Chemical And Sensory Evaluation Of Peanut Butter

Abstract

Chemical and sensory evaluation of peanut butter using two varieties of peanut (arachis hypogea)
Two varieties of peanut (Arachis hypogea) used for peanut butter making are Valencia from Gombe in Northern part of Nigeria and Virginia from Ogoja in cross-River state of Nigeria. The peanut butter obtained was evaluated chemically and sensually to determine the variety that performed better. Proximate analyses were carried on the samples. The result of there analyses showed ash 5%, moisture 4.5%, and fat 40%. The properties evaluated include fixture, consistency. The organoleptic properties evaluated for are flavour. The Virginia (ogoya) variety is more acceptable than the Valencia (Gombe). This project has proved that peanut butter making is technically possible.

1.0 INTRODUCTION
Peanut butter is by far the most important product made from peanuts in the United States.
While there are several types of wild and cultivated kinds, the peanut (groundnut, earth – nut, monkey nut, goober, pinda, pinder, manilla nut) that we know is the fruit or pod of Arachis hypogea belonging to family of leguminous. The flowe is Horne above ground and after it withers the stalk elongates, bends down and forces the ovary under ground. The seed matures below the surface and the plart favour light sandy soil. When the seed matures the inner linning of the pods, or seed coat, changes from while to brownish. The entire plant, including most of the roots, is removed from the soil during harvesting. (wood root 1973).
In the manufacture of peanut butter, the nuts are roasted, cooled and ground along with salt and suger to a very smooth fexture and consistency. (muller 1988.)

1.1 THE OBJECTIVE OF STUDY
The aims of this research are to evaluate the chemical and sensory properties of peanut butter and the identify the best variety of groundnut for peanut butter manufacturing.

Research Guidelines

The Title Page should be the first section of your project “Chemical And Sensory Evaluation Of Peanut Butter”, providing essential details like the project title, your name, your supervisor’s name, the institution, and the submission date. After that, the Abstract offers a brief summary of your project, touching on its purpose, methods, results, and conclusions in 150-300 words. The Acknowledgments section is where you can thank those who supported your research, such as your supervisor, peers, or organizations that provided resources.

Next, the Table of Contents organizes the Chemical And Sensory Evaluation Of Peanut Butter by listing its chapters and sections, along with page numbers for easy reference. The List of Figures and List of Tables help guide readers to specific visual elements like graphs, charts, or tables included in the document. There should also be an Abbreviations and Glossary section to explain any specialized terms or acronyms, making the content clearer to readers unfamiliar with the technical language.

The main body of the Chemical And Sensory Evaluation Of Peanut Butter should start with the Introduction, which provides background information, outlines the research problem, states your objectives, and gives a brief overview of your research methods. Following that, the Literature Review offers an in-depth look at previous research relevant to your project, identifying gaps your study aims to address. The Methodology section then explains the research design, tools, and data collection methods you used to conduct the project and analyze the data.

In the Results and Discussion section, you present your findings and discuss them in relation to the Chemical And Sensory Evaluation Of Peanut Butter research questions or objectives, often using tables or charts to help explain the data. The Conclusion summarizes the key results, discusses their implications, and suggests possible directions for future research. You may also include recommendations based on your findings, offering practical advice for improvements or applications. Finally, the Chemical And Sensory Evaluation Of Peanut Butter project should include a References or Bibliography section to list all the sources you cited, as well as Appendices for any additional material. A Statement of Originality is often included to confirm the authenticity of your work
