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.

Impact of processing on important cocoa off-flavour compounds

The compounds responsible for smoky and mouldy–musty off-flavours in fermented cocoa have recently been elucidated; however, their behaviour during further processing into chocolate was still unclear. The compounds 2-methoxyphenol, 3-methylphenol, 4-methylphenol, 3-ethylphenol, 4-ethylphenol, and 3-propylphenol known to contribute to smoky off-flavours showed a tendency towards a minor increase during roasting and processing into cocoa liquor. This increase amounted to 1.4-fold at the most, however, was clearly compensated by losses of 30–63% during further processing into chocolate mass and conching. Among the off-flavour compounds identified in mouldy–musty smelling cocoa, faecal, mothball-like 3-methyl-1H-indole showed a clear decrease during roasting and processing into cocoa liquor, at least at rather high roasting temperatures, and a further decrease during processing into chocolate mass and conching. In contrast, faecal, mothball-like 1H-indole substantially increased during roasting and processing into cocoa liquor, namely from concentrations below its odour threshold value to concentrations up to 8 times beyond its odour threshold value. During processing into chocolate mass and conching, 1H-indole remained virtually unchanged. The data suggested that the monitoring of off-flavour compounds at the incoming goods inspection in the chocolate industry should not be limited to the fermented beans as such but additionally include the analysis of a bean sample after test roasting to correctly assess the off-flavour potential of 3-methyl-1H-indole and 1H-indole.

(KUB - IK ) Mataram Macoa is a cocoa industry . The cocoa industry can produce chocolate with a cocoa material capacity of 87 kg per month or 1.0444 tons per year. Based on data from the Polewali Mandar Regency Statistics Agency, in 2018 the chocolate industry has a prospect that is still less proven with the data from BPS Polewali Mandar Regency, there is only 1 group of cocoa industry centers and the number of business units is 1 unit (BPS Polewali Mandar Regency, 2018).The company does not currently have a structured risk management to identify and mitigate risks that occur, especially in the supply chain function. By using the House of Risk method, the risks that may arise and their causes can be identified to simultaneously find ways to mitigate these risks to improve the operational quality of the Kelompok Usaha Bersama Industri Kecil Mataram Macoa and open opportunities to detect profitable business opportunities for the company. The purpose of this paper is to determine the causes of the dominant risk and design response measures in the Kelompok Usaha Bersama Industri Kecil Mataram Macoa. The basic method of writing is descriptive method and is implemented by using a case study method through a quantitative approach. The selection of respondents was carried out using purposive sampling technique. Methods of data collection by observation, in-depth interviews, questionnaires and literature study. The results of this paper indicate that in the activity plan there are 2 risks, in source activity there are 5 risks, in make activities there are 5 risks, in delievery activities there are 3 risks, and in return activities there is 1 risk. The risk treatment plan is designed to reduce the risk status for each risk event using a risk matrix

Dynamics of cocoa fermentation and its effect on quality

Several research efforts on cocoa have been focused on parameters for controlling the transformation process to guarantee homogeneity and quality of cocoa beans, the main raw material in the chocolate industry. The main changes that determine the final quality of cocoa—and also the product’s homogeneity—occur during fermentation, given the great number of factors that affect the process. This research seeks to identify the most relevant factors affecting quality in order to offer higher-quality and more homogeneous cocoa for the chocolate industry. The dynamics of the fermentation process were observed in three contrasting locations, monitoring different variables and evaluating the final quality of the cocoa. Results show that temperature and pH profile are the key factors to be monitored and controlled in order to achieve high-quality cocoa beans.

Total Fat Content and Fatty Acid Profile of Fine-Aroma Cocoa From Northeastern Peru

Cocoa beans are the raw material for the chocolate industry. In this study, the total fat contents and fatty acid profiles of fine-aroma cocoa beans of 30 cocoa ecotypes from northeastern Peru were evaluated. Results showed that SJJ-1 and ACJ-11 ecotypes from San Martin and Amazonas regions, respectively, presented highest percentages of total fat with an average of 30.49%. With respect to fatty acid profiles, it was found that cocoa ecotypes are composed of 10 fatty acids (C14:0, C16:0, C16:1, C18:0, C17:0, C18:1, C18:2, C18:3, C20:0, and C22:0); based on this profile, 5 clusters were determined. Cluster 5 had the highest content of C17:0 fatty acid (0.47%); however, the clusters 1, 2, 3, and 4 had the lowest content of this fatty acid (0.37%, 0.32%, 0.32%, respectively). The clusters 3 and 4 showed the highest content of C16:0 fatty acid (31.13% y 28.97%, respectively). The clusters 3 and 5 contained the highest content of the acid C18:1 (27.08% y 26.82%, respectively). The PCA found that C18:0 and C20:0 fatty acids are correlated, and are fundamentally opposite to C18:1, C16:0, and C18:3 acids. These results may be useful in identifying raw material for the development of specialty chocolates with better nutritional value than traditional cocoa.

Effect of Dietary Hazelnut Peels on the Contents of Fatty Acids, Cholesterol, Tocopherols, and on the Shelf-Life of Ripened Ewe Cheese

Hazelnut peel (HNP), a by-product from the chocolate industry, is considered to be a suitable ingredient to be included in the diet of ruminants. This study aimed to evaluate the effect of feeding dairy ewes with a diet containing HNP on ripened cheese quality, including fatty acid (FA) profile, cholesterol, and tocopherol content, as well as stability during storage under commercial conditions. In total, 10 experimental cheeses were produced with bulk milk obtained from ewes fed a commercial concentrate (C group; n = 5) or a concentrate containing 36% HNP in dry matter (HNP group; n = 5). After 40 days of aging, each cheese was sub-sampled into three slices: one was analyzed immediately (C0 and HNP0), and the other two were refrigerated and analyzed after seven days (C7 and HNP7) and 14 days (C14 and HNP14), respectively. Compared to C, HNP cheese had more than twice as many tocopherols and mono-unsaturated FA and respectively 38% and 24% less of cholesterol and saturated FA. Tocopherols and cholesterol levels remained rather stable up to 14 days of storage regardless of the experimental group, suggesting no cholesterol oxidation. Therefore, the inclusion of HNP in ewe diets could be a valid resource to produce cheese with a healthier lipid profile and higher tocopherols content.

Evaluation of the Thermal Inactivation of a Salmonella Serotype Oranienburg Strain During Cocoa Roasting at Conditions Relevant to the Fine Chocolate Industry

Cocoa roasting produces and enhances distinct flavor of chocolate and acts as a critical control point for inactivation of foodborne pathogens in chocolate production. In this study, the inactivation kinetics of Salmonella enterica subsp. enterica serotype Oranienburg strain was assessed on whole cocoa beans using roasting protocols relevant to the fine chocolate industry. Beans were inoculated with 107–108 log10 CFU/bean of Salmonella Oranienburg and roasted at 100–150°C for 2–100 min. A greater than 5 log10 reduction of S. Oranienburg was experimentally achieved after 10-min roasting at 150°C. Data were fitted using log-linear and Weibull models. The log-linear models indicated that the roasting times (D) needed to achieve a decimal reduction of Salmonella at 100, 110, 115, 120, 130, and 140°C were 33.34, 18.57, 12.92, 10.50, 4.20, and 1.90 min, respectively. A Weibull model indicated a decrease in the Salmonella inactivation rate over time (β < 1). Statistical analysis indicated that the Weibull model fitted the data better compared to a log-linear model. These data demonstrate the efficacy of cocoa roasting in inactivation of Salmonella and may be used to guide food safety decision-making.
