 300h of the broken bone in back with 2g/L, and liming is after the fish-bone of washing places heated in water solution to the 60 ℃ extraction 4h of pH6.0, collagen in the fish-bone is dissolved in the solution, solution filters, concentrates concentrate boiling sterilization, 50 ℃ of heated-air dryings, control moisture≤14% makes the collagen product.The finished product mean molecule quantity is big, and gel strength is lower, below 150 Bo Langmu.
Embodiment 2
Fish-bone is pulverized the back soak 2h with 1.0mol/L HCl, fish-bone: the weight ratio of HCl liquid is 1: 5, the disacidify of water flushing is afterwards washed the milk of lime immersion 72h of the broken bone in back with 25g/L, and liming is after the fish-bone of washing places heated in water solution to the 90 ℃ extraction 1h of pH7.5, collagen in the fish-bone is dissolved in the solution, solution filters, concentrates concentrate boiling sterilization, 50 ℃ of heated-air dryings, control moisture≤14% makes the collagen product.The finished product mean molecule quantity is little, and gel strength is lower, below 150 Bo Langmu.
Embodiment 3
Fish-bone is pulverized the back soak 10h with 0.5mol/L HCl, fish-bone: the weight ratio of HCl liquid is 1: 5, the disacidify of water flushing is afterwards washed the milk of lime immersion 200h of the broken bone in back with 10g/L, and liming is after the fish-bone of washing places heated in water solution to the 75 ℃ extraction 2h of pH6.8, collagen in the fish-bone is dissolved in the solution, solution filters, concentrates concentrate boiling sterilization, 50 ℃ of heated-air dryings, control moisture≤14% makes the collagen product.The finished product mean molecule quantity is moderate, and gel strength is higher, more than 150 Bo Langmu.
