specific Embodiment approach 1

[0048] A kind of black water chestnut, the nutritional content of every 100g black water chestnut is: energy 452KJ, protein 2.2g, fat 0.4g, carbohydrate 23.5g, reducing sugar 12.3g as glucose, total sugar as sucrose 11.7g, total polyphenols 12.76mg, melanoidin 740mg.

[0049] For the black water chestnut described in this embodiment, the mineral content per 100g of black water chestnut is: sodium 15mg, iron 16.7mg, calcium 9mg, phosphorus 27mg.

[0050] For the black water chestnuts described in this embodiment, the other contents per 100g of black water chestnuts are: moisture 72.1g, ash content 1.8g.

[0051] Using the black water chestnut of this embodiment, the antioxidant effect of the black water chestnut on SPF grade KM mice was tested by investigating the blood indicators in the animal body. The experimental method is to select 30 KM mice with a body weight of 18g-22g. The experiment is divided into three groups randomly according to the body weight of the mice. Group...

specific Embodiment approach 2

[0056] According to the preparation method of the black water chestnut described in specific embodiment one, comprises the steps:

[0057] Step 1, raw material selection: select fresh water chestnuts without damage by diseases and insect pests as raw materials;

[0058] Step 2. Raw material cleaning: wash the water chestnuts selected in step 1 with clean water, and drain the water on the surface of the water chestnuts for later use;

[0059] Step 3, bagging and sealing: put the spare water chestnuts in step 2 into a high-temperature-resistant food-grade plastic bag, after sealing, put it in a closed fermentation container, and prepare for fermentation and aging;

[0060] Step 4. Fermentation and maturation: Set the fermentation temperature to carry out the variable temperature fermentation process. The variable temperature fermentation process is divided into 15 stages. The specific temperature parameters of each stage are as follows:

[0061] The first stage: the temperature...

Abstract

The invention discloses black water chestnuts and a preparation method thereof, and belongs to the technical field of food processing. The black water chestnuts prepared by the preparation method contain the following nutrients in per 100 grams: 445-455 kilojoules of energy, 2.0-2.4 grams of protein, 0.3-0.4 grams of fat, 21.3-24.7 grams of carbohydrates, 11.5-13.3 grams of reducing sugar (taken as glucose), 10.3-12.7 grams of total sugar (taken as sucrose), 11.65-13.76 milligrams of total polyphenols, 722-750 milligrams of melanoidin, 12-17 milligrams of sodium, 15.4-17.7 milligrams iron, 8-10 milligrams of calcium, 25-27 milligrams of phosphorus, 70.6-74.1 grams of water, and 1.6-2 grams of ash. No food additive is added during the processing process of the black water chestnuts; moreover, the prepared black water chestnuts are sour-sweet and delicious in taste, as well as pleasant in color and luster. The black water chestnuts are health-caring foods with multiple health-care functions, including anti-oxidation, anti-tumor, anti-bacterium functions and so on.

Description

technical field [0001] The invention belongs to the technical field of food processing; in particular, it relates to a black water chestnut and a preparation method thereof. Background technique [0002] Water chestnut, commonly known as horseshoe, also known as ground chestnut and black tea, is a medicinal and edible ingredient with the same origin. The meat is tender, juicy and sweet, crisp and refreshing. Water chestnuts contain water, carbohydrates, protein, fat, crude fiber, minerals and other nutrients.
