Abstract
Background: The present study was carried out to develop a suitable formulation for value added pickle out of chicken giblet by incorporating roselle and evaluate their physico-chemical properties, sensory attributes and shelf-life qualities through microbial count, extend of proteolysis and fat rancidity after packaging in normal food grade polyethylene packaging material stored at ambient temperature. Methods: The developed value added giblet pickle was standardised with 15% rosella. The comparison was made among the samples incorporated in paste, oven dried powdered and 4% acetic acid. Result: The addition of 15% roselle in paste form increased the overall acceptability as well as the product yield. The protein content of both the treatments was found to be higher compared to the control. The pH of control (3.06±0.04) ranged to 4.25±.07 in treatment. The water activity did not differ significantly in control and treatments and the value ranged from 0.94±0.12 to 0.95±0.04. Thiobarbituric acid value (TBARS), tyrosine values and microbial count significantly (p less than 0.05) increased during storage days in all the pickle samples. However, the increase in TBARS, tyrosine values and microbial load were within the recommended limits as per FSSAI for pickled meat products. From the above study, it can be conclude that value-added giblet pickle with good nutritive value and higher acceptability can be prepared by incorporating roselle at 15% level.
