It is used at low levels (below 0.5%),[3][4] and works by decreasing the friction between the solid particles (e.g. [2] PGPR can also be used to reduce the quantity of cocoa butter needed in chocolate formulations: the solid particles in chocolate are suspended in the cocoa butter, and by reducing the viscosity of the chocolate, less cocoa butter is required,[2] which saves costs, because cocoa butter is an expensive ingredient, and also leads to a lower-fat product. Polyglycerol polyricinoleate (PGPR) is a synthetic emulsifier widely used to stabilize water-in-oil (w/o) and water-in-oil-in-water (w/o/w) emulsions. 16 AGE (Sigma‐Aldrich, 99%), tBuGE (Sigma‐Aldrich, >99%), and the synthesized EEGE were stored over CaH 2 and distilled in vacuo over molecular sieve before use to remove traces of water. Suppliers / Providers of PGPR 90 Polyglycerol polyricinoleate. Lipase comes from a fungus of the Rhizopus genus, and more particularly from Rhizopus oryzae or Rhizopus arrhizus. [3], In a 1998 review funded by Unilever of safety evaluations from the late 1950s and early 1960s, "PGPR was found to be 98% digested by rats and utilized as a source of energy superior to starch and nearly equivalent to peanut oil. Polyglycerol polyricinoleate (PGPR) was obtained from Danisco. The advantages of PGPR may be increased by combining it with lecithin. Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids (usually from castor bean, but also from soybean oil).In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin to reduce viscosity.It is used at low levels (below 0.5%), and works by decreasing the friction between the solid particles (e.g. *Please select more than one item to compare Contact Triacylglycerol acylhydrolase, Compare Products: Select up to 4 products. Polyglycerol polyricinoleate coats solid particles and, with greater molecular weight, extends further into the lipid continuous phase, producing better steric stabilization (Rector, 2000; Schantz & Rohm, 2005; Vernier, 1998). The lipase comes from a fungus of the Rhizopus genus, in particular Rhizopus oryzae or Rhizopus arrhizus. However, the main application of PGPR is in the chocolate industry, where, besides its action as an emulsifier, it also has important properties as a viscosity modifier and thus improves the moulding properties of the molten chocolate. The invention relates to a method for obtaining polyglycerol polyricinoleate, comprising the esterification of polyricinoleic acid with polyglycerol catalysed by (free or immobilised) lipase.

Sigma-Aldrich, 98%), hexadecane (Sigma-Aldrich, ReagentPlus, 99%), It has a detectable and somewhat offputting aftertaste.... American chocolate makers have been lobbying for years to be allowed to add vegetable fats to their products so they can sell the cocoa butter at a higher profit to cosmetic manufacturers. For example, polyglycerol polyricinoleate (PGPR) which has low HLB value of 1.5 ± 0.5 strongly favors the formation of W/O emulsions and it is commonly used in formulation of W/O/W emulsions [5, 14]. [9], The FDA has deemed PGPR to be generally recognized as safe for human consumption,[1] and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has also deemed it safe. Polyglycerol polyricinoleate 4150 (PGPR) was graciously provided by Paalsgard (molar mass of 3000 g.mol-1 and HLB = 1.5) and Tergitol 15-S-12 was purchased from Sigma-Aldrich (Polyglycol ether, CAS number 68131-40-8, molar mass = 760 g.mol-1 and HLB=14.5). In 1978, the Scientific Committee for Food (SCF) established an acceptable daily intake (ADI) of 7.5 mg/kg body weight (bw) per day for PGPR.

An additional property of PGPR in chocolate is its ability to limit fat … Search results for Polyglycerol Polyricinolate at Sigma-Aldrich. 2.2. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm 3. The mobile carrier or extractant used was TOPO (tri-n-Octylphosphine oxide), supplied by Avocado Research Chemicals Ltd. (Morecambe, UK). The Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re-evaluating the safety of polyglycerol polyricinoleate (PGPR, E 476) used as a food additive. Other surfactants (e.g. *Please select more than one item to compare, 2 The food additive named polyglycerol polyricinoleate (PGPR) and identified with the code E-476 (PGPR) is used as emulsifier in tin-greasing emulsions for the baking trade and for the production of low-fat spreads. Oleate and linoleates are the other significant components. This food additive is a viscous amber coloured liquid. 9. In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin[2] to reduce viscosity. [5] It is made up of a short chain of glycerol molecules connected by ether bonds, with ricinoleic acid side chains connected by ester bonds. So far they have been thwarted, so now they have moved to using PGPR to lower the levels of cocoa butter while still remaining undetectable to most people. Spent mushroom compost was generated at Tyholland Farm All chemicals were used without further purification.

Polyglycerol Polyricinoleate (PGPR) E 476 is an emulsifier manufactured from Interesterified Castor oil fatty acids and Polymerized Glycerol. Castor oil is a vegetable oil pressed from castor beans. No adverse effects of polyglycerols or specific fatty acids were identified in studies reported in those opinions. Site Use Terms Interfacial tension measurement, rheological analysis, Z-average measurement, and visual observations were used to characterize W/O emulsion stability. It includes a mixture of triglycerides in which approximately 90 percent of fatty acid chains are ricinoleates. [4] It can also be used as an emulsifier in spreads and in salad dressings,[5] or to improve the texture of baked goods. [3] Both of these organisations set the acceptable daily intake at 7.5 milligrams per kilogram of body weight.
