So far, gelatin and glue have not been digging off the poultry feet. Raw material used and. are mowed and skin, predominantly bovine and porcine.

Raw material during. preparation for gelatine extraction - or gleja has many washes - with water. The preparation of collagen feedstock is therefore characterized by a large consumption of calcium hydroxide water or other chemical agents and a large proportion of calcium or other undesirable waste water. Destruction of wastewater requires a great deal of chemi- cal and non-naturalization. a necessary up to three - month supply of processed material; and. correspondingly large storage and handling spaces and equipment.

Examples of use. and Process for the preparation of collagen raw material from poultry b-aces according to the invention:

Example . 1 _¥ ·

The feet are continuously crushed in the crusher to the workers under the suspension conveyor. OatdèldO Incas on the processing of poultry in the city by hanging them from shackles. The crushed feet are automatically transported by pneumatic conveying equipment to a storage tank. The crushed feet are washed 5 times with clean water at a weight of 1: 3 by weight of the feet and water, thus removing the blood and others you swim at the other side. After washing, they are mecrated in an acidic environment, preferably e.g. 2 to 4% dilute hydrochloric acid over a period of about 6 to 10 hours, in a ratio of 1: 2 of the treads and the cross-linking agent, until complete demalization is achieved. Then. the mcerating agent is drained and its residues are separated

Rinse 204 740 planes by washing with clean water at a ratio of 1 foot to 3 foot, total 3 to 4 times or continuous to 3 * 0 to 4 »0 pH of the raw material.

Example 2

The procedure is as in Example 1, with this. that the feedstock is conjugated with an agent, e.g. 1% calcium hydroxide solution - or 2 to. 3% acid, sulfur or 2 to 3% oic acid and the like. The canned raw material is stored or shipped to a moderate degree of processing, e.g. Platinum or gLuja. Washing with clean water removes the preservative from the raw material and proceeds as in Example 1.

Example -3

The procedure is as in Example 1, except that after the draining agent has been pumped off, the raw material is stored in a macerated state or transported to the city for further processing, e.g. gelatine or glues. The procedure is as in Example 1.

Claims (1)

OBJECT OF THE INVENTION Method of preparation of collagen raw material - from footpaths for production. gelatin or geja, characterized in that the feet are crushed, washed with clean water to clear blood and other components, then they are reflowed in an acidic environment, preferably in a 2 to 4% hydrochloric acid solution and finally by washing with water, it relieves the residue of the pickling agent, preferably to 3 * 0 to 4 * 0.pH 'of the raw material.
