Embodiment 1

[0025] A fermented fruit and vegetable product containing fructooligosaccharides and a preparation method thereof, comprising the steps of:

[0026] S1. Raw material pretreatment:

[0027] For fresh cabbage, pick out the leaves with impurities, insect eyes, and rot, and discard them. Cut one into four equal parts by weight for later use; add tap water to boil, let it cool for later use, and wait for pickled cabbage.

[0028] S2, making sauerkraut:

[0029] After cleaning the container, sterilize it with boiling water for 20 minutes; take 690.01g of cabbage pieces obtained in step S1 and place them in the container, mix 41.4g of salt, 13.8g of fructooligosaccharides and 1700ml of water and pour them into the container for placing cabbage at 15°C Put it in a water seal and ferment for 30 days to get sauerkraut.

[0030] The basic physicochemical properties, organic acids and electronic tongues of the sauerkraut prepared in this example were determined.

Embodiment 2

[0032] A fermented fruit and vegetable product containing inulin and a preparation method thereof, comprising the steps of:

[0033] S1. Raw material pretreatment:

[0034] For fresh cabbage, pick out the leaves with impurities, insect eyes, and rot, and discard them. Cut one into four parts for later use; add tap water to boil, and let it cool for later use.

[0035] S2, making sauerkraut:

[0036] After cleaning the container, sterilize it with boiling water for 20 minutes; take 690.16 g of cabbage pieces obtained in step S1 and put them in the container, mix 41.4 g of salt, 13.8 g of inulin and 1700 ml of water and pour them into the container where the cabbage is placed. Seal and leave to ferment for 30 days to get sauerkraut.

[0037] The basic physicochemical properties, organic acids and electronic tongues of the sauerkraut prepared in this example were determined.

Embodiment 3

[0039] A fermented fruit and vegetable product containing xylo-oligosaccharides and a preparation method thereof, comprising the steps of:

[0040] S1. Raw material pretreatment:

[0041] For fresh cabbage, pick out the leaves with impurities, insect eyes, and rot, and discard them. Cut one into four parts for later use; add tap water to boil, and let it cool for later use.

[0042] S2, making sauerkraut:

[0043] After the container was cleaned, it was sterilized with boiling water for 20 minutes; 690.29 g of cabbage pieces obtained in step S1 were placed in the container, and 41.4 g of salt, 13.8 g of xylooligosaccharide and 1700 ml of water were mixed and poured into the container for placing cabbage, 15 ℃ water seal and leave to ferment for 30 days to get sauerkraut.

[0044] The basic physicochemical properties, organic acids and electronic tongues of the sauerkraut prepared in this example were determined.

Abstract

The invention discloses a preparation method of fermented fruits and vegetables containing prebiotics. The preparation method comprises the following steps: boiling Chinese cabbages, and cooling; mixing table salt, prebiotics and water to prepare prebiotics pickling liquid; and mixing the prebiotic pickling liquid with Chinese cabbages, and fermenting at 14-16 DEG C for 28-32 days to obtain the pickled Chinese cabbages. Five prebiotics, namely fructo-oligosaccharide, inulin, xylooligosaccharide, galactooligosaccharide and stachyose, are added into a fruit and vegetable fermentation system, so that the physicochemical properties of fermented fruits and vegetables are improved, the content of organic acid is increased, the content of free amino acid is increased, the abundance of lactobacillus and Weissella is increased, and the flavor quality of the obtained fermented fruits and vegetables is greatly improved.

Description

technical field [0001] The invention relates to a preparation method of fermented fruits and vegetables containing prebiotics, belonging to the technical field of food. Background technique [0002] Fermented fruits and vegetables are a traditional popular food, mainly sauerkraut, kimchi and so on. Sauerkraut is a characteristic fermented food in Northeast China. The traditional pickling method of sauerkraut mainly uses cabbage as the main raw material, put it and salt into a fermentation tank, add water to submerge the cabbage, then seal it or press it with stones, and let it ferment for a month. At present, the commercially available sauerkraut products are of a single type, which has been unable to meet consumers' demands for product quality and health. Therefore, the sauerkraut product that develops new healthy nutrition has good market prospect. [0003] Prebiotics refer to some organic substances that are not digested and absorbed by the host but can selectively pro...
