Problems solved by technology

However, most of the existing jujube juice processing uses dried dates as raw materials, and almost no fresh jujube juice products are processed and produced with fresh dates as raw materials; most of its existing jujube juices use pre-heating treatment (such as patent ZL200410023975.2), and use high temperature Sterilization (such as patents ZL201210167188.X, ZL201010033320.9, ZL200410024274.0, ZL200410023975.2, etc.), the obtained product is brown, compared with fresh jujube, it loses most of the heat-sensitive nutrients, and its flavor is burnt Fragrance, no smell of fresh jujube fragrance; steps such as crushing, extraction (such as ZL02100872.8), enzymatic hydrolysis (such as patent ZL201010033320.9) also have a great influence on the flavor of jujube juice; and the existing jujube juice beverage also has Formulated with food additives, the juice content is not high

Abstract

The invention discloses non-concentrated freshly squeezed compound fresh jujube juice and a processing method thereof, and the compound fresh jujube juice comprises the following raw materials by weight: 45-60 parts of fresh jujube, 45-60 parts of snow pear, 7-10 parts of kiwi fruit and 1-5 parts of cucumber. The compound fresh jujube juice is prepared as follows: a variety of finely selected ripe fresh fruits are pretreated and then frozen for more than 24h, then pulped and squeezed at 0 DEG C, and then processed by vacuum degassing, aseptic filling, and ultra high pressure sterilization. The compound fresh jujube juice prepared under the cold processing conditions is not subjected to heat treatment to prevent damage of nutrient substances in fruit and fresh jujube color degradation, the prepared compound fresh jujube juice product is green and yellow in color, uniform in quality, refreshing and fragrant, and is non-concentrated freshly squeezed nutritional fresh jujube juice meeting modern consumption demands.

Description

technical field [0001] The invention belongs to the technical field of jujube processing, and relates to a non-concentrated freshly squeezed compound fresh jujube juice and a processing method thereof. Background technique [0002] Fresh dates are rich in a variety of nutrients and functional ingredients, and have many health effects such as strengthening the spleen and stomach, nourishing the middle and nourishing qi, nourishing the lungs and strengthening the kidneys, relieving drug poisoning, and anti-aging. It is one of the traditional fruits loved by the Chinese people . Fresh dates are rich in nutrients, among which, V C The content is 70 times that of apples and 140 times that of pears. However, most of the existing jujube juice processing uses dried dates as raw materials, and almost no fresh jujube juice products are processed and produced with fresh dates as raw materials; most of its existing jujube juices use pre-heating treatment (such as patent ZL200410023975...
