“…Furthermore, it improves soil biometric parameters, directly adds nutrients, solubilises native phosphate content in the soil (Das et al, 2002) and augments nutrient use efficiency (Lakpale et al, 1999). RHA and PPC contain substantial amounts of nutrients and utilizing them in FYM/ compost preparation encrich the quality and on application release the nutrients for easier uptake by the crop plants (da Silva et al, 2020;Joshi et al, 2020;Hisham and Ramli, 2021;Nepal et al, 2021). These combined effects lead to increased concentrations of N, P, and K in babycorn, kabuli gram and vegetable cowpea crops.…”

“…This increase in availability of nutrients is likely a result of the mineralization process of organic manure, as well as the natural release of nutrients from the native soil due to favourable relationship between the soil, plants and atmosphere (Rosen and Allan, 2007;Mohanty et al, 2013;Dhaliwal et al, 2019). Further, RHA and PPC for preparing formulation add significant amounts of nutrients and increase the nutrient avaibility for plant uptake and growth (da Silva et al, 2020;Joshi et al, 2020;Hisham and Ramli, 2021;Nepal et al, 2021).…”

The preparation of enriched formulation by integrating of agricultural wastes such as paddy husk ash (PHA) and potato peel with organic fertilizer such as farmyard manure (FYM), compost can enrich the soil with essential plant nutrients, leading to higher yields in subsequent crops and potentially reducing the dependence on farmyard manure/compost alone. However, there is lack of adequate research findings regarding the impact of different formulations generated from agricultural waste on productivity, nutrient utilization efficiency and profitability of baby corn-kabuli gram-vegetable cowpea cropping system. Therefore, a two-year field experiment (2020–2022) was conducted ICAR-IARI, New Delhi with baby corn-kabuli gram-vegetable cowpea cropping system. Seven nutrient sources were tested in Randomized Block Design and replicate thrice.The results showed that treatment T4 (100% recommended dose of nitrogen (RDN) through PHA based formulation) had significant effect on crop yield grown in rotation, followed by treatment T6 (100% RDN through potato peel compost (PPC) based formulation) and T2 (100% RDN through FYM). The increase in yield was 75.0, 44.3 and 33.1% during first year and 72.6, 45.9 and 31.0% during second year, respectively, over control. Treatment T4 also significantly enhanced system uptake of N, P and K as well as system gross returns and net returns, resulting in 65.6, 84.9, 69.5, 50.7 and 55.2% higher returns during first year and 68.6, 80.5, 73.9, 50.0 and 54.2% higher returns during second year, respectively, over control. Furthermore, treatment T4 significantly improved agronomic nitrogen use efficiency and apparent recovery by 151.6 and 2.0% in baby corn, 74.2 and 1.5% in kabuli gram, 55.7 and 13.9% in veg cowpea over T7, respectively, averaged across two years of study. Based on these results, it is recommended to adopt (T4) 100% RDN through PHA based formulation, and (T6) 100% RDN through PPC based formulation in the area with a shortage of FYM but with the availability of rice husk ash or pototo peels for sustainable utilization of the agricultural wastes and improving the agricultural sustainability.

“…A number of studies have shown that food processing steps such as washing, boiling, and juicing can reduce the level of pesticide residues in food to a large extent [47][48][49]. However, some processing steps that involve dehydration lead to a concentration of pesticides [47,50,51]. Factors such as temperature and microbial activities can also cause pesticide residues to undergo transformation, leading to the contamination of food processing by-products with other chemicals [47,52,53].…”

“…As in the case of apple pomace, other by-products can present risks in the form of toxins that are unique to them. When valorizing potato peels, for instance, glycoalkaloids found in the Solanum genera are a potential hazard [8,50]. While glycoalkaloids are present in various parts of the potato, they are more concentrated in peels.…”

Valorized Food Processing By-Products in the EU: Finding the Balance between Safety, Nutrition, and Sustainability

2021

Food businesses in the European Union are preparing for a carbon-neutral future by gradually transitioning to a circular way of operating. Building upon results from the EU REFRESH project, we consider the most valuable food processing by-streams in Europe and discuss potential food safety risks that must be considered while valorizing them for human consumption. These risks are weighed against the nutritional benefits offered by these products and their potential applications in food supply chains. Broadly, we examine whether it is possible for spent grains, cheese whey, fruit and vegetable scraps, meat processing waste, and oilseed cakes and meals to be safe, sustainable, and nutritionally valuable at the same time. The discussion highlights that valorizing by-products obtained from food processing operations is feasible on a large scale only if consumers deem it to be a safe and acceptable practice. Extracting valuable compounds from by-products and using them in the preparation of functional foods could be a way to gain consumer acceptance. Furthermore, we find that current EU food safety legislation does not sufficiently accommodate food processing by-products. A way to bridge this regulatory gap could be through the adoption of private food safety standards that have shown proclivity for sustainability-related issues in food supply chains. Finally, by proposing a decision tree, we show that it is indeed feasible for some food processing by-products to be valorized while ensuring sustainability, food safety, and nutritional relevance.

“…1 Potato peel can be utilised as a food additive for dietary fibre, natural antioxidants and antimicrobials benefits. [2][3][4] As an antioxidant, potato peel extract is non-mutagenic and non-carcinogenic compared to synthetic preservatives. Drying of peel is a mandatory step for reducing moisture content to a sufficiently low level that inhibits microbial spoilage and curbs the biochemical changes.…”

Phenolic and antioxidant capacity retention of potato peel waste as a function of cultivar, pretreatment and drying procedure

et al. 2023

Drying procedures employed for potato peels (both raw and boiled) may adversely affect the useful bioactivecomponents present in them. This study envisaged the identification of a feasible drying procedure for handlingbulk potato peel waste for maximising the retention of phytochemicals in the peel powder. The total phenols (TP), flavonoids (TF) and antioxidant capacity (TAC) were assessed in peels of three commercial and one newly developed anthocyanin rich Indian potato cultivars in response to boiling pretreatment and varying drying procedures. Microwave drying (600W) was best in terms of drying rate for both raw and boiled peels. It yielded the greatest amount of TP and TF in the dried raw peel, irrespective of cultivar. Dried raw peels of an thocyanin rich Kufri Neelkanth cultivar exhibited maximum TAC. Retention of TF, metal scavenging activity and reducing power followed almost a similar pattern as TP irrespective of cultivar, pretreatment and drying procedure. Our study shows that potato peel from Kufri Neelkanth (raw) and Kufri Frysona (both raw and boiled) are best source of phenolics and flavonoids and can serve as a suitable matrix for extraction of bioactive compounds which holds promise for use in the food industry.
