Abstract
The invention discloses a collagen casing having a variety of application characteristics. The collagen casing is prepared by lamelliform and dispergated collagen fibers, a water-soluble collagen, vegetable fibers, a non-collagen type protein and glycerol. During preparation, the water content of the lamelliform and dispergated collagen fibers is adjusted to be 82 to 88% by means of water firstly, and then the lamelliform and dispergated collagen fibers are blended and kneaded with all other raw materials for 4 to 6 hours to obtain a collagen slurry material. After that, the water content of the collagen slurry material is adjusted to be 90 to 95% by means of water, and the pH value of the collagen slurry material is adjusted to be 2.5 to 3.0. Then, the collagen casing is shaped on a casing shaper and the pH value of the collagen casing is adjusted to be 4 to 6. After the drying and cooking process, a collagen casing finished product is finally obtained. According to the technical scheme of the invention, the collagen casing is good in mechanical strength during the casting and cooking process, and can be kinked and segmented at a high speed. During the cooking process, the collagen casing is free from being broken and is still good in chewiness. At the same time, a sausage prepared by the above casing is still kept in good shape and is prevented from being torn down, broken or decorticated during the water-boiling, frying and other high-temperature cooking process before eating.
Description
Technical field
The present invention relates to a kind of casing packaging material of meat product, specifically a kind of have Collagent casing for sausages of multiple application characteristic and preparation method thereof.
Background technology
Traditional casing is after striking process, make coat for filling and presenting sausage and bowel lavage from the large and small intestines of domestic animal at first, along with increase and the technical development of the market demand, Artificial Rubber collagen albumen sausage casing instead of the main status of beaters' skin gradually, becomes the main packaging raw material of current sausage food.Collagent casing for sausages production technology is firstly appeared from eighties of last century the forties and is obtained very large development so far, and its product is also widely used in the sausage production industry in meat food.
Take a broad view of the casing product of the existing collagen in market circulation, except production method is widely different, its products application characteristic does not have obvious difference.This is because adopt the product that the existing Collagent casing for sausages mode of production is produced, the casing when recording sausage is only limitted to the characteristic requirements of product not damaged, in the indexs such as casing shortening process unfallen bar (fracture), such as CN100551253C discloses one collagen protein enzymolysis and wants to ask making edible artificial casing, the method to be hydrolyzed to animal dermis by enzyme and to obtain collagen long fibre, rub through classification again, high pressure reels off raw silk from cocoons, the steps such as mixing are by collagenous fibres sectionalization knitting forming again, shape with ammonia, dry, sizing obtains tubulose casing, solve the casing occurred in sausage production process and tear problem.This kind of improvement to Collagent casing for sausages production technology often have ignored the Collagent casing for sausages prepared in such technology fill and produce the sausage product that obtains post sales, the quality problems produced due to the difference of edible way.Such as: sausage is fried before consumption, or first sausage is carried out when edible chafing dish rinsing, poach process is just edible, or the process such as carry out toasting/steam produce break, enter casing when hot water is rinsed or boiled be separated with intestines body come off, occur when cutting into slices casing curling, be separated etc. with intestines body.
CN 101715870 B discloses a kind of edible soy protein casing film, and be that, glycerine, polyvinyl alcohol, edibility fiber, glutaraldehyde former by water, soybean tempera are prepared, this casing can directly eat, and easily chews, and has certain mechanical strength; CN102907486 B discloses a kind of Collagent casing for sausages, this technology, when the problem of the existing Collagent casing for sausages mechanical strength deficiency of solution, heat sealability, resistance to water, is also realize cross-linking modified by aldehydes such as glutaraldehyde, glyoxal, formaldehyde, Pioloform, polyvinyl acetal, dialdehyde starch.This type of casing its preparation method is comparatively complicated, need to adopt chemical method carry out cross-linking modified thus obtain good mechanical strength by adding glutaraldehyde to soybean protein, the aldehydes chemical assistant adopted, if glutaraldehyde is food processing aid, itself is with penetrating odor, there is strong impulse effect to eyes, skin and mucous membrane, need in process the safeguard measure increasing production safety; Meanwhile, the materials such as the isoflavones that soybean protein itself contains can make to allow soy protein products have certain fishy smell, additionally need process, otherwise can produce certain impact to the local flavor of sausage goods when producing product.
Summary of the invention
The object of this invention is to provide a kind of Collagent casing for sausages, this Collagent casing for sausages record with shortening process in there is good mechanical strength, can high-speed kinking segmentation, without breakage during shortening, and have good chewiness; Meanwhile, in the high temperature cooking process such as the sausage prepared with this casing poach before consumption, frying, sausage can be made to remain good shape, can not produce tear, breakage, the phenomenon such as decortication.
Technical scheme of the present invention is as follows: a kind of Collagent casing for sausages, by the dispergated collagen fabric of thin slice, water-soluble collagen, string, non-SUB1095, prepared by glycerine, with the dry weight basis of the collagen fabric contained in the dispergated collagen fabric of thin slice, the quality proportioning of described each raw material is as follows: water-soluble collagen consumption is 6 ~ 12% of collagen fabric dry weight, string consumption is 10 ~ 18% of collagen fabric dry weight, non-SUB1095 consumption is 2 ~ 8% of collagen fabric dry weight, glycerine consumption is 3 ~ 9% of collagen fabric dry weight, described Collagent casing for sausages preparation process comprises the following steps: first with water, the moisture of dispergated for thin slice collagen fabric is adjusted to 82 ~ 88%, rub 4 ~ 6h obtain collagen slurry by mixed to itself and water-soluble collagen, string, non-SUB1095, glycerine again, water use regulation collagen slurry moisture to 90 ~ 95%, and regulate collagen slurry pH value to be 2.5 ~ 3.0, shaping on casing former, casing pH value is regulated to be 4 ~ 6, then through super-dry and shortening, obtained finished product casing.
When adopting said method to prepare Collagent casing for sausages, by following steps, carry out mixed rubbing after each raw material is processed further again: by moisture be 82 ~ 88% collagenous fibres raw material mix with water-soluble collagen, string, non-SUB1095, glycerine, at frequency 50 ~ 60kHz, process 10 ~ 20 minutes under the ultrasound condition of power 200 ~ 500W, then carry out mixed kneading for collagen slurry.
