Synthesis and Food Applications of Resistant Starch-Based Nanoparticles

Starch is recognized biopolymer because it is abundant in nature. Dietary starches are major energy source for various human civilizations, and it is obvious that they may also contribute to health in very particular ways. Resistant starch has got a lot of interest because of its possible health advantages (similar to soluble fibre) as well as its functional qualities. Resistant starch improves blood cholesterol levels, microbial flora, gastrointestinal tract function, the glycemic index, and helps with diabetes management. Aside from the significant health advantages of starch, there is an additional benefit that it has a smaller effect on food sensory characteristics than usual sources of fibre, such as grains, bran, or fruits. Moreover, when boiled, many starches form weak-bodied and unpleasant gels, which are influenced negatively by temperature, humidity, and storage duration. The present review article highlights resistant starch as a functional food, starch extraction method, preparation of starch nanoparticles, and nano- and microencapsulation of probiotics in detail.
