Resumo: Leites fermentados probióticos são considerados alimentos funcionais, devendo conferir proteção às culturas. A alta pressão dinâmica (APD) vem sendo investigada como alternativa na produção de leite fermentado, pois altera a funcionalidade de alguns constituintes. Este trabalho objetivou avaliar o uso de leite submetido à APD na cinética de fermentação de S. thermophilus e L. acidophilus, bem como a viabilidade das culturas, as características físico-químicas e reológicas durante a estocagem refrigerada do leite fermentado probiótico.Leite (3% de gordura) foi submetido ao processo de APD (100MPa e 200MPa) e comparados com controle (15/5MPa), e avaliada a cinética de fermentação (pH), atividade proteolítica e a viabilidade durante a fermentação do L. acidophilus (Cap.2). Outro experimento foi realizado com leite (2% de gordura) submetido à APD (50/5MPa, 100/5MPa, 150/5MPa e 180/5MPa) e comparado com o controle (15/5MPa), no qual foi avaliada a cinética de fermentação de S. thermophilus em co-cultura com L. acidophilus (Cap.3), bem como o comportamento reológico (Cap.3) e as características físico-químicas (Cap.4) do leite fermentado probiótico durante a estocagem refrigerada. A cinética de fermentação de Lactobacillus acidophilus foi alterada pela APD (100MPa e 200MPa) em comparação com o controle (15/5MPa), aumentando consideravelmente o tempo de fermentação com o aumento da pressão, sendo que após 24 horas de fermentação as amostras apresentaram valores de pH 4,49 (15/5MPa), pH 4,72 (100MPa) e 4,93 (200MPa). A atividade proteolítica foi alterada, sendo que pressões elevadas reduziram a atividade, atingindo no final da fermentação uma redução de 21,39% (100MPa) e 35,89% (200MPa), quando comparadas com o controle. Além disso, as amostras submetidas à APD apresentaram menor número de células viáveis de L. acidophilus no fim da fermentação em relação ao controle (0,28 ciclos log) (p<0,05). A cinética de fermentação do Streptococcus thermophilus e Lactobacillus acidophilus não foi alterada pela APD. O comportamento reológico durante a fermentação de leite processado à 100/5MPa e 180/5MPa apresentou correlação positiva entre a pressão usada com a consistência do leite fermentado, gerando um produto com maior consistência. Além disso, o processo de APD aumentou a capacidade de retenção de água (CRA) em 9,15% e reduziu a sinérese espontânea do produto em 31%, entre o controle e a amostras processada a 180/5MPa. A viabilidade do S. thermophilus não foi (p<0,05) influenciada pela APD (50/5MPa, 100/5MPa, 50/5MPa e 180/5MPa) em comparação com a homogeneização convencional (15/5MPa) durante a estocagem refrigerada, reduzindo a contagem em aproximadamente 0,2 ciclos log em todos os tratamentos estudados. A viabilidade do L. acidophilus foi maior na amostra processada a 180/5MPa a partir do 14° dia, em comparação ao controle (15/5MPa). O pH apresentou uma pequena redução (p<0,05) somente na amostra processada a 180/5MPa no ultimo dia. A atividade proteolítica das culturas não foi influenciada pela ADP. Os resultados demonstraram que a APD pode melhorar a textura de leite fermentado, aumentar a capacidade de retenção de água, reduzir a sinérese e alterar a cinética de fermentação, dependendo da cultura utilizada. No entanto, a viabilidade das culturas, a redução do pH e a atividade proteolítica não sofreram alterações expressivas pela APD, apesar de apresentar diferenças significativas
Abstract: Probiotics fermented milk are considered functional food, should provide protection to cultures. Dynamic high pressure (DHP) is being investigated as an alternative in the production of fermented milk, because changing the functionality of some constituents. This study evaluated the use of milk submitted to DHP in fermentation kinetics of S. thermophilus and L. acidophilus, as well as the viability of the cultures, the physico-chemical and rheological during refrigerated storage of fermented milk probiotic. Milk (3% fat) was subjected to the process of DHP (100MPa and 200MPa) and compared with control (15/5MPa), and evaluated the kinetics of fermentation (pH), proteolytic activity and viability during fermentation of L. acidophilus (Cap.2). Another experiment was performed with milk (2% fat) subject to DHP (50/5MPa, 100/5MPa, and 150/5MPa 180/5MPa) and compared with the control (15/5MPa), in which was evaluated the kinetics fermentation of S. thermophilus in co-cultured with L. acidophilus (Cap.3), and rheological behavior (Cap.3) and the physico-chemical (Cap.4) of probiotic fermented milk during refrigerated storage. The fermentation kinetics of Lactobacillus acidophilus was modified by DHP (100MPa and 200MPa), comparated to control (15/5 MPa) considerably increasing the fermentation time the higher the pressure used, and that after 24 hours of fermentation samples showed pH 4.49 (15/5MPa), pH 4.72 (100MPa) 4.93 (200MPa). The proteolytic activity was changed, with elevated pressures reducing proteolytic activity at the end of the fermentation, reaching a reduction of 21.39% (100MPa) and 35.89% (200MPa) compared with the control. In addition, the samples submitted to APD had lower number of viable probiotics in the end of fermentation compared to control (0,28 log cycles) (p<0.05). The fermentation kinetics of Streptococcus thermophilus and Lactobacillus acidophilus was not altered by DHP. The rheological behavior during fermentation in milk processed by DHP (100/5 MPa and 180/5 MPa) demonstrated a positive correlation between the pressure and consistency of the fermented milk. Moreover, the process of DHP favored water-holding capacity (WHC) in 10.13% and reduced syneresis spontaneous in 31% between the control and 180/5 MPa. The viability of S. thermophilus was not influenced by DHP (50/5MPa, 100/5MPa, 150/5MPa and 180/5MPa), comparated to conventional homogenization (15/5 MPa) during refrigerated storage, reducing the count in approximately 0.2 log cycles in all treatments. The viability of L. acidophilus was higher in the processed sample 180/5MPa from day 14, compared to the control (15/5 MPa). The pH showed a small reduction in sample subject to 180/5 MPa at the final day of storage. The proteolytic activity of the culture was not influenced by DHP. The results showed that the DHP may improve the texture of fermented milk, increase water-holding capacity, reduce syneresis and alter the kinetics of the fermentation. However, viability of cultures, the decrease in pH and proteolytic activity did not change by DHP, despite showing significant differences

