Here we studied the modification of fibres derived from the fruit juice industry to prepare new value-added ingredients. These by-products are usually composted or used as animal feed. In this regard, fibres from apple, peach, and citrus fruit were enzymatically treated to improve their functional properties,
with the aim to use them as food ingredients. Several enzymes were selected to modify various parts of the polymers present in the fibres. The effect of the treatments was assessed by comparing the water-holding capacity (WHC) and swelling water capacity (SWC) of the modified and raw fibres. FTIR spectrometry was also used to monitor changes in fibre structure. After the enzymatic modifications, some of these fibres not only showed an increase in WHC and SWC compared with the starting material but also greater viscosity.

Recycling Rhizopus oryzae resting cells as biocatalyst to prepare near eutectic palmitic-stearic acid mixtures from non-edible fat Gallart-Sirvent, Pau; Yara Varón, Edinson; Villorbina Noguera, Gemma; Balcells Fluvià, Mercè; Sala i Martí, Núria; Canela i Garayoa, Ramon (Elsevier, 2016)Here we studied non-edible fat waste as a starting material to prepare eutectic mixtures of biomaterials. Initially, the fat was hydrolyzed using water and R. oryzae resting cells. The hydrolysis was performed in organic ...
Gallart-Sirvent, Pau; Martín, Marc; Villorbina Noguera, Gemma; Balcells Fluvià, Mercè; Solé, Aran; Barreneche Güerisoli, Camila; Cabeza, Luisa F.; Canela i Garayoa, Ramon (Royal Society of Chemistry, 2017)A set of compounds from non-edible fat waste was prepared and their thermal behavior was studied. The fat was hydrolyzed and crystallized in a simple and robust process to yield palmitic acid-stearic acid (PA-SA) mixtures. ...
Canela Xandri, Anna; Villorbina Noguera, Gemma; Balcells Fluvià, Mercè; Fernández Francos, Xavier; Cabeza, Luisa F.; Canela i Garayoa, Ramon (MDPI, 2019)Nine monoamides were synthesized from carboxylic acids (C8-C18) and crude glycerol. The final monoamides were the result of a rearrangement of the acyl chain during the final hydrogenation process. The purity of the final ...
