Effect of calcium salts on the texture, structure and sensory acceptance of osmotically dehydrated guavas

Abstract: The effect of additives, calcium chloride and calcium lactate (5-25 g kg −1 ), on the osmotic dehydration of guavas with sucrose solutions was studied, aiming at the structural preservation of processed fruits. The osmotic process was evaluated from the reduction in weight of the guavas, water loss and solids gain, and the samples were analyzed with respect to calcium content, texture (stress and strain at failure, relaxation time and residual stress), structure by light microscopy and sensory acceptance.

“…Microscopic studies have revealed an enhancement of cell cohesion and turgidity and an increase in cell wall integrity due to the application of calcium salts to osmotically dehydrated fruits, resulting in products with better texture characteristics (Mastrá ngelo et al, 2000;Pereira, Carmello-Guerreiro, Bolini, Cunha, & Hubinger, 2007). The action of calcium on the cellular structure can be explained by its effect on the pectin matrix present in the cell wall of plant tissues.…”

“…As amostras desidratadas (série alcoólica-etílica) foram infiltradas em resina hidroxitil metacrilato (HistoResin, Leica Microsystems-Jung, Heidelberger, Alemanha), seccionadas a 8 µm de espessura, utilizando micrótomo rotativo (820 Spencer Microtome, American Optical Corporation, Nova York, EUA), montadas em lâminas e coradas com azul de toluidina a 0,05% em tampão acetato (pH 4,7). Finalmente, as amostras foram observadas ao microscópio óptico Olympus BX51 (Olympus Optical CO., Tóquio, Japão), de acordo com a seqüência experimental descrita por Pereira et al (2007).…”

“…Além disso, verificou-se que quanto maior a concentração de lactato de cálcio adicionada na solução de sacarose, maior a tensão na ruptura das amostras. Tal comportamento também foi observado por Pereira et al (2007) durante a desidratação osmótica de metades de goiaba, empregando-se soluções de sacarose a 60°Brix e lactato de cálcio (0-2,0%). Por outro lado, Castelló et al (2009) constataram uma redução da tensão nas fatias de maçãs desidratadas osmoticamente com solução de glicose e 2% de lactato de cálcio.…”
