Comparative Study Of The Shelf-Stability Of Kolanut Softdrink Preserved With Citric Acid, Sodium Benzoate, Sodium Metabisulphite And Benzoic Acid
ABSTRACT
Fresh kolanut (Cola nitida) was used
to produce cola soft drink. Proximate analysis was carried out to determine
moisture, crude fibre, ash, caffeine, carbohydrate and lipid content on both
fresh nuts and the finished product (Cola soft drink). Physico-chemical and
sensory evaluation were carried out on the drink with a control sample (Fanta
orange). Also, microbial analysis was carried out on the drinks to determine
the efficiency of citric acid, sodium benzoate, sodium metabisuiphite and
benzoic acid on the kola soft drink. The result showed that the fresh nut
contained 9.78% moisture, 2.35% ash, 0.90% lipid 8.75% protein, 1.45% caffeine
and 7.03% crude fibre. The control sample (fanta orange) rated highest in
nutritional composition and sample preserved with benzoic acid was generally
acceptable to the panelist. Physico-chemical analysis carried out on the
preserved drink was similar to that of the control sample. The drink was fit
for consumption for one month of storage at room temperature (26°C). After one
month of storage, Bacillus mecerans and Bacillus cereus were both identified in
all the preserved kola drink as spoilage organisms.
