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

The Geritol Solution What is the basis for Martin’s premise that seeding the ocean with iron would help combat global warming? The idea of stimulating plankton growth with iron grew out of the fertile mind of the late John H. Martin‚ an oceanographer at Moss Landing. Martin sought originally to explain a long-standing mystery concerning barren waters in the Antarctic‚ subarctic‚ and equatorial Pacific Oceans. With the abundant concentrations of nutritious nitrate and phosphorus in

Controlled Assessment: Osmosis of a Potato [pic] Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides. Biological membranes do allow water to pass through‚ but water will have no net movement unless osmosis takes place. Preliminary Method I have chosen to investigate the factor of the weight of potato strips after set amounts of time

A key component of the quantification of the protein concentration in the given samples was the generation of a standard curve. The data presented in Table 1 produced the graph in Figure 1 which was then used to calculate a line of best fit. The line of best fit yielded an equation y= 0.44976x which was in turn used to calculate unknown protein concentrations of given samples. The absorbances of the whole milk‚ cereal milk and muscle milk had been previously obtained and recorded via spectrophotometer

Twenty- one. A guard of the Tomb of the Unknown Soldier takes twenty-one steps during his walk across. This number alludes to the twenty-one gun salute‚ the highest honor given any military of foreign dignitary. The guards hold their task in their highest regards. They look their ability to guard the Tomb of the Unknown in highest regards. Similarly‚ it would be an indescribable honor for me to be able to lay the wreath upon the Tomb. Three reasons why it would be such an honor to be able to

Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

mass homicide took place inside the devils’ slaughterhouse;Concentration camps. Concentration camps were developed to ensure the mistreatment of Jews in places such as Auschwitz. To begin‚ “Concentration camps were established in 1933 for the confinement of opponents of the Nazi party” (Concentration Camp). Out of all of the people sent to concentration camps‚ Jews made up the majority. As the war progressed‚ three types of concentration camps came to exist. The first type of camps were prison camps

In this experiment‚ you will analyze a known solution that contains the entire Group I cations—silver‚ lead‚ and mercury (I)—and an unknown solution to determine which ions are present and which are absent. II. DISCUSSION: The chlorides of Pb2+‚ Hg22+ and Ag+ are all insoluble in cold water. They can be removed as a group from solution by the addition of HCl. The reactions that occur are simple precipitations and can be represented by
