New Technical Quarterly Papers Published |
|
 "Are Plastic Bottles Ready to Replace Glass as a Beer Package?," by Roland Folz and Ruslan Hofmann, has been published in the MBAA
Technical Quarterly.
Abstract
Plastic containers and closures have taken on an increasingly important role as packaging materials for the brewing industry. Along with the many well-known advantages of plastic bottles, however, the inherent permeability of plastic to gases (O2 and CO2) is a problem. Brand owners who sell their beers through increasingly sophisticated and extended distribution channels are presented with a bewildering array of barrier enhancement technology options. Before deciding in favor of one barrier enhancement option over others to extend the shelf lives of their oxygen-sensitive products, brand owners must understand that there are hidden performance factors that can skew comparisons. The quality of barrier enhancement systems can be evaluated through the measurement of permeation. This paper introduces a new nondestructive, noninvasive measurement method for oxygen permeation and presents the results achieved using the method. The results show the importance of a reliable measurement system to gain knowledge about a barrier system, since the process of producing plastic bottles is complex and a thorough knowledge of all ingredients and process parameters is vital to achieving optimal results. Methods for benchmarking different bottle systems regarding beer shelf life and finding a maximum level of oxygen uptake due to permeation are introduced.
"Enzymatic Hydrolysis of Bitter Sorghum for Bioethanol Production," by E. D. Deenanath, S. E. Iyuke, and D. Lindsay, has been published in the MBAA
Technical Quarterly.
Abstract
The production of bioethanol derived from biomass and fermentation is becoming increasingly popular due to its application in the motor-fuel industries. The aim of the current work was to determine the amount of bioethanol that can be produced in a microbrewery from bitter sorghum grain using added commercial exogenous enzymes. A temperature-programmed mashing regime was carried out using a dual-enzyme combination (Cerezyme sorghum and Fungamyl 800L) for the hydrolysis of sorghum starch. For the fermentation procedure, ethanol production was evaluated by pitching the hydrolysate with either
Saccharomyces cerevisiae strain NRRL Y2084 or
Issatchenkia orientalis. Carbohydrates were analyzed by HPLC. Microbiological procedures such as plate counts and PCR were performed at the postmashing and postfermentation stages. HPLC analyses showed the presence of fructose, glucose, and maltose, indicating that bitter sorghum grain can be converted to fermentable sugars using the dual-enzyme combination. Maximum ethanol yield was 7% (v/v). Maximum ethanol was obtained on day 5 by
S. cerevisiae and day 12 by I. orientalis. Both yeast species were capable of fermenting the available sugars.
