Lotus root starch, a traditional nourishing food, has been consumed in China for thousands of years. Its origins can be traced back to the Tang Dynasty. According to the "Compendium of Materia Medica for Dietary Therapy," lotus root was already ground into powder for consumption. By the Song Dynasty, with advances in agricultural technology and the widespread cultivation of lotus root, lotus root starch gradually evolved from a folk remedy to a royal tribute. "Dongjing Menghualu" contains detailed descriptions of lotus root starch soup sold in teahouses in Bianliang, demonstrating its popularity during the Northern Song Dynasty.
The Ming and Qing dynasties were crucial periods for the development of lotus root starch processing. In the Ming Dynasty, Li Shizhen systematically documented the medicinal benefits of lotus root starch in his "Compendium of Materia Medica," describing it as "tonifying the body and nourishing the spirit, increasing energy and strength, and curing all ailments." The imperial kitchens of the Qing Dynasty advanced lotus root starch production to its limits, developing the traditional "three-steaming and three-drying" technique, achieving crystal-clear, easily digestible lotus root starch. Due to their abundant lotus roots, Suzhou, Hangzhou, and other regions gradually developed unique schools of lotus root starch production. West Lake lotus root starch was even listed as a tribute during the Qianlong reign.
Traditional lotus root starch production requires over ten steps, including lotus root selection, pulping, settling, and airing. High-quality lotus root starch is made from old lotus roots harvested around the winter solstice. After soaking in clean water to remove astringency, it is repeatedly ground using a stone mill to obtain a pulp, which is then filtered and settled multiple times to obtain the purest lotus root starch. This ancient method maximizes the preservation of minerals such as iron and calcium, as well as active ingredients such as mucin, found in the lotus root. In modern times, advances in food industry technology have led to the emergence of new products such as instant lotus root starch, but traditional handmade lotus root starch remains highly regarded for its pure quality.
As a vital component of Chinese culinary culture, lotus root starch not only embodies the agricultural wisdom of the Jiangnan water towns but also embodies the Chinese philosophy of health preservation, emphasizing the common origins of medicine and food. Today, this traditional food has spread to Southeast Asia, Europe, and the United States, becoming a key symbol of Chinese culinary culture. In the fast-paced modern life, lotus root starch continues to nourish people's health and life taste with its convenient nutritional supplement and profound cultural heritage.
