The bananas were washed hand-peeled and, cut into strips.(0.2 cm thickness) and washed with water. The strips were.Blanched in an aqueous solution of calcium chloride (CaCl2 at.)Different concentrations (0.25 0.5 and, 0.75 g / 100 ml distilled.Water) at 85 C for 30 s. After blanching the banana, strips were.Immediately immersed, in 0.5 1.0 or 1.5 g hydrocolloids (sodium.Alginate CMC and, pectin) / 100 ml distilled water at 37 C for 2 min.Then all pieces, were drained and dried in a hot air oven at 135 C.For 3 min to reduce the surface moisture. The frying process was.Carried out in a thermostatically temperature controlled fryer.(Model RF5S France), having a capacity of 4 L of oil. All pieces were.Fried at 150 C for 5 min in palm oil with a constant product weight.Oil volume ratio of 1: 32. The volume of oil level was checked and.Replenished after each frying. All fried samples were drained and.Cooled to room temperature before analysis.The experiment comprised three parts. Firstly the only, one best.Treatment from each group of studied hydrocolloids (alginate CMC,,And pectin), considered by the least oil uptake and the highest.Sensory scores in, all traits was selected. Secondly properties of, all.Selected three chip samples treated with possibly different,,,Concentration of CaCl2 and three different hydrocolloids and the.Control sample (banana strips blanched in water at 85 C for 30 s.And fried as previously described) were analyzed. Then the best,,Banana chip with the least oil uptake and the highest sensory.Scores in all traits was selected for surface structural study.
