Study of the Efficiency of Trachyspermum ammi L. Essential Oil for its Application in Active Food Packaging Technology
The interest in essential oils and their application in food packaging and preservation has been amplified in recent years by an increasingly negative consumer perception of synthetic preservatives Close to one third of the world's food supply is wasted annually. As a major contributor, food spoilage represents an environmental problem as well as an ethical issue. Besides physical damage, browning and staling, molds and yeasts cause significant food waste. Protecting foods from spoilage is essential in order to reduce food waste and ensure safety for consumers. However the current methods employed for preservation carry serious drawbacks which have implications on the health and well being of the consumer. There is a strong need to replace synthetic methods with the use of botanicals. The food industries are developing new packaging systems (active packaging) through the incorporation of essential oils. Essential oils are naturally occurring, degradable, and cheaper than chemical preservatives. Ajwain is a commonly used spice and has been used as a traditional medicine in Indian culture. The current study identifies the fungi toxic potential of essential oil of Ajwain (T. ammi) against common food spoilage fungi and its application as a natural preservative and a prospective component of active packaging and micro atmosphere preservation systems. Using bread, a commodity commonly susceptible to fungal contamination in a modelling system aids in understanding the large scale and realistic application of the system developed. Further studies need to be carried out on the synergistic action of essential oil of T. ammi with other essential oils and other hurdle techniques. The organoleptic and sensory changes caused due to its strong aroma need to be tested further.
