What do rootless bean sprouts look like

Rootless bean sprouts usually refer to bean sprouts that have been artificially intervened to inhibit root growth. They have a thick and white appearance, no obvious root hairs, or only short root stubble. The sprout length is uniform, but there may be residual chemical odors. This type of bean sprouts may experience shedding of beans, abnormal stem swelling, or a smooth and reflective surface due to the use of plant growth regulators.

Normal bean sprouts should have slender and natural root hairs, with yellow white roots that are in proportion to the bud. Rootless bean sprouts are often artificially removed or inhibited from root growth, resulting in smooth and unbranched roots, and some may have black or brown excision marks remaining. The color of the bud is too pale or opaque, and it feels stiff and lacks elasticity, which may be related to the use of bleach or preservatives. Some unscrupulous merchants may prevent root development by adding chemicals such as rootless substances. The bean sprouts of this type are prone to turning green or black, and after soaking, oil film or flocculent sediment may appear on the water surface. Long term consumption of rootless bean sprouts containing chemical residues may cause irritation to the gastrointestinal mucosa. It is recommended to choose bean sprout products with formal testing reports, rinse repeatedly with water before consumption, and remove suspicious areas. When purchasing bean sprouts, you can observe their natural curvature and aroma. High quality bean sprouts should have a bean fragrance and natural curvature. Home grown bean sprouts can be made from seeds such as mung beans and soybeans. They can be cultivated in the dark and moisturized environment for 3-5 days to ensure complete development of the sprouts and roots. If a bean sprout is found to have a pungent odor or abnormal color, it should be immediately stopped from consumption and the problematic product should be reported to the market supervision department.
