A savory or sweet snack having an expanded, crispy, chip-like textured, substantially uniform, homogeneous, cellular coating is obtained by tumbling an edible core material, such as nuts or dried fruit, and alternately applying an aqueous component and a preblended dry mixture on the tumbling edible core material to form a dough coating on the edible core material. The dough-coated core material may be heated by frying or baking to substantially reduce the moisture content of the dough, and to substantially expand the dough. The thick, expanded coating has a substantial amount of wheat yet it possesses a crispy, crunchy texture of a chip, rather than a leavened, mealy or flaky texture. Use of a pregelatinized waxy starch, which is not chemically modified, provides crispness and a high degree of expansion Use of a pure, raw potato starch which is not chemically modified promotes crunchiness and a chip-like texture and reduces oil pick-up or absorption during frying. The tumbling is preferably performed in a continuous belt coating device to achieve high production rates and uniform coating of individual core material pieces without agglomeration or sticking of pieces to each other.

A preparation method of straight chain dextrin embedded conjugated linoleic acid microcapsules comprises the following steps: dissolving waxy starch in water, heating for gelatinizing, cooling, adding isoamylase for complete debranching, centrifuging, and freeze-drying to obtain straight chain dextrin powder; and dissolving the straight chain dextrin powder, placing the obtained straight chain dextrin solution at a crystallization temperature, dissolving conjugated linoleic acid (CLA) in a preheated anhydrous ethanol solution, adding the obtained CLA solution into the solution, carrying out heat insulation stirring for a certain time, taking out, cooling to room temperature, centrifuging, washing the obtained precipitate by using an anhydrous ethanol/water mixed solution to remove uncompounded CLA, centrifuging, and carrying out vacuum drying on the finally obtained precipitate to obtain a microcapsule embedding material containing the CLA. The method improves the solubility of the straight chain dextrin and CLA compound, the oxidation stability of the CLA and the bioavailability in an aqueous solution, so the problems of low dissolvability of the straight chain starch compound, and easy automatic oxidation and low bioavailability of the CLA are solved, and the microcapsules can be added to functional nutrition reinforcement foods and staple foods as a nutrition reinforcement agent.
