RAW & PACKAGING MATERIALS & SHELF LIFE FOR FOOD PROCESS AND BEVERAGES

WHAT are RAW MATERIALS?

The staple may be a basic material from which goods, finish products or intermediate materials that also are raw materials are manufactured. On the other hand, the term raw material is used to denote materials that came from nature &is in an unprocessed or minimally processed state.

WHAT IS PACKAGING MATERIALS?

the packaging is often described as a coordinated system of preparing goods for transport, warehousing, sale & end-use.

Packaging &packaging labeling have several objectives-

1.physical protection.

2. Information transmission:(it provides how to use, transport, recycle or dispose of)

3.Marketing: Marketing communication & graphic design are applied to the surface of the package.

6.security: It reduces the security risk of shipment.

Shelf life study

What is the shelf life?

Shelf life is the length of your time that a commodity could also be stored without becoming unfit to be used or consumed. Again, the time period is that the recommended maximum time that products are often stored, during which the defined quality of a specified proportion of the products remains acceptable under the expected condition of distributed storage and display.

Purpose of shelf-life study

The purpose of doing the shelf life study is to determine the amount of time that the product can remain available to the consumer. This will determine what parameters of the products will be the first cause of potential hazards. A shelf-life study yields valuable data about the life expectancy of products

IS THERE ANY DIFFERENCE BETWEEN SHELF LIFE & EXPIRATION DATE?
