  1. Evaluation of physical properties of chocolate-like food using roasted burdock and cocoa butter equivalent (CBE), Ryo Umebayashi, Takayuki Murakami, Ryo Hirao, Haruhiko Koizumi, Satoru Ueno, 2nd Berlin Symposium on Structured Lipid Systems, 2024/09/30, Without Invitation, English, Euro Fed Lipid, Technical University of Berlin, Berlin, Germany, The mouth feel, one of the tastes of chocolate, is attributed to the crystalline polymorphism of cocoa butter, the raw material. Cocoa butter has six crystal polymorphs ranging from form I to form VI. Of these, form V cocoa butter crystallization is important in chocolate production because it has a melting point of about 33°C, just below body temperature, and provides a smooth mouth feel. However, d ue to climate change in recent years, the production of cacao beans, the raw material for chocolate, has decreased significantly, and due to the rapid increase in chocolate consumption worldwide, cacao beans are in short supply, and the price of cacao beans continues to rise, making it difficult to obtain cacao beans. Therefore, we focused on roasted burdock root and cocoa butter substitute (CBE) as non-cacao ingredients. Roasted burdock is rich in dietary fiber and polyphenols. Furthermore, it has been shown that roasted burdock root exhibits an aroma component similar to that of chocolate. Therefore, the purpose of this experiment was to compare the crystallization behavior and crystal polymorphs of CBE prepared with roasted burdock powder (RBP) and CBE, to clarify the effect of the addition of roasted burdock on the crystallization of CBE, and to find its usefulness as a new non-cacao chocolate-like ingredient. First, samples of CBE alone and CBE plus 5% each of RBP or cocoa powder (CP) were prepared. CP was used to see the effect of different powders. After the samples were thoroughly melted at 50°C, hand tempering was performed. During the cooling and isothermal holding process, changes in crystal polymorphism and volume were investigated by synchrotron radiation X-ray diffraction (SR-XRD) measurements. In SR-XRD measurement, The appearance time of the β₂ form of CBE corresponding to the V form of cocoa butter was 21.5 min for CBE alone , whereas it was reduced to 14.5 min for the sample with CP and 10.5 min for the sample with RBP, respectively. These results indicate that CP and RBP promotes the crystal nucleation in the β₂ form of CBE. RBP has ample potential as a new non-cacao food alongside chocolate.
  2. Controlling Crystallization Behavior of Cocoa Butter by using High Intensity Ultrasound and Stirring Simultaneous Stimulation, Zining Wang, Haruhiko Koizumi, Satoru Ueno, 2nd Berlin Symposium on Structured Lipid Systems, 2024/09/30, Without Invitation, English, Euro Fed Lipid, Technical University of Berlin, Berlin, Germany, 1. Introduction CB (cocoa butter) is one of the components of chocolate, and CB shows 6 polymorphic forms. Among them, the Form V shows the most suitable melting point and stability for edible use. The traditional method to transform into Form V of CB is tempering, but it takes much time and the procedure is complex. Researchers figured out that CB crystallization can be controlled by using some external stimulations　such as applying high intensity ultrasound (HIU), stirring and so on. However, when applying these factors separately have their own limitations for only apply stirring needs an extremely high stirring rate, only applying ultrasound needs long crystallization time. Therefore, this study aims to show that whether CB crystallization transform to Form V more efficiently by using HIU and stirring simultaneously or not. 2. Experimental procedures Complete melting CB (Barry Callebaut Japan Ltd.) were presented in a polycarbonate sample cell with water jacket and the temperature was controlled by two thermostatic water baths. High intensity ultrasound (20 kHz, 100 W) and Stirring (0, 100, 200, 300 rpm) was applied respectively or simultaneously during the cooling and solidification of CB. The processed sample were kept at a constant temperature of 20 ℃ for 50 min. Time-resolved measurement of the crystallization and polymorphic transition process was detected by SR-XRD. Melting behavior of samples was measured by DSC (DSC 7000X, Hitachi Co.). Also, the rheological measurement of CB was detected by Rheometer (MCR 300, Anton Paar Japan K.K.). 3, Result and Conclusion Form V shows in the cases when the stirring rate was 300 rpm, or HIU and stirring with a stirring rate over 200 rpm are applied together. No polymorphic transformation was observed after 50min when applied HIU only. In other cases, just form II transferred to form IV. This research shows that high speed stirring can promote the formation of Form V; the stirring rate needed can be decrease with the application with HIU.
  3. Effect of shear stress application and cacao mass addition on cocoa butter crystallization, Keigo Abe, Yukina Matsushita, Natsuki Yamada, Haruhiko Koizumi, Satoru Ueno, 2nd Berlin Symposium on Structured Lipid Systems, 2024/09/30, Without Invitation, English, Euro Fed Lipid, Technical University of Berlin, Berlin, Germany, Cocoa butter (CB), the main fats and oils component of chocolate, shows six polymorphs; six polymorphs, formⅠ-Ⅵ, differ in melting point, thermodynamic stability and density. Among them, the form V is the most favored in chocolate production. Therefore, the researchers are studying in crystallizing form V as quickly and effectively as possible. Based on previous studies, the most frequently used method to get form V is tempering. However, it takes a lot of time and is difficult to crystallize into the form V with 100% certainty. Therefore, more efficient alternatives to tempering have been studied. Since MacMillan et al. reported that the addition of shear stress enhanced crystallization of form V [1], there have been many reports on the effect of CB with shear stress on enhancing form V crystallization. However, the actual chocolate product contains solid particles such as sugar and cacao mass in addition to CB. Here, the aim of this study is whether the transition to form V can occur conventionally by applying shear stress to CB containing cacao mass. Cacao mass was added to the melted CB, held at 45°C for 15 minutes and allowed to cool at 15°C for 10 minutes. The temperature was then increased to 28 °C, held for 20 min and allowed to cool at 15 °C again for 10 min. Shear stress was applied by the stirrer at a rate of 300 rpm until before the start of secondary cooling. Between primary and secondary cooling, Synchrotron Radiation X-Ray Diffraction (SR-XRD) measurements were performed to observe the crystallization behavior of the samples. The results of the XRD measurements showed that the diffraction peaks of the unstable polymorph, form II, weakened and the diffraction peaks of the stable polymorph, form V, strengthened in both samples to which shear stress was applied, indicating that form V crystallized preferentially. Compared to the CB without cacao mass, the induction time of form V was faster in the sample with cacao mass, indicating that the crystallization of the stable polymorph was more accelerated by the addition of cacao mass.
