Chilean walnuts are grown in a special environment. Due to its natural barriers, Chile is considered a very rich country in terms of plant health. The Andes in the east, the Pacific Ocean in the west, the Atacama desert in the north and Antarctica in the south. All of these barriers protect agriculture from harmful and external diseases. Quality is a priority for the Chilean Walnut Commission. For this reason, since 2012, the Technical Committee works in a quality standard that wants to update industry standards in line with international requirements and processes. In 2013, the quality standard for shelled walnuts has been initiated. All Chilean walnut producers work with these standards to provide a high quality product to their customers.
