Vegetable washing is the process of removing soil, sand, plant debris and field contaminants from raw vegetables using potable water, and is a critical food safety step performed before peeling, cutting or blanching.
In trade practice
Washing is typically carried out in flotation tanks, drum washers or spray systems, with agitation to dislodge adhering soil. Water quality and renewal frequency are controlled to prevent recontamination, and potable water standards must be met as a baseline requirement under EU food hygiene legislation. QA teams monitor wash water turbidity and may test for microbial load at defined intervals. Inadequate washing is a common root cause of elevated soil or foreign-body defect counts found at intake inspection.
In a specification
A frozen vegetable specification may require the supplier to confirm that washing uses potable water meeting applicable standards and to state the washing system type, with water change frequency documented in the production process description.
