Embodiment 1

[0018] Example 1: The mature goat's milk fruit (with a sugar content of 5%) is sorted according to the size of the head, washed with water to remove dirt and other dirt on the surface, soaked with 200ppm sodium hypochlorite at room temperature for 2 minutes, sterilized with a small amount of sterile water Rinse the goat's milk fruit and drain; use a peeler to gently remove the skin of the goat's milk fruit and remove the rotten and damaged parts. Use a tool to remove the goat's milk fruit core and cut the pulp into 3mm blocks. Use a double pass The beating machine beats the pulp into a pulp. During the pulping process, add D290 weakly basic anion exchange resin (Jiangsu Yunkai Resin Technology) and mix thoroughly with the pulp. The added amount is 5% of the pulp mass. Stir fully for 20 minutes. A 100-mesh screen removes the weakly basic anion exchange resin particles, clean the ion exchange resin and the screen with an appropriate amount of water, merge the washing water into th...

Embodiment 2

[0019] Example 2: The mature goat's milk fruit (with a sugar content of 5%) is sorted according to the size of the head, and the dirt and other dirt on the surface are washed with clean water, and sterilized by soaking in 300ppm sodium hypochlorite at room temperature for 1 min, and rinsing with sterile water Goat's milk fruit, drain; use a peeler to gently remove the skin of the goat's milk fruit, and remove the rot and damaged parts, remove the core of the goat's milk fruit with a tool, and cut the pulp into 5mm blocks, and use a double-pass beating The machine beats the goat's milk fruit pulp into a slurry. During the pulping process, add D290 weakly basic anion exchange resin (Jiangsu Yunkai Resin Technology) and mix it with the slurry. The added amount is 10% of the slurry mass, and the slurry is fully stirred for 30 minutes. , Use a 200-mesh screen to remove the weakly basic anion exchange resin particles, wash the ion exchange resin and screen with an appropriate amount o...

Embodiment 3

[0020] Example 3: The mature goat's milk fruit (with a sugar content of 5%) is sorted according to the size of the head, and the dirt and other dirt on the surface are washed with water, and sterilized by soaking in 250ppm sodium hypochlorite at room temperature for 1.5 minutes, using a small amount of aseptic Rinse the goat's milk fruit with water and drain; use a peeler to gently remove the skin of the goat's milk fruit and remove the rotten and damaged parts. Use a tool to remove the goat's milk fruit core and cut the pulp into 4mm blocks. Dao beater beats goat milk fruit pulp into pulp. During the pulping process, D290 weakly basic anion exchange resin (Jiangsu Yunkai Resin Technology) is added and the pulp is fully mixed. The added amount is 7% of the pulp mass. Stir for 25 minutes, remove weakly basic anion exchange resin particles with a 150-mesh screen, wash the ion exchange resin and screen with an appropriate amount of water, merge the washing water into the slurry, st...

Abstract

The invention discloses a deep processing method of Elaeagnus conferta fruits. The method comprises the following steps: sorting and washing of ripe Elaeagnus conferta fruits, soaking sterilization using sodium hypochlorite at room temperature, rinsing and draining; peeling and denucleation of the Elaeagnus conferta fruits, dicing, pulping, addition of ion exchange resin and sufficient stirring inthe pulping process, removal of the ion exchange resin by a screen, cleaning of the ion exchange resin and the screen with water, mixing water obtained after the cleaning with the obtained slurry, and sterilization; addition of lactobacillus to the sterilized slurry under aseptic conditions, fermentation, addition of white granulated sugar, beta-cyclodextrin and a spice to the obtained fermentedproduct after the fermentation is completed, uniform mixing, emulsification of the obtained mixed slurry, addition of the emulsified into a mold, freeze-drying for obtaining freeze-dried Elaeagnus conferta fruits, and packaging under aseptic conditions to obtain a finished product. The method solves the key problems of easy damage and heavy sour taste of fresh Elaeagnus conferta fruits, the prepared freeze-dried Elaeagnus conferta fruit tablet is convenient to transport, has moderate sweet and sour taste, can be conveniently eaten, and maintains the nutritional flavor and the pharmacodynamicactivity of the Elaeagnus conferta fruits, and the method can easily realize magnified production.

Description

Technical field [0001] The invention relates to a deep processing method of goat milk fruit. Background technique [0002] Goat milk fruit ( elaeagnus conferta ) Is an evergreen climbing plant of the genus Elaeagnus, which is distributed in southern Yunnan and southern Guangxi in my country. Goat's milk fruit is a delicious fruit with local characteristics. The ripening period is from February to April every year. After the fruit matures, the fruit changes from hard to soft, its astringency fades, the sweetness increases, the skin is thinner, and the flesh is tender and soft. Prone to mechanical damage. Goat's milk fruit is rich in nutrients, with a water content of up to 90%, and is rich in 8 essential amino acids. The total sugar content is 5.0-7.0%, of which reducing sugar accounts for more than 99%, and the total acid content can reach 8.0-8.0 on a dry basis. 10.0%, and mostly in the form of citric acid and malic acid, goat milk fruit also contains trace elements such as ca...
