Pea vining is the mechanical separation of green peas from their pods and haulm, carried out in the field or at a nearby station immediately after harvest, and is critical because pea quality degrades rapidly once pods are cut.
In trade practice
Mobile or static vining machines thresh the crop and separate peas from pods, stems and leaves within hours of cutting. Processors record time-from-field to blancher because sugar-to-starch conversion accelerates at ambient temperature. Intake teams check tenderometer or alcohol-insoluble solids readings to confirm peas were vined and chilled promptly. Delays between vining and blanching are a common cause of starchy, off-grade product.
In a specification
A frozen pea specification typically states a maximum time between vining and blanching and requires tenderometer or alcohol-insoluble solids values measured at intake to confirm maturity at the point of vining.
