Characterization and Evaluation of Physicochemical and Sensory Acceptability of Ice Creams Incorporated With Processed Ginger (Published)

The study was undertaken to develop different forms of the ginger ice cream using 5% ginger juice, 5% ginger paste and 5% ginger syrup. These ice cream samples were analyzed for physicochemical, microbial and sensory properties during 28 days of frozen storage at -20 0C. Incorporation of the juice, syrup and paste in ice cream reduced total solids, fat, acidity and total soluble solid, and increased antioxidant activity. Ash content increased with the ginger paste, whereas it decreased with the ginger juice and syrup. First dripping time amplified and melting rate declined with all the ginger preparations. And also textural properties increased and microbial activity decreased with ginger added ice creams. During storage, the total solid, ash, fat, total soluble solid content, dripping time and textural properties were significantly (p<0.05) increased. pH content, antioxidant activity and melting rate were significantly (p<0.05) decreased with the storage period. Organoleptic properties were evaluated though the panel of 30 members. As a results of organoleptic characteristics revealed that, 5% of ginger syrup incorporated ice cream had the highest mean score of overall quality of all sensorial properties namely, colour, taste and overall acceptability

INFLUENCE OF CALCIUM SOURCES AND CONCENTRATION ON THE STORAGE PERFORMANCE OF STRAWBERRY FRUIT (Review Completed - Accepted)

The Influence of calcium sources and concentration on the storage performance of strawberry fruit was determined by harvesting the fruits at red stage and treatment with calcium nitrate, calcium gluconate and calcium chloride at 0% (distilled water), 0.5, 1.0 and 1.5% calcium solutions by dipping for 30 seconds. The calcium sources, concentration and the interaction of calcium sources and concentration significantly affected the storage performance of strawberry fruit. While all the three sources and concentrations were effective in decreasing the storage associated changes i.e. weight loss, decline in marketable fruits, loss of organoleptic quality, increase in TSS, decline in reducing sugars, total sugars and acidity and increase in Sugar/ Acid ratio in strawberry fruit, thus extended the shelf life, Calcium gluconate and calcium concentration of 1.5% was more effective. Treatment of strawberry fruit with 1.5% calcium from Calcium gluconate source resulted in the highest number of marketable fruit (100%), extended shelf life (10 days) total soluble solid (7.80%) with the minimum weight loss (5.45%). Ascorbic acid content was the highest (35.35 mg/100 g) in fruits treated with the calcium nitrate at 1.0% calcium concentration but was at par with Calcium gluconate. It can be concluded that calcium gluconate at 1.5% concentration is an effective calcium treatment to retain the quality and extend the shelf life of strawberry fruit.
