Problems solved by technology

Also have the processing of some low-sugar preserved fruit to just reduce the sugar content of product, do not add other filling agent and sweetener additionally, product final sugar content 40-60% does not wait (as CN1065385; CN1775060; CN1899073; CN1969649 etc. )
But there is no report on the development of low-sugar and low-calorie candied jujube in many methods for preparing preserved fruit

Embodiment 1

[0030] 1. Raw material pretreatment: Take 500g of fresh jujube fruit, wash the jujube fruit with clean water, drain the water, and then use a wire scribing machine to scribble, the scribing depth is about 1.5-2.0mm, the texture is even, and each jujube fruit is slitting 60 lanes.

[0031] 2. Blanching: Put the shredded jujube fruit into boiling water at 100°C for 1 minute, remove and drain.

[0032] 3. Candied and dipped: Heat 800ml of erythritol solution with a mass fraction of 35% to 90°C, add the blanched jujube fruit, then cook at this temperature for 50 minutes, remove and drain the erythritol Alcohol sugar solution, then put jujube fruit into 800ml pre-heated to boiling, immerse in 55% sucrose solution for 24 hours, pull out and drain the sugar solution.

[0033] 4. Baking: Take out the dipped jujube fruit and drain the sugar liquid, spread it on a baking tray, put it in a blast oven, and gradually raise the temperature to 70°C. During the baking process, the temperatur...

[0035] 1. Raw material pretreatment: Take 500g of fresh jujube fruit, wash the jujube fruit with clean water, drain the water, and then use a wire scribing machine to scribble, the scribing depth is about 1.5-2.0mm, the texture is even, and each jujube fruit is slitting 60 lanes.

[0036] 2. Blanching: Put the shredded jujube fruit into boiling water at 100°C for 0.5 minutes, remove and drain.

[0037] 3. Sugar cooking and dipping: heat the mixed solution of erythritol with a mass fraction of 25% and sucrose with a mass fraction of 25% to 100°C, add the blanched jujube fruit (the volume of the sugar solution is based on the submerged jujube fruit) , boiled at this temperature for 40 minutes, then the above-mentioned mixed sugar solution and jujube fruit were transferred to the soaking container, soaked at room temperature for 20 hours, pulled out and drained the sugar solution.

[0038] 4. Baking: Take out the soaked jujubes and drain the sugar liquid, spread them on a baking...

Embodiment 3

[0040] 1. Raw material pretreatment: Take 500g of fresh jujube fruit, wash the jujube fruit with clean water, drain the water, and then use a wire scribing machine to scribble, the scribing depth is about 1.5-2.0mm, the texture is even, and each jujube fruit is slitting 60 lanes.

[0041] 2. Blanching: Put the shredded jujube fruit into boiling water at 100°C for 1 minute, remove and drain.

[0042] 3. Candied and soaked: adding the erythritol solution of 30% erythritol solution into the vacuum pot after the blanched jujube fruit and the mass fraction (the volume of the erythritol solution is based on the submerged jujube fruit), vacuumize to - 0.08Mpa, heated to 60°C, boiled at this temperature for 40 minutes, fished out and drained the erythritol sugar solution, and then put the jujube fruit into the sucrose solution heated to boiling in advance and with a mass fraction of 50% for 24 minutes. Hours, remove and drain the sugar solution.

[0043] 4. Baking: Take out the dipp...

Abstract

The invention relates to a manufacturing method for golden thread preserved dates with low carbohydrate and lower calorific value, which comprises the steps of the screening, the cleaning, the filum dividing, the scalding and bleaching, the saccharifying and soakage, the baking and the reshaping of Chinese date fruit and the packaging of finished products; and is characterized in that: ethroglucin is used for replacing part of saccharose in the saccharifying or soakage process for manufacturing the Chinese date fruit. Being determined by tests, the sugar content of the golden thread preserveddates produced by the method of the invention is reduced from 70 percent or so which is originally processed by adopting the traditional technology to 20 to 30 percent, and the original flavor and sweet taste of the golden thread preserved dates are not affected; furthermore, as the permeation pressure of the ethroglucin is high, sugar-permeating time is greatly reduced, process is simplified andcost is reduced; in addition, the ethroglucin does not have the Maillard reaction of reducing sugar, therefore, in the process of saccharigying, the color change of the Chinese dates is small, and the products have light color and luster and better condition.

Description

technical field [0001] The invention relates to a method for preparing candied golden dates, in particular to a method for preparing candied golden dates with low sugar and low calorific value, and belongs to the technical field of food processing. Background technique [0002] Since ancient times, people have regarded jujube as an important tonic and traditional Chinese medicine. Li Shizhen said in "Compendium of Materia Medica": Jujube is sweet in taste and warm in nature. A little, so jujube is also called "the introduction of a hundred medicines". There are also folk proverbs that "eat three jujubes every day, and you will never grow old in a lifetime", "five grains plus red dates are better than Ganoderma lucidum", which highly praise the food tonic and medicinal effects of jujube. Regular consumption of jujube helps to treat diseases such as weakness, neurasthenia, disharmony of spleen and stomach, indigestion, cough due to overwork, anemia and emaciation. Jujube fru...
