Q. Which of the following factors affect/s the ease of cleaning of machine
- Material used for the machine fabrication
- Machine design
- Ease of dismantling
- All of the above
Answer: d)
- Desired results occur when optimal chemical reaction and mechanical action takes place. Agitation can help break up soils, increase wash efficiency and reduce wash time. Too much mechanical action can result in damaged surfaces, resulting in higher equipment and maintenance expenses. During the ware washing process, agitation typically occurs first with pre-scraping to remove stubborn food deposits. A specific amount of pressure is required to affect the response rate.
Q. Hot water should be used for cleaning equipment because
- It increase chemical activity of the detergent
- it melts fats
- it has sanitizing affect
- all of the above
Answer: d)
- When water heats up, its molecules move faster and bounce off each other more. As a result, hot water can dissolve much more material than cold water. This makes it the first choice for cleaning any kind of syrup, sugar, or salt crust.
Q. Modified atmospheric packaging (MAP) involves.
- Monitoring & adjusting of the gases
- introduction of a gas mixture other than air into a package
- introduction of a gas mixture same as the air into a package
- both a and b
Answer: b)
- According to the Food and Drug Administration (FDA), modified atmosphere packaging “involves either actively or passively controlling or modifying the atmosphere surrounding the product within a package made of various types and/or combinations of films.”
A modified atmosphere can be defined as one that is specially created by altering the natural distribution and makeup of atmospheric gases. When applied to packaging, this involves modifying or controlling the makeup of gases contained within each package to provide optimal conditions for increasing the shelf life and reducing oxidation and spoilage of perishable food and beverage products.
Q. EVOH stands for
- Ethylated vinyl alcohol
- Ethylene vinyl alcohol
- Ethyl vinyl alcohol
- Ethylidene vinyl alcohol
Answer: b)
- EVOH stands for Ethylene-vinyl alcohol copolymer and is a flexible, crystal clear, glossy thermoplastic copolymer.
Q. BOPP stands for
- Biaxially oriented polypropylene
- Biodegredable oxidized polypropylene
- Biodegredable & oriented polypropylene
- None of the above
Answer: a)
- BOPP is a popular label material made of plastic. It stands for Biaxially-Oriented (BO) Polypropylene (PP). Biaxially-oriented refers to the production process that stretches the film over two directions, making it stronger and more transparent. Polypropylene is a versatile polymer that’s used in labels, food packaging, clear bags, and many other things.
