- Maintaining quality of harvested fruit and vegetables is a challenge. The study investigated the effects of two lipid and lipid/hydrocolloid based coatings on maintaining post harvest quality of green bell peppers. Quality characteristics measured during the 4-week storage period included: respiratory rate, moisture content (weight loss), chlorophyll content, puncture force, ascorbic acid (AA) and dehydroascorbic acid (DHA)contents. No significant differences (P > 0.05) between uncoated and coated peppers were noted for respiration rate, puncture force, chlorophyll content, and AA. Significant differences (P < 0.05) were found in moisture content and DHA content in the uncoated and coated peppers. Continued research is needed in creating more sophisticated bilayer coatings to enhance product shelf-life.
