Nurul Ain O, Marina AM, Sakinah H. The effect of avocado puree as fat replacer on the physical quality of muffin. Malays Appl Biol. 2016;45(2):11-16. Accessed March 23, 2020. https://www.researchgate.net/publication/312016837
Concerned about the amount of trans fatty acids and saturated fatty acids that lead to life threatening illnesses, the researchers sought to reduce fat in a muffin with avocado puree. There is a very detailed account of the recipe preparation, including the different percentages of avocado puree used in each batch as a replacement for butter. The muffins were measured, analyzed for texture and color then the data was put through a statistical analysis program. The results showed that overall the avocado did not affect the batter in any way. The muffins had a high water content, but there was no difference in their chewiness, crumb factor, or hardness. The avocado did change the color of the muffins, however. In the end, the avocado was deemed a suitable fat replacement, but the researchers suggested that further testing should look at shelf life and sensory perception to see if this substitution is practical and acceptable to consumers.
When researchers begin to think about a topic to study, they spend some time finding out what has already been studied in their area of interest. They search for articles and reports that provide information on the history, background, key findings, related issues, and knowledge gaps related to their research.
Understanding what information is already out there on a topic helps the researchers focus their own study while placing it in the proper context of current and past research. This process is the literature review. The researchers are going over what has already been written on their topic.
Usually, when they are publishing the results of their own study in a journal article, the researchers begin with a short literature review which now provides background and context for the readers, helping them to understand the relevance and importance of the current study.
