High-intensity ultrasound irradiation proved to be an effective method for modifying tara gum by generating low molecular weight products and better water solubility. The objectives of this research were to optimize the parameters for the high-intensity ultrasonic treatment with response surface methodology and improve the tara gum solubility. The results demonstrated that after the ultrasound treatment, the solubility of the tara gum had increased (17.7%) as a result of the reduced intrinsic viscosity (70%). The molecular weight of the untreated tara gum was 1.89 x 106 Da, and after ultrasound treatment, it was reduced to 0.47 x 106 Da. Rheological analyses confirmed the reduction in molecular weight for the modified and optimized tara gum and the resulting increase in solubility. This knowledge provides a better understanding of ultrasound treatment technology and increases the scope for use of tara gum in the food industry. |

The germination of banana seeds is one of several drawbacks in genetic breeding. Besides extreme variability under artificial conditions, germination can be affected by many features, including seed physiological maturity, intensity of disinfection treatment, culture media composition and size, type and morphological aspects of embryos. Seeds from the banana genetic breeding program at Embrapa Cassava & Fruits were studied in order to assess the influence of the parents on the germination rate and the occurrence of abnormalities in embryo structure. |
