Effects of Aspergillus niger in onion bulbs (Allium cepa L.) stored in the post–harvest phase
Onion bulbs were stored in the field, in piles until its commercialisation but the bulbs may be affected by fungal diseases. The objective was to assess the effects of the temperature (T), relative humidity (RH) within the piles, the water percentage (WP) and soluble solids (SS) of the bulbs over Aspergillus niger incidence. Bulbs of Cobriza INTA, Antártica INTA, Valcatorce INTA, Valuno ...

Biosorption of heavy metals by utilising onion and garlic wastes
Onion (Allium cepa L.) and garlic (Allium sativum L.) wastes from market and food canning processes were used for adsorption of Pb2+, Sn2+, Fe2+, Hg2+, As3+ and Cd2+ from multi–component systems at different adsorbent/metal ion ratios. The influence of pH, contact time, temperature and the concentration of adsorbent and adsorbate were studied to optimise the conditions to be utilised on a ...

Oxidative potential of UV‐A irradiated or non‐irradiated suspensions of TiO2 or SiO2 nanoparticles on Allium cepa roots
The effect of UV‐A irradiated or non‐irradiated suspensions of agglomerates of TiO2 or SiO2 nanoparticles on roots of the onion (Allium cepa) has been studied. The reactive potential of TiO2 nanoparticles which have photocatalytic potential and the non‐photocatalytic SiO2 nanoparticles with the same size of agglomerates was compared. We measured the activity of antioxidant enzyme glutathione ...
