Please find our product details below:CarrageenanA substance with hydrocolloid properties obtained from certain members of the class Rhodophyceae (red seaweeds).The principal commercial sources of carrageenans are the following families and genera of the class of Rhodophyceae:Furcellariacaea such as FurcellariaGigartinaceae such as Chondrus, Gigartina, IridaeaHypnaeceae such as HypneaPhyllophoraceae such as Phyllophora, Gynmogongrus, AhnfeltiaSolieriaceae such as Eucheuma, Anatheca, Meristotheca.Carrageenan is a hydrocolloid consisting mainly of the ammonium, calcium, magnesium, potassium and sodium sulfate esters of galactose and 3, 6-anhydrogalactose polysaccharides. These hexoses are alternately linked α-1, 3 and β-1, 4 in the copolymer. The relative proportions of cations existing in carrageenan may be changed during processing to the extent that one may become predominant.The prevalent polysaccharides in carrageenan are designated as kappa-, iota-, and lambda-carrageenan. Kappa-carrageenan is mostly the alternating polymer of D-galactose-4-sulfate and 3, 6-anhydro-D-galactose; iota-carrageenan is similar, except that the 3, 6-anhydrogalactose is sulfated at carbon 2. Between kappa-carrageenan and iota-carrageenan there is a continuum of intermediate compositions differing in degree of sulfation at carbon 2. In lambda-carrageenan, the alternating monomeric units are mostly D-galactose-2-sulfate (1, 3-linked) and D-galactose-2, 6-disulfate (1, 4-linked).Carrageenan is obtained by extraction from seaweed into water or aqueous dilute alkali. Carrageenan may be recovered by alcohol precipitation, by drum drying, or by precipitation in aqueous potassium chloride and subsequent freezing. The alcohols used during recovery and purification are restricted to methanol, ethanol, and isopropanol. Articles of commerce may include sugars for standardization purposes, salts to obtain specific gelling or thickening characteristics, or emulsifiers carried over from drum drying processes.Calcium propionateWhite crystals, powder or granules with not more than a faint odour of propionic acidFreely soluble in water, soluble in ethanolPreservative, antimould and antirope agentAgar-agarAgar is the dried hydrophilic, colloidal substance extracted from certain marine algae of the class Rhodophyceae. It is a polysaccharide, consisting primarily of D- and L-galactose units. About every tenth D-galactopyranose unit contains a sulfate ester group. Calcium, magnesium, potassium or sodium cations are also associated with the polysaccharide.Odourless or has a slight characteristic odour. Unground agar usually occurs in bundles consisting of thin, membranous, agglutinated strips, or in cut, flaked, granulated or powdered forms. It may be light yellowish orange, yellowish grey to pale yellow, or colourless. It is tough when damp, brittle when dry. Powdered agar is white to yellowish white or pale yellow.CaseinCasein is a salt, meaning it has no net ionic charge, of the element calcium. It has a number of interesting properties that make it useful in foods and cooking. Many people believe proteins are healthier if consumed when not denatured â one of the major lines of reasoning used in supporting a raw food diet. Denaturing occurs when a protein loses its inherent structure, due to high heat or acid for example, at which point it no longer acts in the ordinary manner. Casein, because of its structure, is not susceptible to denaturing.Thank you for taking the time to go through our business profile.
