Standardization of blanching and sulphitation technique on physico-chemical parameters for dehydration of banana pseudo stem central core for powder making using cabinet dryer

Abstract

The experiment was conducted to evaluate the performance of “Standardization of blanching and sulphitation technique on physico-chemical parameters for dehydration of banana pseudostem central core for powder making using cabinet dryer” with 16 treatments were fixed 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. Results indicated that maximum potassium content (4964.25 mg/100g), (3690.77 mg/100g) found in B1 and S3, maximum iron content of (13.31 mg/g) and (11.13 mg/g) found in treatment B1 and S2 respectively. While highest TSS (2.83 ºB), (2.30 ºB), crude fiber (15.51%), (14.05%) and ash content (28.76%), (25.48%) observed in treatment B1 and S1 respectively. The highest SO2 content (72.18 ppm), (40.58 ppm) were found in B4 and S4 respectively although, highest L* value of (79.42), (71.32) were found in treatment B3 and S4 respectively. Also, the interaction of blanching-sulphitation and storage maximum potassium content (5216.00 mg/100g), iron content (13.67 mg/g) were recorded in P1B1S3 and highest TSS (2.90 ºB) in P3B1S3 while crude fiber (15.76%) and ash content (29.30%) was observed in P1B1S1 although highest SO2 content in P1B4S4.