Full textDairy products containing probiotics and/or symbiotics are leader in the functional foods market and, priority in research worldwide. The use of casein hydrolysate and co-cultures are useful to lower fermentation time, and, in addition, it enhances the probiotic stability. The aim of the work was to verify the growing conditions of Lactobacillus rhamnosus and Lactobacillus acidophilus in mixed cultures with Streptococcus thermophiles in milk supplemented with casein hydrolysate and whey protein with different amounts (3,05 to 17,05g/L). Response surface methodology was used to establish adequate relationship of casein hydrolysate and whey protein contents aiming their optimization. The performance of probiotic bacteria was compared with those of yogurt bacteria. The supplements influenced milk acidification. In all experiments, probiotic levels were higher than 106 cfu/mL, the minimal viable number suggested by many authors to have therapeutic benefits. Mathematical models were developed.

Full textFunctional food industry is in expansion mainly due to probiotic and prebiotic products. Studies have shown some probiotic strains develop immune modulation effect, however, these results are controversial and the mechanisms are not been well understood. Although, some probiotic strains increase IL-10 and γ-INF release modulating immune response, this response is weaker in probiotic strains when compared to pathogenic Gram-positive bacteria. The major aim of the present study was to assess the effect of probiotic fermented milk in cellular immune response of Balb/c mice colon. The specific objectives were: (i) to determine the immunomodulation of the milk added of probiotic in normal mice; (ii) to identify the cellular types implied in immune specific response and, (iii) to colocalize them in histological sections. Besides, the analyze and comparation of the probiotic resistance upon in vitro gastrointestinal and bioactive metabolites release in fermented or unfermented bifido milk using the same matrix, probiotic strain and probiotic dose in CFU. mL-1 were conducted. Dairy products were prepared in which variable form of technological appliance were: (i) milk, (ii) water, (iii) unfermented milk, (iv) fermented milk, and (v) fermented and heat treatment milk, all using Bifidobacterium subsp. lactis HOWARU HN019 strain in the same concentration. The skimmed milk and water were used as controls. The immune effects were evaluated by histological sections and the lymphocytic infiltrated was analyzed by flow citometry and histology.

