Grain & Produce Quality Testing

Grading crops by measurable quality

Grain and produce quality equipment turns harvest into measurable grades. Grain silos, flour mills, food control authorities, plant breeders, agricultural universities and fruit packers use it to measure moisture before storage, determine protein by Kjeldahl or near-infrared analysis, extract fat and crude fibre, assess milling yield with laboratory huskers and polishers, and test flour by falling number, gluten, farinograph and extensograph. Refractometers and firmness testers judge fruit ripeness and harvest timing, while dedicated meters check moisture in hay, tobacco and wood. ASFAN supplies, installs and supports this equipment and helps specify complete cereal and food quality laboratories.

ASFAN supplies and supports grain and produce quality equipment for mills, silos, food laboratories and research centres across Qatar.

Safe storage and fair trade

Accurate moisture and volume-weight readings at intake protect stored grain from mould and heating, and give buyers and sellers an objective basis for price.

Nutritional composition

Kjeldahl nitrogen, Soxhlet fat, crude fibre and near-infrared analysis quantify protein, oil and fibre for breeding selection, feed formulation and food labelling.

Milling and baking performance

Falling number, gluten, farinograph and extensograph tests predict how wheat and flour will behave in the mill and bakery, guiding blending and variety choice.

Harvest timing for fruit

Brix refractometers and firmness penetrometers show sugar content and flesh firmness, helping growers and packers pick fruit at the right stage for market or storage.

Frequently Asked Questions

Should we use NIR analysis or traditional chemistry?

Near-infrared analysis is fast, needs no chemicals and suits routine screening. Kjeldahl, Soxhlet and fibre methods remain the reference methods and are needed to calibrate NIR results, so most quality laboratories keep both.

Which moisture meter suits our application?

Portable and pin-type meters suit quick checks in stores and fields, cup-type and benchtop testers suit intake laboratories, and halogen analysers provide reference moisture values. Separate meters cover hay, tobacco, wood and building materials.

Why are laboratory huskers and polishers needed?

They process small rice samples the way a commercial mill would, so laboratories can measure brown rice yield, head rice ratio and whiteness when evaluating varieties, purchases or storage conditions.
