“…The theoretical models can be divided into single-phase model and multiphase model. The single-phase model assumes that diffusion drives moisture migration, but only considers mass transfer and conduction as energy transfer mechanisms without accounting for other important drying properties (Rahman et al, 2015;Kumar et al, 2016). The multi-phase model considers the coupled three-phase mass and heat transfer of liquid water, gas, and solid in the drying of porous materials.…”

The shrinkage characteristic of porous materials is an important consideration in the drying process, as it can significantly impact the texture of the dried product and energy utilization. This phenomenon is influenced by numerous factors, including the structure of the cells, drying conditions, and the glass transition temperature. To gain a deeper understanding of the drying process, it is necessary to develop theoretical models that account for the simultaneous heat and mass transfer processes at the cellular level, as well as simulation tools to analyze the associated changes in drying morphology. In this paper, we highlight several key factors affecting shrinkage during the drying of porous materials, and also outline drying modeling, morphological simulation, and drying technology design considerations to provide guidance for improving the drying quality of porous materials as well as energy conversion efficiency.

“…High cost of production and diminishing economic returns from agricultural practices are affecting the socio-economic condition of the farmers. Loss of soil fertility, erosion of soil, soil toxicity, diminishing water resources, pollution of underground water, salinity of underground water, increased incidence of human and livestock diseases, and the risk of food toxicity enhances with indiscriminate and disproportionate use of Agro-chemicals (Rahman, 2015). Application of Chemical fertilizers induced higher crop productivity but at the same time they also led to the alteration of soil physicochemical and biological properties, decline of soil organic matter (SOM) content coupled with a decrease in the quality of agricultural soil (Pahalvi, 2021).…”

Today it is no longer a debatable issue that since the "green revolution" of the 1960s has been touted as solutions to the global hunger problem by focusing only on the potentiality of high crop yields have come at the cost of environmental degradation and lowered sustainable food and nutritional security over the long term.Especially in the crop intensified zones, rampant use of chemical fertilizer and pesticides made the soil and overall environmental quality to an alarming stage.Thus, shifting focus towards ecologically and economically sustainable crop cultivation is the only option left for future crop sustainability. In this background, pesticide free 'Clean Food production' with adoption of various good agricultural practices (GAP), mechanical and biological practices amalgamated with innovative organic approach (IRF technology) specially focused towards soil and plant health management have been adopted in some villages of Fathepur Gram Panchayat in the Haringhata Block, Nadia district of West Bengal from 2020. Analysis of soil samples in the study area clearly indicated soil quality depletion with very low organic carbon (< 0.60 %), very poor biological properties, poor microbial biomass carbon (<200 µg.CO2.C/gm dry soil) and poor FDAH (< 50 µg/gm dry soil). Comparative evaluation of crop productivity under Clean Food programme vis-a-vis conventional farmers' field indicated increase in crop yields even in the 1st year of program adoption. Analysis of pesticide residue indicated presence of pesticides residue in less than 4% of the vegetable samples, while in the rest the same were below detection limit (< 0.01 ppm). Post production soil development index indicated enhancement in soil quality which was majorly due to the activation of soil biological properties through the application of compost as well as reduction in the use of herbicides and chemical pesticides. The Clean Food program can be a practical option for sustainable agriculture towards crop sustainability, environmental preservation and empowerment of the small and marginal farmers.

“…It is common for dried food to have less than 25% water content and a water activity of less than 0.06 [ 9 , 10 ]. Food drying may enhance storage capacity, reduce production needs, and decrease the weight and transportation costs of food [ 11 ]. The drying process not only helps to preserve the product but also has the potential to improve the overall quality of the materials and to produce value-added compounds.…”

Drying fruits and vegetables is a procedure of food preservation with simultaneous heat, mass, and momentum transfer, which increases the shelf life of the food product. The aim of this review was to provide an overview of the researches on mathematical modeling for drying of fruits and vegetables with the special emphasis on the computational approach. Various heat-mass transport models, their applications, and modern drying technologies to the food industry have been reported in this study. Computational fluid dynamics, a new approach for solving heat and mass transfer problems, increases the accuracy of the predicted values. To investigate the parameters of drying needs a significant amount of time as well as costly laboratory and experimental efforts. Therefore, computational modeling could be an effective alternative to experimental approaches. This review will be beneficial for future studies in drying processes, especially for modeling, analysis, design, and optimization of food science and food engineering.
