Valorized pineapple waste by conventional and energy-saving ohmic extraction: potentially toxic elements and mycotoxin contamination
Pineapple peel is a food waste with environmental concerns. It can be valorized by extracting its bioactive compound through conventional and emerging technologies such as ohmic heating. However, mycotoxins and heavy metals contaminations could be concerns of such a valorization process. This study assessed the effects of conventional and ohmic heating on selected aflatoxins and metal ions in pineapple peel extract using high- performance liquid chromatography (HPLC) and inductively coupled plasma mass spectrometry (ICP-MS). Also, energy consumption and environmental impacts of the ohmic process were analyzed. According to the results, the ohmic-based valorization system reduced energy consumption and greenhouse gas emissions by more than 83%, contributing to net-zero and sustainable development goals (SDGs). Aflatoxins B1, B2, G1, and G2 were below the detection limit (B1, G1: 0.2µg/kg; B2, G2: 0.1µg/kg). However, ohmic extracts contained higher concentrations of Cr, Pb, Ni, and Fe because of electrochemical reactions and electrode corrosion. Despite the capability of ohmic valorization systems, inspecting food waste and valorized products for hazardous chemicals and investing in durable electrodes (e.g., titanium) are among the considerations for ohmic systems’ industrial implementation.
期刊介绍:
''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered.
''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
