Abstract

ABSTRACT: Vegetable and fruit waste are produced in huge quantities in the market. These wastes are also nutritionally very rich and, can be a viable option to be used as a substrate for the generation of value-added products. However, there is a need to characterize these wastes before using them as raw materials for the production of any value-added product. In this regard, the present study was taken up to determine the proximate analysis of vegetable and fruit waste. Proximate analysis is a way to determine the distribution of moisture, ash, volatile matter, and fixed carbon when the samples are heated under specified conditions. The discarded vegetable and fruit waste was collected from Kadi municipal vegetable market. The proximate analysis was carried out for 23 waste samples viz, 20 samples were a wet waste of individual fruits and vegetables and 3 samples were of consolidated sundried vegetable and fruit waste. Presented Proximate analysis of vegetable and fruit waste includes the determination of moisture, ash, volatile matter, and fixed carbon via standard test methods. The result revealed that for wet waste moisture content was in the range from 6.56 % to 77.57 %. Percentage of volatile matter was in the range from 8.06% to 86.46 %. Percentage Ash content was in the range from 1.32 % to 20.18 %.Percentage Fixed carbon was in the range from 1.76 % to 28.63 %. The moisture content in sundried consolidated waste was in the range from 5.83 % to 8.86 %. The percentage of the volatile matter was in the range from 62.06 % to 72.33 %. Percentage Ash content was in the range from 11.16 % to 12.83 %. Percentage Fixed carbon was in the range from 8.79 % to 16.27 %.
古吉拉特邦卡迪蔬菜市场收集的蔬菜和水果废物的近似分析
摘要:市场上产生了大量的蔬菜和水果垃圾。这些废物的营养也非常丰富,可以作为产生增值产品的基质。但是,在将这些废物用作生产任何增值产品的原料之前,有必要对它们进行特性分析。在这方面,本研究旨在确定蔬菜和水果废物的近似分析。近似分析是测定样品在规定条件下加热时水分、灰分、挥发性物质和固定碳分布的一种方法。这些被丢弃的蔬菜和水果垃圾是从卡迪市蔬菜市场收集的。对23个废物样本进行了近似分析,其中20个样本是单个水果和蔬菜的湿废物,3个样本是蔬菜和水果的固体干废物。介绍了蔬菜和水果废弃物的近似分析,包括通过标准测试方法测定水分、灰分、挥发物和固定碳。结果表明,湿废的含水率在6.56% ~ 77.57%之间。挥发分含量在8.06% ~ 86.46%之间。灰分含量在1.32% ~ 20.18%之间。固定碳含量在1.76% ~ 28.63%之间。干燥后的固结废弃物含水率在5.83% ~ 8.86%之间。挥发分含量在62.06% ~ 72.33%之间。灰分含量在11.16% ~ 12.83%之间。固定碳含量在8.79% ~ 16.27%之间。
