    Comparison of cocoa butter crystallization by using different measuring techniques. Cocoa butter crystallization properties are important to produce high quality chocolate products. Therefore, characteristics for good and poor crystallization properties have to be found and measurement needs to be standardized.

    • Noncocoa Ingredients on Cocoa Butter Crystallization ...

      The non-cocoa ingredients in chocolate, i.e. sugar, lecithin, and milk powder, influence the crystallization of cocoa butter. Of the three ingredients, the effect of milk fat is the best documented. Although the exact mechanisms remain unknown, milk fat has been found to retard cocoa butter crystallization, delay transformation into higher melting polymorphic forms, and exhibit anti-bloom effects.

      At 17 °C, a three-step crystallization process was visible for pure cocoa butter, whereby first an unknown structure with long spacings between a 2L and 3L structure was formed that rapidly transformed into the more stable α structure, which in turn was converted into more stable β′ crystals.

      • Seeding Effects on Crystallization Behavior of Cocoa Butter

        The crystallization rates of cocoa butter with and without seeding were measured at 25 and 30°C with a viscometer to examine seeding eifects on the solidification kinetics of cocoa butter. Three polymorphic forms of cocoa buffer were used as the seed crystals to examine the influence of polymorphism.

        Jun 17, 2019 · Design of a cocoa powder tempering profile, however, requires that the mechanism of cocoa butter crystallization in cocoa powder be fully understood. Low‐fat (8–12%) and high‐fat (20–24%) cocoas were sourced from two commercial manufacturers at varying degrees of alkalization and compared with two commercial cocoa butters.

          Jan 01, 2017 · Cocoa butter crystallization in the presence of sorbitan mono- and triesters or canola oil was investigated. Solid-state surfactant esters accelerated early-stage cocoa butter solidification while suppressing later growth. Sorbitan tristearate showed the strongest effect, followed by sorbitan monostearate and sorbitan monopalmitate.

          Crystallization occurs when a vegetable butter melts, either intentionally or accidentally during warm conditions, and then cools back down too slowly. During transit, vegetable butters can melt or partially melt. As they re-cool, some butters, most particularly Shea Butter, can crystallize or become grainy.

            Cocoa crystallization detection via ultrasonic waves. When liquid cocoa butter forms into solid cocoa butter five types of crystals are formed, each with its own size, shape, and melting point. Out of those five types, only the beta V crystal type is desirable for use in chocolate, Foubert explained.
