TranslationsSyneresis
syneresis[sə′ner·ə·səs] (chemistry) Spontaneous separation of a liquid from a gel or colloidal suspension due to contraction of the gel. Syneresis a spontaneous contraction of a jelly or gel accompanied by exudation of the liquid. Syneresis occurs as a result of a closer packing of the three-dimensional structural network, which in jellies is formed by macromolecules and in gels by particles of the disperse phase. During syneresis, the structured system is converted into a thermodynamically more stable state. Syneresis is one manifestation of aging or “ripening” in different types of disperse structures, as well as in polymer and biological systems. It has considerable practical significance in the preparation of food products (cheese, cottage cheese), in rubber technology (preparation of latex products), and in the formation of chemical fibers from spinning solutions. syneresis
syneresis [sĭ-ner´ĕ-sis] a drawing together of the particles of the disperse phase of a gel, with separation of some of the disperse medium and shrinkage of the gel, such as occurs in the clotting of blood.sy·ner·e·sis (si-ner'ĕ-sis), 1. The contraction of a gel, for example, a blood clot, by which part of the dispersion medium is squeezed out. 2. Degeneration of the vitreous humor with loss of gel consistency to become partially or completely fluid. [G. synairesis, a taking or drawing together] sy·ner·e·sis (si-ner'ĕ-sis) 1. The contraction of a gel, e.g., a blood clot, by which part of the dispersion medium is squeezed out. 2. Degeneration of the vitreous humor with loss of gel consistency to become partially or completely fluid. [G. synairesis, a taking or drawing together]syneresis A degenerative shrinkage of the vitreous humour in which the gel breaks into liquid-filled particles, which coalesce and render it partially or completely fluid. It occurs in elderly individuals and may precede vitreous detachment. See synchisis scintillans; vitreous detachment.sy·ner·e·sis (si-ner'ĕ-sis) The contraction of a gel, e.g., a blood clot, by which part of the dispersion medium is squeezed out.
