Abstract

The invention discloses chocolate-flavor hazelnut kernels and a preparation method thereof. The method comprises the steps as follows: spreading, airing, packing and storing hazelnuts to prolong the storage life of the hazelnuts; then, selecting the hazelnuts, performing separation, shell breaking and shell-kernel separation; and performing selection, screening, low-temperature sectioned dewatering, air peeling, chocolate coating, cooling, polishing and packing on the hazelnut kernels. Low-temperature sectioned dewatering and air-process peeling are adopted for the prepared chocolate-flavor hazelnut kernels, the peeling rate of the hazelnuts is 99% or above, meanwhile, the integrity of the hazelnuts is high, pores are produced in the hazelnuts by the aid of pressure difference during preparation, chocolate is integrated with the hazelnut kernels more uniformly, nutrient ingredients in the hazelnuts can be effectively locked, the shelf life of the hazelnuts can be prolonged, secondary processing of the hazelnuts is broadened, and the health concept of modern people for nutrient complementation, comprehensiveness and balance is conformed.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing chocolate hazelnuts. Background technique [0002] Chocolate is one of the most popular foods in the world. It has a creamy, sweet and palatable taste. At the same time, it contains antioxidant substances, which are beneficial to human health when eaten in moderation. However, chocolate contains a lot of fat, and it is easy to eat a lot of pure chocolate. It can lead to obesity and related diseases. Therefore, there are chocolate products with nuts, such as hazelnuts, peanuts, etc. as auxiliary materials, or puffed food as the core in the market. However, puffed food often contains extra fat or additives, so it will reduce its nutritional value. [0003] Hazelnuts (hazelnuts) are known as "nuts" because they contain 20%~30% protein, 40%~50% fat, 13%~24% carbohydrates, 8.2%~9.6% dietary fiber and rich trace elements. In addition, hazelnuts also contain 8 kin...
