What is hurdle technology PPT?
Hurdle technology is the combined use of several shelf-preservation methods to make a product shelf-stable,to improve quality and to provide additional safety. Also known as “combined method technology”.
What is hurdle technology PDF?
technology.Hurdle technology is a new concept in the. preservation of foods of plant as well as animal origin. This technology is used in many countries of the world, including India. The factors used for food preservation.
What is meant by hurdle technology?
Hurdle technology is a concept that was developed to address the consumer demand for more natural and fresh foods. It is an intelligent combination of hurdles which secures the microbial safety and stability as well as retains the organoleptic, nutritional quality and economic viability of food products.
What are the factors include in hurdle technology?
Hurdle technology means combining various bacteria-inhibiting or bacteria-killing factors (some of the ‘hurdles,’ e.g., are salt, reduced pH, reduced water activity, heat treatment, and appropriative packaging) to achieve a safe product with acceptable shelf life and an acceptable taste and consistency.
How is Hurdle technology used in developing countries?
ABSTRACT Hurdle technology is used in industrialized as well as in developing countries for the gentle but effective preservation of foods. Previously hurdle technology, i.e., a combination of preservation methods, was used empirically without much knowledge of the governing principles.
Why do we use Hurdle technology in food preservation?
Microbial stability and safety, as well as the sensory and nutritional quality of most preserved foods, are based on a combination of several empirically applied preservative factors (hurdles), and more recently on knowingly employed hurdle technology.
When did Leistner invent the hurdle effect?
Leistner in 1976, introduced the term “hurdle effect”. NEED FOR HURDLE TECHNOLOGY Consumers are demanding for fresh, natural and minimally processed food products. Ongoing trend has been eat out and to consume ready to eat foods. 3. Preservative factors or hurdles disturb the homeostasis of microorganisms.
How does the sequence of hurdles ensure stability?
Sequence of hurdles ensures stability at eachstage. All hurdles decline with time except aw.Nitrite inhibits pathogensgrowth of other bacteria depletes oxygen acid-Low oxygen favours acid-producingcompetitive floraAcid decreases pHAw hurdle gradually increases due to drying. 18.
