Com o passar dos anos, a busca por alimentos que melhorem a qualidade de vida tem sido aumentada, como por exemplo, os alimentos funcionais. O kefir é um tipo de leite fermentado produzido através da fermentação do leite usando os grãos, sendo estes, massas gelatinosas de cor branca ou amarelada que contêm leveduras e/ou bactérias. É um alimento probiótico, pois contém microrganismos presentes benéficos ao ser humano e, se consumido numa quantidade de, no mínimo, 106UFC/100 mL ou gramas do produto pode auxiliar na prevenção ou correção de alguns problemas de saúde, sendo eles diabetes, desnutrição, obesidade, doenças cardiovasculares e outras doenças crônicas não transmissíveis. O objetivo deste estudo foi cultivar 3 amostras de kefir à base de leite e realizar análises físico-químicas para quantificar e definir os elementos presentes neste alimento, como o teor de carboidratos, proteínas, umidade, cinzas e lipídeos. A metodologia aplicada para execução do trabalho ocorreu através de revisão bibliográfica utilizando como base artigos em periódicos científicos, livros, teses, dissertações e resumos de congresso, sendo selecionadas publicações entre 2015 e 2020, nos idiomas inglês, espanhol e português e pesquisa de campo, realizando o cultivo e as análises bromatológicas. Os resultados obtidos através da caracterização físico-química dos grãos de kefir são semelhantes aos relatados na literatura, havendo algumas diferenças decorrentes do clima, matéria-prima utilizada e cuidados no cultivo. Conclui-se assim que o kefir é um alimento benéfico à saúde, porém são necessários certos cuidados no cultivo e manejo para garantir sua qualidade.   CHARACTERIZATION OF MILK KEFIR REGARDING PHYSICOCHEMICAL COMPOSITION   ABSTRACT Over the years, the search for foods that improve the quality of life has increased, such as functional foods. Kefir is a type of fermented milk produced by fermenting milk using grains, which are gelatinous masses of white or yellowish color that contain yeast and/or bacteria.  It is a probiotic food, because it contains microorganisms present that are beneficial to humans and, if consumed in an amount of at least 106 CFU/100 mL or grams of the product, may help prevent or correct some health problems, including diabetes, malnutrition, obesity, cardiovascular disease, and other chronic non-transmissible diseases. This study aimed to cultivate 3 milk-based kefir samples and to conduct physicochemical analyses to quantify and define the elements found in this food, such as carbohydrate, protein, moisture, ash, and lipid content. The methodology used to carry out the study was a literature review based on articles in scientific journals, books, thesis, dissertations, and conference summaries, selecting publications between 2015 and 2020, in English, Spanish, and Portuguese, as well as field research, with cultivation and bromatological analysis. The results observed in the physical-chemical characterization of kefir grains are similar to those reported in the literature, with some differences resulting from climate, raw material used and cultivation care. It is thus concluded that kefir is a beneficial food to health, but it is necessary to take proper care in cultivation and management to ensure its health benefits. Descriptors: Functional foods. Probiotics. Cultured milk products.

The development of dairy products using probiotic microorganisms has been an important focus in the food industry. Thus, the present study aimed to evaluate the physicochemical, sensory and microbiological quality of fermented milk with addition of cupuaçu (Theobroma grandiflorum) flavor. The experimental design used was completely randomized, with five replicates, arranged in a 4 × 2 × 2 factorial scheme, consisting of fermented milk with addition of four different strains of probiotic bacteria (Lactobacillus casei shirota, Lactobacillus casei, Lactobacillus acidophilus and Lactobacillus paracasei), presence and absence of cupuaçu flavor, and two evaluation times (1 and 7 days of storage). The results allowed us to conclude that the bacterial strain B (Lactobacillus casei) led to higher values of L*, b*, %Brix and pH. In the presence of cupuaçu flavor, the values of pH, L*, b* and %Brix were significantly higher, which allows us to infer that cupuaçu pulp contributes to decreasing the values of pH and increasing the acidity, lightness, b* and %Brix of fermented milk. Fermented milk with addition of bacteria A (Lactobacillus casei shirota) in the presence of cupuaçu flavor showed reduction in pH and %Brix and, therefore, better acceptance by consumers and bioconservation. The presence of cupuaçu flavor in fermented milk with bacteria B (Lactobacillus casei) alters L* and b* at seven days of storage. Fermented milk with addition of cupuaçu flavor constitutes an opportunity and possibility for developing new flavors from Amazonian fruits, strongly contributing to the durability of dairy products, since the physicochemical, sensory and microbiological characteristics are enhanced within the standards of food safety.

<p>This study aimed to determine the chemical, sensory, and microbiological quality of eggurt that was mixed with various grains of sesame, green bean, and black soybean. The addition of grains starch was intended to improve the<br />chemical and sensory quality, as well as to maintain the viability of lactic acid bacteria (LAB) during drying. Eggurt was prepared by fermented milk and albumen inoculated with 5% Lactobacillus bulgaricus and Streptococcus<br />thermophillus (1:1) and incubated at 42°C to form a curd or the pH reached 4.5. Milk and albumen were pasteurized separately. Milk was pasteurized at temperature of 85°C for 30 minutes, while the albumen was pasteurized at<br />temperature of 63°C for 5 minutes. Dried eggurt was produced by mixing of eggurt and blended grain with a ratio of 2:1, and then dried at 50oC for 16 hours. After dried, the eggurt products were then sampled for chemical, sensory and<br />microbiological analysis. The results showed that eggurt mixed with sesame seeds had a highest score on texture (47.50), aceptability (43.06) and total lactic acid bacteria (5.67 log CFU/g) than eggurt mixed with black soybeans and<br />green beans, while eggurt mixed with black soybean had a highest score (P&lt;0.01) on acidity (43.85), fat (9.13%) and protein content (33.06%). There was no different effect between grain sources on degree of sweetness, lactose<br />concentration, pH and acidity levels. It can be concluded that eggurt-sesame has the best sensory and microbiological quality, while the best chemical quality was obtained from eggurt-black soybeans.</p><p><br />(Keywords: Quality, Dried eggurt, Milk, Sesame, Green beans, Black soybeans)<br /><br /></p>

Abstract The natural drying of in-shell Brazil nuts carried out by the extractivists is not effective in reducing contamination by aflatoxin-producing fungi. Thus the use of an artificial heater could prove to be a favourable method to bring about a rapid reduction in the moisture content of the nuts and thereby prevent fungal growth. Hence the objective of this study was to evaluate the efficiency of a natural convection-type drier with respect to the physical, physicochemical and microbiological quality of nuts after drying for 6 hours at 45 °C. A random block experimental design with two treatments (nuts before and after drying) was used, using 10 replications of 3 kg. The nuts were analysed for their moisture, ash, protein, dietary fibre, total carbohydrates and lipid contents, water activity, total count of filamentous, potentially aflatoxin-producing fungi, and also the quantification of aflatoxins B1, B2, G1, G2 and the total aflatoxins. There was no effect of drying on the Aspergillus flavus and Aspergillus parasiticus counts or on the physicochemical composition of the nuts, except for the ash content. However the moisture content of the nuts was reduced by 39.7% and there was a decrease in the contamination by pre-existing total filamentous fungi. The dryer was effective in reducing the average time taken for drying as compared to the traditional method used by extractivists.
