| dc.description.abstract | The present study was undertaken to Design and optimization of Modified Atmosphere Packaging (MAP) for black carrot (Dacus carota L.) to obtain the maximum shelf life on the basis of quality attributes and sensory evaluation during the storage study experiment. Respiration and transpiration rates of black carrot at different temperatures viz. 5, 10 and 15°C were determined. The respiration rate was described assuming the mixed model inhibition in the enzyme kinetics model. Arrhenius relationship was used to explain the temperature dependence of respiration rate, respiratory quotient and transpiration rate of fresh black carrot. A theoretical analysis for design of MAP for selection of appropriate packaging film was carried out by matching the data obtained in respiration study with the permeabilities of commercially available packaging films. Black carrot was packed in LDPE and stored under different conditions such as film thickness: 100, 150, 200 gauge; package fill weight = 100, 300, 500g; level of perforations: 0, 2, 4; storage temperature: 5, 10, 15°C. The qualitative analysis of black carrot throughout the storage study was done in terms physiological loss in weight, total colour difference, firmness, total soluble solids, antioxidants, flavonoids and anthocyanins. Sensory evaluation was done on the basis of visual appearance, odour rating and water accumulation. The study also revealed that the low temperature storage better retained the quality and quantity of fresh black carrot during its storage. MAP along with low temperature storage helped in enhancing shelf life of fresh black carrot upto 24 days. The optimized conditions obtained for shelf life extension of black carrot under MAP by using response surface methodology was temperature: 5°C, film thickness: 200 gauge, fill weight: 500 g, perforations: 0. | en_US |
