大米分析

大米及其多种用途的质量控制解决方案

大米是全球人类和动物饮食中的重要谷物。因此，从稻田开始，贯穿碾磨、储存直至消费者手中的严格质量控制流程，对于满足全球需求至关重要。所有大米品种及其副产品均具有可测量的质量参数，借助 KPM 的技术即可实现有效管控。

用于食品生产或牲畜饲料的大米，其等级由美国农业部 (USDA)及其他机构根据特定的可测量质量参数进行评定。借助近红外光谱 (NIR) 技术，只需极少的样品制备，即可快速轻松地测量其中大多数参数。


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.

作为一种半水生植物，水稻最适宜在水分充足且灌溉条件稳定的土壤中生长。除了充足的水分外，理想的收成还需要其他多种土壤参数——所有这些参数均可借助 KPM 的土壤分析解决方案进行高效检测。


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.
