食品加工剩余物板栗壳的利用研究进展

为了更好地对食品加工剩余物板栗壳进行开发利用，促进节能减排，综述了国内外最近20年在板栗壳资源化利用方面的研究进展，发现现有研究涉及将板栗壳作为生物吸附剂用于重金属污水处理、作为基质用于食用菌栽培和作为原料用于活性炭制备，以及从中提取天然色素用于食品着色和纺织品印染等方面，但这些研究并不系统，今后还需对板栗壳色素进行安全性评价，补充其毒理学和代谢方面的数据。板栗壳对重金属的吸附量偏低，有待于进一步通过理化改性提高其吸附性能，提取过色素的板栗壳残渣可进一步作为原料用于制备活性炭，以达到循环利用。

Review on Utilization of Chestnut Shell Residue from Food Processing

In order to better exploit chestnut shells which are residues from food processing,and to promote energy conservation and pollution reduction,the domestic and foreign research progress on the utilization of chestnut shell resource in the last 20 years was reviewed.The informed researches involved employing the shells as biosorbents for heavy metal removal from waste water,as substrates for mushroom cultivation,and as a material for activated carbon preparation,as well as for natural pigment production to color foods and dye textiles.However,these studies were lack of systematicness and some further researches should be conducted in future studies.The information on the toxicology and metabolism of the chestnut shell pigments should be given to evaluate their safety.The sorption capacities towards heavy metals of chestnut shell were low,and chemical modifications were needed to improve their sorption performance.The residue after pigment extraction could be further used as a raw material for the activated carbon preparation in order to achieve recycling.
