The aim of this work was to investigate the impact of almond gum as coating agent to decrease the oil
absorption and to increase the moisture content of fried potato chips meaning a BoxeBehnken design.
The studied parameters were: almond gum concentration (0e20 g/L), frying time (30e120 s) and frying
temperature (160e190 C). Results showed that the increase of almond gum concentration up to 20 g/L
decreased the oil uptake of potato chips by 34% and increased the moisture by 29.5%. Optimal coating
and frying conditions found with RSM were thus achieved with 20 g/L aqueous almond gum, 75 s frying
time at 160 C frying temperature. Additionally, the study of sensorial analysis (color, appearance,
crispiness, taste, odor, appetence) showed that the chips coated with almond gum have an overall
acceptability better than the uncoated potato chips, and the ones coated with arabic gum. The textural
analysis of potato chips showed that the hardness (rigidity) decreased significantly by coating either with
almond gum or arabic gum. The results obtained through this work showed that coating with almond
gum improves the sensorial and nutritional qualities of potato chips
