Complete the Chemistry of Pectin lab exercise and then answer the following questions. 1. What is the difference between jam, jelly and fruit preserves? The three points of differentiation are the type of fruit, how it is prepared and the proportion of ingredients. Jams are made of crushed fruits which are cooked with pectin, sugar [and maybe lemon juice to change the pH and cause the jam to become more solid] until the mixture thickens to spreadable consistency.
The ice which is going from solid to liquid, is absorbing the heat energy from the other ingredients/ice cream. In addition, the ice is sprinkled with rock salt, which lowers the freezing point of the ice. The freezing point being when a substance becomes solid. When the ice melts, even more heat is absorbed from the the ice cream mixture. All of the heat that the ice absorbs makes the ice melt, lowering the freezing point;meanwhile, the ice cream mixture is changing from a liquid phase to the more solid form, ice cream.
Choosing from the type of fruit, cookie, wafer stick and the type of syrup one would prefer from a caramel, chocolate, or nutella basically whatever one would prefer is what they had.

Cream liqueur is also made composes of several other added ingredients which may include sugar, full fat milk powder, non-fat milk solids, sugar, flavourings, colouring, preservatives and a thickening agent such as sodium caseinate, which also acts as a stabilizer to prevent the cream and alcohol from separating. The addition of trisodium citrate is to further improve stability Range of composition of a standard cream liqueur Component Composition ( wt %) Milk fat 12-16 Added sugar 15-20 Sodium Caseinate 2.6-3.5 Non- fat milk solids 1.0-3.5 Ethanol 14 Water 46-51 From research it 's proven that a number of problems can be encountered when using conventional agitators such as the blender used in the lab. (silverson.com, 2014) • Long mixing times are required to completely wet out, disperse and/or dissolve the ingredients. • Sodium caseiante and milk powder are very cohesive and have a tendency to form a large mass which blenders cannot easily break down into a solution. • Caseinates are difficult to dissolve and will rapidly increase in viscosity, especially if added directly to the cream.
2 tablespoons of chickpea flour, 1 tablespoon of milk or cream, 1 teaspoon of turmeric. Take all the ingredients and mix them into a fine paste. Apply it all over your face and leave it for 15 minutes. Then, gently scrub it with a soft facial pad or a cloth dipped in light lukewarm water.

On a glass slide, 1 drop of distilled water was placed. Then, a loop-full of culture was transferred on the slide and it must be spread. It is then allowed to dry. Then, the smear must be heat fixed by exposing it to flame for few times until it got fixed. It is to prevent the cell from washing away during the staining and washing process.
Fold the double stack in half so you have a nice looking 4-layer stack of cheesecloth. Line a good-sized bowl with the cheesecloth and pour the delicious contents of the blender into the center. Quickly hold the edges of the cloth together in one hand and use the other hand to gently twist and squeeze the bundle to extract all the delicious juice from the pulp. We advise you to wear a pair of rubber gloves if you don’t want the juice to stain your
3.10.2Column Packing Before starting to pack a column, a small piece of cotton is gently will insert into the centre hole of column with the aid of a long stick. A small amount of n-hexane will add into the column. Silica gel weighted is mixed with n-hexane to form a mobile slurry solution and then slowly transferred into column. The side of the column will gently tape to prevent the formation of air bubbles in the column. Additional solvent will use to add the remaining silica gel into the column.
