Explain by giving two examples, how biotechnology has helped the Indian farmers in processing their perishable crops. (Answer in 150 words)
In short
Biotechnology helps Indian farmers process perishable crops by converting them into stable, higher-value products through microbial fermentation and enzyme technology. Nashik's grape wineries and pectinase-based mango pulp units in Chittoor show how microbes and enzymes cut post-harvest loss and steady incomes.

Grape surplus to wine
Nashik's wineries ferment surplus and table-grade grapes with selected yeast strains, giving growers an assured buyer when fresh prices crash.
Cashew apple to feni
In Goa, the highly perishable cashew apple is fermented and distilled into GI-tagged feni instead of being discarded.
Higher pulp yield
Pectinase from the fungus Aspergillus niger breaks down pectin, raising pulp recovery in the mango units of Chittoor and Krishnagiri.
Longer shelf life
Enzyme-clarified pulp is aseptically packed and keeps for months, so farmers sell beyond the short mango season.
