Should Red Dye #40 be banned in the United States? Often‚ we don’t give much thought to the fact that much of what we consume is artificially colored. Red Dye #40‚ also commonly called Red 40‚ is widely used in the foods and drugs that we consume. Red food coloring is the most commonly used dye in the U.S.‚ according to Center for Science in the Public Interest (Carerra‚ 2013). In the food industry‚ red is a very appealing food color. The Food and Drug Administration approve it for use in candy

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

I. Problem: Will natural dyes from plants effective in producing colored paste? II. Title: Using Natural Dyes form Plants In Producing Colored Paste III. Introduction: Our project is made from the raw materials such as starch‚ alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue. It doesn’t cost us too much time because we can make this in a short period of time. IV. Review of Related Literature:

Krotec; Honors Bio Period 4 Photosynthesis Lab Report I. Introduction The photosynthesis lab is designed to quantify photosynthesis‚ enabling a number of variables to be tested for their effects on photosynthetic rate. The production of oxygen‚ is used as an indirect measure of photosynthetic activity.The lab allows the examination of the effects of different wavelengths of light on photosynthetic activity. The other aspect of the lab includes Paper chromatography‚ which is a useful technique for separating and identifying pigments and

Gas chromatography is the common method used for the biogasoline analysis. Biogasoline catalytic cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO)

Natural Dyes from Plants in Producing Colored Paste Abstract: Paste is a type of glue made from starch or dextrin‚ a starch product. This investigatory project shows that we can produce our own colored paste without spending much time and money and by performing simple steps. That’s why this Science Investigatory Project can help students save their money instead of spending it in buying expensive and commercialized colored glue. In addition‚ this colored paste can be an additional source of
