Optical properties of ensete starch films.
Sample | l | a | b | DE | Tf (%) |
---|---|---|---|---|---|
E1.5 | 39.01 ± 0.39 | -0.02 ± 0.02 | 0.86 ± 0.31 | 39.02 ± 0.38 | 78.17b ± 2.87 |
E2.0 | 42.92 ± 1.74 | 0.02 ± 0.02 | 1.02 ± 0.28 | 4293 ± 1.75 | 57.50a ± 4.83 |
E2.5 | 43.86 ± 6.34 | 0.40 ± 0.04 | 0.73 ± 0.49 | 43.87 ± 6.34 | 51.65a ± 2.28 |
Mean ± SD. Mean with different superscript letters along a column are significantly different (p < 0.05). Except Tf which was repeated thrice, other experiments were done in duplicate. One-way analysis of variance and Duncan Multiple Range Test (DMRT) in SPSS (15.0) environment were used to obtain and separate means at p ≤ 0.05, respectively.
E1.5: Film containing 1.5 mL glycerol; E2.0: Film containing 2.0 mL glycerol; E2.5: Film containing 2.5 mL glycerol; l: Lightness index; a: Red-green index; b: Yellow-blue index; DE: Color difference; Tf: Film transparency.
