Rheological and some physicochemical characteristics of selected floral honeys from plants of caatinga Anais da ABC (AABC)
SANTOS,FRANCISCO K.G.; DANTAS FILHO,ANTONIO N.; LEITE,RICARDO H.L.; AROUCHA,EDNA M.M.; SANTOS,ANDARAIR G.; OLIVEIRA,THIAGO A..
The aim of this paper was to investigate the physicochemical characteristics and rheological behavior of some floral honeys from species of wild plants found in the Caatinga biome, as well as, correlate honey viscosities with its chemical composition. Thus, five honeys with floral predominance of typical plants foraged by honeybees in Caatinga were analyzed. Results showed that moisture content of honeys ranged from 17.45 to 21.50 g/100g. The samples exhibited higher fructose content (37.58 - 43.95 g/100g) and lower glucose content (27.41- 33.80 g/100g). The glucose-water ratio ranged from 1.55 to 1.80. Sucrose contents, excluding Croton campestris honey sample, exhibited values above the highest sucrose content (6.0 g/100g) allowed by Brazilian norm. The...

An empirical model to estimate the growth of ice crystals for storage of Tilapia at variable temperature conditions Ciênc. Tecnol. Aliment.
GUTIÉRREZ,Mirko Salomón Chávez; ARAÚJO,Luciares Costa de; SILVEIRA JÚNIOR,Vivaldo.
Abstract Empirical models can be used to represent the recrystallization process in frozen food as a simple strategy (limited by the complexity of the process). Anyway, the empirical model has a better fit when used within the range of experimental values from which they were generated. In this work, an empirical mathematical model derived from the Arrhenius equation was proposed, since in previous publications it was shown that there is a direct relation between the growth of ice crystals and the temperature oscillations that occur during the storage of frozen products. Equivalent diameter data of ice crystals obtained from the storage of frozen Tilapia analyzed in the optical microscope was used as a database for the formulation of the empirical model....