Full textThe gastrointestinal tract of humans is rich in microorganisms which can both be beneficial to host health, preventing and / or treating lactose intolerance, constipation, irritable bowel syndrome, among others, as they can harm, affecting nutrient acquisition and the production of inflammatory mediators. These distinctive roles of intestinal microbiota are so striking that can even influence the development of obesity in some people and may even lead to metabolic syndrome. Probiotics and prebiotics can confer alterations in the microbiota properties, affecting the bacteria growth and their metabolism, and the use of nutrients. Thus, the aim of this study was to evaluate the use of innovative symbiotic fermented milk in obesity and metabolic syndrome indicators such as waist circumference, TGL, HDL-C, blood glucose and blood pressure in patients with a predisposition to this disease, selected according to the diagnostic criteria for metabolic syndrome. For this, four fermented mik were designed, three of them inoculated with a commercial probiotic culture - Bifidobacterium lactis (BL420), added or not by passion fruit peel powder (prebiotic), one of them being prepared with an emulsion of vegetable oil, which has effect on prolonguing satiety; and the fourth product, fermented only with the classical culture Streptococcus thermophilus. Products´ technological properties were evaluated - physico chemical, sensory, microstructure, microbiology, and functional aspects were studied. Finally products were tested in consumers throughout a clinical trial during 12 weeks, period in which the volunteers had to consume 100 mL of the product twice a day, every day. The evaluation of the volunteers was done before the start of the test and also at the end of the 90 days.

Full textThe present study aimed to evaluate the acidification kinectic and inter-relation between Streptococcus thermophilus TAO, Lactobacillus delbrueckii subsp. bulgaricus LB340, Lactobacillus acidophilus LAC, Lactobacillus rhamnosus LBA, Bifidobacterium lactis BL04 like association cultures in fermented milk. Five fermented milks were prepared and studied variable analyzed was the co-cultures composition. Acidification was monitored and the kinectic parameters were calculated. The products were submitted to physical chemistry and microbiological analyses during the storage at 4°C. The associations in mixed cultures promoted the reduction of fermentation time of the milks. During 21 days of storage, pH and firmness of fermented milks varied. Streptococcus thermophilus TAO, Bifidobacterium lactis BL04 and Lactobacillus rhamnosus LBA presented counts above 106 log cfu/mL. However, Lactobacillus acidophilus LAC and Lactobacillus bulgaricus LB340 were inhibited in mixed cultures demonstrating that these strains had difficulty to grow when in associated cultures with lactic acid bacteria.

Full textProbiotics dairy products and/or symbiotic are leaders in the functional foods market and have the research priority in several countries. The results of this study showed that the quality of fermented milk was strongly influenced by composition of probiotic co-cultures and different prebiotics, such as oligofructose, polydextrose, maltodextrin and inulin. The acidification kinetics was influenced by the composition of the probiotic co-cultures and prebiotic ingredients in the fermented milk. The milk supplementation with inulin reduced the fermentation time of the co-cultures of Streptococcus thermophilus + Lactobacillus acidophilus (St-La); Streptococcus thermophilus + Lactobacillus rhamnosus (St-Lr) and Streptococcus thermophilus + Bifidobacterium lactis (St-Bl), and improved the firmness of the probiotic fermented milk. It has also been observed that the amount of conjugated linoleic acid (CLA) increased in the milk fermented by the co-culture S. thermophilus + L. acidophilus supplemented with maltodextrin. As far as the bacterial counts are concerned, the inulin addition promoted the viability of probiotic bacteria during storage at 4°C and led to a bifidogenic effect, in vitro, stimulating the growth of B. lactis. As regards to the metabolic studies of the homofermentative co-cultures (St-La and St-Lb), studied in this work, it can be said that lactose was only partially fermented to lactic acid, galactose was metabolized to some extent, diacetyl and acetoin formed at appreciable levels. The acetoin and diacetyl were probably produced by the activities of α-acetolactate synthase and α-acetolactate decarboxylase of S. thermophilus.
