摘要
为了更好地利用谷物,当今世界越来越重视利用绿色技术对谷物进行改良。使用频率为 20 kHz、功率为 100 & 200 W 的探头超声波,以 1:5 的比例(w/v)处理棕顶小米,每次处理间隔 5 分钟,持续 5-35 分钟。通过扫描电镜观察到样品表面形态的变化,这对吸水率有积极影响,吸水率从 164% 提高到 179.2%;因此,处理后样品的蒸煮时间从 18.8 分钟缩短到 7.9 分钟。热性能和糊化性能表明,处理过的样品温度降低,粘度增加,从 74°C 降至 70.7°C,4.23Pa.s 升至 11.50Pa.s。在所有试验中,200 W 20 min 是棕顶小米的最佳蒸煮条件,蒸煮时间较短,相对结晶度较低。
Evaluation of quality characteristics of ultrasound–treated browntop millet grains
Modification of grains using green technologies receiving more attention in today's world for better utilization. Browntop millet was treated at a frequency of 20 kHz using probe ultrasound at 100 & 200 W for 5–35 min of 5 min intervals between the treatment at the ratio of 1:5 (w/v). The impact of treatment on grains was evaluated utilizing several parameters, such as relative crystallinity (RC) of the treated samples, which decreased from 59.78 % to 34.41 % at 100 W and 22.84 % at 200 W. Change in the surface morphology of the samples was observed by SEM which had a positive impact on water absorption as it increased from 164% to 179.2%; thus, the cooking time in treated samples is reduced from 18.8 to 7.9 min. Thermal and pasting properties showed a decrease in temperature and increase in viscosity of the treated samples from 74 to 70.7 °C, and 4.23 Pa.s to 11.50 Pa.s this shows that grains with lesser gelatinized temperature tends to cook fast and has the softer texture, thus sonicated samples have better eating quality. Among all the trials 200 W 20 min were the optimal conditions for the browntop millet with lesser cooking time, relative crystallinity.
