condensation of the castor oil fatty acids. These values correspond with equilibrium water contents of 3600 and 1000 ppm, respectively, which are the cause of the discrepancies in the results obtained in the open-air reactor. The chemical structure is shown in Figure 6. Generally it’s safe to assume E476 is Vegan, as it’s essentially always made from either soybean oil or castor oil, however technically it can be derived … Despite the intimate relationship with fat metabolism, no evidence was found of any adverse effects on such vital processes as growth, reproduction, and maintenance of tissue homeostasis. is determined by the prctitioner according to intended use and place of use. They are utilized for the purpose of restoring nutrients lost or degraded during production, fortifying or enriching certain foods in order to correct dietary deficiencies or adding nutrients to food substitutes. E 476: Polyglycerol polyricinoleate . 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.

It is an FDA approved emulsifying food additive used to lower the viscosity of chocolate and salad dressings among other foods, but it has also found use as a skin conditioning agent as well as an emulsifier in cosmetic products (Cosmetic Database). It is important to note that these values are based on the protein content provided by Lowry’s method [83], which showed that the commercial lipase contained only 15% protein. Lipases (E.C. have been used. It can be seen that there was a large difference between the activity of the derivative obtained on the anion exchange resin and the activity of other derivatives. These results suggest that immobilisation had a beneficial effect on the activity and stability of both lipases [65].Lipase from Rhizopus arrhizus was selected for PGPR production because lower amount of enzyme is required to achieve the same final acid value [66]. P. Denecke, G. Börner, and V. V. Allmen, “Method of preparing polyglycerol polyricinoleic fatty acid esters,” GB2073232A, 1981. In addition to the stabilization of emulsions, foams, and dispersions, polyglycerol esters can act as aerating agents, dough strengtheners, rheology modifiers, crystal modifiers, antispattering agents, beverage clouding agents, humectants, solubilizers, or fat substitutes [19]. Ø  Spreadable oils (oil rate is less than 41%), Ø  Spreadable products (oil rate is less than 10%). However, the percentage of immobilized protein obtained with this lipase was approximately half that obtained with the other two lipases, and so the enzyme loading factor of this immobilized derivative was the lowest (8.59 mg E/g support). Known chemical methods for preparing this emulsifier involve long reaction times and high operating temperatures, which adversely affect the quality of the final product leading to problems of coloration and odors that could make it inadvisable for the food industry. The production of cyclic compounds similar to dioxane, which undergo further polymerization. ASTM D974-06, “Standard test method for acid and base number by color indicator titration”. Polyglycerol polyricinoleate Miscellaneous directive Normal fat consists of glycerol and fatty acids, for these products additional glycerol is coupled to the normal glycerol. The European Community (EC) regulates food emulsifiers in an analogous fashion to United States regulations, identifying the additives with E numbers. (1)Nutritional additives. E476 represents polyglycerol polyricinoleate (polyglycerol esters of fatty acids) an emulsifier made from fatty acids and glycerol. However, several studies revealed that Candida rugosa lipase was unsuitable for PGPR synthesis, and therefore others lipases were assayed for this purpose [65].A further twenty lipases from different sources were used, and the corresponding experiments of PGPR synthesis were performed. 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. It is known that temperature is a crucial parameter in every enzyme catalyzed reactor, but in this case, due to the special characteristics of the reaction medium (solvent free), temperature greatly influences viscosity, mass transport phenomena, and, as a consequence, the esterification rate [85]. It serves to produce better quality chocolate reducing cocoa oil quantity in chocolate industry. On the other hand, the maximum PGPR levels of use in foodstuffs ready for consumption in Europe are listed in Table 2 [55]. It has a good thermal stability. (2)Synthesis: reactions under this category can be further separated as follows. It is well known that chemical production of PGPR [40] is carried out in four stages:(1)preparation of the castor oil fatty acids,(2)condensation of the castor oil fatty acids,(3)preparation of polyglycerol, and(4)partial esterification of the condensed castor oil fatty acids with polyglycerol. The method of manufacture and analytical constants may also be defined. (c)Dehydration by-products, namely, acrolein, which must be removed by distillation. Palsgaard® PGPR 4150 is a polyglycerol polyricinoleate (PGPR) with unique functional properties. Another important application of PGPR is its use as a water-in-oil emulsifier for the production of low-fat spreads. Multiphase systems consist of two or more distinctive phases; systems typical encountered in foods are water-in-oil (W/O), oil-in-water (O/W), solid-in-oil, gas-in-liquid, gas-, solid- or oil-in-water, and so on. B. van Mechelen, R. A. J. Driessen, and H. Schenk, “Crystal structures of 1,3-distearoyl-2-oleoylglycerol and cocoa butter in the, H. Schenk and R. Peschar, “Understanding the structure of chocolate,”, R. Wilson and M. Smith, “A three-generation reproduction study on polyglycerol polyricinoleate (PGPR) in wistar rats,”, R. Wilson and M. Smith, “Human studies on polyglycerol polyricinoleate (PGPR),”, R. Wilson, B. H. Doell, W. Groger, J. It is often found in combination with E322 in chocolates.
