“…Anastopoulos et al [ 18 ] have also demonstrated that the incorporation of TPW and BPW in soil has a significant effect on the bacterial community structure and the bacterial guild abundance associated with nitrous oxide emissions. The usage of TPW, PPW and BPW or their biochar have also helped plants to resist diseases [ 19 , 151 , 153 ]. Furthermore, the spread of unstable TPW, PPW and BPW to soil could result the depletion of soil oxygen and the emission of harmful odours in treated crop fields.…”

Processing Factors Affecting the Phytochemical and Nutritional Properties of Pomegranate (Punica granatum L.) Peel Waste: A Review

et al. 2020

Pomegranate peel has substantial amounts of phenolic compounds, such as hydrolysable tannins (punicalin, punicalagin, ellagic acid, and gallic acid), flavonoids (anthocyanins and catechins), and nutrients, which are responsible for its biological activity. However, during processing, the level of peel compounds can be significantly altered depending on the peel processing technique used, for example, ranging from 38.6 to 50.3 mg/g for punicalagins. This review focuses on the influence of postharvest processing factors on the pharmacological, phytochemical, and nutritional properties of pomegranate (Punica granatum L.) peel. Various peel drying strategies (sun drying, microwave drying, vacuum drying, and oven drying) and different extraction protocols (solvent, super-critical fluid, ultrasound-assisted, microwave-assisted, and pressurized liquid extractions) that are used to recover phytochemical compounds of the pomegranate peel are described. A total phenolic content of 40.8 mg gallic acid equivalent (GAE)/g DM was recorded when sun drying was used, but the recovery of the total phenolic content was higher at 264.3 mg TAE/g when pressurised liquid extraction was performed. However, pressurised liquid extraction is costly due to the high initial investment costs and the limited possibility of carrying out selective extractions of organic compounds from complex peel samples. The effects of these methods on the phytochemical profiles of pomegranate peel extracts are also influenced by the cultivar and conditions used, making it difficult to determine best practice. For example, oven drying at 60 °C resulted in higher levels of punicalin of 888.04 mg CE/kg DM compared to those obtained 40 °C of 768.11 mg CE/kg DM for the Wonderful cultivar. Processes that are easy to set up, cost-effective, and do not compromise the quality and safety aspects of the peel are, thus, more desirable. From the literature survey, we identified a lack of studies testing pretreatment protocols that may result in a lower loss of the valuable biological compounds of pomegranate peels to allow for full exploitation of their health-promoting properties in potentially new value-added products.

Comprehensive review on production and utilization of biochar

2019

View full text Add to dashboard Cite

The on-farm burning of crop residues and biomass results in numerous environmental issues and affects human beings. Crop residues have considerable energy potential if utilized appropriately. Crop residues can be converted into biochar through thermo-chemical routes; conversion helps in the managing and handling of biomass. Biochar reactors usually operate at temperatures between 400 and 600 °C with fixed carbon contents ranging from 60 to 85%. The application of this biochar to soil improves the physiochemical characteristics of soil because biochar is rich in organic carbon content, which makes the soil more fertile and acts as a carbon sequestration agent over the long term. Biochar itself is considered a source nutrient and can alter the soil nutrient pools and availability. Biochar applied up to 10 cm depth of soil may decrease the denitrification potential and lower N 2 O emission, greatly controlling leaching of mobile nutrients such as potassium, thus improving water use efficiency, nutrient availability and plant growth. Furthermore, it reduces the leaching of nitrogen into the groundwater and increases the water retention and cation-exchange capacity while moderating the soil's acidity, resulting in improved soil fertility. This article discusses different biochar production processes and various feedstocks and characteristics of biochar. The factors affecting biochar production and advantages of the utilization of biochar in soil are also reviewed.
