GGC UNDERGRADUATE RESEARCH ENCOUNTER вЂ“ CHEM 1211K
QUALITATIVE ANAYLYSIS OF FOOD DYES
Recently we will begin focus on a class project toВ conduct an investigation of meals dye artificial additives. Your involvement in the project will continue throughout this semester and in addition through Chem 1212. В Our overall goal in this year is to determine the identity of the dyes in several foods and then to quantify the amount of absorb dyes contained in these foods. В Building on the base you establish, the projectВ will hopefully continue for several years. Therefore- you have an obligation to contribute your ideas within a thoughtful, serious and scientific way. Please do the ideal job you may to make sure you collect valid information, be familiar with experimental types of procedures, and perform those types of procedures accurately! В This is a classic research project in this none individuals knows the best strategies for conducting the project or the actual outcomes will probably be. You will begin wherever responsible chemists generally begin a new task вЂ“ with a search for information on food color additives. В В Presently, there are issues about the application of food chemical dyes and other chemicals. Food dyes have been related to conditions including ADHD, over activity and severe allergies. While thirty years ago one did not conceive of food becoming labeled with caloric and also other nutritional info, it is common nowadays. One can possibly envision long term labeling which will extend to quantitative numbers of food dyes present. В В The research project being undertaken simply by GGC as well as chemistry college students will be completed over days. During the 1211 semester learners will:
Week 1: College students will gain experience in searching the scientific books and gather background information around the extraction and qualitative evaluation of food dyes.
Week two: Students will select a foodstuff on which to undertake their research. Students will then perform tooth extractions and analyses to determine the foodstuff dye(s) within their sample. The main identification of food dyes will be accomplished using UV/VIS Spectroscopy. Groups will carry out extractions/analyses in food types of other clubs for the purposes of " peer reviewвЂќ.
Week 3: Students will complete their research laboratory report inside their lab take note books pertaining to the instructor to evaluate. Teams will then prepare mouth presentations which includes Introduction, Treatment, Data/Observations, and Conclusions. Peer-evaluation/comparison will also happen.
Through the 1212 session students will certainly expand upon the progress made through the 1211 term. In addition to qualitative examination, they will also execute a quantitative evaluation to determine the amounts of food dyes present. Although an common presentation to be used to share results in 1211, the students is going to prepare a written presentation within a format ideal for publication within a scientific record.
WEEK 1: BACKGROUND RESEARCH IN FOOD CHEMICAL DYES
Objective: To build up research and library abilities in order to attain background information in food dyes that will direct and guidebook your investigation into their qualitative and quantitative analysis.
