Abstract

Tender jack is generally consumed as a vegetable and it is characterized by its meat-like texture hence it is called as vegetarian meat, availability of tender jack in the market throughout the year is a critical aspect related to its trade. However, several factors limit its year around availability which include seasonal nature, geographically limited growth due to climatic variations, high perishability and difficulties related to storage and transportation due to limited technologies, as jackfruit is seasonal fruit dehydration is one of the best and suitable method for storage of tender jack during offseason. Tender jack is more prone to browning hence, pre-treating fruits for storage is an important step in preserving the produce. Taking this into consideration, standardization of pre-treatment for dehydration of tender jack was studied. The experiment was laid out in Completely Randomized Design (CRD) with seven treatment and three replications. The various pretreatments such as Potassium Metabisulphite (KMS), Citric Acid (CA) and Potassium Sorbate (PS) were used at different concentrations. Among different pretreatments, KMS 0.3 per cent showed the maximum carbohydrates (13.18 %), crude fiber (3.28 %), protein (2.26 %), starch (1.36 %) sensory color score (4.97) and low phenol (32.07 mg GAE/g).

Tender jack, potassium metabisulphite, dehydration, pretreatment

Conclusion

Among all the pretreatments KMS 0.3 per cent showed the maximum carbohydrates, crude fiber, protein, starch, sensory color score and low phenol followed by KMS 0.2 per cent. Based on the findings about the biochemical and sensory characteristics (colour score) of fruits, it was determined that tender jack dehydration could be successfully accomplished by pre-treating the fruits with 0.3 per cent KMS.
