  1. Taking hops beyond the brewing industry William Popa Beta Tec hop products

  2. CO2 Extract is separated into the following fractions at the ISO- Plant Essential Oils Flavor Foam Color

  3. Where are Hop Acids being used? Hops 2o 1o Hop Extract 2o 1o Alpha Acids Beta Acids Brewing Products Ethanol & Spirits Sugar Animal Feed Nutraceutical

  4. Effects of Hop’s on the Bacterial cell wall Hop acids lower the cell ph and stop the glucose uptake Normal Bacterial cell wall

  5. Results: IsoStab StudyPart 1 Prepared by Biotechnology Resource Center University of Minnesota for BetaTec, Inc. May 5, 2005

  6. Minimal Inhibitory Concentrations of IsoStab against Lactobacillus species and Ethanol-Production strains of Saccharomyces cerevisiae It is clear that the growth of all three strains of Lactobacillus are inhibited by 6ppm of IsoStab. At the recommended concentration of hop acids to be used during ethanol production from corn mash (30ppm) the Lactobacillus species chosen are inhibited from 75-91%.

  7. The data presented shows that up to 200 ppm of IsoStab has virtually no effect on the growth of the six yeast strains. At 300ppm to 400 ppm, a slight reduction in growth can be observed and at 500ppm, at least 2 strains show a significant reduction in growth. The Effects of High Concentrations of IsoStab and Yeast

  8. Data Page from In-Plant Testing on Corn MashFebruary 2005

  9. Summary of IsoStab Batch Plant Test Data March 2005 The corn mash had a pH of 5.8. Some yeasts will increase Lactic acid and glycerol levels when they are in a healthy state.

  11. Summary of IsoStab Batch Plant Test Data February 2006

  12. Summary of IsoStab Batch Plant Test Data February 2006

  13. Conclusion: The results from this trial are very positive and indicate that IsoStab is an effective product to inhibit lactic acid and acetic acid formation without affecting yeast. In-fact, yeast during the treatment was healthier as indicated by higher viability numbers through out the fermentation train.

  15. IsoStab“The natural antibacterial control agent” IsoStab is a standardized 30% aqueous alkaline solution of isoalpha acids. Patent pending for IsoStab. IsoStab can effectively control the growth and/or kill gram- positive bacteria commonly found in fermentable solutions such as Lactobacillus brevis and Lactobacillus fermentum. IsoStab is food grade “GRAS” FDA and is Kosher certified can be used to make spirits, ethanol and food grade yeast. IsoStab is very soluble and is ideal for dry-mill fermentations containing high solids.

  16. Lactic Acid Concentration 0.01 To 0.15% 0.15 To 0.25% 0.20 To 0.35% 0.35 To 0.45% 0.45 To 0.70% IsoStab Treatment Levels 10 to 35 ppm 30 to 45 ppm 35 to 45 ppm 45 to 55 ppm 60 to 90 ppm Normal Treatment Range for IsoStab in Corn Mash at a Batch Plant is 30 - 60 ppm

  17. What is possible when you use IsoStab ? • Your plant efficiency will increase • Your Acetic and Lactic acid level will be controlled • IsoStab is Kosher Certified & Gras / FDA • Hop’s are listed in the AAFCO as a feed ingredient • Your DDG will be antibiotic free • You can sell your DDG to Europe, McDonalds, Burger King and to the Chicken Industry in the United States. • IsoStab is a Yeast enhancer • Faster fermentations

  18. What would be the impact on your DDG if you used IsoStab? • John I Haas, Inc. has be granted the patent for Hop Acids to be used in cattle feed – A method of using hop acids for increasing food and energy uptake from feed by livestock – Hops increase the production of propionate and lactate and decreasing the production of methane

  19. Today in the United States Ethanol Industry • Beta Tec has over 45+ customers using IsoStab daily • Both continuous and batch plants using IsoStab • Beta Tec is currently adding new technical sales positions • For more information: www.bthp.info • Contact: William Popa (Bill) at 816-509-0200
