Technological Studies on Jerusalem Artichoke, Carrot and Turnip

This work aimed to study the effect of calcium spraying on total vegetation during growth period on the shelf life of vegetables turnip, carrot and Jerusalem artichoke as a fresh tubers, and after pickling process. The results revealed that treating vegetables by spraying in(18% Cao) and carbomax (30 % Cao) solutions  in spraying by rate 1 gram / 1 liter water after month from planting vegetables by rate once every week until harvesting season ,calcium chloride was added to a samples without spraying calcium for comparing fresh tubers . The obtained data showed that the spraying micronate lead to increasing. The shelf life of both turnip and carrot by rate 2 days, compared the Jerusalem artichoke by rate 3 days in fresh state comparing with control sample. Carbomax spraying lead to increasing of shelf life of turnip (3 days) while lead on increasing the shelf life of both carrot and Jerusalem artichoke by rate 5 days in fresh state comparing with control sample. In pickling process, the calcium added or sprayed lead to increasing the period shelf life obliviously, which added Cao lead to increasing. The shelf life of prickled turnip from 63 days in control sample to 95 days and increasing the shelf life of prickled carrot from 94 days in control to 122 days, too increasing the shelf life of pickled Jerusalem artichoke from 340 days in control sample to 351 days and that, is was nearly with sprayed calcium micronate
While Carbbomax sprayed lead to on increasing of the shelf life of pickled turnip from 63 days in control sample to 97 and lead to increasing the shelf life of prickled carrot from 94 days in control sample to 125 days, too increasing the shelf life of prickled Jerusalem artichoke from 340 days in control sample to 355 days .Finally in organoleptic evaluation ,the pickled  which sprayed or added calcium for it had got a high score than control samples in all characteristics  and over all acceptability.
