Alcoholic Beverages

Alcoholic beverages are an important part of the culture in many countries. The global alcoholic beverage market was recently valued at $1.439 trillion in 2017 and is expected to grow at a CAGR of 2.0% in coming years, with a projected value of $1.684 trillion in 2025.

Overview

Alcoholic beverages are an important part of the culture in many countries. The global alcoholic beverage market was recently valued at $1.439 trillion in 2017 and is expected to grow at a CAGR of 2.0% in coming years, with a projected value of $1.684 trillion in 2025. Much attention has been paid to the detection of the quality and safety of liquid foods because of their various raw materials. Certain types of liquid foods are very perishable. Along with processing techniques like drying, cooling, and freezing, there is also a need for rapid and cost-effective methods to analyze and classify quality, especially when considering the large amount of variability of liquid foods in the market. Moreover, consumer awareness of quality assurance amongst brands is a major factor in consumers’ decisions to purchase alcoholic beverages. The implications of poor product quality spreading in today’s social media environment, as well as the financial consequences of product recall, can be devastating to a company’s bottom line. Traditional methods for analyzing liquid foods include HPLC, GC, wet chemistry methods, and sensory analysis. These methods are time-consuming and expensive, especially when applied in an online setting. Developing rapid, non-invasive, cost-effective, and environmentally sound methods for quality testing has become a priority for alcoholic beverage manufacturers. One such method with potential for both laboratory and industrial testing of beverage products is NIR spectroscopy.

Process Analytical Technology (PAT) & On-Line Measurements

Process Analytical Technology is a framework for innovative process manufacturing and quality assurance. Critical points and parameters during manufacturing of a product are defined and the process is designed in a way that such points and parameters can be measured using analytical tools and instruments for real-time process feedback and control. Such instruments must be able to measure on-line and in a non-invasive manner. Many vendors have developed instruments that are able to measure multiple points in a process with a single instrument, usually using optical fibers and probes. PAT has become an important part of pharmaceutical manufacturing and is beginning to acquire a hold in the food & beverage industry. One such analytical tool with great potential for use in PAT is NIR Spectroscopy.

There are significant challenges to implementing PAT in a beverage manufacturing environment. NIR spectroscopy has been proven as a useful tool for measuring parameters of interest in edible oils measurement. Vendors are coming up with new and innovative ways to make on-line measurements a feasible solution for companies. Advances such as improved fiber-optics, in-situ sampling, a transition to integrated automation, improved data management systems, and communication systems in the Internet and Cloud age have all contributed to implementing PAT. The beverage and food industries also present particular challenges due to natural product variability. In the case of pharmaceuticals and chemicals, the manufacturing process is usually conducted in a controlled environment with constituents that rarely show variability in spectral data over time. For foods and particularly agricultural products, there can be marked differences in products due to many factors, such as temperature variability, seasonal variation, differences in soil and nutrients, and different breeds of the same product. Such variability is especially important to account for when performing coffee analysis. Such differences can create variability in spectral data that must be incorporated into calibration models for when calibrating NIR spectrometers and other analytical PAT tools. This is known as making models “robust” and often requires a larger and more incorporative sample set to achieve the desired results.

Calibration studies have been conducted for measuring parameters in Alcoholic Beverages on-line as well as in the laboratory. Results have been good and show that on-line measurements are a feasible tool for Alcoholic Beverages analysis using PAT. Full adoption of PAT in the Alcoholic Beverage industry will require a collaborative effort from process engineers, food scientists, and other contributors to provide the industry with a manufacturing framework for the 21st century.
