Rice Analysis | KPM Analytics

Moisture and Compositional Analysis

Rice used in food production or to feed livestock receive their grades from the USDA and other entities based on certain measurable quality parameters. Most of these parameters can be measured quickly and easily with the help of near-infrared spectroscopy (NIR) technology with minimal sample preparation.

What's Analyzed


Parameter	Why It's Analyzed	When It's Analyzed
Moisture	Excessive moisture can lead to sticky product, which may also be more susceptible to spoilage. Excessive moisture can lead to sticky product, which may also be more susceptible to spoilage.	Drying and/or milling process Assessing outgoing product
Protein	While rice has a lower protein content than other whole grains, it contributes to reduced cholesterol in human diets. While rice has a lower protein content than other whole grains, it contributes to reduced cholesterol in human diets.	Drying and/or milling process Assessing outgoing product
Starch	Starch relates to the cooking properties of rice.	Drying and/or milling process Assessing outgoing product
Test Weight	Test weight is a volumetric measurement that is a common quality indicator for rice grading processes.	Drying and/or milling process Assessing outgoing product

Functional and Rheological Analysis

Rice is a popular gluten-free option that is used in a variety of baked goods such as bread, muffins, granola bars, cookies, and others. Rice is also commonly processed into other food products, including noodles, spring roll wrappers, and others, which also originate from a rice milling process.

Soil Nutrient Analysis

As a partially aquatic plant, rice grows best in high-moisture soils where consistent irrigation is available. Along with adequate moisture, several other soil parameters are also necessary for an ideal harvest – all of which can be analyzed efficiently with the help of soil analysis solutions from KPM.

Analytes Measured


Parameter	Why It's Analyzed
Nitrogen-based nutrients (Ammonia, Urea, TKN, Nitrate, Nitrite)	Nitrogen is the most important soil nutrient for maximizing rice yield. Growers can apply nitrogen in the form of ammonium fertilizers as needed. Urea and TKN content also have a role in animal feed quality.
Phosphorus-Based Nutrients (TP, o-Phosphate, Phosphate)	Phosphorus is applied to the soil via fertilizer throughout the growing season, especially if routine flooding or draining cycles may affect the availability of Phosphorus over time.
Potassium	Potassium may need to be added via fertilizer at different stages of the growing season to help rice plants ward off crop disease.
Other Compounds in Crop Production	Sulfur, boron, iron, magnesium, zinc, and other minerals all have a role in rice crop production.
