An article about our developed state-of-the-art analysis of the Cell Wall Calcium has been published in CAPCA Adviser magazine
We are very proud to announce that CAPCA Adviser magazine has published an article about a new analysis developed by AGQ Labs that helps to control the Quality of the Fruit analyzing the Cell Wall Calcium.
Up until now, the majority of the tests conducted had estimated cell wall calcium indirectly, as the difference between total calcium and soluble calcium. Such a procedure is inexact, it overestimates the bound fraction by adding the insoluble and residual fractions, which are sometimes greater than the bound fraction. Thus, on 2015, the R&D Department of the Agronomic area of AGQ Labs started working on designing a specific method for analysis of both cell wall calcium and total calcium, with detection limits lower than those used on the leaf. This testing has been conducted in parallel at our laboratories in Spain and Chile. We have studied the evolution of calcium fractions throughout the ripening period of the fruits (e.g. tomatoes), comparing fruits that do and do not experience specific alterations (e.g. bitter pit in apples or cracking in peaches). We have also conducted tests on blueberries and avocados.
This method has been fine-tuned by our laboratories, by conducting specific extractions, so that, using plasma emission spectrophotometry (ICP) the various calcium fractions can be analyzed. After many months of work and testing, we can state that the analysis is validated.
As a result of these tests, we can conclude that cell wall calcium is a diagnostic tool for evaluating quality parameters related to the appearance and market life of the product. We have also seen that, in certain matrices, total calcium, with quantification limits adapted to the fruit, is also a very reliable marker for assessing a number of concrete alterations.

Innovation and conservation are vital to California’s economy. Nowhere is this more important than in the state’s agricultural and horticultural industries, which rely on the latest science and research to help manage diverse pest and disease threats.
Since 1972, California has demonstrated its commitment to protecting the state’s natural resources and communities by maintaining a formal licensing program for pest control advisers (PCAs). These individuals work with growers and landowners to enhance plant health, increase biodiversity and reduce agricultural losses on millions of acres of managed land. Their expertise helps California deliver the safest food supply in the world and ensures that the state’s parks and recreational spaces are free from invasive pests, weeds and diseases.
CAPCA helps the state’s PCAs excel at their jobs by delivering the latest industry trends, tracking hours for continuing education and pursuing advocacy efforts in Sacramento. The organization is a vital resource to keep California at the cutting edge of responsible pest control strategies.
California is at the center of responsible land management. As technology continues to improve our ability to target individual pests and diseases, PCAs will continue to support the health of California’s citizens, landscapes, water resources and wildlife into the 21st century. CAPCA is dedicated to supporting the next wave of innovation.
