Kinetics and bixine extraction time from achiote ( L.).

The effects of the use of solvents (96% ethanol and PEG 400), solute ratios: solvent (1: 4 and 1: 6 w/w), extraction temperatures (50 and 60 °C) and leaching techniques (conventional and assisted by ultrasound) on the concentration and time of extraction of bixin from Achiote ( L.) were evaluated. The extraction kinetics were constructed, and their orders were determined.

Gel Drying by Refractance Window: Drying Kinetics and High-Quality Retention.

In most cases, conventional drying produces inferior quality products and requires higher drying times. A continuous pilot Refractance Window equipment was used to dry gel slabs of 5 and 10 mm thick at 60, 70, 80, and 90 °C, seeking a dry product with high-quality retention. Based on five empirical models, drying kinetics, diffusion coefficient, and activation energy were analyzed.

[A sanitation plan for a food distributor attending children and the elderly].

The responsibility for providing healthy food involves all members of the production chain from input supplier to the distributor and consumer of food. Children and older adults represent the most vulnerable consumers for acquiring food-borne illness (FBI), meaning that the risk factors produced in food-processing targeted for this population group must be reduced. A clean-up plan was thus designed and implemented following the guideline laid down in decree 3075/1997 to reduce FBI risk factors in a population of children and older adults.
