Processing method of olive powder used in diversified ways

Abstract

The invention provides a processing method of olive powder used in diversified ways. The processing method of the olive powder used in the diversified ways specifically comprises the following steps:picking fresh olives free from shrinkage, browning, mechanical injuries, disease, insect pests, decay and spoilage, conducting draining after surfaces are rinsed with running water, then placing the drained olives in boiling water at 100 DEG C for blanching for 1 min, conducting nucleus-removing and crushing after cooling is conducted, spreading crushed flesh on a sample disk after nucleus-removing and crushing are conducted, placing the sample disk in freezing vacuum drying equipment for drying until a water content is 8% or below, then placing the dried flesh in an ultrafine grinder for grinding, and making obtained powder pass through an 80-mesh screen to produce a finished product of the olive powder subjected to freeze vacuum drying. According to the processing method of the olive powder used in the diversified ways, crushing and drying are conducted after the olives are subjected to blanching for color protection, thus the difficulty of pretreatment operation is reduced, a dryingeffect is good, raw material waste is avoided, the nutrition quality, bright green color and a strong olive flavor of the fruit powder are maintained, the fruit powder can be added into various kindsof food as a food base material, an accessory or the like, the technology is simple, a utilization rate of the raw material is high, and added value of the product and economic benefits are significantly increased.

Description

technical field [0001] The invention belongs to the technical field of deep processing of fruits and vegetables, in particular to a method for processing olive fruit powder. Background technique [0002] Olive fruit, also known as green fruit, green olive, sweet olive, etc., is rich in nutrition, unique in taste, astringent at first taste, sweet after chewing for a long time, rich in carbohydrates, amino acids, proteins, polyphenols, flavonoids and vitamins and other nutrients , and has a variety of health care medicinal effects such as protecting the liver, clearing heat and pharynx, antibacterial and anti-inflammatory, anti-tumor and anti-oxidation, and improving antibody immunity. It is the first batch of medicinal and edible species announced by the Ministry of Health of my country. Food dual-purpose value, can be eaten fresh and processed. However, olive processing and production are mostly concentrated in candied fruit, etc., and its pharmacological functions are greatl...

Problems solved by technology

At present, the drying methods of fruit powder are mainly spray drying, hot air drying, vacuum drying, etc. Spray drying is the most commonly used drying method in the continuous production of fruit powder, but it is not suitable for drying materials with high solid content. Processing method, raw material utilization rate is low, and fresh olive fruit has high cellulose content and is difficult to handle
