Problems solved by technology

Because Dendrobium contains a lot of crude fiber, the taste of fresh Dendrobium is relatively rough when eaten directly, and many residues will be left after eating. The soluble dietary fiber cannot be fully utilized. So far, there is no Dendrobium candied fruit that can be eaten directly and taste good.

Embodiment Construction

[0010] (1) Remove the leaves of the harvested fresh dendrobium, remove the parts bitten by mildew and insects, rub and wash with water, drain the water after washing, and cut into strips with a length of 2cm.

[0011] (2) Put the segmented dendrobium into the steam explosion container and pass in steam, set the steam pressure in the explosion container to 0.8-2.5MPa, control the temperature at 180-240°C, and hold the pressure time of the explosion container at 5-2. 8s.

[0012] (3) Open the blasting container to release the pressure so that the Dendrobium material is ejected, and the material is blasted into the receiving tank to cool for 15 minutes, and the material outlet valve of the receiving tank is opened to collect the Dendrobium material after steam explosion pretreatment.

[0013] (4) Mix the treated dendrobium material with honey with a water content of 20-25% in a weight ratio of 1:1, so that the honey evenly adheres to the surface of the dendrobium.

[0014] (5) P...

Abstract

The invention discloses a preparation method of noble dendrobium stem preserved fruits. According to the preparation method, the technologies of steam explosion, vacuum impregnation, aseptic packaging and the like are adopted, wherein the steam explosion is that part of fibers are degraded into soluble dietary fibers and hemicelluloses are converted into small-molecule oligosaccharide which can be easily absorbed by a human body, and the dissolution of the oligosaccharide can be used for increasing the sweetness of the product, saving the usage amount of sugar and reducing the cost for preparing the preserved fruits. The steam explosion ensures that the surface area of each cell structure of a noble dendrobium stem raw material is increased, the obtained product is soft in organization structure and loose in cell structure, the prepared preserved fruit is relatively soft in texture and relatively exquisite in mouthfeel, and the nutrient substances can be relatively easily digested and absorbed by human intestines and stomach. Because the vacuum impregnation is performed in a closed state, the impregnation time of the sugar is shortened, and the requirements of high efficiency and sanitation are met. Therefore, fresh noble dendrobium stems become a snack food which is convenient to carry, simple and convenient to eat, favorable to store and fresh and delicious in mouthfeel, is nutritional and can promote human healthy functions.

Description

technical field [0001] The invention relates to a method for making candied fruit, in particular to a method for making candied fruit by using fresh dendrobium nodulum, and belongs to the technical field of food processing. Background technique [0002] Dendrobium: Orchidaceae is a perennial herb, also known as: black knot grass, the stem is erect, cylindrical, 9-35 cm long, 2-4 mm thick, sepals and petals yellow-green, oblong-lanceolate, stem fiber There are more elements. Its stem is used as medicine and belongs to the yin-tonifying medicine in the tonic medicine, which is beneficial to the stomach and promotes body fluid, and has the functions of nourishing yin and clearing away heat. Dendrobium contains a large number of medicinal active ingredients that are beneficial to human health, has unique medicinal value, and has anti-tumor, anti-coagulation, lowering blood fat, lowering blood pressure, improving immunity, anti-aging and other effects. In recent years, it has b...
