Abstract: (703 Views)
Tomatoes are known as one of the most consumed food crops among the common vegetables in the world. Since tomatoes are highly perishable, there are many problems in their transportation, storage and marketing. This research was conducted with the aim of investigating the effect of carrageenan and spermidine treatments on the physiological and biochemical properties of Lycopersicon esculentum cv. Teena. This factorial experiment was performed in a completely randomized design, at two storage temperatures 12 and 27 ºC, with three repetitions. Ripe green fruits were treated with concentrations of 0, 2 and 4 ppt λ-carrageenan and 0, 1 and 2 mM spermidine by immersion and for 10 minutes. The storage period was considered as two months. By measuring some characteristics during storage, it was found that the highest amount of titratable acidity was obtained by treating the fruits with 1 ppt carrageenan at a storage temperature of 12 ºC, and the highest firmness of the fruit tissue, ascorbic acid, lycopene and the lowest amount of total dissolved solids, percentage of fruit weight loss, polygalactronase and pectin methylesterase activity in fruits treated with λ-carrageenan 4 ppt at the temperature of 12 °C. The results of this experiment indicate that the carrageenan solution of 4 ppt and 12 °C can be introduced as a useful treatment to maintain the quality of the stored tomato fruits.
