Use of Excel in food science 1: Linear regression

Abstract

Excel is usually included in the computer package as a part of Microsoft® Office. Almost everyone who deals with the experimental data is more or less familiar with the use of Excel. In food science, it is very common to use Excel to process, transform, sketch or define experimental data with any model. There is a wrong opinion as linear regression can only be used to fit a linear line to the data. However, a second order polynomial or a curved data could also be modelled by using the linear regression: if the model which is used to define the experimental data is linear according to its parameter(s), the parameter(s) of this model can be obtained by using linear regression. Regression application in data analysis tool in Excel could be used for linear models according to its parameters. The aim of this study was to show the application of models to the experimental data by using Excel with examples, where model parameters can be obtained by using linear regression. In the first example, using the linear model in Excel, the application of the data analysis tool on the microbiological data and the interpretation of the results were shown. In the second example, the application of a model that is not included in Excel but its equation is known by the user was shown to define the gas chromatography data. In the third example, the application of a model created by the user to define the microbial growth rate according to pH was shown. It is considered that this study would have important contributions for those working in the field of food engineering and food science.
