Fermentation of milk enhances its nutritional value through improved bioavailability of nutrients and production of bioactive substances which have biological functions. Cultured buttermilk, it is an important fermented milk in the world. It is obtained from pasteurized skim or partly skim milk cultured with Lactococci and Lactobacilli as well as aroma producing strains. Lactic acid bacteria (L...

One noticeable feature that is shared by cabbages, leeks, garlic and onions, amongst others, is their strikingly pungent aroma and distinctive taste, mostly attributable to sulphur-containing chemicals. Indeed, it has been appreciated for many years that these vegetables contain large amounts of sulphurous materials that release volatile compounds, especially during the processes involved in fo...

The inoculation of a Debaryomyces hansenii strain in dry fermented sausages with reduced fat and salt contents was evaluated in terms of chemical, microbial and consumer acceptability. The implantation of the inoculated yeast strain was confirmed by RAPDs of M13 minisatellite. A reduction of 17e20% salt and 10e16% fat content was achieved. These reductions affected the sausage quality by produc...

Plant antimicrobials fulfil the needs of today’s consumer looking for wholesome food without chemical preservatives. These can be classified as novel compounds obtained from plants that delay microbial growth of pathogens and spoilage organisms in food. The antimicrobial activity of plant extracts that is observed in in-vitro conditions is quite different to its effect in complex food systems. ...

As an alternative on the search for functional food products, this study evaluated the use of sourdough in the preparation of wheat flour tortillas. The sourdough was elaborated with Lactobacillus sanfranciscensis and the wheat flour tortillas were prepared with different concentrations of mother sponge (5%, 15%, and 25%) and fermentation times (1 and 3 h) at room temperature (25 ± 2 °C). Quali...

In this study, the addition of Sweet lupin seeds flour (SLSF) in different levels (5, 10 and 15%) to wheat flour (WF) was evaluated. Dough mixing properties, bread physical characteristics and sensory properties were investigated. Increasing SLSF level in the SLSF-WF composites led to an increased water absorption, dough development time, C4 and setback torque, while it decreased flour moisture...

In this work sensory characteristics (appearance - color, brilliance, shape and surface; texture - structure, break, firmness and chewiness; aroma - odor and taste) of dietary chocolates of different compositions were evaluated, in parallel with color parameter measurements. Color was determined instrumentally on the top and bottom surfaces, using a "MINOLTA" Chroma meter CR 400 thristimulus co...

Parallel brewing trials were performed in laboratory brewery. For beer wort hopping, hop pellets of diff erent age (“slightly aged” and “strongly aged” one) and storage indexes (0.35 and 0.59, respectively) were used. During brewing were measured bitterness, utilization of -acids and index of -acids isomerization. Mature beers were evaluated by panel taste testing. Th e results of panel testi...

Coffee is one of the most popular beverages in the world, prepared and consumed in many different ways. Taste, aroma and composition of the coffee brew vary depending on the preparation method. Therefore, this study investigates the effect of different brewing methods on the polyphenol and methylxanthine composition and antioxidant capacity of thirteen different coffee brews. The content of tot...
