Potato processing storage temperature

Potatoes are cultivated in areas where they can be stored throughout the winter in temperature-conditioned sheds. For economical potato processing, the length of the campaign should be an optimum between the capacity of the factory, and thus the costs of investment and processing, and starch losses during potato storage, particularly... 

Ascorbic acid is photosensitive and unstable in aqueous solution at room temperature. During storage of foods, vitamin C is inactivated by oxygen. This process is accelerated by heat and the presence of catalysts. Ascorbic acid concentration in human organs is highest in adrenal and pituitary glands, eye lens, liver, spleen, and brain. Potatoes, citrus fruits, blade currants, sea buckthorns, acerola, rose hips, and red paprika peppers are among the most valuable vitamin C sources [1,2]. 

Preconditioning is used commercially by chip-potato processors to compensate the unpredictable nature of reconditioning of process varieties and to achieve market flexibility (Brook et al., 1995). During this phase, the storage environment is maintained at conditions similar to the wound healing phase (12-16°C) with the pulp temperature actively controlled in order to eliminate pools of reducing sugars in process potatoes. The duration of this phase is dependent...
