    Background: Cream cheese is a fatty cheese that is popular with many consumers and highly nutritious. There are many studies to reduce its fat content by fat replacers. Flaxseed mucilage has the potential for stabilizing emulsions, thickening foods and gelling solutions. High-quality cream cheese is manufactured by replacing fat with flaxseed mucilage. Objective: This study aimed to prepare probiotic-fortified and fat-free cream cheese using flaxseed mucilage as a fat replacer and as prebiotic. Methods: The mucilage was extracted and added at different concentrations to the manufactured cream cheese during processing. Chemical properties, microbiological analysis and sensory evaluation of the produced cream cheese were investigated. Results: The results showed that the addition of mucilage to the cream cheese increased the protein, ash and the total solids while the moisture content and the pH values were decreased. Cream cheese viscosity significantly increased with the addition of flaxseed mucilage and decreased during the storage period. The results also showed that the combination of flaxseed mucilage and probiotic bacteria has potent antibacterial activity against some pathogenic bacteria like Pseudomonas aeruginosa and Yersinia enterocolitica. The mucilage improved the texture, enhanced the survival of the probiotic bacteria and improved the overall sensorial characteristics of the cheese. Conclusion: The manufactured product could be suitable for consumers having some health issues related to the consumption of fat and as sources of probiotic bacteria.

    Skim coconut milk is a liquid by-product of coconut oil production with limited utilization in food processing. It has nutritional value such as protein, carbohydrate and mineral, so it is possible to be used as raw material for processing food products, such as yogurt. The use of tofu waste flour and skim milk as prebiotic and protein source is intended to improve the physical quality of yogurt skim coconut milk. This study used a completely randomized design (CRD) with 2 factors and 3 levels (1,5%, 3%, and 4,5%), and several skim milk concentrations (10%, 12,5%, and 15%). The results of this study indicated that the addition of tofu waste flour and skim milk have no significant effect on the viscosity of the coconut milk yogurt. In the organoleptic test, the addition of tofu waste flour showed significant effect on panelist perception of flavor, aroma, and color. The higher the percentage of the flour, the lower the panelist preference on flavor, aroma, and color; flavor. High concentration of flour can increase the total of soluble solid content in yogurt. A concentration of 4.5% tofu waste flour and 15% skim milk produced 13,89 oBrix and 15,44 oBrix soluble solids resulting in the highest viscosity value of 609,6 Cp.

    Carob is widely cultivated Mediterranean plant, but its flour is scarcely used in bread making. Previous studies investigated the quality of wheat bread with added carob flour showing discrepant results. This study aims to investigate the fermentation performance, antioxidant activity, rheological behaviour and baking application of carob sourdough.Carob sourdough was fermented with Lactobacillus brevis or Lactobacillus fermentum combined with Saccharomyces cerevisiae for 24 h at 30 °C. At the end of sourdough fermentation, number of viable lactic acid bacteria and yeast cells, total titratable acidity, pH value, antioxidant activity, phenolics and sugar content were determined. Carob flour (12% flour mass fraction) or sourdough equivalent (22.5% dough mass fraction) was applied in making composite partially baked frozen bread. Dough rheology was monitored using a farinograph. Nutritive value, physical properties and sensory attributes of the rebaked bread samples were evaluated using a hedonic test.By the end of fermentation, carob sourdough reached pH=4.2-4.5 and total acidity 9.9-12.3 mL of 0.1 M NaOH, sugar content on dry mass basis was reduced by 8 g/100 g, while total phenolics and antioxidant activity were increased up to 21%, depending on the starter culture. Addition of carob flour or sourdough to wheat dough resulted in firmer consistency, longer development time, and lower quality number. Regardless, bread with carob flour had significantly improved specific volume. Compared with common wheat bread, carob bread had increased dietary fibre content (46%), total phenolics (140-200%) and antioxidant activity (240-300%), higher shape, larger volume, reduced crumbliness, unchanged firmness and darker crumb colour. Consumer preference and overall acceptability scores of carob sour bread were comparable to those of wheat bread, falling into the category of 'liking very much'.To our knowledge, this is the first study that proved the feasibility of carob sourdough fermentation using mixed starter cultures, where L. brevis together with S. cerevisiae was better adapted to the substrate than L. fermentum. The carob sourdough could be used as a natural ingredient for improvement of nutritive value and reduction of crumbliness of partially baked frozen bread.

    Recent advances in functional food research fostered new food ingredients that can alleviate the properties already found in these foods. Among them, product diversification in fermented foods totally benefitted because of the array of raw materials that can be mixed with milk-based fermented milk products like yoghurt. Legumes were reported to have bioactive ingredients that can potentially increase the beneficial effects of yoghurt by increasing the viability of yoghurt starter cultures. In this study, the effect of supplementation with gelatinized pigeon pea flour on the microbiological, physicochemical, and sensory properties of yoghurt during 14 days of refrigerated storage was determined. Supplementation of yoghurt with gelatinized pigeon pea flour significantly increased the viability of Lactobacillus delbrueckii subsp. bulgaricus, fermentation rate and total titratable acidity, and significantly lowered the pH of the supplemented yoghurt. However, no significant effect on the viability of Streptococcus thermophilus was found. Results of sensory evaluation showed that the addition of gelatinized pigeon pea flour to yoghurt significantly affected the colour, texture and consistency of yoghurt, and imparted a perceivable aftertaste, but did not significantly affect the aroma, sourness, sweetness, and overall acceptability of the product. The findings suggested that pigeon pea flour can be considered a potential ingredient for yoghurt supplementation.

    ABSTRACT: Spaghetti was prepared from durum wheat supplemented with soy flour in order to make an inexpensive, highly nutritious food and to determine the effects of high levels of soy flour on taste and textural attributes. Up to 50% soy flour was incorporated into spaghetti, resulting in a protein content of 33.5% (compared with 15.4% for control without soy) and a lysine content of 1.75% (compared with 0.41% for control). Sensory analysis of enriched spaghetti containing up to 35% soy flour indicated no significant difference in flavor and texture compared with control without soy, in general. Spaghetti with 50% soy flour had slightly higher beany and bitter flavors compared with control. This study showed that a high‐protein and high‐lysine spaghetti can be made with 35% soy flour without adverse effect on flavor and texture and should result in greater acceptability of soy‐based foods.
