Companies in Lam Dong Province have established a one-stop production chain encompassing cultivation, processing, and export, with products finding their way to the Japanese market. Da Lat Food Processing Company exports approximately 3,000 tons of sweet potatoes to Japan annually, taking advantage of the market's high quality demands and higher export prices. To meet these standards, companies invest in advanced cultivation technology and strict quality control measures, resulting in superior yields and increased processing recovery rates.
