Halal Gelatin is pure and natural, Is made from cattle skin.
The raw material for gelatin manufacture is the naturally occurring protein collagen, which is commercially sourced from the meat industry. Each stage of the manufacturing process is rigorously controlled in modern laboratories to ensure purity and quality. The process of converting collagen into gelatin involves several cleansing and purification steps and the end result is a pale yellow dry powder which is a true foodstuff.
Gelatin contains:
84-90% protein
1-2% mineral salts
8-15% water
It is free from additives and preservatives
Cattle hides are the least used gelatin raw material in North America today. Gelatin recovered from bone is used primarily in photographic applications: some is used for pharmaceutical purposes. The so-called green bone from the slaughter of cattle is cleaned, degreased, dried, sorted, and crushed to a particle size of about 1-2 cm. The pieces of bone are then treated with dilute hydrochloric acid to remove mineral salts. The resulting sponge-like material is called ossein. From this point on in the manufacture of Type B gelatin, both cattle hides and ossein receive similar treatment.
Cattle hides are available from trimming operations in leather production. Cattle hides are usually dehaired chemically with a lime/sulfide solution followed by mechanical loosening.
For the production of Type B gelatin, both ossein and cattle hide pieces are subjected to lengthy treatment with an alkali (usually lime) and water at ambient temperature. Depending on previous treatment, the nature of the material, the size of the pieces, and the exact temperature, liming takes 5-20 weeks, usually 8-12. The process is controlled by the degree of alkalinity of the lime liquor as determined by titration with acid, or by making test extractions.
Ossein usually requires more liming than cattle hides. Additional lime is added to maintain an excess, thereby compensating for any consumed. During liming some deamination of the collagen occurs, with evolution of ammonia. After conditioning, the raw material is thoroughly washed with cold water to remove excess lime; the pH adjusted with acid; and the product extracted with hot water to recover the soluble gelatin.
Production Process
Pre-treatment
First of all, the fat and minerals are removed from the raw materials. Afterwards two different pre-treatment methods are used, depending on the raw material and on the final application of the gelatine.
Alkaline procedureThe connective tissue of cattle is highly interconnected and is therefore pre-treated with lime in a process lasting several weeks. This brings about a gentle change to the collagen structure. After this treatment, the collagen is soluble in warm water and can thus be separated from the rest of the raw material.
Acid procedureThe collagen connective tissue from pigskin is not so heavily interconnected. Here, a one-day acid treatment with subsequent neutralization and the intensive rinsing out of the salts is sufficient to extract the collagen.
Extraction
The pre-treated raw materials are now treated with hot drinking water and extracted in several stages. The temperature of the hot water is a parameter for the jelly strength: the lower the temperature of the water, the higher the gel strength (bloom value) of the extracted gelatine.
Cleaning
The extracted solutions are freed of traces of fat and fine fibres in high-performance separators. Even the finest impurities are removed by filtration, in a similar way to the beverages industry. In a last purification stage the gelatine is freed of calcium, sodium, residual acid and other salts.
Thickening
The gelatine solution is now concentrated in vacuum evaporators and thickened to form a honey-like solution.
Drying
The highly concentrated gelatine solutions are sterilized, cooled, set and dried under strict hygienic conditions. In this process, “gel noodles” are formed that are ground into grains when dry.
The quality and purity of the gelatine is ensured by detailed quality control.All of these steps are indispensable for gelatine manufacture and have been used for decades to manufacture high-quality gelatine.
