| The aim of this study was to evaluate the physical and chemical parameters of Williams pear, stored at 25 ºC for 15 days, with and without edible coating. Edible coatings prepared with alginate 2% and carrageenan 0.5% were tested. The analyses carried out on the samples were: weight loss, pH, soluble solids, firmness, and color. The edible coatings were characterized in terms of mechanical properties, permeability, thickness, and opacity. The results show that the application of edible coatings with carrageenan and alginate in pears influenced physical and chemical characteristics such as weight loss, pH, total soluble solids, color, and firmness of the fruit. However, the alginate coating showed the best results on pear conservation since it had lower... |

| Para caracterizar la miel existen diferentes métodos destructivos y no destructivos, donde se puede obtener información útil sobre las sustancias que la componen. Los métodos destructivos que se utilizaron en esta investigación fueron el análisis fisicoquímico y el análisis melisopalinológico. El objetivo de este trabajo fue caracterizar mieles tabasqueñas procedentes de diferentes regiones geográficas y diferente vegetación, mediante las técnicas antes mencionadas. Se analizaron 12 tipos de mieles; para el análisis melisopalinológico se utilizaron 12 muestras, una por cada localidad con la finalidad de describir el tipo de polen presente en estas mediante análisis cualitativos, así como la cantidad de polen a través de análisis cuantitativos; para el... |

| The aim of this research was to analyze and compare 17 honey samples, 11 organic and six non-organic Apis mellifera honey. The samples were analyzed concerning moisture, hydroxymethylfurfural, diastase index, water activity, color, total sugar, reducing sugar, sucrose, ash, viscosity, electrical conductivity, pH, acidity, and formol index. With the exception of acidity, reducing sugar and diastase index, the averages of other parameters were different between the two groups. All samples of organic honey presented moisture values between 23.50 and 24.40%. Among the nonorganic honey samples, two presented apparent sucrose amount upper the maximum limit established by the Brazilian Legislation. According to the quantitative analysis of pollen sediments in the... |
