Postharvest banana grading is an essential process that categorizes bananas based on their maturity index, ensuring quality control and facilitating efficient distribution in the market. The maturity index denotes the stage of ripeness reached by the fruit and is pivotal in determining its market value and shelf life.
Banana grading criteria primarily revolve around visual color stages indicative of maturity. These stages include dark green, light green, yellow-green, yellow with green tips, pure yellow, yellow with brown spots, and dark brown spots. Each stage reflects varying degrees of ripeness, affecting taste, texture, and shelf life.
Stage 1: Dark green
Stage 2: Light green
Stage 3: Yellow-green
Stage 4: Yellow with green tips
Stage 5: Yellow
Stage 6: Yellow with brown spots
Stage 7: Dark brown spots
The grading process involves meticulous visual inspection to identify the color stage accurately. Additionally, quantification of brown spots is crucial, as excessive spotting can render the fruit unmarketable due to consumer preferences for aesthetically pleasing bananas.
Marketability assessment hinges on distinguishing between marketable and unmarketable fruit. A predetermined threshold for brown spots is established to determine the fruit's suitability for sale, ensuring only high-quality bananas reach consumers. This meticulous grading process guarantees consumer satisfaction and enhances market efficiency by aligning supply with demand.
