“…This study showed that pyridoxine and folates dissolved easily during the brewing process and remained in the bottled beer. Despite different starting levels of these vitamins in the three brews due to different malts used, comparable trends were observed during small and large scale brewing processes because both plants used similar unit operations to obtain the final products ( 25 ) . Fermentation increased vitamin content more significantly than the other brewing steps; moreover, comparable trends were shown for all the three beers studied, independently of the fermentation systems (top and bottom).…”

Pyridoxine and folates during small and large scale brewing

Beer contains the vitamins pyridoxine (B6) and folates (B9); their content is variable and depends on several factors. The aim of this study was to investigate the level of these vitamins during large and small scale brewing so as to identify the steps that can influence their levels in the final product. A Golden Ale and Scottish Ale were brewed at sales gravity in a 12 hL plant and a Gold Lager from a bottom fermented high gravity wort at a commercial scale. The levels of pyridoxine at mash‐in differed between the brewing processes, due to the different malt used. Pyridoxine levels decreased during mashing while the pyridoxamine concentration remained constant. Although an increase of pyridoxine was observed after the fermentation, its level decreased in the final beers from the large scale process reflecting dilution and pasteurisation. With regard to folates, the levels increased during mashing, decreased after wort boiling and increased during fermentation. This study showed that both pyridoxine and folates were solubilised during the process and remained in the final product. © 2021 The Institute of Brewing & Distilling

“…Another approach regarding the simulative investigation of the refrigeration demand during fermentation using multiagent systems is described by Howard et al [26]. A holistic hybrid approach, which covers several areas of the brewery, is described by Hubert et al [27]. They present a simulation, also based on reference nets and Java programming, in the form of balance flows including factors such as the chemical oxygen demand of wastewater and energy management.…”

Simulation of Energy and Media Demand of Batch-Oriented Production Systems in the Beverage Industry

et al. 2022

The global brewing industry is facing enormous environmental challenges and is urgently required to produce sustainably and efficiently. The rising costs of energy and electricity are forcing small and medium-sized breweries in particular, which are confronted with barriers such as lack of capital and know-how, to make substantial changes. This article presents an extended approach to prognose the energy and media demand for batch-oriented production of a brewery. Therefore, based on a modeling editor as well as a standardized data structure and an approach to determine the simulation-relevant parameters, a solution for fast and easy model generation was developed. Extensive measurement recordings within a brewhouse were performed to create a comprehensive model with recipe-specific parameters and detailed production plans. A simulation model can be generated automatically from a configuration file in a simulation environment that has been extended to include the mapping of batch-oriented operation. A validation is presented and a maximum deviation of the electrical and thermal energy demand of 1–2% is achieved. In combination with a preliminary work, the holistic simulation of the complex combined production of batch-oriented and discrete operation within the brewery is presented and allows comprehensive analysis as well as optimization towards sustainable production.

Due to economic, social and technical trends, as well as rising energy costs, the food and beverage industry is challenged to work energy‐efficiently. Small and medium‐sized enterprises in particular lack of both time and knowledge to identify and implement suitable energy efficiency measures. With the help of simulation, decision‐makers can pursue numerous approaches and make well‐founded decisions. A metamodel based on four modeling pillars (physical‐, process‐, article/recipe‐, and production plan model) for an entire production system concerning the forecast of energy and media consumption is presented. The metamodel is implemented in a user‐friendly modeling tool, which enables a simple hybrid modeling without prequalification of the user. Subsequently, a standardized data exchange file, as basis for a simulation model, is generated. For validation, various use cases were modeled and the tool was validated using a systematic test. In addition, two simulation studies were performed to show that the presented approach provides the opportunity to create a holistic model in terms of forecasting energy and media consumption.
