Article
The study focuses on development of modified atmosphere packaging for fresh-cut minimally processed cauliflower to increase its shelf-life and enhancing the on-farm value addition by utilizing perforated packaging films along with pretreatments with ozonated water and antimicrobials. The samples were treated with ozonated water, oregano essential o...
Article
This work aims to develop a finite element (FE) model for predicting temperature and moisture ratio of potato cylinders having diameters of 8, 10, 13 mm and 50 mm length during solar drying using COMSOL Multiphysics software. The developed model computed conduction, convection, and radiation with appropriate governing and boundary conditions by cou...
Article
The present study evaluates the effects of hot air drying (HAD) and direct solar drying (DSD) on drying kinetics and properties of turmeric. Obtained results unveiled higher effective diffusivity (1.98 × 10 − 8-13.1 × 10 − 8 m 2 / s) and lower drying time (3.5 h) for DSD turmeric than HAD (2.19 × 10 − 8-2.67 × 10 − 8 m 2 /s and 4.5 h). Page and dif...

In the present work, computer vision technology was adopted to study the effect of direct solar drying on quality attributes of turmeric in terms of color, morphology, texture, browning factor and shrinkage. Drying experiments were carried out with turmeric slices placed in an in-house built natural convection direct solar dryer. A standardized ima...
Article
Modified atmosphere (MA) packaging with selective permeability and incorporating active ingredients (clove and garlic) was developed to extend the shelf life of paddy straw mushroom. On the basis of preliminary investigations, sub-optimal package air composition of 5% O2 and 5% CO2 was appropriate for designing the optimal MA packages of low densit...

Shelf life and quality of paddy straw (Volvariella volvacea) mushroom treated with citric acid (CA), potassium metabisulphite (KMS), calcium chloride (CaCl2) and calcium hypochloride (CaCl2O2) and packed in low density poly-ethylene (LDPE) with 0, 15, 35 and 60 perforations (0%, 0.001%, 0.002% and 0.004 % total opening area respectively) with the h...
Article
Most food industries perceive the significance of microscopy-based approaches to optimize existing drying processes to improve and control characteristics in dried food products. In this work, pretreated potato cylinders of 50 mm length and varying diameters of 8, 10 and 13 mm were dried in a mixed-mode solar dryer. Effect of pretreatment on surfac...
Article
Heat transfer analysis during mixed-mode solar drying of foodstuff is crucial in food industries now-a-days as better understanding of the phenomena will assist in suitable design and optimization of the drying process parameters. In the present work, natural convection mixed-mode solar drying experiments were carried out with potato cylinders of v...

In the present study modified atmospheric (MA) packages, having package size of 19 × 19 cm² for a fill weight of 500 ± 100 g were developed for the experimental purpose. The storage study of MA packages was performed at 10 ± 1, 18 ± 1 and 27 ± 1 °C temperatures, considering low-density polyethylene (LDPE) packaging film with 0.1, 0.05, 0.025 and 0....
Article
Background: Desirable quality estimation is an important consumer driver for wider acceptability of mixed-mode solar drying of potatoes in food industries. The aim of this study is to characterize rehydration, colour, texture, nanoindentaion and microstructure of dried potato samples and to establish the influence of pre-drying treatment on above...
Article
In the present work, the thin layer drying kinetics of potato during natural convection solar drying was investigated experimentally. Cylindrical potato samples with length 50 mm and varying diameter of 8, 10 and 13 mm were dried in an in-house designed and fabricated laboratory scale mixed-mode solar dryer. Thirteen different thin-layer mathematic...
