[Preparation and characterization of low protein, cell structural material. II. Materials with cellular structure from carrot and white cabbage].
The molecular parameters and functional properties of low-protein materials with a cellular structure are determined by both the conditions of preparation and the kind of raw material used. Compared to alcohol-insoluble substance, the conditions of preparation were modified. When an alkaline extraction and a favorable combination of processing steps is used, materials with special low protein and high pectin contents result. In addition, such functional properties as water binding capacity and cation exchange capacity of the materials are improved. After having prepared various materials with a cellular structure from apple, carrot, and white cabbage, it was found that the amount of solvent needed and the yield, as well as the molecular parameters and the functional properties were also determined by the kind of raw materials used. For instance, material with a cellular structure from apple is low in protein and high in water binding capacity. Whereas, materials with a cellular structure from carrot, which contains a deesterified pectin component, is characterized by a good yield, a high pectin content, and an excess of 1.5 mmol/g of free carboxyl groups.
