Trimming is the removal of inedible, damaged or non-conforming parts of a vegetable or fruit, such as outer leaves, root ends, stems and blemishes, and directly affects both product quality and processing yield.
In trade practice
Trimming may be carried out manually by line operators or mechanically using cutting and sorting equipment, depending on the product and volume. Trimming standards are defined in product specifications and communicated to production teams through work instructions, with supervisors checking conformance during production runs. Over-trimming reduces yield and increases raw material cost, while under-trimming leads to defect failures at buyer intake. Trimming performance is often reviewed during supplier audits by examining batch records and conducting line observations.
In a specification
A product specification should define which parts must be removed, acceptable residual defect levels after trimming, and whether trimming is manual, mechanical or a combination, so that intake inspection criteria are unambiguous.
