What conditions are the most favourable for microbial food production?
Humidity of yeast as yeast is able to perform more optimal as humidity is able to affet the fermentation of the yeast (The Importance of Humidity Control in Bakeries 2022)
This is the optimal growth of yeast as it is able to ferment as it is able to reproduce and grow at this temperature
This temperature is close to the dying point of yeast as yeast dies at 60*c which could be tested to see how much of a difference that over heating is compared to optimal and low temperatures
Unlike a high temperature yeast is able to bloom however not optimal which can be tested how different temperatures are able to determine which conditions are most favourable for food production
Amount of glucose
Which is the most optimal for amount of glucose to make it produce most carbon dioxide?
Research has stated that some types of yeast are able to survive high concentrations of glucose solution and by investigating
Neutral is inbetween acidic and alkaline which could be investigated to investigate the most effective growth of yeast
Yeast is not able to grow optimally under alkaline conditions unlike acidic conditions which it can grow optimally in (Tudor & Board 1993)
The optimal point for yeast to grow is 4.0-4.5 and are able to grow well in acidic conditons as yeast is usually acidiphilic(Tudor & Board 1993) (Narendranath & Power 2005)
Best tasting bread (qualitative data)
Which bread has the most holes
Production of Carbon Dioxide
what conditions creates the most carbon dioxide?
Carbon dioxide is produced during aerobic respiration as the microbes feed off oxygen which produces carbon dioxide and water which can be measured through carbon dioxide detector
Production of Ethanol
what conditions creates the most ethanol
Ethanol is produced during anareobic respiration when there is a lack of oxygen which can result in an independent variable of oxygen as oxygen levels to see which oxygen level is optimal for the production of ethanol detector
It is the most common type of yeast used in cooking due to being widely available how ever can easily be killed if the temperature is too hot or if the temperature is too cold it will not be optimal for bloom (Types of Yeast and Which One To Use When - Seasons and Suppers 2020)
