The stability of chocolate is mainly influenced by cocoa butter re-crystallization during storage, shown through fat bloom (appearance of white layers of cocoa butter on chocolate surface). The aim of this study was to examine the influence of cocoa shell addition on stability of dark and milk chocolate over a one-year storage period. Dark and milk chocolates were produced in a ball mill. Four chocolates were produced, two with the addition of cocoa shell (5% in milk and 15% in dark) and two control chocolates without the addition. The effect of cocoa shell on chocolate stability was examined by determining total color change and whiteness index (calculated from parameters L*, a* and b* determined using chromameter), total polyphenol content (TPC) (using the Folin–Ciocalteau method) and thermo-physical properties (using differential scanning calorimetry). Total color change and whiteness index were lower in chocolates with cocoa shell than in control samples. Over a period of one year, milk and dark chocolate with cocoa shell had lower enthalpy. Total polyphenol content in all chocolates did not change significantly through the storage period, although chocolates with cocoa shell had lower TPC because part of the cocoa liquor was replaced with cocoa shell.

ABSTRACT Undeclared allergens in chocolate products have been responsible for numerous allergen-related recalls in the United States. A survey was conducted to determine the prevalence of undeclared milk and peanut in 88 and 78 dark chocolate bars, respectively. Concentrations of milk (as nonfat dry milk) or peanut in three samples of each chocolate product were determined with two milk- or peanut-specific enzyme-linked immunosorbent assay kits. In 75% of the chocolate bar products with a milk advisory statement, milk concentrations were above the limit of quantitation (2.5 μg/g [ppm]), with the majority having concentrations >1,000 ppm. An additional 67% of chocolate bars with a “traces of milk” statement contained 3 to 6,700 ppm of milk. Fifteen percent of chocolates labeled dairy free or lactose free and 25% labeled vegan were positive for milk, all with concentrations >1,000 ppm. Even for chocolates with no reference to milk on the label, 33% of these products contained 60 to 3,400 ppm of milk. The survey of chocolate products for peanuts revealed that 8% of products with an advisory statement contained peanut, with the highest concentration of 550 ppm. All nine chocolates bearing the peanut-free or allergen-free statement were negative for peanut, but 17% of chocolates with no label statement for peanut were positive for peanut at concentrations of 9 to 170 ppm. Evaluation of multiple lots of four chocolate products revealed that milk was consistently present or absent for the products investigated, but mixed results were obtained when multiple lots were tested for peanut. This study indicates that a large proportion of dark chocolate bars contain undeclared milk. The type of advisory statement or the absence of a milk advisory statement on products did not predict the amount or absence of milk protein. In contrast, a lower proportion of chocolates containing undeclared peanut was found. Consumers with food allergies should be cautious when purchasing dark chocolate products, particularly those that have an advisory label statement.

Purpose – The purpose of this paper is to evaluate the effects of substituting cow milk with soy milk in the standard milk chocolate recipe on the physical, chemical and sensory qualities of milk chocolate and obtain the best ratio of substitution. Design/methodology/approach – Milk chocolates were produced by substituting the cow milk in the standard recipe with soy milk powder at different ratios of soy milk to cow milk. Physical and chemical analyses were carried out using the standard methods to evaluate the major raw materials and chocolate samples, and the sensory evaluation of the chocolate samples was carried out using preference and difference tests. Findings – Soy milk contained the highest crude protein and crude fiber. The cut test results of the cocoa beans showed that the percentage of fully fermented cocoa beans was in agreement with the standard. Residimeter value (RV) of four chocolate samples (30:70, 20:80, 10:90, and 0:100) was the best. The nitrogen content and melting points of the chocolates samples were found to increase with increased inclusion of soy milk powder in the recipe. There was no significant difference (p<0.05) in taste, sweetness, smoothness, and overall acceptability of the 0:100 and 30:70; soy milk to cow milk samples. Practical implications – Soy-chocolate will be a new chocolate product with higher melting point and lower cost than the standard milk chocolate. The selling price of chocolate will be lower and thus affordable to low-income earners. Also, there will be an increased utilization of soybean. Originality/value – Soy-chocolate recipe is a new and additional recipe for the production of milk chocolate.

