    Notes: The hygroscopic behaviour of freeze dried bananas at several temperatures is presented. The adsorption isotherms were of sigmoid shape and the particle size of the freeze dried materials did not affect the general isothermal behaviour. The limits for caking were found at a water activity (aw) of about 0.33 at 38°C. The results fit the Henderson equation quite well at the four temperatures under test.

    Notes: The effect of freezing rate, freeze drying temperature, added sucrose and anticaking agents, on the water sorption kinetics and hygroscopic equilibrium of freeze-dried passion fruit juice was investigated. Slow frozen samples (-45°C) were prepared in a Harris freezer and fast frozen ones were prepared in liquid nitrogen (- 195.8°C) and a dropping technique. A freeze-drier 12F Pilot Stokes was used to freeze-dry the samples, and the studies of hygroscopicity were conducted in an automatically controlled temperature and relative humidity chamber. The results show the significant influence of the rate of freezing and added sucrose on reducing product hygroscopicity.

    Notes: Some physical measurements were applied to silver bananas (Musa paradisiaca) during natural ripening, at room temperature. Changes in fruit weight, fruit diameter and skin thickness were determined, using gravimetric methods and a pachymeter. Both fruit pulp and skin experienced substantial weight loss during ripening. The average of skin thickness was reduced from almost 4.0 mm to 1.5 mm. The results were correlated to the most important chemical changes in the fruit, such as total acidity. starch, reducing and nonreducing sugars and soluble solids.
