Bread Making Process: Preferences, Baking Time, Experimental Design (Lab Report Sample)


THIs a lab report on the bread making process


In this study, the influence of temperature and ingredients composition on the baking time and taste of bread was investigated. The factors that were taken into consideration included salt, yeast, oil, sugar, and baking time. The outcome was analyzed through consumer taste feedback and the average time it took to bake the bread. 10 students were randomly picked from the school population and given questionnaires to fill regarding their taste preferences. The Experimental design was used to evaluate the variables of the experiment. It helped reduce the pressure on time, labor, and money, which are all limited resources. The results indicated that increasing the amount of the ingredients reduced preferences, while
the baking time increased when the temperatures were reduced.
Keywords: Limited resources, preferences, baking time, experimental design.
Bread is an essential part of meals consumed by families every day.For this reason, ways of making better quality bread have been devised. Since there is a big demand for bread, bakers have to deliver large quantities without compromising on quality. It is worth noting that various factors affect the production of bread. The standard ingredients include wheat flour, which determines the taste, softness, and freshness; yeast; the leavening agent that also converts sugars into carbon dioxide; salt, which helps in formation; flavor, and finally, water, which is a binding agent for all the other ingredients. There are also other inclusions that determine the different types of bread as regards to their flavor. They include fats, emulsifiers, dried fruit, ascorbic acid, and enzymes, among many others. The process of making bread starts with kneading. The process involves mixing all the ingredients to form dough, which should rise easily and give a high quality end product. Elasticity helps the dough hold in gases well during baking and also helps the bread keep its shape and cellular structure. In any economy, the bakery industry plays a significant role. Bakery does involve not only bread but also biscuits, muffins, cakes.and pastries. The demand for these products is high and brings in a lot of money. Many people are employed, and bakery-based multinationals are being established at a high rate. As much as this industry been growing, it also has had a fair share of challenges. For instance, quality raw materials are not always readily available, and people are, sometimes, ignorant of standards and end up supplying low quality and cheap products. The bakery industry is not an exception when it comes to trained personnel and observing the standard procedures of testing and sanitation. New technologies are invented day in day out and so technicians need to be up to date with skills on maintenance and repair of the machines.
In this experiment, various conditions were created and their outcomes evaluated. The experiment was structured such that the resources that were available covered most of the possible combinations of the ingredients. In this manner, it was possible to establish which factors had a major effect on the outputs.
Materials and Methods
The levels of the componentswere altered. The optimum of one ingredient was used while keeping the other at a slightly higher value. For example, for salt, the standard of one tablespoon was used while the other factor utilized two.
