Global dietary calcium deficiency affects 30% of the population. In low- and middle-income countries, staple crops lack calcium after processing, worsening this gap. Serious outcomes include osteoporosis, impaired growth in children, weakened bone structure, and increased fracture risk. Biofortification of staple crops elevates calcium concentration, directly targeting entire populations.

Challenges in Screening Calcium Content in Food Crops
Traditional calcium quantification—via atomic absorption spectroscopy or wet chemistry—demands time-intensive procedures, skilled labor, and generates chemical waste. These methods process under 50 samples per day, limiting large breeding programs. High-throughput energy dispersive x-ray fluorescence spectroscopy (ED-XRF) solutions are required for rapid, accurate calcium screening in solids. ED-XRF enables precision measurement in harvested grains or ground tissues, supporting large-scale biofortification breeding and regulatory compliance. Portable XRF spectrometers, such as Lonnmeter, streamline workflows by minimizing sample preparation and labor, facilitating timely decision-making in breeding pipelines.
Key Advantages of Handheld and Portable ED-XRF Analyzers
Handheld energy dispersive x-ray fluorescence spectrometers deliver rapid, on-site elemental analysis with minimal setup. Portable x-ray fluorescence spectrometers allow cost-efficient, high-throughput screening. ED-XRF analysis requires limited training, supporting agricultural research on calcium content in foods and techniques for crop biofortification.
Accelerating Biofortification Breeding with X-ray Fluorescence Spectrometry
Why XRF Surpasses Traditional Screening Techniques
Energy dispersive X-ray fluorescence spectroscopy enables non-destructive, rapid screening of calcium content in staple crops. Sample throughput can exceed 500 measurements per day with a handheld energy dispersive x-ray fluorescence spectrometer, compared to fewer than 50 samples using ICP-MS or AAS.
XRF requires minimal sample preparation, avoiding acid digestion and hazardous waste generation. Operational simplicity enables less labor-intensive screening, making it accessible for breeding stations and field research. Multiplexed elemental detection permits screening for macro- and micronutrients simultaneously, offering major advantages for biofortification of staple crops.

Targeting the Calcium Content of Foods Through Staple Crop Innovation
X-ray fluorescence (XRF) analysis empowers breeders to identify, validate, and advance high-calcium genotypes. Portable x-ray fluorescence spectrometer technology provides precise quantification of calcium content in grains and seed samples directly in the field, eliminating laboratory bottlenecks. The Lonnmeter handheld XRF analyzer, optimized for agricultural materials (Mg to U), delivers superior sensitivity for measuring calcium down to low ppm levels in solid samples. For example, wheat and maize breeding programs routinely employ energy dispersive x-ray fluorescence applications to quantify calcium content in hundreds of lines. This robust technique streamlines selection cycles, accelerates release of nutritionally enhanced staple crops, and underpins techniques for crop biofortification.
