Abstract
The study was conducted to determine the adulteration and assessment the quality of jelly commercially available in local market of Mymensingh,
Bangladesh. A comprehensive baseline survey was completed to know consumers attitude towards jelly covering the people of different
sections of society. It was found that most of the consumers did not want to consume this product as they believed that all commercial jellies
were adulterated. Analytical works were done in laboratories of Bangladesh Agricultural University, Bangladesh Standard Testing Institute,
Bangladesh Council of Scientific and Industrial Resesarch, and SGS, Bangladesh. Physico-chemical characteristics of jelly samples were tested
in BAU laboratory. Total soluble solid content, pH, acidity, ash content of commercial brand samples were tested. Jelly samples were also analyzed
in Bangladesh Standard Testing Institute laboratory to determine acidity as citric acid (% m/m), sodium benzoate (mg/Kg), arsenic (mg/
Kg), lead (mg/Kg), copper (mg/Kg), zinc (mg/Kg), and tin (mg/Kg). From the analysis it was also clear that every commercial brand sample contained preservative to extant shelf life of the product. But it is injurious to human health to consume this type of product for long time. Increased dose of preservative was used in jellies to inhibit the growth of microorganisms particularly for yeasts and molds. According to the microbial evaluation, the samples of jelly were safe to consume. A sensory panel test was performed to judge the sensory attributes of the commercial jelly.
All the samples obtained good scores. However, the jelly samples are adulterated with artificial sweetener and preservatives.
