ABSTRACT
In recent years, interdisciplinary research is more focused on particle size, which helps in exploring the relation between micro and macroscopic properties of various materials. Starch nanoparticles are generally synthesized by using acid/enzymatic hydrolysis, gamma irradiation, simple nanoprecipitation, ultra-sonication, and homogenization treatments. The properties like amylose content, pasting, rheological, morphological, size distribution, etc. are affected after the formation of nanoparticles from starch. This study emphasizes how various properties are changed in starch nanoparticles. Starch nanoparticles are mainly used in the formulation of nano-emulsion, nano starch-based composite film, and drug delivery. The impact on various native starch properties after the preparation of starch nanoparticles are less reported. So, all the aspects related to various starch properties and their nanoparticles are extensively reviewed in this study so that the listed findings can be utilized in future processes to increase the various foods and non-food utilization of starch nanoparticles.

The present study was initiated to experimentally optimize the conditions for extraction using Central Composite Design. The optimum temperature and time for the extraction of pectin from Jackfruit wastes using oxalic acid were found to be 90°C and 60min respectively. The yield of pectin under these optimum conditions was 38.42%. Extraction time and temperature showed a significant (p<0.05) effect on the pectin yield. This agreed well with the experimental result of 39.05±0.59g/g of pectin, under similar conditions. Experimental studies on a large scale using 10kg of jackfruit wastes, gave a yield of 38% pectin. Pectin isolated from Jackfruit wastes can be classified as low methoxyl pectin with promising applications in low sugar products.
