The tubes were filled with 3 ml of their corresponding pH phosphate buffer. 10 drops of catechol and 10 drops of potato juice‚ which contains catecholase‚ were added to each of the seven tubes. The tubes were covered with Parafilm‚ stood for 5 minutes‚ and mixed every minute. After the 5 minutes‚ data was recorded based on the intensity of color with the “0‚+‚++‚+++”

EFFECT OF CARBONATION ON THE CHEMICAL COMPOSITION AND SHELF LIFE OF CARROT JUICE Abstract: Carrot (Daucas carota) is considered as important agricultural crop for human consumption. Carrot juice has very short shelf life and in this study the carbonation was carried out to study its effect on the shelf life‚ physic- chemical properties and the organoleptic properties. The carrot juice was prepared and its carbonation was done after carbonation different treatments were stored in colored and transparent

solution in each of the test tubes‚ respectively 23‚ 22‚ 20‚ 16‚ 8 and 0 drops of pH 7 buffer were added. 30 drops of potato juice containing the catechol oxidase enzyme were then added to the solution‚ and then timed for 5 minutes at room temperature. The pH treatment only required 5 test tubes‚ with 3mL of matching buffer (pH4‚ pH6‚ pH7‚ pH8‚ and pH10) in the appropriate tube. Following this‚ 10 drops of both potato juice and catechol are added to the tubes‚ and then timed for 5 minutes at room temperature

in potato juice extract Introduction The presence of quinones prevents infection of microorganisms because it is toxic to them (Danyk‚ H‚ 2013). Quinones are produced by the oxidation of phenolic compound of catechol. Enzymes are used to speed up chemical reactions in cells (Danyk‚ H‚ 2013). The enzyme catechol oxidase is used to speed up the production of benzoquinone which is to help in infection prevention. In this study catechol oxidase was combined with potato juice extract and

In the Penny Cleaning Lab‚ my hypothesis‚ which stated that the lemon juice would be the best at cleaning the penny since it is an acid and acids are particularly good at cleaning metallic substances‚ was indeed valid. First‚ we started out with 1mL solutions of all the substances in the test tray. We dipped the pH paper in each solution for about a second and recorded the pH level for each substance. Before starting‚ we noticed that all the pennies were in some shade of brown‚ which I predicted

The denaturing is done simply by the lowering of the pH of the milk by the addition of acid. Adding acid to the milk essentially unravels the proteins which leads them to band together into small clumps (Lawandi‚ Kitchn). These small clumps are the formed curds. The milk that does not clump together is the

experiment is to find out which liquid‚(orange juice‚ water‚ Coca-Cola‚ or Sprite)‚ dissolves Sugar Free Life Savers the quickest.I think the Sprite will dissolve the Life Saver the quickest because it has the highest acidity‚ with ph levels reaching 2.4. The ph scale ranges from 0 to 14. Battery acid reaches 0 on the scale. 7 is considered neutral. Sprite has a ph level of 2.4. Coca-Cola has a ph level of 2.5. Orange juice has a ph level of 3.5. And water has a ph level of 7.0. My materials for this

it can be used to find the ratio of sugar to acid. There are two methods specified for the determination of the titratable acidity of fruits: - Method using a coloured indicator; - Potentiometric method‚ using a pH meter‚ which should be used for very coloured juices. Material: - A laboratory burette of 25 or 50ml capacity or an automatic burette is used. A 10ml pipette‚ beaker (250ml)‚ a filter (muslin cloth or fine filter) and an extractor or homogeniser. - A bottle of distilled
