AbstractThe aim of the study was to evaluate the influence of various chemical forms of iodine (I−and IO3−) and selenium (SeO32−and SeO42−) on the nutritional and health-promoting quality of carrot (Daucus carotaL.) storage roots. The experiment (conducted in 2012-2014) comprised the soil fertilization of carrot ‘Kazan’ F1in the following combinations: 1. Control, 2. KI, 3. KIO3, 4. Na2SeO4, 5. Na2SeO3, 6. KI + Na2SeO4, 7. KIO3+ Na2SeO4, 8. KI + Na2SeO3, 9. KIO3+ Na2SeO3. Iodine and selenium were applied twice: before sowing and as top dressing in a total dose of 5 kg I ha−1and 1 kg Se ha−1. No significant influence of iodine and selenium fertilization was noted with respect to average root weight and leaf yield. Each year, the application of KI + Na2SeO4negatively affected the content of glucose and total sugars in carrot. An increased sucrose level was noted in the roots of plants treated with KIO3+ Na2SeO4, with a total sugar concentration comparable to the control. Irrespective of the year, carrots fertilized with KI were characterized by the highest accumulation of nitrates (III) – NO2−in roots. The simultaneous introduction of iodine and selenium compounds (KI + Na2SeO4, KIO3+ Na2SeO4, KI + Na2SeO3and KIO3+ Na2SeO3) into the soil reduced the content of nitrates (III) in carrot as compared to combinations with the individual application of these compounds. The influence of the tested factors on other analysed parameters (the content of dry weight, nitrates (V), chlorides, oxalates, citrates, free amino acids, carotenoids, phenolic compounds, phenylpropanoids, flavonols and anthocyanins as well as free radical scavenging activity (DPPH) was rather year-dependent.

Daucus Carota L

The chemical composition of the calcium-rich crystal inclusions present in the seed protein bodies of carrot (Daucus carota L. cv. Imperator 408), wild carrot (Daucus carota L.), caraway (Carum carvi L.), anise (Pimpinella anisum L.), dill (Anethum graveolens L.), celery (Apium graveolens L. cv. Tall Utah), fennel (Foeniculum vulgare Mill.), parsnip (Pastinaca sativa L. cv. Hollow Crown), parsley (Petroselinum sativum L. cv. Moss Curled), and chervil (Anthriscus cerefolium L. cv. Curled) was determined. Using a variety of methods including X-ray diffraction, infrared spectroscopy, microincineration, energy dispersive X-ray analysis, solubility studies, and staining, the chemical composition of the calcium-rich crystal inclusions was identified as calcium oxalate.

Influence of preliminary osmotic dehydration on drying kinetics and final quality of carrot (Daucus carotaL.)This paper concerns convective drying of carrot preliminary dehydrated in aqueous solutions of three types of osmotic agents (sucrose, fructose, glucose). Three solution concentrations (20, 40 and 60%) were examined to work out efficient conditions of osmotic dewatering. The parameters such as water loss (WL), solid gain (SG) and osmotic drying rate (ODR) indicating the real efficiency of osmotic dehydrations (OD) were determined. The samples dehydrated with osmotic solutions underwent further convective drying to analyze influence of dehydration process on drying kinetics and final products quality. The quality of products was assessed on the basis of visual appearance of the samples and colorimetric measurements. It was found that osmotic pretreatment improves significantly the final product quality as the samples were less deformed and their colour was better preserved compared to samples, which had not been preliminarily dehydrated. Preliminary dehydration, however, did not influence significantly the overall drying time of the samples.
