Lactic acid bacteria (LAB) and yeasts were selected on the basis of in vitro proteolytic activity against wheat gluten protein and then assayed as leavening agents for pizza dough. Ek Dusre Se Karte Hain Pyar Hum Serial Cast on this page. Trials were carried out to compare a proteolytic starter (Prt +), consisting of Lactobacillus sakei T56, Weissella paramesenteroides A51 and Candida krusei G271, and a non-proteolytic starter (Prt −), consisting of Lb. Sakei T58, W.
Paramesenteroides A58 and Saccharomyces cerevisiae T22. The proteolytic activity of the starter cultures was monitored immediately after mixing of the dough and throughout the fermentation process.
The proteolytic activity was assessed by analysing the salt-soluble protein (SSP) and the dioxane-soluble protein (DSP) fractions of the pizza dough by discontinuous SDS-PAGE. Only the Prt + starter exhibited considerable qualitative and quantitative changes in the electrophoretic patterns of the protein fractions extracted. After the fermentation, the Prt + and Prt − doughs were tested to evaluate the influence of the proteolytic activity on the mechanical properties of the dough before and after baking.

The pizza dough with Prt + strains showed an increase in viscous properties during the fermentation as compared with the Prt − dough. Internet Download Manager Free Key Generator. Moreover, an increase in the firmness of the crumb was observed in Prt + baked pizza dough. • Previous article in issue • Next article in issue.
Ascorbic acid (C 6H 8O 6) is an organic compound belonging to the family of monosaccharide. It is highly soluble in water, and is often called one of the secrets of the Mediterranean diet. Its use is widespread in the food industry is also important, having always been exploited for its antioxidant and stabilising ability. Many indeed are the additive formulations that take advantage of these properties. The purpose of this paper is to explain the characteristics that make ascorbic acid an important food additive and to emphasise the technical and legal issues related to its use in food productions. In particular, in the course of this employment, laws and scientific studies have been applied to the resolution of a lawsuit, having as its object the use of ascorbic acid in preparations of ground beef sold at a butcher shop.
