Abstract
The invention is directed to a method for preparing a collagen powder and to collagen powder that can be used for the preparation of a satiety inducing food product. The collagen powder of the invention is suitable as a food additive in food products for the reduction of hunger and as a possible treatment of obesity and its pathophysiological consequences, such as metabolic syndrome.
Claims15
Method for preparing collagen powder, comprising the steps of:
- producing at a temperature of 50° C. or less a wet collagen product by subjecting a hide or skin to a size reduction step;
- an alkaline and/or an oxidizing treatment step;
- and a neutralizing step;
- followed by drying of said wet collagen product using a contact dryer, to obtain said collagen powder.
Method according to the previous claim, wherein the temperature of the steps for producing the wet collagen product is kept at 45° C. or less and preferably 40° C. or less.
Method according to any of the previous claims, wherein said drying of said wet collagen product is carried out at a surface temperature of said contact dryer of 155° C. or higher, preferably 160° C. or higher, more preferably 165±4° C.
Method according to any of the previous claims, wherein said animal hide or skin is selected from the group consisting of bovine, porcine and poultry, preferably bovine.
Method according to any of the previous claims, wherein, said alkaline and/or oxidizing treatment is performed at a pH value of 10 or more, preferably 11 or more, more preferably 12 or more.
Method according to any of the previous claims, wherein the neutralizing treatment results in a pH value of 6 or less, preferably from 5 to 6.
Method according to any of the previous claims, wherein the ground animal hide or skin is dried within 24 hours after grinding, preferably within 12 hours, more preferably within 6 hours, and most preferably directly after grinding.
Collagen powder product, in particular a collagen powder product obtainable by a method according to any of the previous claims, having a Bloom gel strength of at least 300.
Collagen powder product according to the previous claim, which is a bovine collagen product and which comprises less than 1 wt. % fat (dry matter basis) and at least 95 wt. % protein (dry matter basis;
- as determined by the N×5.52 method).
Collagen powder product wherein more than 99 wt. % collagen of the collagen molecules have the same molecular mass.
Collagen powder product according to the previous claim, which is a bovine collagen powder product wherein the collagen has a molecular mass of about 80 kDa.
