However, there is insignificant difference in overall acceptability of the two samples OPJ and LPJ while those jam types differed significantly from commercial pectin jam.
However, all jam products were accepted by the panelists who preferred jam produced using commercial pectin. Table 4. Conclusions It could be concluded that both lemon and orange can be used in making jam. The low gel strength of the jam can be improved by the addition of pectin during processing to attain the commercially acceptable gel strength or a combination of fruits rich in pectin can be used to make up for the deficiency.
The combination with other fruits could serve to improve the flavour and the colour. It is highly recommended to encourage production of jam using local raw materials like sugar beet at household level and strict conditions must be available while making jam at home. More research is recommended on the use of natural pectin from local fruits for the production of jams.

Taking this into consideration, we have used organic clay as mineral acid instead of the concentrated In food application the pectin is used in dosage between acids.
Pectin is gelatinized in the presence of saccharine and small II. An orange specifically, the sweet orange grade. Natural red clay was collected near panvel region.
Pectin is widely Black and white clay was collected near satara region. The distributed in the cell walls of the roots, stems, leaves and raw material used for extraction of pectin is orange peel. As orange waste, pectin is Orange peels [10] were collected from juice house. Centrifuge model used was Eppendorf R.
