Carrot storage conditions

The comparison of the light effect on carotenoids in foods is very difficult to carry out because different foods with different isomer compositions are employed at the beginnings of experiments. The presence of large molecules offers some photoprotection to carotenoids in food systems, either by complexation with proteins as found in carrots or acting as a filter to reduce the light incidence. Different storage conditions are often found because different light intensities are used or sometimes they are not even reported and experiments are carried out under air, N2, or in a vacuum. 

Details of preparation and storage conditions for crops that last well through the winter are given here (seepanel, left). Some other crops can also be stored for shorter periods for example, carrots, parsnips, beets, rutabagas, and celeriac keep well if packed in moist sand or fine leaf mold in shallow trays or boxes. 

Manley et al. (2011) used near infrared hyperspectral imaging combined with chemometrics techniques for tracking diffusion of conditioning water in single wheat kernels of different hardnesses. NIR analysers is a commonly, non-destructive, non-contact and fast solution for quality control, and a used tool to detect the moisture-content of carrot samples during storage but Firtha (2009) used hyperspectral system that is able to detect the spatied... 

Sra et al. reported that the dried carrot shoes pretreated with 6% KMS and packed in AFL pouches (polyethylene, aluminum foil and polyester) retained the physicochemical quality at an acceptable level up to 6 months imder ambient conditions, the maintenance of quality was better in AFL pouches (32.5 pm) than that in HDPE pouches (56.0 pm) (2011). A study on storage of aloevera gel powder in three different packaging materials viz., laminated aluminum foil (AF), biaxially oriented polypropylene (BOPP) and PP suggest that packaging in AF is better than that in BOPP and PP in terms of color change (Ramachandra and Rao, 2011).
