Evaluating the environmental impact of agri-food waste reduction: a bibliographic analysis and conceptual framework
No full textIncreasing concerns about the environmental impact of agri-food waste (AFW) have strengthened the need to assess the environmental performance of AFW reduction. Yet comprehensive literature reviews in this area remain scant. This paper presents a review of the research using a bibliographic analysis. Based on a sample of 171 research articles, we proposed a conceptual framework for evaluating the environmental impact of AFW reduction. The contribution of this review is threefold. First, a bibliographic analysis and semi-structured interviews are utilized to systematically review relevant literature and to propose a conceptual framework, which draws on existing research to determine ways of assessing the environmental impacts of AFW reduction. Second, our identification of four overarching research themes with respect to studies on the environmental impacts of AFW reduction offers fresh insights into AFW studies. Third, our conceptual model is refined following the semi-structured interviews we conduct, which serves to reveal the practical implications of our findings and research opportunities for the future.</p

Identifications of polyphenols and quantification of anthocyanidins in grapes and grape-derived products
No full textPolyphenols in grapes and grape-derived products have attracted public and scientific attention due to their numerous protective roles to human health. A rapid and comprehensive qualitative method was developed to characterize the different classes of polyphenols, such as anthocyanins, flavonols, phenolic acids and flavanols/proanthocyanidins, in grapes and grape-derived products. The detection was achieved by two runs with same HPLC gradient in different MS ionization modes and mobile phase modifiers (positive mode and 0.4% trifluoroacetic acid for anthocyanins and flavonols, negative mode and 0.1% formic acid for phenolic acids and flavanols). Under the optimized LC/MS conditions and based on the analysis of the MS and UV data and in comparison with the authenticated standards, a total of 53 polyphenolic compounds were successfully separated and individually identified including 33 anthocyanins, 12 flavonols, 4 phenolic acids and 4 flavanols/proanthocyanidins. With the method developed, a survey was conducted to qualitatively assess and compare the composition of polyphenols among 29 grapes and grape-derived products. To facilitate the quantitation of the major class of polyphenolic anthocyanidins, a simple and precise acid assisted hydrolysis method was established for the quantitation of anthocyanidins in grape juice samples, grape berries and grape skins using LC/MS. Five most common anthocyanidins of delphenidin, petunidin, cyanidin, malvidin, and peonidin in the hydrolyzed grape extracts were included in the quantification study. The validation of this method showed that the recovery percentages of five anthocyanidins ranged from 98.59 % to 103.20% with the relative standard deviation (RSD) less than 5.03%. The qualitative method provided complete insight into the composition of polyphenols in grapes, and other grape-derived products. This quantitative method provides a rapid and accurate tool to quantitatively study individual anthocyanidin in grapes or grape juice samples for quality control and to facilitate the evaluation and comparison of new commercial grapes or grape juice products in market.M.S.Includes bibliographical referencesby Yanping X
