Can Chocolate Be Classified as an Ultra-Processed Food? A Short Review on Processing and Health Aspects to Help Answer This Question.

Chocolate is a confectionery product whose consumption has increased, particularly dark chocolate. Chocolate is produced with varying amounts of cocoa liquor (CL), cocoa butter (CB) and cocoa powder (CP). The main chocolate types are dark, milk and white. Processing steps for chocolate production are described, and nutritional compositions examined for benefits and risks to health. Chocolate processing comprises steps at farm level, initial industrial processing for production of CL, CB and CP (common for all chocolate types) and mixing with other ingredients (like milk and sugar differing according to chocolate type) for industrial chocolate processing. All chocolate types present similar processing levels, and none involve chemical processing. Nutritional profiles of chocolate products differ according to composition, e.g., dark chocolate contains more CL, and so a higher antioxidant capacity. Chocolate is an energy-dense food rich in bioactive compounds (polyphenols, alkaloids, amino acids). Studies have demonstrated benefits of moderate consumption in reducing cardiovascular risk and oxidative and inflammatory burden, improving cognitive functions, maintaining diversity in gut microbiota, among others. In our view, chocolate should not be classified as an ultra-processed food because of simple processing steps, limited ingredients, and being an important part of a healthy diet when consumed in moderation.

Agaricus bisporus mushroom as partial fat replacer improves the sensory quality maintaining the instrumental characteristics of beef burger.

The effect of Agaricus bisporus (AB) mushroom as a fat replacer in beef burgers was evaluated. Four treatments were compared: control (0% AB, 20% fat) and 3 treatments with partial fat replacement: AB 5% (5% AB, 15% fat); AB 10% (10% AB, 10% fat); AB 15% (AB 15%, 5% fat). Mushroom addition increased moisture content and yield and decreased cooking loss and diameter reduction of the burgers. Formulations with the highest AB concentrations were lighter and redder than the control. AB incorporation affected texture, resulting in less hard and less chewy products. In general, lipid oxidation increased during the storage time, however the lowest values were observed in AB 15%, i.e. the lowest fat content and the presence of AB increased the oxidative stability. AB 10% and AB 15% had good overall liking and were sensorially characterized as juicy, tender and flavorsome burgers. The partial replacement of animal fat by AB is a promising strategy for developing a low-fat burger.

Comparison of ozone and chlorine in low concentrations as sanitizing agents of chicken carcasses in the water immersion chiller.

The aim of this study was to investigate the effects of the use of chlorine or ozone as sanitizing agents in the water of chicken immersion chilling, using the residual levels usually applied in Brazil (1.5 ppm), comparing the effects of these treatments on the microbiological, physicochemical, and sensory characteristics of carcasses. Chicken carcasses were chilled in water (4°C) with similar residual levels of ozone and chlorine until reaching temperatures below 7°C (around 45 min). The stability of carcasses was assessed during 15 days of storage at 2 ± 1°C. Microbiological, surface color (L*, a*, b* parameters), pH value, lipid oxidation (thiobarbituric acid reactive substances index), and sensory evaluation (on a 9-point hedonic scale for odor and appearance) analyses were carried out. The presence of Salmonella was not detected, coagulase-positive staphylococci counts were below 10(2) CFU/ml of rinse fluid, and Escherichia coli and total coliform counts were below 10(5) CFU/ml of rinse fluid until the end of the storage period for both treatments. Psychrotrophic microorganism counts did not differ (P > 0.05) between chlorine and ozone treatments, and both values were near 10(9) CFU/ml of rinse fluid after 15 days at 4 ± 1°C. pH values did not differ between treatments (P > 0.05) or during the storage period (P > 0.05). In addition, neither chlorine nor ozone treatment showed differences (P > 0.05) in the lipid oxidation of carcasses; however, the thiobarbituric acid reactive substances index of both treatments increased (P ≤ 0.05) during the storage period, reaching values of approximately 0.68 mg of malonaldehyde per kg. Samples from both treatments did not differ (P > 0.05) in their acceptance scores for odor and overall appearance, but in the evaluation of color, ozone showed an acceptance score significantly higher (P ≤ 0.05) than that for the chlorine treatment. In general, under the conditions tested, ozone showed results similar to the results for chlorine in the disinfection of chicken carcasses in the immersion chilling, which may indicate its use as a substitute for chlorine in poultry slaughterhouses.

Avaliação do perfil sensorial de alimento com soja sabor laranja / Sensory profile evaluation of soy prodct with orange flavor

Três produtos comerciais de alimento com soja sabor laranja (A, B e C), acondicionados em embalagem longa vida, adquiridos no mercado foram avaliados sensorialmente. A Análise Descritiva Quantitativa (ADQ) foi utilizada para traçar os perfis sensoriais, avaliando-se doze atributos levantados por 10 julgadores selecionados e treinados. A aceitação dos produtos foi avaliada por 30 potenciais consumidores mediante Teste Afetivo, realizado em laboratório, utilizando-se escala hedônica estruturada mista de 9 pontos. Os resultados da ADQ foram submetidos à Análise de Variância (ANOVA). Teste de Média de Tukey a Análise de Componentes Principais, já os resultados do Teste Afetivo (Aceitação) foram analisados pela ANOVA e pelo Teste de Média de Turkey. Os produtos A e B ficaram mais próximos entre si, o produto C diferiu do produto B (significativamente ao nível de 5 por cento) em todos os atributos, com exceção da doçura e amargor. Os produtos A e C diferiram em todos os atributos, com exceção do residual de edulcorantes e viscosidade. No teste afetivo, o produto A obteve as maiores médias e notas dos julgadores, não diferindo do produto B em nenhum dos atributos analisados
