Let us define
Brine solution - a solution of salt and water.
Brochure - a pamphlet
Catalogue - a systematic arrangement of listed items giving descriptive details.
PPT - parts per thousands
Standard - an authorized unit of weight or measure.
Procedure in Using Standard Measuring Devices and Instruments Below are some procedure in using standard measuring devices and instruments:
1. Salinometer
a. Prepare brine solution.
b. Pour brine solution in a cylinder.
c. Dip salinometer in brine solution.
2. Thermometer
a. Dip thermometer in boiling liquids.
b. Record the reading by OC or OF c. Clean after cleaning.
3. Refractometer
a. Place a drop of fresh sap or syrup sample on the refractometer.
b. Close the cover.
c. Quickly read the scale (the line on the top of the darker area). Readings should be taken to the nearest 0.1 percent.
d. Dry with tissue paper and rinse with water after each reading.
4. Glass-wares like cylinder, beaker, flask
a. Pour liquid ingredients into the cylinder, beaker or flask.
b. Bring the cylinder to eye level.
c. Get the reading at the lower meniscus.
d. Record the reading.
e. Clean after using.
It is important to review all procedure regarding the use of all standard measuring devices to ensure that they will be properly use in accordance with manufacturer’s specification.
Being familiar with the procedure on using a standard measuring device like a salinometer, thermometer, weighing scale or a measuring cup or spoon will enable a food processor to use the appropriate measuring device as called for in a food processing activity. It also enables him to work systematically and accurately.
LET US REMEMBER
Follow the required procedure in using the standard measuring devices and instruments according to manufacturer’s specification in order to accurately use them and obtain desired results.
Valuing
Always practice accuracy in using measuring devices and instruments when measuring ingredients.
