Application of Carrageenan in Food Carrageenan has strong stability and its dry powder won’t get degraded for long time exposure. It is also very stable in neutral or alkaline solution, and won’t get hydrolyzed even with heat. In acid solution (especially pH≤4.0), however, can easily get acid hydrolysis and the gel strength and viscosity […]
Thickening Property of Carrageenan Owing to the properties of carrageenan, it often acts as thickening, gelling, suspending, emulsifying and stabilizing agents in the food industry. In general, the viscosity of carrageenan is between 20 and 250mPas, so the viscosity available will be far lower than that of other thickening agents. For example, the viscosity […]
Gelling Property of Carrageenan 1. Influencing factors of gel strength One important property of κ-Carrageenan powder is that it can form various kinds of gels in water and cream-based food system at low temperatures. Gelation is the basic function of κ-Carrageenan powder. The influencing factors of the gelling property include the concentration of […]
Protein Response Property of Carrageenan 1. The Protein Response Mechanism of Carrageenan gum In the primary structure, the whole Carrageenan gum molecule becomes strong anionic in the molecule structure and its half-ester sulfate group (R－OSO3－) has a relatively strong negative charge. In addition, this group and the protein charged group, when the pH value […]
Compound of Carrageenan and Other Colloids Carrageenan is a hydrocolloid extracted from some red algae seaweed and can form specific properties by compounding with various kinds of colloids. There are mutual synergistic effects in carrageenan and locust bean gum, xanthan gum and locust bean gum, tragacanth gum and sodium alginate, tragacanth gum and […]
Carrageenan Application In Beer 1. Introduction As the market range of beer brands expands and the shipping distance extends, the competition between brands becomes more and more fierce. Meanwhile, brewers and researchers has taken great efforts to make the beer brewing, from raw materials to the whole brewing process and related equipment, move […]
Application of Carrageenan in Meat Products 1. Carrageenan assists in the gelling of protein. Protein is the most important factor that affects the yield, taste, and quality of meat products. Due to the protein response property of carrageenan and the mutual effects with the long chain of protein molecule, it can enhance the gel […]
Physical and Chemical Properties of Carrageenan – e407 The food grade carrageenan appears as translucent plates or powders in white or fawn with shrinkage in the slightly glossy surface. Odorless or with little odor, and tasteless, it has a great smooth mouth feel and it can swell in cold water, while it can form […]
The Rheological Properties of Carrageenan gel On account of its properties, carrageenan gel is often used in food industry as the thickening, gelatinizing, suspending, emulsifying and stabilizing agents. Besides, it is also widely used in medicine and fine chemical industries. However, the production and application of carrageenan have much to do with its rheological properties, […]
Properties and Application of Kappa-Carrageenan Carrageenan is a natural vegetable gelatin extracted from some red algae and widely used in such fields as food, daily chemical industry and medical research. Its properties such as the formation of hydrocolloid, gelling, thickening, emulsifying, film formation and stable dispersion has been booming the development of carrageenan industry. Carrageenan […]
