Abstract

The invention discloses an orange residue sweet potato slice and a preparation method thereof. The orange residue sweet potato slice is prepared from orange residues and sweet potatoes. The method comprises the following steps: adding a defined amount of edible sugar and pectin solution into a pan, then adding orange residues and sweet potatoes and a defined amount of starch aqueous solution at a certain ratio, and heating and concentrating till becoming thick; pouring the concentrated thick pulp solution into a clean stainless steel disc; leveling, putting into an oven or a drying chamber for roasting till the product is not sticky, soft, dry and hard, and then peeling; and shaping and packaging, thereby obtaining the orange residue sweet potato slice. The orange residue sweet potato slice provided by the invention is unique in flavor and rich in nutrient, not only can effectively utilize orange fruit residues but also can increase the processing additional values of orange fruits, and can increase the resource utilization rate. Besides, the orange residue sweet potato slice is conveniently prepared, and the industrial production is easily realized.

Description

technical field [0001] The invention relates to a fruit cake, in particular to orange pomace sweet potato chips made of citrus fruit pomace and a preparation method thereof. Background technique [0002] Citrus is one of the dominant agricultural products in my country. At present, citrus pulp is an important raw material for light industry. It can be processed into canned food, candied fruit, jam, fruit cake, fruit peptone, fructose, and can also be made into beverages such as fruit juice and fruit wine. However, there is a large amount of orange pomace remaining, except for a small amount used as Chinese medicinal materials, candied fruit, pectin and orange oil, most of them are discarded, and the utilization rate is extremely low, which is a pity. The use of landfills to treat orange residue not only causes environmental pollution, but also wastes resources. Therefore, if these by-products are comprehensively utilized, it will not only greatly protect the environment, bu...
