This invention provides an application of vegetable micro-particle food product, which is made with starch-containing plant parts. With the original content of food product as the basis, the food product has at least one component, which can be removed through the water and whose content is reduced by 20-90 wt% relative to the natural plant part, preferably by 30-70 wt%, and more preferably by 35-65 wt%, wherein the at least one component that is depleted in content and capable of being removed through water is selected from starch of edible products rich in fiber, and/or protein and amino acid, and/or removable food fiber. The edible products rich in fiber are selected from gluten-free flour substitute with higher fiber proportion； dietary fiber-rich thickening agent； coating substance for food/pharmaceuticals； dietary- therapy food ingredients with higher fiber proportion； fiber-rich binding agent, edible film； and elastic and thermoplastic food products. Further, the starch-containing plant part is selected form root crops and tuber crops； beans and their fruits； tree fruits； shrub and shrub fruits； gramineous plants and fruits, and algae as well as algae species produced by the GMO method or cultivation including Tilling method. The amylose/amylopectin starch content of these species and/or protein and amino acid are greatly varied.一種植物性微粒狀食物產品的應用，該等食物產品係用含澱粉的植物部分製造，以該食物產品之原始含量為準，該食物產品之至少一可透過水移除之組分的含量比該天然之植物部分減少了20-90wt%，較佳30-70wt%，尤佳35-65wt%；其中該至少一經削減的、可透過水移除之組分係選自富含纖維之可食用產品中的澱粉，以及/或者蛋白質及氨基酸，以及/或者可除去的食物用纖維，該等富含纖維之可食用產品係選自：具較高纖維比例的無麩質的粉替代物；富含膳食纖維的增稠劑；用於食品/藥物的塗層物；具較高纖維比例的食療食物的組分；富含纖維的黏著劑，可食用的薄膜；具彈性及熱塑性的食物產品；其中，該等含澱粉的植物部分可選自：塊根作物及塊莖作物；豆類及其果實；樹果；灌木及灌木果實；禾本科植物及其果實，以及藻類及透過GMO法或包括Tilling在內的培育法製造出的藻類品種，該等品種的直鏈澱粉/支鏈澱粉含量，以及/或者蛋白質及氨基酸大幅改變。
