“…Before frozen storage, the hardness values of most pretreated samples were significantly (P \ 0.05) lower than those of fresh mangoes, probably due to osmotic dehydration causing lower water content and thus having a negative impact on the hardness. Similar results have been reported by Tedjo et al (2002), and Rincon and Kerr (2010). Moreover, samples pretreated in 50% osmotic solutions should not be subsequently frozen because of the higher osmotic pressure, which can possibly result in tissue shrinkage, as per our previous work (Zhao et al 2014a).…”

“…De acordo com RAOULT-WACK et al 22 , o aumento da temperatura favorece tanto a perda de água quanto o ganho de sólidos, devido, provavelmente, ao seu efeito positivo sobre a difusividade aparente das moléculas de água e do soluto no interior do produto. TEDJO et al 32 observaram que quanto maior a temperatura da solução osmótica, maior o grau de permeabilidade das membranas das células do tecido parenquimático de mangas. WALISZEWSKI et al 35 avaliaram a influência da temperatura e da concentração da solução de sacarose na taxa de transferência de massa durante a DII de fatias de banana e observaram que o aumento no valor de ambas as variáveis teve efeito significativo sobre a perda de água e o ganho de sólidos.…”

“…A qualidade da desidratação osmótica depende de fatores como a concentração, o tipo de agente desidratante, a temperatura da solução, a pressão de trabalho, o tempo de imersão, a natureza das frutas e a área de superfície (MACCARTHY, 1986;SANTOS, 2003;TEDJO et al, 2002).…”
