The study on "Quality evaluation of Indian gooseberry (Emblica officinalis Gaertn.) products" was undertaken to evaluate the different Indian gooseberry products for their acceptability, chemical composition and storage stability. Six best accepted Indian gooseberry products viz., tutifruiti, preserve, salad, samosa, jelly and candy were selected from a total of eighteen Indian gooseberry products by conducting a preliminary acceptability study using score card in 120 individuals . • The fresh, sugar treated and salt treated Indian gooseberry and the selected products were analysed forchemical constituents like moisture, vitamin C, tannin, sugar, fibre and iron and found that the salt treated gooseberry had a lower vitamin C, retention when compared to the sugar treated gooseberry. Among the products, the maximum vitamin C was observed in salad and the least in samosa. The maximum moisture and fibre content was observed in salad, sugar content in jelly, tannin content in candy and iron content in preserve. The yield and cost ratio of the selected products was computed. Based on the ratio candy was found to be the most economical product. Among the six Indian gooseberry products selected for the storage study, two products viz., samosa and salad were found to be highly perishable and were deleted from the detailed storage study. The remaining four products viz., candy, preserve, tutifruiti and jelly were stored under ambient and refrigerated conditions in glass bottle, polypropylene bottle and polypropylene bag for a period of six months and their chemical constituents, organoleptic qualities and microbial load were analysed at monthly intervals. The chemical constituents viz., moisture, vitamin C, tannin, sugar, fibre and iron were analysed. All the chemical constituents were found to reduce with the storage period except sugar which showed an increase with the storage period. All the products were found to retain better vitamin C when stored under refrigerated condition. Compared to the products stored in ambient condition the refrigerated products were found to contain higher tannin and lower fibre content. No significant variation in iron retention was t>bserved with storage condition. Refrigerated storage condition was found to be ideal for better retention of nutrients. With regard to packaging systems all the products exhibited higher vitamin C retention when stored in glass bottle and the least when stored in polypropylene bag. Sugar, fibre and iron content of the products were also found to be more when stored in glass bottle when compared to the products stored in , polypropylene bag. Thus glass bottle was found to be the ideal packaging system compared to polypropylene bottle and polypropylene bag with regard to chemical constituents. The organoleptic quality attributes VIZ., appearance, colour, flavour, texture and taste were evaluated in all the products stored under ambient and refrigerated condition in glass bottle, polypropylene bottle and polypropylene bag at monthly intervals for a period of six months. The evaluation revealed that with regard to all the quality criteria analysed the preserve and tutifruiti were best accepted by the 6th month under both storage condition. The ideal storage period for candy and jelly under both ambient and refrigerated condition was for three months. With regard to the quality parameters like the appearance, colour, flavour and taste all the products exhibited the maximum acceptability when stored in glass bottle and the least acceptability was for the products in polypropylene bag except for texture. Thus the glass bottle was found to be the ideal packaging system for Indian gooseberry products in terms of organoleptic qualities also. The results of the above study revealed that compared to other processed fruit products Indian gooseberry products have better nutritive value. It The products were found to retain a significant amount of vitamin C even after storage. The maximum retention of vitamin C was found in candy (38%) stored in glass bottle under refrigerated condition. The glass bottle storage was found to be ideal for higher retention of chemical constituents and for best acceptability. The study highlighted the significance of processed amla products as a solution for the increased consumer demand for nutritious, delicately flavoured and economical fruit products all throughout the year. |
