Waste generation in the acquisition of vegetables in nature and minimally processed by nutrition and dietary service of a public hospital

Abstract Meal production activities are responsible for the environmental impact. This study evaluated waste generation from the acquisition of vegetables in nature and minimally processed vegetables (MPV) for meal supply in a Nutrition and Dietetics Service of a federal public hospital. It is a cross-sectional descriptive, retrospective study, of quantitative character, with secondary data considering 2016 and the first semester of 2017. As a result, the estimated monthly mean of waste generation from non-edible parts of fruit was 5545.8 kg, corresponding to 34.2% of the total acquisition of 2016. Data from the first semester of 2017 showed an increase of 3.7% higher than the 2016 average. In the evaluation of vegetables, MPV acquisition by the study period projected a non-waste generation of 73,8 tons. If these vegetables were bought in nature would be necessary more 25.6% of raw material in 2016, and in the first semester of 2017. The results of the present study showed that MPV acquisition becomes an alternative for food and nutrition services.

【摘要】膳食生产活动是环境影响的重要来源。本研究针对某联邦公立医院营养与膳食科用于膳食供应的天然蔬菜与最低限度加工蔬菜（minimally processed vegetables, MPV）的采购所产生的废弃物情况展开评估。本研究为定量性质的横断面描述性回顾性研究，采用2016年及2017年上半年的二手数据开展分析。结果显示，2016年果蔬不可食用部分的月均废弃物产生量估算为5545.8千克，占当年总采购量的34.2%；2017年上半年的数据显示，该数值较2016年的月均水平提升了3.7%。在蔬菜类采购评估中，研究周期内采用最低限度加工蔬菜（MPV）采购模式，预计非可食用废弃物产生量为73.8吨；若在2016年及2017年上半年改用天然蔬菜采购，所需原材料量将增加25.6%。本研究结果表明，最低限度加工蔬菜（MPV）采购可作为膳食与营养服务的可选方案。
