Pearled amaranth grains obtained by abrasive milling were processed by planetary ball milling to produce amaranth flours. The influence of milling energy on rheological and thermal behavior of amaranth flour dispersions and stability during 24 h storage at 4 °C were investigated based on a factorial design. The rheological behavior of flour dispersions (4 % and 8 % w/v) was determined using a rotational viscometer, while gelatinization degree was determined by differential scanning calorimetry as a measure of structural changes.

A method involving hydration, tempering and heating steps is presented to process rough rice as alternative to traditional parboiling with pressure steam. The effects of temperature (66-84 °C), tempering time (60-420 min) and heating time (30-180 min) on gelatinization degree and milling yield were analyzed by response surface method (RSM). A maximum value of gelatinization degree (37.

Article Synopsis
- Willow seeds are typically orthodox but exhibit some recalcitrant traits, losing viability quickly at room temperature.
- The study aimed to enhance the desiccation tolerance of willow seeds (Salix nigra L.) using different imbibition solutions and dehydration methods (vacuum or freeze-drying).
- Results showed that trehalose-treated seeds had better germination after vacuum drying, while freeze-drying negatively impacted seed germination due to water crystallization, highlighting the importance of protective agents and dehydration techniques for seed preservation.
