Abstract:
The present investigation entitled “Standardization of blanching and sulphitation techniqueon physical parameters for dehydration of banana pseudostem central core for powder making using cabinet dryer” was carried with 16 treatments were fixed for preparation of powder using different combinations including pre-treatment of blanching (B₁-0 min., B₂-2 min., B₃-4 min. and B₄-6 min.) and sulphitation (S₁-0.0% KMS, S₂-0.1% KMS, S₃-0.2% KMS and S₄-0.3% KMS). The prepared blended powder was stored at room temperature for up to 6 months (0, 3 and 6 months) in 100 g aluminum laminated pouches. The results were statistically analyzed using a completely randomized design with factorial concept. The experiment revealed that maximum recovery (3.82%), minimum drying time (5.02 hr) and (5.14 hr) and highest total drying rate (114.28g/hr) and (112.67 g/hr) found without blanching (B₁) and sulphitation (S₁) respectively. While the interaction of B₁S₃ (without blanching and 0.2% KMS treatment) found maximum recovery (3.85%), minimum drying time (5.01 hr) and total drying rate (114.28 g/hr). The highest bulk density (0.649 gcm^-3), (0.597 gcm^-3) and (0.693 gcm^-3), maximum water holding capacity (548.98%), (543.74%) and (564.99%) although maximum oil absorption capacity (231.01%), (226.92%) and (232.60%) was found in 6 minutes blanching (B₄), 0.3 percent KMS (S₄) and P₁B₄S₄ (initial month of storage with 4 minutes blanching and 0.3% KMS treatment) respectively.
