Caracterização e comportamento higroscópico do pó da polpa de cajá liofilizada

Abstract: R E S U M OA higroscopicidade de um alimento desidratado está ligada à sua estabilidade física, química e microbiológica. Este trabalho teve como objetivos a caracterização físico-química e o comportamento higroscópico dos pós da polpa de cajá liofilizada contendo maltodextrina (DE20). Foram feitas as análises de umidade, pH, sólidos solúveis, acidez total titulável, ácido ascórbico, açúcares, cor, higroscopicidade e o grau de caking. Para obtenção das isotermas os modelos de BET, GAB, Henderson e Oswin na tem… Show more

“…Oliveira et al (2014) observed degree of caking of 6.64% for yellow mombin powder. Oliveira et al (2013) obtained values of 0.03 and 0.09% for powders of grugru palm (Acrocomia aculeata) using a 1200-µm mesh sieve for the analysis of the powder obtained through lyophilization.…”

“…The hygroscopicity of the powder obtained by lyophilization showed values of 5.96%. Oliveira et al (2014) obtained hygroscopicity of 12.53% for whole lyophilized yellow mombin and 8.51% when maltodextrin was added. Tonon et al (2009) claim that maltodextrin reduces the hygroscopicity of dehydrated products because of its low hygroscopicity.…”

“…The isotherm is a curve that describes, at a specific moisture content, the equilibrium relationship of an amount of water sorbed by the components of the biological material and the vapor pressure or relative humidity, at certain temperature. Many authors studied the sorption isotherms of various products, such as crambe fruits (Costa et al, 2015a), Buchenavia capitata seeds (Costa et al, 2015b), lyophilized yellow mombin pulp (Oliveira et al, 2014), guava in powder , 'caju-de-árvore do cerrado' (Anacardium othonianum) (Caetano et al, 2012).…”
