Edible coatings are thin layers of edible materials formed directly on fruits, usually by immersing the fruits in a coating material solution, and they are one of the most intriguing food developments in recent years. Colorants, flavours, nutrients, and anti-browning and antimicrobial agents can all be carried by edible coatings, extending shelf life and reducing pathogen growth on food surfaces. To manage moisture transfer, gas exchange, or oxidative processes, edible coatings can be applied using various procedures such as dipping, spraying, or coating. Because these systems have a larger surface area, nanoparticles may help to improve the barrier characteristics and functionality of fruit preservation coatings. Antimicrobial nanoparticles (NPs) are employed as matrixes in edible coatings and films (ECF), which are then applied to fruits to extend shelf life and improve storage quality. Nano Chitosan is one of the most prevalent polysaccharides, protein, and lipid-based edible coatings. These are characterised by poor gas and water barrier qualities, and they are frequently used as moisture loss sacrifice agents. Therefore, the purpose of this book chapter is to study the effect of nano edible coatings such as chitosan/tripolyphosphate (TPP), chitosan-methyl cellulose/silica (SiO2), gelatin-fiber/titanium dioxide (TiO2), gelatin-chitosan/ (Ag/ZnO), Gelatin/kafirin to quality attributes and prolonging the shelf life of fruits.
The research trial was conducted at Lovely Professional University, Punjab, India. The hardwood stem cuttings of Mulberry basal portions were treated with 0, 150, 250, 500, and 750 ppm solutions of IBA for 24 hrs by slow dip method. The mulberry cuttings have rooted on raised beds under the open field conditions. In all the treatments, Number of sprouted cuttings, average length of sprouts (cm) and diameter of sprouts (mm) were higher in T2 treatment (IBA 150 mg l-1) and a live cutting (%), no. of roots/cutting, length of roots/cutting (cm) was higher in T5 treatment (IBA 750 mgl-1).
Strawberry is an important crop of temperate horticulture in India. There are several genotypes have beendeveloped for getting qualitative and quantitative attributes in production of strawberry. Less area intemperate region enhances the introduction of new strains. Current study was undertaken at the Horticulturalfarm, and laboratory, School of Agriculture, Lovely Professional University, Phagwara, Punjab, in 2020-21.The biochemical and quantitative attributes of strawberry genotypes were analysed in 10 genotypes viz.,Sweet Charlie, Florida, Tioga, Camerosa, Winter Dawn, Swiss, Red coat, San Andreas, Elista and Robinsonunder sub-tropical climatic conditions of Punjab. Experiment was laid down in a Randomized Block Design(RBD) with three replications. Results revealed that among all the genotypes, cv. Winter Dawn had thehigher yield of heaviest fruit, cv. Tioga had the highest total soluble solid (TSS), ascorbic acid and totalsugar whereas, cv. Sweet Charlie contained minimum acidity and cv. Florida hold maximum juice content.The finding can be helpful for grower to achieve consumers demand and researchers in crop improvement.
Background: Papaya (Carica papaya) has a maximum loss of postharvest shelf life. Due to the higher respiration activity, these are prone to ripening within a short time frame; as a result, pathogens develop quickly and lead to enormous problems for papaya producers. Hence to minimize this postharvest loss and to preserve nutritional qualities, the present study was conducted to utilize papaya pulp to prepare a delicious papaya chutney with tomato (Lycopersicon esculentum) because of its unique flavour. Methods: For chutney preparation, different combinations of papaya and tomato were used and their quality was analyzed based on biochemical (Total Soluble Solids, Titratable acidity, acid/Brix ratio, vitamin-C, total sugars, reducing sugars) and sensory attributes (colour, appearance, flavour, texture and consistency). Result: The treatment T7 (50% papaya: 50% tomato) was found to be the best combination in terms of biochemical and sensory quality parameters. Chutney was yet in acceptable conditions even after 90 days of preparation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
