Developments in the fermentation process and quality improvement strategies for...
Iglesias, Antonio; Pascoal, Ananias; Choupina, Altino; Carvalho, Carlos Alfredo; Feás, Xesús; Estevinho, Leticia M.Mead is a traditional alcoholic drink derived from the fermentation of diluted honey in the presence of appropriate yeast. Its modern production, in general terms, involves the addition of nutrients to initial diluted honey, pasteurization, yeast inoculation, fermentation and removal of impurities. Undesirable events along the process have been reported; among them, we highlight: delayed or arrested fermentatio...
Transglutaminases: recent achievements and new sources
Martins, Ivone M.; Matos, Mauro; Costa, Rodrigo; Silva, Fátima; Pascoal, Ananias; Estevinho, Leticia M.; Choupina, AltinoTransglutaminases are a family of enzymes (EC 2.3.2.13), widely distributed in various organs, tissues, and body fluids, that catalyze the formation of a covalent bond between a free amine group and the γ-carboxamide group of protein or peptide-bound glutamine. Besides forming these bonds, that exhibit high resistance to proteolytic degradation, transglutaminases also form extensively cross-linked, generally in...
Effect of the temperature in the honey quality
Pascoal, Ananias; Lopes, Sara; Estevinho, Leticia M.; Carvalho, MarietaHoney is the natural sweet substance produced by Apis mellifera bees from the nectar of plants, secretions of living parts of plants, or excretions of plant-sucking insects on the living parts of plants, which the bees collect, transform by combining with specific substances of their own, deposit, dehydrate, store and leave in the honeycomb to ripen and mature (Decreto-Lei nº214/2003). This product can suffer a...
Evaluation of the sensory quality of monofloral honey
Estevinho, Leticia M.; Lopes, Sara; Pascoal, Ananias; Carvalho, MarietaHoney is an alimentary product much appreciated due to his aroma, flavor and nutritional characteristics. The sensorial analysis is important in the evaluation of the quality and authenticity of monofloral honeys. It considers attributes as color, aroma, consistence and flavor, which are interlinked and depend on the volatile compounds related with the fragrance of the flowers where the nectar was collected. Th...

Effect of storage conditions on the quality of the bee pollen
Estevinho, Leticia M.; Rocha, Joana; Pascoal, Ananias; Pereira, Ana Paula; Choupina, AltinoBee pollen (BP), is the result of the agglutination of flower pollens, made by worker honey bees, with nectar and salivary substances and collected at the hive entrance. The collection of AP is a relatively recent development, dependent primarily on the basic concept of scraping pollen of the bees' legs as they enter the hive. The objective of this work was to evaluate the effect of storage conditions in the ph...
Effect of temperature on the bioactive properties of bee pollen
Pascoal, Ananias; Rocha, Joana; Choupina, Altino; Pereira, Ana Paula; Santos, Luís; Estevinho, Leticia M.Bee pollen is flower pollen collected by the honey bee, Apis mellifera, for the purpose of feeding its larvae in the early stages of development. lt is recognized to be a valuable apitherapeutic product with potential for medical, health and nutritional applications. The objective of this work was to compares the effect of different storage conditions in the bioactive compounds and biological properties of bee ...
