Abstract. This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page. Hurdle technology was developed several years ago as a new concept for the production of safe, stable, nutritious, tasty and economical foods.
Hurdle Technology is a technology by which a preservation parameter can be used at an optimum level in order to get a maximum lethality against micro-organisms by a combination of two or more such parameters so that the damage to the sensory parameters of the food is kept to the minimum. Conventional preservation technologies such as thermal processing ensure the safety and shelf life of fruit-derived products but can result in the loss of physicochemical and nutritional quality attributes. This review examines innovative hurdle techniques to obtain novel fruit products with fresh-like characteristics. The multifactorial

Several novel But now, with a better understanding of preservation principles, i.e., aw,pH, Eh, temperature etc, and improved monitoring devices, the international use of this concept, i.e., “Hurdle Technology” is increasing. This hurdle effect is of fundamental importance for the preservation of foods, since the hurdles in stable products control microbial spoilage, food poisoning and the fermentation
Hurdle technology (also known as combination techniques or barrier technology) is a valuable tool in the fight against over-processing. It combines different preservation factors or techniques to achieve mild but reliable preservation. Why measure water activity? Water activity is the best index for microbial growth. A product may contain a relatively large percentage of moisture, but if the water is chemically “bound” to humectants or solutes, such as salts, sugars, or polyols, the water is biologically unavailable for microbial growth.

The microorganisms present in a food should not be able to overcome (ie, leap over) the hurdles inherent in this food. This is illustrated by the so-called hurdle effect (1), which is of fundamental importance for the preservation of intermediate-moisture foods (2) and high-moisture foods (3), since the hurdles in a stable product control Hurdle technology is the combination of different preservation techniques as a preservation strategy. There are more than 60 potential hurdles for foods that improve the stability and/or quality of minimally processed products.

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. But now, with a better understanding of preservation principles, i.e., aw,pH, Eh, temperature etc, and improved monitoring devices, the international use of this concept, i.e., “Hurdle Technology” is increasing. This hurdle effect is of fundamental importance for the preservation of foods, since the hurdles in stable products control microbial spoilage, food poisoning and the fermentation
Hurdle technology was developed several years ago as a new concept for the production of safe, stable, nutritious, tasty and economical foods. Conventional preservation technologies such as thermal processing ensure the safety and shelf life of fruit-derived products but can result in the loss of physicochemical and nutritional quality attributes. This review examines innovative hurdle techniques to obtain novel fruit products with fresh-like characteristics. The multifactorial
