Monitoring O2 and CO2 Fermentation Processes

ByAdmin 16 August 202216 August 2022

Fermentation หรือที่เราเรียกว่ากระบวนการหมัก มันคือการทำให้ยีสต์หรือเอนไซม์ เติบโตในปริมาณที่พอสมควร เพื่อให้เกิดความเปลี่ยนแปลงทางด้านรสชาติ เนื้อสัมผัส หรือแม้แต่กลิ่นของอาหาร ซึ่งในการหมักนั้นไม่มีอะไรสำคัญไปกว่าอาการควบคุม Nutrition และ อากาศ

Fermentation processes are used in the manufacturing of countless products from simple yeasts to complex enzymes and pharmaceutical products.  Without fermentation we would have very few of the modern foods and health products we have come to enjoy.  There are a very large number of manufactures involved in fermentation around the world.

All fermentation processes require the active culturing of live biological components in various types of growth media.  The control of the growth of these cultures provides the desired end products.  Proper control of both liquid nutrients and atmospheric gas levels are important to these processes.

There are two basic types of fermentation; aerobic and anaerobic.  In aerobic fermentation air is forced into the reaction vessel (fermenter) to provide the cultures with needed oxygen.  The air is not cut off to the process until it is completed.  Oxygen is converted into CO2 by the cultures during the process and is released.  CO2 levels will rise in the fermenters, but not to extreme levels, because the air is being continually replaced.

In anaerobic fermentation the air flow and corresponding oxygen level is controlled more closely.  In some cases the reactor may be sealed and the initial headspace in the vessel provides all necessary oxygen.  During the process of fermentation the oxygen level drops and the CO2 rises with time.  Eventually, the cultures stop growing.  This is due to their O2 supply being depleted or they produce the desired end product because their O2 supply is artificially lower than would be found in ambient conditions.

Manufacturers involved in fermentation will have interests in monitoring the O2 and CO2 levels in their reactor vessels during these processes.  This is particularly important in anaerobic processes because the yield of the reactor will be directly proportional to the ability to maintain desired O2 and CO2 concentrations during the fermentation cycle.

Fermentation processes off-gas hydrocarbons and this renders zirconia analyzers useless.  To properly handle oxygen requires an electrochemical analyzer that is unaffected by CO2.  We have a combination electrochemical O2 and CO2 analyzer that can effectively handle the fermentation process. โดยที่กล่าวมาทั้งหมดนี้ ถ้าเราควบคุมปริมาณออกซิเจนและคาร์บอนไดออกไซด์ ให้อยู่ในระดับที่เหมาะสมเท่านั้น จึงจะเกิด fermentation process ที่สมบูรณ์ได้  สิ่งที่ต้องระวังใน Fermentation Process ก็คือ ความชื้นที่ถูกผลิตขึ้นมา ในปริมาณมากระหว่างกระบวนการหมักซึ่งอาจจะทำให้เกิดการควบแน่น และทำให้สินค้าเสียหายได้ ปรึกษากับทีมงานของ Tasatec ได้ค่ะ สำหรับลูกค้าท่านใดที่กำลังดูเรื่อง O2/ CO2ol ใน Fermentation Process
