Desorption isotherms and isosteric heat of niger grains (Guizotia abyssinica (L. f.) Cass.)

open access: yesAgro@mbiente On-line, 2018
Niger seed oil has excellent quality and quantity (30-50%) and is rich in polyunsaturated fatty acids, mainly linoleic acid (about 70%). Thus, control of environmental temperature and relative humidity, and of seed moisture content is essential to ...

Water activity vs. equilibrium moisture content [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2016
Water activity is an important parameter that can be used to predict the stability and safety of food with respect to the most microbiological and biochemical reactions, conditioned by its value. In other words, it describes the degree of the bound level

EQUILIBRIUM MOISTURE CONTENT ISOTHERMS OF MUNGBEAN [PDF]

open access: yesInternational Journal of Food Properties, 2002
ABSTRACT The moisture isotherms of mungbean were determined at temperatures of 35, 45 and 55°C using isopiestic method. The effect of initial moisture content of mungbean on equilibrium moisture content was also studied. Five different models namely, Henderson equation, Chung and Pfost equation, Halsey equation, Sehgal equation and G.A.B. equation were
