Abstract

In the present article we study the production of grape molasses. Data drawn from a specified biolaboratory, are properly analyzed in order to detect factors that affect significantly the Brix value and the volatile acidity of the final product. The ground that is used for planting and a variety of grapes have been taken into account. Off-line statistical quality control techniques have been employed and the outcomes are displayed and discussed in detail.

Highlights

Statistical quality control is a useful tool for ensuring that the quality characteristics of a product are at the nominal or required levels and consists of a set of statistical methods for analyzing data
The present study focuses on the quality improvement of the final bioproduct by examining the effect of some qualitative characteristics to volatile acidity and Brix value of grape molasses
Methods of Statistical Quality Control are applied in order to determine the appropriate measures of noise and target, while based on the proposed measures, we shall appraise those factors that contribute significantly to the variability and central tendency of the volatile acidity and Brix value of the final bioproduct

Summary

Introduction

Statistical quality control is a useful tool for ensuring that the quality characteristics of a product are at the nominal or required levels and consists of a set of statistical methods for analyzing data. The present study focuses on the quality control of the production process of a biological product called grape molasses (or petimezi). This product is made by 100% biological grapes, without using any pesticides. Throughout this paper, a laboratory located in Peloponnese of Greece, which produces grape molasses by using 100% biological raw material, is under investigation. The company incorporates a production unit of biological grape molasses and carries out products delivery in Greece and other countries.
