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...
Effect of Erica sp honey against microorganisms of clinical importance: study o...
Feás, Xesús; Iglesias, Antonio; Rodrigues, Sandra; Estevinho, Leticia M.This study aimed to determine the factors (phenolic compounds, flavonoids, sugars or H2O2) that contribute the most to the antimicrobial activity of heather honey samples against four yeasts and four bacteria with medical importance. To discard the effect of H2O2 in the antimicrobial activity, catalase was added. To evaluate the osmotic pressure’s effect, artificial honey was also used. Phenolic compounds and f...
Organic bee pollen: botanical origin, nutritional value, bioactive compounds, a...
Feás, Xesús; Vázquez-Tato, Maria Pilar; Estevinho, Leticia M.; Seijas, Julio; Iglesias, AntonioOrganic bee pollen (BP, n = 22) harvested from the Douro International Natural Park (DINP, Portugal) was studied. Nine botanical families were found in the mixture of the samples. The water activity and pH ranged 0.21–0.37 and 4.3–5.2, respectively. The BP analyses averaged 67.7% carbohydrates, 21.8% crude protein, 5.2% crude fat and 2.9% ash. The energy ranged from 396.4 to 411.1 kcal/100 g. The principal fatt...
Commercial bee pollen with different geographical origins: a comprehensive appr...
Nogueira, Carla; Iglesias, Antonio; Feás, Xesús; Estevinho, Leticia M.Since the primordial of humanity, pollen has been considered a good source of nutrients and energy. Its promising healing properties have also been referred to. The present study aimed to characterize, for the first time, eight commercial pollens from Portugal and Spain available on the market studying the legislation on labeling, pollinic origin, physicochemical and microbiological analyses and identification ...
Characterization of artisanal honey produced on the Northwest of Portugal by me...
Feás, Xesús; Pires, José; Iglesias, Antonio; Estevinho, Leticia M.Honey has always been regarded as a food which is advantageous for one’s health and as a product which has healing qualities. For this reason, is necessary to protect consumers from the fraudulent mislabeling of inferior honeys. The purpose of this study was to investigate some properties of artisanal honey samples (n = 45) collected from the Northwest of Portugal by using different honey analysis tests such as...
Palynological and physicochemical data characterisation of honeys produced in t...
Feás, Xesús; Pires, José; Estevinho, Leticia M.; Iglesias, Antonio; Araujo, José Pedro Pinto deHoney legislation has been addressed to establish the minimum marketing level of the product and the need for consumer protection through correct denominations. Research oriented toward assessment of floral origin and physicochemical properties may increase the commercial value of these products. The characteristics of thirty-one honeys produced in the Entre-Douro e Minho region in Portugal were studied. Pollen...
Pollen spectrum and physico-chemical attributes of heather (Erica sp.) honeys o...
Pires, José; Estevinho, Leticia M.; Feás, Xesús; Cantalapiedra, Jesus; Iglesias, AntonioHoney legislation has been addressed to establish the minimum marketing level of the product and the need for consumer protection through correct denominations. Research oriented toward assessment of floral origin and physicochemical properties may increase the commercial value of these products. The characteristics of 23 unifloral honeys of Erica sp., from Portugal, were studied. Pollen features and some physi...
Colecistite aguda decorrente de hemorragia intraluminar da vesícula biliar após...
Salomão,Renato Manganelli; Magalhães,Nycole Carvalho; Silva,Flávio Volpato da; Iglesias,Antonio CarlosIsolated gallbladder injury following abdominal blunt trauma is rare and early diagnosis is difficult to make, particularly when no other organ is injured. However, ultrasonography is valuable for investigating gallbladder injuries. We report a case of isolated gallbladder blunt trauma presented as acute cholecystitis with hemobilia. In isolated blunt traumatic injury to the gallbladder, treatment options vary ...
