laboratory eight was to observe the affect of acid and alkaline cooking pH on pigments and textures of the vegetables(Yuan‚ 2014a) . Students were meant to gain experience on the different methods of processing fresh fruit and vegetables‚ both by observation and practise (Yuan‚ 2014a). The different methods were the effect of pH on pigment and texture of various vegetables‚ the effect that cooking procedures has on various pigments and flavours‚ the effect of sugar on texture and flavour of cooked fruit

this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment in chloroplasts. The chemical

Music Appreciation April 30‚ 2013 “The Separation” The separation of church music and secular music during the Baroque period was the beginning of something new. Many people had no idea that the instruments they used during the Renaissance period could do more than they had been doing with them. This brought a new meaning of music and life into the world. It was a great change for music‚ instruments‚ and even people. Church music‚ also known as sacred music‚ was well known in the Renaissance

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

1. INTRODUCTION SilCote aluminum pigment is manufactured by mixing aluminum paste with Monomer‚ SR-350 (trimethylolpropane trimethancrylate) and additive‚ Z-6040 which is an epoxy-functional Silane (3-glycidoxypropyl trimethoxy silane)‚ in a jacketed mixer with the presence of catalyst‚ ABIN (azo-bis-isobutyronitrile). White spirit‚ acts as the carrier solvent in the process. 2. PROCESS FLOW The aluminum paste is first loaded into the jacketed mixer‚ followed by introducing a pre-determined

on research and development have also become broader each day. Controversies have also emerged and one of the most discussed topics has been directed towards synthetic versus natural colorants. Food pigments are classified based on its origin or source; natural or synthetic. Synthetic food pigments are those substances that are needed to be tested for toxicity and allergenicity before

Plant Pigment Lab Question: What pigments are present in Red Wandering Jews? Background: A leaf is filled with many pigments. The pigments are usually masked by the prevalence of the green chlorophyll. Anothocyanin(red or purple)‚ carotene(orange)‚ and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram. What are
