Industry Color Standards OverviewUnlike some fruits, dried mango does not have one global color standard. However, major producing and importing countries such as Vietnam, Thailand, and the United States have established widely accepted guidelines.
Color standards typically define:
- Acceptable color range: From bright yellow to deep orange, with light brown sometimes allowed.
- Uniformity: Consistency within a batch is crucial.
- Defect thresholds: Limits on the percentage of brown or discolored pieces.
These standards are often used in purchase contracts and quality assurance documents. For example, a buyer might require, “90% of slices must be yellow to orange, with no more than 10% light brown.”
Color Grading Scales and ToolsIndustry professionals use several tools to check dried mango color:
- Visual comparison charts: Reference photos or color swatches showing acceptable hues.
- Munsell or Pantone color scales: Some labs use standardized color charts to assign precise color codes.
- Digital colorimeters: Advanced quality control labs may use devices to measure color values objectively.
Most wholesale deals depend on visual inspection, either in person or with high-quality photos. Clear and consistent grading criteria are important for fair and repeatable assessments.
Implementing Color Standards in Quality ControlWholesale buyers and suppliers can apply color standards at several stages:
- Pre-shipment inspection: Check random samples against reference charts.
- Arrival checks: Confirm batches match agreed color criteria before acceptance.
- Ongoing monitoring: Regularly review inventory to identify changes during storage.
It is also smart to train staff on what to look for and to record findings with photos. Some companies include color samples in contracts to prevent disputes.
For quality control, color standards should be used along with other checks, such as texture, aroma, and microbiological safety. Still, color is the fastest and most visible sign of quality.
