The drying process for strawberries extends their shelf life but also changes their color and alters their nutritional contents. The anthocyanins are responsible for the color, which are susceptible to degradation during thermal processing, reducing the customer appeal of these food products. The benefit of solar drying of strawberry pulp using UV-Blue blocking optical filters compared with d irect solar drying is presented in this work. Total anthocyanins, antioxidant activity, and the color of the strawberry pulp were monitored as the drying progressed. The UV-Blue blocking optical filter consisted of a copper sulfide/copper selenide thin film of 160 nm in thickness applied on the outer surface of cellular polycarbonate sheets of 8 mm cell-size, 0.1 mm wall thickness (1 kg/m<sup>2</sup>) cut from sheets measuring 122 cm x 122 cm in area, and protected by a food-safe adhesive polyethylene foil. Total anthocyanins and antioxidant activity were measured using the differential pH and the DPPH (2,2-diphenyl-1-picrilhydrazil) methods. The filter preserves a higher total anthocyanin content and antioxidant activity in the dried product than in the pulp dried under sunlight conditions. A reduced total color change was observed in the product dried under the UV-Blue blocking solar filter. This study highlights a general need to evaluate the bioactive merits of solar dried farm produce to assess the advantage they hold for their commercialization.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"9 ","pages":"Article 100112"},"PeriodicalIF":0.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142528671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the causes of food loss and waste is crucial for the design of effective solutions and their prioritisation. The purpose of this study was to investigate the risk factors and underlying causes of FLW in leafy vegetables, spanning from agricultural production to retail. To achieve this, the research methodology encompassed a case study conducted among small-scale producers and retailers. A comprehensive approach was adopted by integrating a systematic literature review of global food loss and waste causes and those specific to the Latin American context. This approach was complemented by exploratory research, involving interviews with various stakeholders, coupled with root-cause analysis. A methodology was developed for the creation of a causal map, incorporating the 'Five Whys' technique, the current reality tree, and an interrelationship diagram. The study's findings underscore the critical role of retailer-supplier dynamics in the management and flow of products, identifying a significant research gap in the development of comprehensive strategies for waste reduction. By exploring these dynamics, particularly in the context of take-back agreements and the lack of public policies incentivizing food loss and waste reduction, the research reveals the multifaceted nature of food loss and waste and the necessity for collaborative efforts across the supply chain to mitigate its impacts.

Energy use for incubation and drying during the manufacturing stage is the most important contributor in most impact categories, including global warming potential. This is further underlined by the large sensitivity of the results to uncertainties related to energy-use. Overall, the manufacturing stage is the dominant life-cycle stage in terms of potential environmental impacts. Generally, our results agree with literature values of LCA studies on similar materials, when normalized for mass and volume.

The scientific community agree that transition to renewable energies will play a key role as a mitigation strategy for this problem. In this work, an abundant biomass resource of central-eastern zone of Argentina is evaluated: rangelands of the Submeridional Lowlands dominated by <em>Spartina argentinensis</em> (espartillo). Bioethanol production from this species would not change the current land use; it has been assessed using a consequential Life Cycle Analysis (LCA) methodology. LCA was carried out with comparative objectives with the fuel to replace (gasoline). The functional unit was defined as “The production and use of 1 MJ of liquid fuel”. Two impact categories were considered: (i) Climate Change and (ii) Energy Use through global warming potential and energy return on investment (EROI), respectively. Gasoline's GHG emissions were 96.9 g of CO<sub>2eq</sub> per MJ while the bioethanol obtained from espartillo was carbon negative in most scenarios. The EROI of gasoline had a value of 0.7 while bioethanol presented a range of 0.7 to 1.8. This LCA was realized with a consequential approach except for the by-products of fermentation at the biorefinery which were not considered to be used for any activity due to not having real data of such by-product; hence the obtained figures could be improved if these by-products were able to replace another product. The energy self-sufficiency of the plant and the avoided fires in rangelands are key factors to improve the environmental performance of bioethanol.</p></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"9 ","pages":"Article 100104"},"PeriodicalIF":0.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772801324000320/pdfft?md5=0b40aadb7ac0f2f03a61d8c3d69b2bf0&pid=1-s2.0-S2772801324000320-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142147787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
