Desarrollo, caracterización y optimización de productos fermentados a base de licuados vegetales como alternativa a los yogures convencionales

Bernat Pérez, Neus 19 November 2013 (has links)
El proyecto de tesis tiene como fin desarrollar y caracterizar productos fermentados a partir de licuados vegetales con una excelente calidad nutricional y sensorial. Para conseguir el propósito mencionado se eligieron licuados de almendra, avellana y avena, cuyas propiedades fisicoquímicas y nutricionales son aptas para el proceso de fermentación. Para ello, se estudió el efecto de los tratamientos térmicos y de homogenización sobre las cualidades fisicoquímicas y de estabilidad de los diferentes licuados, para elegir en base a los resultados obtenidos, las condiciones idóneas de su obtención. Por otra parte, se seleccionaron dos cepas probióticas comerciales (L. rhamnosus GG y L. reuteri ATCC 55730) con el fin de obtener productos fermentados a partir de los licuados elegidos y, de este modo, ofrecer nuevas posibilidades y beneficios al consumidor dentro del sector de productos no-lácteos. Por otra parte, con la adición de microorganismos probióticos se pretende satisfacer la demanda actual de productos funcionales; es decir, ofrecer productos que, además del aporte de nutrientes, tengan un efecto beneficioso para la salud. / Bernat Pérez, N.

Furthermore, I analyzed agency data from continuous research MML-TGI that provided Median s.r.o. At first the target group is characterized by a general analysis. Afterwards I used factor analysis to reduce variables to the factors. And then I put women into clusters based on clusters analysis. The segments are described in detail using general and contingency analysis. Primary data are gained from own research through questionnaire survey. In the conclusion of diploma thesis there are presented the results of data analysis. Based on those results there are provided appropriate marketing recommendations for Nutrilon and uncovered segments. These recommendations should help Nutrilon in the future to become number one at the market of infant milks.
