We insist on supporting local farmers and using domestic soybeans. The market is filled with soybean products that consist of all kinds of chemical additives, so it is most difficult to make pure and healthy soybean products. HIDEKAWA checks every production detail carefully. We insist on screening and picking out soybeans manually to eliminate impurities from affecting the quality of our soy milk. We bathe cleaned soybeans in pure water overnight before grinding and steaming. During the process, no antifoaming agents or thickeners are added. After the concentration is tested to standard, it is filtered once by machine and once by hand to produce the Grade 10 soy milk that is the most natural and pure Taiwanese flavor.
