What is the typical moisture content of traded mung beans?

The standard moisture level for mung beans is 12 % as measured by internationally recognised methods. Moisture is checked during the machine‑dressing and grading process.

How are mung beans graded for purity and foreign material?

Grades are defined by purity levels (e.g., 99 % for Grade 1) and limits on inert material such as soil, stones and weeds (≤1 % for Grade 1). Grading uses air‑screen and gravity‑grading equipment to remove undesirable material.

What visual defects are inspected in mung bean grading?

Inspectors assess pod scale, seed coat damage, staining, wrinkling and dimples using photographic charts. Insect damage and mould are also recorded as defects.

What storage practices protect mung beans from contamination?

Mung beans are stored in clean, dry, ventilated silos or sealed bags, protected from pests, moisture and microbial contamination. Vertical sealable silos with good aeration are recommended.

Moisture
Water content affecting storage stability
Size grading
Proportion of beans meeting screen size thresholds
Inert/Foreign Material
Non‑bean material such as soil, stones or weed fragments