There is no metaphysics on earth like chocolate.” Chocolate is a blessing which contain almost all nutrients necessary for the growth of human health. In this study, composition of different branded chocolates available in Pakistan including Dairy milk, Chocolate chip, Toblerone (black), Toblerone (sweet), Nutella, Smarties, Now, Sonnet, Novella and Snickers were qualitatively analyzed in triplicate. We successfully study proteins, fats, carbohydrates, sugar, alcohol, caffeine, calcium, magnesium, zinc, iron and nickel in different branded chocolates. From the results it is confirmed that pH of all chocolates are 6-9 depend on the concentration of cocoa which is same as reported in literature. All the chocolates contain high amount of fats, sugar and carbohydrates. Protein is present in excess amount in Chocolate chips and Snickers while Smarties, Sonnet and Novella contain small amount of protein but absent in rest of chocolate samples. None of the chocolate sample contain traces of alcohol. All chocolates contain calcium except Nutella, Now and Toblerone (black) while magnesium is only present in Smarties. All chocolates contain nickel except Sonnet and Now, zinc is absent in Sonnet, Now, Smarties and Nutella whileiron is only present in Dairy milk and chocolate chips. Some samples like Dairy milk, Chocolate chip, Toblerone (black), Snickers and Toblerone (sweet) contain traces of caffeine which act as stimulant and reduced liver damage. From the given results it is also confirmed that chocolates contain important ingredients which are helpful for proper body functioning.

Chocolate elicits unique brain activity compared to other foods, activating similar brain regions and neurobiological substrates with potentially similar psychoactive effects as substances of abuse. We sought to determine the relationship between chocolate with varying combinations of its main constituents (sugar, cocoa, and fat) and its psychoactive effects. Participants consumed 5 g of a commercially available chocolate with increasing amounts of sugar (90% cocoa, 85% cocoa, 70% cocoa, and milk chocolates). After each chocolate sample, participants completed the Psychoactive Effects Questionnaire (PEQ). The PEQ consists of questions taken from the Morphine-Benzedrine Group (MBG), Morphine (M,) and Excitement (E) subscales of the Addiction Research Center Inventory. After all testing procedures, participants completed the Binge Eating Scale (BES) while left alone and allowed to eat as much as they wanted of each of the different chocolates. We found a measurable psychoactive dose–effect relationship with each incremental increase in the chocolate’s sugar content. The total number of positive responses and the number of positive responses on the E subscale began increasing after tasting the 90% cocoa chocolate, whereas the number of positive responses on the MBG and M subscales began increasing after tasting the 85% cocoa chocolate sample. We did not find a correlation between BES scores and the total amount of chocolate consumed or self-reported scores on the PEQ. These results suggest that each incremental increase in chocolate’s sugar content enhances its psychoactive effects. These results extend our understanding of chocolate’s appeal and unique ability to prompt an addictive-like eating response.

Abstract The characteristics in milk or dark chocolate Arthrospira products require testing before the product is released to the market. The purpose of this study was to use the Projective Mapping (PM) method to determine the characteristics and preferences of consumers toward milk or dark chocolate Arthrospira carotenoid products compared to commercial milk or dark chocolate products on the market, and to analyze the factors that can influence consumers’ purchasing intention. The chocolate samples tested were Arthospira milk chocolate and ten commercial milk chocolate samples (SQ, DF, LD, DV, CB, MG, VH, BB, TB, and WD). The dark one compares to ten commercial dark chocolates (SQ, M5, M6, M7, DC, WD, TB, BB, LD, and DV). The factors that influence consumers’ purchasing intentions are identified through an online survey and analyzed using chi-square. A total of 159 people (68 PM respondents and 91 non-PM respondents) took part in the milk chocolate poll, while 92 people (41 PM respondents and 51 non-PM respondents) took part in the dark chocolate poll. PM test shows consumers perceive milk chocolate and dark chocolate fortified with nanocapsules Arthospira carotenoid to be similar in taste, appearance, texture, and price to some commercial chocolate bar products, implying that both chocolate products fortified with nanocapsulesArthospira carotenoid can compete in the market. The results of the chi-square test for milk chocolate show that for PM respondents, socio-demographic factors, consumer habits of buying chocolate bars, knowledge of Arthrospira, and the benefits of consuming Arthospira influence their buying interest, whereas for non-PM respondents, consumer habits of buying chocolate bars influence their buying intention. The results of the dark chocolate chi-square test show that respondents’ knowledge of the benefits of consuming chocolate bars and the emotion conducted to consume chocolate bars and influence their purchasing interest.
