Juice Concentrate Industry Juice is a liquid that is naturally contained in fruit and vegetables. It is commonly consumed as a beverage or used as an ingredient or flavouring in foods. Juice is prepared by mechanically squeezing or macerating fruit or vegetable flesh without the application of heat or solvents. For example‚ orange juice is the liquid extract of the fruit of the orange tree‚ and tomato juice is the liquid that results from pressing the fruit of the tomato plant. Common methods for

Page 1 of 4 Expansion Devices I. Introduction Expansion devices are basic components of a refrigeration system which carry out two major purposes: (1) the pressure reduction from the condenser to evaporator pressure and (2) the regulation of refrigerant flow into the evaporator. These expansion devices can be generally classified into two types which are namely the fixed opening type (flow area is fixed) and the variable opening type (flow area changes correspondingly with a change in mass

project‚ we recommend the following: 1. Gather as many seeds as you can to extract a larger amount of vegetable oil. 2. Dry the seeds to yield better quality oil. 3. The making of the paper was made with the use of a Soxhlet Extractor and a Rotary Evaporator; therefore future researchers must follow carefully the right procedures. Abstract The purpose of this study is to determine if there is a significant difference between our product and the commercial one. This research is aimed to provide

Abstract In the asymmetric synthesis of (S)-Ibuprofen‚ the compound is synthesized in nonracemic form directly from an achiral precursor. First‚ racemic ibuprofen was converted to aN achiral ketene via the acid chloride by adding thionyl chloride followed by triethylamine. Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides

HCO3-‚ Cl- is extracted using Pasteur pipet. Dry the product with CaSO4 thoroughly. This step is important because if there’s any water residue left‚ it will show when drying ether at rotary evaporator step. Also‚ water is incompatible to GC. After vacuum filtration‚ we can add ether and use rotarary evaporator to dry out the ether and then if the product is clean‚ it is ready of GC and further procedures. qDiscussion of Results Under normal conditions (low temperature/low acid concentration)
