“…From the literature survey, it is evident that though there are many dryer designs which involve the flow of air between glass cover and absorber plate in the collector [20] and also in some other designs, the flow is maintained between absorber plate and bottom insulation [21]. However, there is no comparison of the performance done between these two cases in a single setup.…”

Background: An indirect, active-type, environmentally friendly, low-cost solar dryer was designed to dry various agricultural products. The dryer was built by locally available, biologically degradable, low-cost materials. The dryer consists of solar flat plate air heater with three layers of insulation, drying chamber and a fan with a regulator to induce required air flow in the system. Banana is the chosen crop for the experimentation since it is high in production and also has substantial loss in India. Also, dried bananas are having good nutritive value which makes it as essential diet.

A performance analysis of indirect natural convection solar dryer (INCSD) was carried out by drying anti‐diabetic medicinal products like coccinia grandis, allium cepa, and emblica officinalis by cutting into different orientations. Drying results shows that thickness, orientation of cut, and surface area plays a vital role in the drying characteristics of the products in INCSD. The average collector and dryer efficiency of INCSD was 15% and 7%, respectively. Drying time was reduced up to 11 hr in INCSD than open sun drying. Alpha amylase inhibition assay values for products dried under open sun (15.67%, 5.89%, and 8.56%) showed better results, whereas minerals like potassium content in allium cepa (597 mg/100 g), sodium content in coccinia grandis (130.1 mg/100 g), magnesium content in allium cepa, and emblica officinalis (80 mg/100 g) were higher when dried in INCSD. Vitamin C and sugar content in products were almost same for both INCSD and open sun drying. Practical applicationsIndirect natural convection solar dryers are mainly benefited by small‐scale farmers as it takes less drying time and possess better quality when compared to open sun drying. Drying anti‐diabetic medicinal products in INCSD can be considered as a boon for pharmaceutical industries as the dryer can give good‐quality dried products that can be used for preparing anti‐diabetic medicines. It can also reduce the production cost of anti‐diabetic medicines.

“…); thus, it is impossible to achieve uniform drying of grains. In Africa, sun drying is efficient and effective since there is almost 13-h of sun during the dry season [127]. Applying excessive temperatures (using artificial means) can lead to grains cracking, loss of viability, as well as economic losses [122,128].…”

Mycotoxins and Food Safety

Cereals and legumes are the major staples across the globe, thus providing nutrition to humans, and their by-products utilized as animal feeds. However, mycotoxins synthesized by fungi contaminate these grains on the field during cultivation and are transferred to the storage centers. These fungi infect and deteriorate stored grains, thereby tampering with food security. Moreover, the deterioration decreases nutrient content and alters the physicochemical properties of grains. The current conventional methods used to reduce grain contamination are becoming ineffecitive, coupled with the detrimental health effects it has on the consumer and to the environment. Herein, we present an overview of the use of nanoparticles (NPs) as an alternative and novel method of reducing mycotoxin biosynthesis due to their potent biocidal properties. Silver nanoparticles (AgNPs) are considered and have shown promising and effective fungicidal properties against important storage fungi, and pests hence could be utilized in the agriculture and food sector for a vast myriad of applications. These may help to either minimize/eradicate the exposure to the mycotoxins and its adverse health effects, hence contributing to the holistic growth and development of people.
