Concentration of liquid foods is a fundamental operation in many food processes; it is completely different from dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum

Biodegradable plastic from cornstarch ABSTRACT The study aims to produce biodegradable plastic using cassava starch as its main component. Cassava starch was mixed with water‚ cornstarch and cooking oil INTRODUCTION There is an increasing demand for plastic‚ from the highly technological fields of electronics‚ fiber optics‚ and pharmaceuticals to the basic necessities such as sandwich wrappers and garbage bags. This high demand for plastics‚ however‚ has been a major contributor to

The Dachau Concentration Camp was the first camp established in March 1933.It became the first concentration camp made by the Nazis. It was placed by a munitions factory by the city Dachau. It is nearly 10 miles from Munich‚ Germany. In the first year there were 4‚800 prisoners. The first prisoners were German Communists‚ Social Democrats‚ Trade Unionists‚ and other opponents of the Nazis. During 1937 the SS made the prisoners construct a large group of buildings on the grounds of

during the Holocaust was the concentration camps. Many people were affected by the reality of what was happening in Germany. Within Germany‚ there were types of camps that people could be sent to: concentration camps‚ labor camps‚ extermination camps and prisoner-of-war camps. Concentration camps were the Nazis’ way of imprisoning the Jews‚ political antagonists and other people deemed socially unacceptable of the country. If these people were sentenced to a concentration camp and did not arrive

A concentration camp is where prisoners of war‚ enemy aliens‚ and political prisoners are detained and confined‚ typically under harsh conditions‚ or place or situation characterized by extremely harsh conditions. The first concentration camps were established in 1933 for confinement of opponents of the Nazi Party. The supposed opposition soon included all Jews‚ Gypsies‚ and certain other groups. By 1939 there were six camps: Dachau‚ Sachsenhausen‚ Buchenwald‚ Mauthausen‚ Flossenburg

attempting to “Remain loyal to their homeland” and were acting as spies. Even without concrete evidence‚ President Roosevelt signed for them to be relocated. These camps were still located on American soil and were not death camps. The camps were concentration camps‚ a place where they go to basically do hard labor all day. Many Japanese American families sold their homes and assets‚ there was no guarantee that their lives would continue as normal upon their return. Their homes sold for fractions of

Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for

Title of Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction

monosaccharide reducing sugar (Kolej Mara Banting – Students’ Handbook for Biology HL Year 1). It is the simplest form of carbohydrate. In this experiment‚ sulphuric acid‚ H2SO4 and potassium permanganate‚ KMnO4 is added into glucose with different concentration and the time taken for the purple pink colour of potassium permanganate solution to change to colourless is recorded. This is because glucose donates electrons to the permanganate ions‚ causing it to change colour (Kolej Mara Banting – Students’

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls
