Abstract:
The study entitled Effect of beeswax and hydroxypropyl methylcellulose coatings on Physical paramaters of guava cv. Shweta under ambient conditions. The winter fruits of guava cv. Shweta coated with hydroxypropyl methyl cellulose (5%, 10%), beeswax (3%, 6%, 9%) and their combinations, packed in CFB boxes and kept at room temperature in month of December. The uncoated fruits (T₁₂-control) packed in CFB boxes were also included in experiment for comparison. The guava fruits coated with HPMC 10% + beeswax 9% had recorded significantly lower mean physiological loss in weight (3.13%) as compared to control (PLW 6.16%). Likewise, HPMC 10% + beeswax 9% had exhibited highest mean fruit firmness (18.78 Ibf) as compared to others treatments. After 7-days of ambient storage, significantly higher organoleptic rating (8.35) was observed in treatment (T₁₁) in which HPMC 10% + beeswax 9%, coatings were applied as compared to control. The untreated fruits had the highest rate of deterioration (spoilage %), whereas all coatings applied fruits had significantly lower spoilage with minimum mean spoilage (2.28%) under ambient storage conditions. Hence, the study revealed that the fruits of winter guava cv. Shweta applied with HPMC 10% + beeswax 9% coatings can be stored for 7-9 days under ambient conditions.
