Horticultural crop variety identification:

• Banarasi, Kanchan (NA-4), Krishna (NA-5), Narendra Aonla-6 (NA-6), and Narendra Aonla-7 (NA-7) are well-known commercial cultivars of Aonla (Phyllanthus emblica).
• Sultana (Thompson Seedless) is a world-famous white, seedless grape (Vitis vinifera) variety widely used for raisin production, not an aonla variety.

Food preservation standard recipe for preserves (Murabba):

• In commercial and traditional preserve/murabba preparation from firm fruits like aonla, apple, and bel, the standard recipe employs an equal proportion of prepared fruit to sugar, i.e., $1 : 1$ by weight ($1\text{ kg}$ sugar per $1\text{ kg}$ pricked and blanched fruit).
• The sugar is infused in gradual stages until the final syrup reaches a minimum TSS of $68 - 70^\circ\text{Brix}$ and the fruit becomes translucent.

Processing protocol for bleached dry ginger (limed ginger):

• In the manufacture of bleached dry ginger, cleaned and scraped rhizomes are repeatedly dipped in a $2\%$ milk of lime suspension ($Ca(OH)_2$) and sun-dried.
• The lime coating imparts a desirable white bleached appearance, neutralizes surface acids, and protects against insect infestation and mold growth during storage.
