MC and HPMC
Methyl cellulose (or MC, E461) and Hydroxypropyl Methylcellulose (or hypromellose, HPMC, E464) are derived from cellulose. They are hydrophilic white powders in pure form and dissolve in cold (but not in hot) water, forming a clear viscous solution or gel. They are used as a thickener and emulsifier in various food products. When MC and HPMC are dissolved they form a thermo-reversible gel at higher temperatures, making them an ideal ingredient for e.g. potato croquettes or bake stable fruit fillings.
Preparing a solution of methyl cellulose with cold water is difficult: as the powder comes into contact with water, a gel layer forms around it, dramatically slowing the diffusion of water into the powder, hence the inside remains dry. A better way is to first mix the powder with hot water, so the MC or HPMC particles are well dispersed (and have a much higher effective surface area) in the water, and afterwards cool down this dispersion while stirring. This way no lumps are formed and the solution of the products is quite fast and complete. Another way to achieve easy solution in cold water is to prepare a premix from MC and/or HPMC with other powder ingredients to prevent lumping.
HPMC can be used to provide several health benefits to foodstuffs, such as reduction of blood glucose levels, maintenance of normal blood cholesterol levels and increased satiety effect. These claims have been approved by EFSA (EFSA Journal 2010;8(10):1739).
Acatris has several grades of MC and HPMC available, please contact our sales department to find out which grade is most suitable for your application.
