Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. The Artocarpus heterophyllus is believed indigenous to the Western Ghats of India. It is adapted only to the humid tropical and near tropical climate. The tree flourishes in rich deep soil of medium or open texture, sometimes on deep gravelly or laterite soil.
In India they say that the tree grows tall and thin on sand, short thick on sandy land. Here the physical and chemical properties of soil from surrounding plots of different varieties of Arthocarpus heterophyllus have been analysed by using different technical methods and evaluating the effects of soil property on jackfruit nutritional quality. It was observed that there was a considerable difference in case of some minerals likes phosphorous, potassium, magnesium, zinc and manganese. Change in the soil pH also noticed. The pH also plays a major role in the sweetness of the jackfruit. The optimum pH of the amylase inside the jackfruit was found to be 6.2 to 6.8.
The result shows that the soils that have higher pH have more sweet flakes. Proximate nutritional composition of the flake reveals the presence of protein, fat and fibre in a greater amount in some flake and these flakes were sweeter than the others. There was a much difference in the sugar level also. Increased protein, fat and fibre content found in flake of the trees that were growing in soil that have higher concentration of minerals. Further studies such as molecular studies, enzymatic studies should conduct to identify the whole variation among jackfruit in Kerala. Encouragements should be done to the marketing as well as value added food products from this underutilized fruit tree.

Chapter Summaries
Chapter 2 Effect of soil properties on the nutritional quality of jackfruit (Artocarpus heterophyllus) varieties in Southern parts of Kerala: This chapter delves into the impact of various soil properties on the nutritional content of jackfruit in Southern Kerala. It begins with an introduction outlining the taxonomic classification of jackfruit and a review of existing literature on the topic. The research methodology meticulously details the sampling procedures, and the methods employed to determine organic carbon, available phosphorus, potassium, magnesium, calcium, zinc, copper, manganese, electrical conductance, pH, and bulk density of the soil samples. Furthermore, the methods for analyzing the proximate nutritional composition of the jackfruit, including starch and reducing sugars are described. The results and discussion section analyzes the correlation between soil properties and the nutritional profile of different jackfruit varieties, offering a comprehensive understanding of the interplay between soil conditions and fruit quality. Statistical analysis is used to draw meaningful conclusions about the significant relationships identified. The chapter concludes with a summary of the key findings.
Chapter 3 Analysis of factors affecting the sweetness among jackfruit (Artocarpus heterophyllus) varieties in Kerala: a brief overview: This chapter focuses on the factors influencing the sweetness of jackfruit varieties in Kerala. It starts with an introduction, covering the taxonomic classification of jackfruit and a review of relevant literature. The methodology encompasses the selection of study areas, data and sample collection, the preparation of crude enzyme extracts, soil analysis, and the determination of reducing sugar and starch concentrations before and after fruit ripening. The analysis also includes the determination of amylase activity under different conditions (pH and temperature) and proximate analysis. The results and discussion section elaborates on the findings concerning the impact of various factors on the sweetness of jackfruit, including moisture, protein, fat, ash, and fiber content, providing a detailed analysis supported by statistical methods. The chapter concludes by summarizing the key findings regarding the factors that significantly influence the sweetness profile of the different jackfruit varieties.
