The Comparison of the Effectiveness of Cocoa Butter (CB) and Cocoa Butter Alternatives (CBA) in Chocolate Manufacture

This study aimed at (a) comparing the effectiveness of the use of Cocoa Butter (CB) and Cocoa Butter Alternatives (CBA) on food products and (b) measuring the effectiveness of the sub-groups of the Cocoa Butter Alternatives. In this study, the researchers used Structural Equation Modelling (SEM) with the Partial Least Square (PLS) approach. The analysis showed that (a) CB was more effective in the utilization than CBA and (b) after comparing sub-groups of the CBA examined in this study, Cocoa Butter Substitute (CBS) was more effective than Cocoa Butter Replacer (CBR) and Cocoa Butter Equivalent (CBE). This study is a practical recommendation for the use of CBA so that it can be widely applied in the chocolate industry.

The influence of the type of nut raw materials on the processes of migration of fats in glazed candies with pralin bodies

Целью исследования являлось изучение влияния свойств орехового сырья на направление и скорость процессов миграции жиров в глазированных конфетах с пралиновыми корпусами. Исследование процессов миграции жиров между корпусом и глазурью в процессе хранения необходимо для прогнозирования сохранности и предотвращения органо-лептической порчи в результате осветления или умягчения глазури, а также «поседения» поверхности изделий. Предложен подход прогнозирования скорости процессов миграции жиров при хранении конфет с корпусами, изготовленными на основе орехового сырья, с использованием удельной скорости миграции жиров. Исследованы процессы миграции жиров в модельных образцах конфет с пралиновыми корпусами на основе арахиса, фундука, кешью, миндаля, покрытых глазурью с использованием заменителя масла какао лауринового типа при температуре хранения 18 °С. Показано, что удельная скорость миграции олеиновой кислоты на поверхность модельных образцов глазированных конфет с корпусами на основе арахиса превышает скорость миграции в конфетах с корпусами на основе кешью приблизительно в 20 раз. Полученные закономерности позволяют установить дополнительные требования к качеству используемого жирового сырья для уменьшения скорости миграции жиров. The aim of the work - the investigation of the influence of nut raw material properties on the direction and speed of fat migration processes in glazed sweets with praline cases. The study of fat migration processes between the body and the glaze during storage is necessary to predict the safety and prevent organoleptic spoilage as a result of lightening or softening of the glaze, as well as «graying» of the surface of the products. An approach to predicting the rate of fat migration processes during the storage of sweets with cases made on the basis of nut raw materials using the specific rate of fat migration is proposed. The processes of fat migration in model samples of sweets with praline cases based on peanuts, hazelnuts, cashews, almonds, glazed with glaze, with the use of a lauric-type cocoa butter substitute were investigated at a storage temperature of 18 °C. It is shown that the specific rate of migration of oleic acid to the surface of model samples of glazed sweets with peanut-based cases exceeds the migration rate in sweets with cashew-based cases by approximately 20 times. The obtained regularities allow us to establish additional requirements for the quality of the fat raw materials used to reduce the rate of fat migration.

Restructuration Fatty Acid Oil Castor Being Cocoa Butter Substitute Through Dehydration Reaction Castor Oil And This Interesterification With Coconut Oil

The purpose of this research to restructuring its acid fatty oils castor result of dehydration with coconut oil through the process interesterification to produce cocoa butter substitute (CBS). Coconut oil is obtained from coconut milk by heating it slowly over low heat. The resulting coconut oil has a FFA is 1.667%, a peroxide is 10.229 MekO2 / Kg and an iodine is 7,7080 gI2/100g, which meets the second quality standard according to SNI 01-3741-2002. The restructuring was carried out by interesterification of dehydrated castor oil with coconut oil with a ratio (50:50); (60:40); (70:30); (80:20) dan(90:10)with a NaOCH3 catalyst. The results showed that the interesterification of dehydrated castor oil with coconut oil with a ratio (50:50) was the most optimal ratio with a melting point of 33 oC which corresponds to cocoa oil (32 oC-35 oC) and contain omega-6 fats (linoleic acid).

Fortification of chocolate using Moringa oleifera extract encapsulated in microemulsions

The aim of the present study was to evaluate the physical and antioxidant properties of microemulsions containing Moringa oleifera leaf extract (MLE) produced by the means of a deep eutectic solvent. Selected microemulsions containing MLE were incorporated in chocolate products to enrich them. Their color properties including CIE L*, a*, b* parameters and whitening index (WI) along with DPPH radical scavenging activity were assessed during a period of 8 months. The antioxidant activity of microemulsions depended on the oil phase used, while it was unaffected by the concentration of MLE. Samples prepared with soybean oil as oil phase containing MLE presented the highest radical inhibition percentage (I% = 26.8–27.8%). Coconut microemulsions were finally incorporated at 2 and 4% w/w concentration into chocolate products, as coconut oil is a known cocoa butter substitute. Although the incorporation of MLE microemulsions did not affect the color properties of most of the chocolates, enriched products did not exhibit superior antioxidant activity compared to control samples.
