Abstract
Various concentration of aloe vera based coating formulation (25%, 50%, 75%, and
100%) was applied on fresh whole guava by dipping method. The guava was stored at a
refrigerated condition (40C) and weight loss, color, firmness, vitamin C, total phenol and
pH change were observed in this research. A significant effect of aloe vera coating was
found over the storage period. Aloe vera treatment lowered the weight loss, also retard the
texture and color than the control sample throughout 28 days of storage periods. Vitamin
C and total phenol content seemed highest value 141.4 mg/100g and 219.6 mg GAE/100g
respectively in 100% aloe vera coated sample after 28 days of storage than the control.
Among 25%, 50%, 75%, and 100% aloe vera based coating sample, 100% aloe vera was
best coating material to prevent the physical changes in fresh guava.
