Gelatin is a protein substance won out of collagen found in the tissue of mammals, in the connection points of muscles and bones, bones and bones and other organs and in the skin. It is produced via long manufacturing processes from the skin, bones and connective tissue of the animals. There are 2 different manufacturing processes in order to win gelatin, the acid and alkaline method. In order to get gelatin the collagen fibers are exposed to alkaline hydrolysis (type B gelatin) or acid hydrolysis (type A gelatin).
Gelatin is a strong nutrient in terms of amino acid. Because its structure consists to 84-86% out of protein, it is a nutrient rich in protein.
Bloom is a measurement unit that describes the density of the gelatin. The measurement of the bloom grade is carried out by a 6.67% water-gelatin solution. With the help of texture analyzers a 4 mm force is applied to the center of the gelatin and by evaluating the population of such, the measurement is completed.
The wavelength is measured with the help of a spectrophotometer, products with a wavelength under 620 nm are considered clear and products with a wavelength under 440 nm are considered colored. These two values are shown in T% (transmittance).
Turbidity is measured with a Turbidimeter by applying a light in a 90 degree angle, the light refraction is then defined in form of NTU. (NTU= Nefolometric Turbidty Unit)
The point where the components of a products become stable, in other words don’t show any reaction. When mixing products with very different isoelectric points, they can react with one another and create the turbidity factor.
Conductive condition: The conductive function of objects or environments that pass heat or electricity less or more from one to the other. Thermal conductivity: The ability of an object to conduct heat. One of the ways to transfer heat is conducting. During the conduction, molecules are carried via motion. Heat is conducted through molecular interactions and exchange of mechanical energy from one point to the other of the heated object.
This is described as the deposition (aggregation) of two materials with undissolved structure within a product. The turbidity factor can create structures. To prevent this, products whose isoelectric points are compatible must be used (See Isoelectric Point)
The pH value is the unit of measure that describes the acidity or alkalinity of a solution. To determine the acidity or alkalinity of a substance, we use pH (potential hydrogen). The measurement is carried out according to the concentration of the acid hydrogen ions within the substance. The pH ranges from 0-14. 0 means very acidic and 14 very alkali. The pH value 7, on the other hand, means that the substance is neither acidic nor alkali but neutral.
The free water content of food (water activity) is decisive for chemical and microbiological degradation. Suitable water activity values are below 0.8 and the highest degree of safety is less than 0.4.
Viscosity describes the flow resistance of a liquid.
