Packaged Product Quality and Shelf life
Definition
The right choice of packaging materials can have an impact on the product quality and shelf life of packaged meals. Products are adequately safeguarded while being transported and stored is known as
packaged product quality.
This covers every aspect, from the quality of the materials used to construct the packaging to the manner in which the item is packaged and delivered.
The term
"shelf life"
refers to the period of time during which you can anticipate a product to appear, behave, and be safe for use. The type of product, how it is used, and how it is stored all affect how long it lasts.
Shelf life of food
, which is determined by four primary aspects including formulation, processing, packing, and storage conditions, is the amount of time during which the food maintains an acceptable level of safety and organoleptic quality.
Factors affecting quality and shelf life
Intrinsic Factor (related to the product itself)
Water Activity
Moisture Content
pH
Salt content
Sugar Content
Nutrient Content
Oxidation Potential
Extrinsic factor(related to external conditions)
Time
Temperature
Packaging materials
When steaks are vacuum packed, for instance, oxygen is removed from the packaging.
Processing methods
Chemical preservatives
Hygiene
SHELF LIFE STUDIES
Retain the desired palatability and quality
Maintain the physical, chemical, and microbiological integrity of it.
Maintain health and adhere to dietary declarations
Types of shelf life
Direct or real-time study
Stored under normal conditions for a period of time greater than the estimated shelf life
Indirect or accelerated shelf life study
A food's shelf life is forecast utilising several parameters. The pace of food deterioration is accelerated by applying conditions to it, such as higher temperatures.
BENEFITS OF EXTENDING SHELF LIFE
A higher grade of product
Less food loss and waste
Better brand reputation
METHODS OF INCREASING SHELF LIFE
Preservatives can be added but there are also consumer friendly ingredients that can be used as alternative.
Citric Acid
Lemon Juice
Antioxidants, such as rosemary extract, vitamin C or vitamin E
Vinegar
