Polymorphism of cocoa butter

Abstract: Largely by x-ray diffraction six crystalline states, I-VI, in order of increasing melting point, have been identified for cocoa butter. Of these states II, IV, V and VI are pure and identifiable with previously (or presently) identified polymorphs of 2-oleoylpalmitoyl stearin (POS), namely a-2, fl'-2, fi-3 ("V") and fl-3 ("VI"); V and VI representing distinct but very closely related crystalline structures. State I is a definite but fleeting and not readily characterized sub a state and may be a phase mixture,… Show more

“…One way of inducing the formation of stable crystals of cocoa butter is by reheating the formulation at lower temperatures (32.0 ± 2.0 °C). Thus, the unstable crystals (γ, α, β') with lower melting points are recrystallized into a stable form (β) (Willie, Lutton, 1996;Cohen, 2004;Richter, Lannes, 2007).…”

“…To avoid the formation of fat bloom, storage of the preparation at 32 ºC is suggested, before final storage at room temperature. In addition, the settling time of the product to begin the stability test should be extended beyond 48 hours to allow complete stabilization of the crystals of cocoa butter and hence the stabilization of the formulation of organic lip balm (Willie, Lutton, 1996;Cohen et al, 2004).…”

“…Par exemple, pour la matière grasse laitière anhydre (MGLA) caractérisée par une composition en triglycéri-des très variée avec plus de 200 espèces molé-culaires, les formes cristallines stables sont majoritairement des variétés b' [6]. Le polymorphisme du beurre de cacao est généralement décrit par six formes polymorphiques notées de I à VI dans l'ordre croissant des points de fusion [7,8]. Au niveau de la fabrication du chocolat, c'est la forme V qui est recherchée car elle donne au produit fini ses propriétés de texture, de brillance et de cassant.…”

“…For example, for the processing of chocolates, the inducement of the quasi-stable form V of cocoa butter is crucial among its six polymorphs (form I -VI) via thermal thawing, called tempering, processing through melt-mediated transformation. [9][10][11] In the melt-mediated transformation, it is generally agreed that the crystallization of TAGs depends on the presence of local 2017 © The Japan Society for Analytical Chemistry † To whom correspondence should be addressed. The temperature thawing, as called tempering, of triacylglycerols (TAGs) is an important processing method in food productions, such as chocolates, cream, confections, and spreads.…”
