Feature: Beta cyclodextrin is a cyclic heptamer composed of seven glucose units joined "head-to-tail" by alpha-1.4 links. It is produced by the action of the enzyme, cyclodextrin glycosyl transferase (cgt)ú¼on hydrolyzed starch syrups. And it is white powder and there is a cavity in its molecule which can form inclusion compounds with a range of molecules. The solubility degree of beta cyclodextrin in water is 1.85, melting point is about 260íµ, internal diameter is 0.7-0.8nm.

Escherichia coliú¦negative Application: As food additive, beta cyclodextrin can inhibit the finished products oxidation, being decomposed by ray and heat and volatilization, maintaining stability of products. Beta cyclodextrin can also change liquid food into solid and exclude bitter taste and smell. Meanwhile, beta cyclodextrin can raise the stability of spice, essence and pigment, strenghthen emulsifying and moistureproof capacity and prevent the food turning bad. Whatí»s more, it can improve the taste keeping the good quality of food in order to be stored and transported easily.

Black cumin is a part of the buttercup family and the seeds are dark, thin, and crescent-shaped when whole. The seeds have been used for many centuries in the Middle East, the Mediterranean and India. Today, black cumin seeds are used as a seasoning spice in different cuisines across the world due to their nutty flavor. Besides their culinary uses, black cumin seeds also have a wealth of important health benefits and are one of the most cherished medicinal seeds in history. The seeds of the black cumin plant contain over 100 chemical compounds, including some yet to be identified. In addition to what is believed to be the primary active ingredient, crystalline nigellone, black cumin seeds contain: thymoquinone, beta sitosterol, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidonic acid, protein, vitamin B1, vitamin B2, vitamin B3, folic acid, calcium, iron, copper, zinc, and phosphorous.
