    Effect of edible coatings enriched with karonda polyphenolic extract for improving the post-harvest quality of ber
    (Punjab Agricultural University, Ludhiana, 2022) Karandeep Kaur; Gupta, Navjot
    The present investigation entitled “Effect of edible coatings enriched with karonda polyphenolic extract for improving the post-harvest quality of ber” was conducted at the Food Quality Control Lab of Regional Research Station, Bathinda during the year 2021. Healthy and uniform sized ber fruits of cv. Umran were coated with pectin (1%), chitosan (1%) and beeswax (2%) alone, as well as with these coatings infused with karonda polyphenolic extract (K-PPE) in concentrations of 0.5, 1.0 and 1.5% and packed in corrugated fibre board (CFB) boxes (5% perforation) with paper lining before storage at 7.5 °C and 90-95% RH for 28 days. Fruits were analysed for physical and biochemical parameters at 7, 14, 21 and 28 days interval. Results revealed that the physiological loss in weight and spoilage increased progressively with the progression in storage period. Fruit firmness, titratable acidity, vitamin C content, total phenols, flavonoids and antioxidant activity of ber fruit showed a declining trend with the progression of storage period. Whereas, total soluble solids (TSS), sugars, pectin methyl esterase (PME) and cellulase enzyme activity exhibited an initial increase in all the fruits during storage followed by a decreasing trend towards the end of storage period. However, the rate of increase in TSS, sugars, PME and cellulase enzyme activity was slower in coated fruits as compared to uncoated fruits. The ber fruits coated with beeswax (2%) + K+PPE (1.5%) showed a prolonged shelf life up to 28 days under low temperature storage conditions by exhibiting moderately desirable sensory quality, minimum physiological loss in weight as well as spoilage percentage and maintaining higher content of TSS, titratable acidity, Vitamin C, total sugars, phenols, flavonoids, antioxidant activity and optimally maintaining PME and cellulase enzymatic activity of fruits during storage.

    KNITWEAR PRODUCT DEVELOPMENT USING KASUTI EMBROIDERY MOTIFS
    (PAU Ludhiana, 2013) Karandeep Kaur; Devinder Kaur
    The investigation entitled ‘Knitwear product development using kasuti embroidery motifs’ was carried out in Ludhiana city. Traditional motifs of kasuti embroidery were selected and plates were developed through Corel Draw 13 and were shown to 10 panel of judges. After the selection of motifs, three colour combinations of each motif were developed and again shown to 20 judges to finalize the 10 colour combinations of the 10 selected motifs for the development of design. After that two different design placements were prepared of the 10 most preferred motifs and their colour combinations. An interview schedule was prepared for the purpose of collecting data from 80 female respondents between the age group of 20 to 30 years selected randomly from three colleges of Ludhiana city. The results of the study revealed that majority of the respondents were graduates, belonging to nuclear families. Seventy per cent of the respondents were aware of knitwear designs and 51.25 per cent aware of kasuti embroidery and 70 per cent respondents preferred to buy knitwear kurtis. Readymade kurtis were the most preferred kurtis with medium length and V-shape necklines. Multi coloured combination was the most preferred colour combination followed by two colour and three colour combinations. Skin, pista green, red and cream were the most preferred colours. After this second interview schedule was prepared to study the preferences for the developed knitwear kurtis. For this purpose four localities of Ludhiana city were selected. All the kurtis were highly appreciated on the basis of colour combinations and overall impact where as kurti D10 was the most preferred kurti. Majority of the respondents rated all the kurtis as very good. The quoted price of the kurtis was found to be adequate and 30.72 to 50 percent profit can be earned by making knitwear kurtis.
