Definitions
- the present invention relates to a method for producing a collagenous material in particle form.
- the invention further relates to a collagen material produced by this process in particle form.
- Such collagenous materials in particle form which are used as functional proteins in foods, have hitherto been produced directly from a collagen-containing animal raw material by comminuting it with a suitable process to the desired particle size (eg by wet or dry grinding).
- the raw materials used are primarily the skin and bones of animals.
- published patent application DE 10 2008 036 576 A1 describes a method for producing collagen particles from a solid collagen material, in particular from ossein.
- Such collagen particles can be used in particular in reduced-fat meats and sausages to contribute as a fat substitute to the typical texture of fatty foods.
- the object of the present invention is to propose an effective production process for a collagenous material in particle form.
- Phase an aqueous phase and a fatty phase
- the first step of the process according to the invention represents the essential process in the known preparation of gelatin.
- the soluble fraction of the collagen or the fraction which can be converted into a soluble form under the extraction conditions is separated from the raw material and the extraction solution is then concentrated and dried.
- the invention aims to also use the extraction residue in gelatin production (in whole or in part) for the production of the collagenous material in particulate form.
- the invention enables a significantly higher value added from the animal raw material used, which is processed in this way almost completely to high-quality, usable in the food industry products (gelatin and collagen particles).
- gelatin in the production of gelatin according to the prior art Technique of the extraction residue only as additive in fertilizers or in animal feed (for domestic and domestic animals) used.
- the collagen material prepared according to the present method despite its different composition, has substantially the same advantageous properties as a functional protein as a prior art collagen material prepared by crushing the unextracted raw material.
- the extraction residue is repeatedly extracted with an aqueous extraction solution, wherein at least a portion of the collagen-containing solid phase of the last extraction residue is mixed with at least a portion of the aqueous phase of the last extraction step.
- the aqueous phases of the preceding extraction steps can then be incorporated into normal gelatin production.
- the multiple extraction is a common procedure in the gelatin production, wherein in the individual extraction steps partly gelatins with different quality (in particular with different gel strengths) are obtained.
- the extraction is preferably carried out two to eight times.
- the properties of the collagen material produced can be significantly influenced, since with increasing number of extractions, the proportion of soluble or extractable collagen in the final product is smaller.
- the aqueous extraction solution is either an acidic solution containing in particular sulfuric acid or hydrochloric acid, or an alkaline solution containing in particular calcium hydroxide. Both the acidic and the alkaline extraction have long been known in the production of gelatin, the former leading to type A gelatin and the latter to gelatin from Type B. The decision for one of the two methods depends in particular on the type of raw material used.
- the properties of the collagen material produced can be influenced in particular also by the specific extraction conditions, that is, above all, the temperature, the pH and the extraction time. How these parameters can affect each other is shown below in the context of exemplary embodiments.
- the collagenous and fatty animal raw material is preferably selected from the skin and subcutaneous tissue of mammals, birds and fish. Particularly preferred is the use of pork rinds or cattle slit which are used in large scale gelatin production. Typically, acid extraction is performed on these raw materials, with the aqueous extraction solution preferably having a pH of from 3.5 to 5.5, more preferably from 4 to 5.
- the extraction time is preferably up to 30 hours, more preferably up to 25 hours, especially 15 to 25 hours.
- the raw material is comminuted prior to extraction in the usual manner, e.g. to a size in the range of about 5 x 5 cm.
- the two latter are mixed together in the process according to the invention, where appropriate only a portion of the resulting phases is used, that is. the mixing ratio is set specifically.
- the weight ratio of the collagen-containing solid phase to the aqueous phase is preferably in the range from 1:99 to 1: 1, more preferably from 1: 9 to 1: 2.
- the choice of this mixing ratio also influences the properties of the collagen material produced can be, in particular, by a higher proportion the aqueous phase, the viscosity of the product can be reduced (see the embodiments below).
- the drying of the mixed phases is preferably carried out to a residual water content of from 2 to 20% by weight, preferably from 5 to 15% by weight.
- a low proportion of water increases the storage stability of the material and also influences its functionality, in particular the water absorption capacity
- the drying is preferably carried out at a temperature of 50 to 150 ° C.
- the usual methods can be used.
- Suitable drying processes are, in particular, drum drying, spray drying and disk drying.
- the comminution of the dried phase conveniently comprises milling.
- the collagen material is ground to an average particle size of 20 to 250 microns, more preferably from 50 to 150 microns. This size range is particularly suitable for positively influencing its texture when used in foods.
- the present invention further relates to a collagenous material in particle form, which is prepared by the method described above. Particular advantages of the collagen material have already been described in connection with the production process.
- the average particle size of the collagen material according to the invention is preferably from 20 to 250 ⁇ m, more preferably from 50 to 150 ⁇ m.
- the collagen material according to the invention preferably has a water absorption capacity of 1: 1 to 50: 1, based on its own weight.
- the material preferably has an emulsification capacity for fat and water of in each case from 1: 1 to 20: 1, based on its own weight.
- the invention also relates to the use of the collagen material according to the invention in particulate form in the production of foods, in particular meat and sausage products.
- the collagen material can also be used in the production of animal feed for pets and pets.
- pigskins were extracted six times under the conditions specified in each case with a sulfuric acid extraction solution. The last extraction residue was separated into a collagen-containing solid phase, an aqueous phase and a fatty phase, and the solid phase was mixed with the aqueous phase in the respective proportions. After drum drying, the material was comminuted to an average particle size of 150 microns.
- the measure of the water binding capacity is the gel strength of a 20% by weight gusty suspension of the collagen material. The suspension was heated to 60 ° C and measured the gel strength after cooling to 10 ° C after 20 hours.
- the gel strength of an emulsion in the ratio 1: 6: 6 serves as a measure of the determination of the emulsification capacity.
- the emulsion was set at 20 ° C and measured the gel strength after cooling to 10 ° C after 20 hours.
- the gel strength was measured in each case with a Texture Analyzer TA.XTplus, Ball SMS P / 0.75, at a penetration depth of 1 cm.
- the viscosity was determined for a 30% strength by weight suspension of the collagen material at 60 ° C., measured using an Anton Paar MCR 102 rheometer.
