Method and device for preparation of alimentary soft granular caviar

Abstract

A method and an apparatus for preparing an alimentary granular soft caviar similar to black (granular) caviar. The method involves the preparation of a mixture containing an albuminous colloid, water, and alimentary gelatin to form the grains, exposing the grains to tea water, dye-stuff, salt solution and gustatory components. The grains of caviar are obtained by supplying the mixture under pressure through gauged channels to a cavity with heated vegetable oil in its upper section, separating and washing the grains, tanning the grains in a tea extract, water washing, washing with salt solution, introducing to the product of a gustatory component in an amount not less than 10% of the total weight of the product and mixing the grains with vegetable oil. The albuminous colloidal solution is soy milk, foremilk of mammals, or a mixture of these components, a mixture of cow/soy milk, or whey of soy or cow milk. The grains are dyed by immersion in an extract from the rind of green walnuts. The apparatus includes a cavity containing the initial mixture, outlet pipes with stream-forming heads, a source of gas pressure, a cylindrical granulating cavity for forming grains of the product, a nipple for draining excess forming liquid, water jackets around the cavity and the granulating cavity, and a receptacle at the bottom of the granulating cavity for accumulation of the produced grains. The apparatus also contains a compressor supplying impulse gas into the granulating cavity through pipes located at the top of the granulating cavity oriented horizontally to the center of the granulating cavity. The top of the granulating cavity is wider than the body of the granulating cavity, in the shape of a funnel, and is enclosed by a heating unit, connected to a controller. The invention can be used on dairy kitchens and other small-sized alimentary firms to obtain small volumes of caviar, and also at dairy plants for preparation of large amounts of the dietary product.
