【摘要】：近几年,市场上具有高营养医疗保健价值的山核桃频频出现质量问题。而传统的质量控制方法并不能满足山核桃“从山头到餐桌”的全程质量控制。通过比较研究发现,当前质量控制方法均偏重生产加工环节,侧重于事后预防而非事前控制,已有控制方法落后,抽样检验方法单一、表现形式单一,多以合格率的形式反映质量现状。 21世纪是大数据时代,一切用数据说话。面对目前山核桃质量控制数据的缺乏,本文旨在获取统计数据,应用统计数据来进行山核桃质量管控。本文首先采用实地调查法与实证分析法明确山核桃的生产链条、生产流程及质量影响因素。继而采用比较研究法,对当前食品质量控制措施,尤其是统计方法,进行了比较分析。在此基础上,探索了相关质量控制体系、系统、方法在山核桃质量控制中的应用,并基于此筛选、设计合适的统计方法,首先构建山核桃质量控制指标体系,覆盖山核桃质量控制全程,并将全程分为产前、产中、产后三个环节,分环节分别探索了污染指数法、质量控制图、工序能力指数、变异度、工序变化假设检验、分级、多指标综合评判等统计方法在山核桃质量控制中的应用,设计了相关数据获取表格,详细说明了在山核桃整个生产价值链条中的应用,辅助于全程产、供、销一体的抽样检验方案,最终形成基于统计方法的山核桃全程质量控制框架体系。可以有效获取相关质量监控数据,并高效利用数据。 本文对质量控制所设计的统计方法覆盖了山核桃“从山头到餐桌”全流程,做到了以事实和数据说话。切实保证山核桃质量安全,促进山核桃产业发展及森林食品行业壮大。
[Abstract]:In recent years, pecan with high nutritional and health care value appears quality problems frequently in the market, but the traditional quality control methods can not meet the whole quality control of Pecan "from the top of the hill to the dining table". Control, the existing control methods are backward, sampling inspection methods are single, the manifestation is single, mostly in the form of qualified rate to reflect the quality status quo.
The 21st century is the era of big data. Faced with the lack of quality control data of hickory, this paper aims to obtain statistical data and use statistical data to control the quality of hickory. On this basis, the application of relevant quality control systems, systems and methods in pecan quality control was explored. Based on this screening, suitable statistical methods were designed. Firstly, the quality control index system of Pecan was constructed. The whole process of quality control of Carya cathayensis was divided into three stages: pre-production, mid-production and post-production. The application of pollution index method, quality control chart, process capability index, variability, hypothesis test of process change, classification and multi-index comprehensive evaluation in quality control of Carya cathayensis was explored in different stages. The application of the form in the whole production value chain of hickory is explained in detail, which is helpful to the sampling inspection scheme of the whole production, supply and marketing, and finally forms the whole quality control framework system of hickory based on statistical method.
The statistical method designed by the quality control institute covers the whole process of hickory "from the top of the hill to the dining table". It can guarantee the quality and safety of hickory and promote the development of hickory industry and the growth of forest food industry.
