Conteúdo: |
After the grinding stage of yam tubers, ultrasonic treatment (UT) is comparedto traditional starch extraction. Different sonication conditions of amplitude(12, 40, and 68%) and time (3, 6, and 9 min) are evaluated along two othertreatments: a control (0% amplitude) and 70% amplitude for 15 min, in order tocompare the traditional extraction method and extreme ultrasonic conditions.Extraction yield, centesimal composition, color instrumental analysis, scanningelectron microscopy, optical microscopy, particle size, x-ray diffraction, swellingpower and solubility, paste clarity, pasting properties, thermal properties, andabsolute density are used to evaluate the isolated starches. Yield increased from29.85% (control) to 32.09% (70% amplitude, 15 min). The surface of certainsonicated treated starch becomes damaged, also amorphous region is reduced,but no change in the crystalline pattern of starch is observed, characterized as Btype. Except for treated starches at 70% amplitude for 15 min, all others showedno change or slight increase of peak viscosity. Despite the increase in yield,ultrasound caused changes on physical and chemical characteristics, dependingon time and amplitude, hence it may be used as alternative technique forphysical starch modification, for example, for producing thickeners agent. |
