Glyceride composition natural fats

The texture of fat is influenced by a number of factors, including fatty acid and glyceride composition, solid fat content, crystal size and shape, nature of die crystal network, polymorphism, mechanical treatment, and temperature history (1). Many of these factors are interrelated, making it difficult to establish the independent effect of each. It is well recognized diat different fats preferentially occur in either P or p form (Table 1). 

The ester class also comprises natural oils, such as vegetable oil [75] spent sunflower oil [940,941,992,993] and natural fats, for example, sulfonated flsh fat [161]. In water-based mud systems no harmful foams are formed from partially hydrolyzed glycerides of predominantly unsaturated Ci6 to C24 fatty acids. The partial glycerides can be used at low temperatures and are biodegradable and nontoxic [1280]. A composition for high-temperature applications is available [1818]. It is a mixture of long chain polyesters and polyamides.
