Embodiment Construction

[0018] The present invention will be described in detail below in combination with specific embodiments.

[0019] A method for processing fresh jujube fruit powder. The selected jujube is washed with clear water to remove impurities and rotten fruit. The specific preparation steps are as follows:

[0020] 1. Separation of skin and flesh: use self-made special equipment to separate the skin and pulp of fresh jujube fruit;

[0021] 2. Separation of nuclear meat: separate the fresh jujube meat from the jujube core with self-made special equipment;

[0022] 3. Fine grinding: directly grind the fresh jujube meat after peeling and pitting into turbid juice, that is, jujube juice with jujube meat,

[0023] 4. Spray drying: The jujube juice with jujube meat that has been ground and has reached the standard fineness is spray-dried to become dry jujube powder; the sprayer used for spray drying is a centrifugal sprayer, and the main part is a high-speed rotating cutting machine. The di...

Abstract

The invention belongs to the technical field of fruit processing, and in particular relates to a method for processing fresh jujube fruit powder. In the prior art, the flavor and nutritional ingredients of the jujube powder are different from those of the fresh jujube. In order to overcome the problems of the prior art, the technical scheme adopted by the invention is as follows: the method for processing the fresh jujube fruit powder is characterized in that selected jujubes are cleaned by clean water, and impurities and bad fruits are removed. The method comprises the following specific steps: 1) separating skin from flesh; 2) separating kernels from flesh; 3) grinding accurately; 4) carrying out spray drying; 5) adding tapioca flour which accounts for 20% of the total weight of jujube powder, and mixing; and 6) packaging: packaging the dried jujube flesh powder to obtain jujube flesh powder products after drying fully. The method provided by the invention is perfect in process flow; and the prepared fruit powder is complete in nutrition and good in instant solubility, and has the faint scent and original taste of fresh jujubes.

Description

technical field [0001] The invention belongs to the technical field of fruit processing, and in particular relates to a processing method for fresh jujube fruit powder. Background technique [0002] Jujube is an ancient and traditional fruit in my country. It has a cultivation history of thousands of years. However, what people can eat now is the original product of jujube, the jujube juice extracted from dried jujube or the jujube powder product made from drying and grinding. The direct processing of jujube into jujube powder is still blank in the market. With the large-scale development of jujube cultivation in my country in recent years, the output of jujube has increased year by year and the people's higher demand for jujube products has begun to pay attention to the deep processing of jujube. In the market, many companies have produced a small amount of dried jujube through drying. Jujube powder produced by advanced technology, but its taste and nutritional components ar...
