Abstract
The present investigation entitled “Effect of pre-treatments on storage behavior
of osmotically dehydrated pineapple (Ananas comosus L. Merr.) candy” was conducted
at Post Harvest Technology Laboratory, College of Horticulture, Banda University of
Agriculture and Technology Banda, during the year 2023. An experiment was laid out
in completely randomized design (CRD). Pre- treatments study was done on the basis of
physico-chemical parameters as well as organoleptic quality of osmotically dehydrated
pineapple candy with eight treatment combinations. The physico-chemical parameters
of osmotcally dehydrated pineapple candy viz., TSS (°Brix), reducing sugars (%), nonreducing sugars (%), total sugars (%), acidity (%), pH, ascorbic acid (mg/100g) total
phenol (%), crude protein (g/100g), crude fat (g/100g), crude fiber
(g/100g),carbohydrate(g/100g), non-enzymatic browning and organoleptic quality i.e.,
colour, flavour, texture, taste and overall acceptability were evaluated at 0,30,60 up to
90 days of storage.
Study of pre-treatment combinations with respect to physico-chemical
characteristics of osmotically dehydrated pineapple candy reflected that non-reducing
sugars (%), pH and crude protein content (g/100g), acidity (%), ascorbic acid
(mg/100g), crude fat (g/100g), crude fiber(g/100g), total phenol (%) showed an
decreasing trend while TSS (°Brix), reducing sugars (%), total sugars (%),
carbohydrate(g/100g), non-enzymatic browning were in increasing trend during 0, 30,60
and 90 days of storage. Organoleptic scores of colour, flavour, texture, taste and overall
acceptability also showed decreasing trend as storage period increased.
