Problems solved by technology

However, as we all know, due to the high starch content of chestnuts, chestnut kernels are relatively easy to break during cooking, and the breakage rate after cooking and processing mature products is also high, which is not only inconvenient to eat, but also unfavorable for packaging and making instant food. Cook the chestnuts with additives such as edible gum, which will reduce the taste of the processed chestnuts

Embodiment 1

[0028] Cooked chestnut kernels are made from chestnut kernels, and the preparation method includes steps:

[0029] Preparation: Refrigerate fresh chestnuts at 1°C for 4 days, then cut a hole in the chestnut shell, bake the cut chestnuts, and use staged heating during the baking, first raise the temperature to 40°C, add chestnuts and bake Bake for 6 minutes, then raise the temperature to 70°C for 4 minutes and bake for 5 minutes, then raise the temperature to 150°C for 3 minutes, then shell the roasted chestnuts to obtain chestnut kernels, and then select plump chestnut kernels for cleaning, and then After cleaning, the chestnuts with water on the surface are quickly frozen and refrigerated at -12°C for 3 months for later use;

[0030] Sugar solution cooking: thaw the quick-frozen chestnuts naturally in a cool place, use water and honey to prepare a sugar solution with a sugar content of 32°Bx, add chestnuts at 88°C, heat and cook for 70 minutes, then stop heating, and cool dow...

Embodiment 2

[0034] Cooked chestnut kernels are made from chestnut kernels, and the preparation method includes steps:

[0035] Preparation: Refrigerate fresh chestnuts at 6°C for 2 days, then cut a hole in the chestnut shell, and bake the chestnuts after the cuts. During the baking, the temperature is raised in stages. First, the temperature is raised to 50°C, and the chestnuts are added to bake. Bake for 3 minutes, then raise the temperature to 90°C for 2 minutes in the next 7 minutes, then raise the temperature to 180°C for 1 minute in the next 5 minutes, then shell the roasted chestnuts to obtain chestnut kernels, and then select plump chestnut kernels for cleaning, and then After cleaning, the chestnuts with water on the surface are quickly frozen and refrigerated at -24°C for 6 months for later use;

Abstract

The invention discloses cooked sweet chestnut kernels and a preparation method thereof. The cooked sweet chestnut kernels are prepared from chestnut kernels through the following steps: preparing chestnut kernels, boiling the chestnut kernels with sugar liquid, and then performing air-curing, vacuum packaging and sterilization, wherein the boiling with the sugar liquid comprises the steps of adding the chestnut kernels into the sugar liquid with sugar degree of 32-37 Bx at a temperature of 88-92 DEG C, then performing heating and heat preservation for boiling for 50-70 minutes, then stopping heating, and naturally cooling for 7-9 hours. The cooked sweet chestnut kernels effectively reserve the complete shape of the chestnut kernels and the sweetness and waxiness of the chestnut kernels, have taste and agreeable sweetness, and reserve the flavor of the chestnut kernels.

Description

technical field [0001] The invention relates to a food processing technology, in particular to a cooked chestnut kernel and a preparation method thereof. Background technique [0002] Chestnut is rich in nutrients, the fruit contains 50-60% starch, 5.7-10.7% protein, 2-7.4% fat, and also contains monosaccharides and disaccharides, carotene, thiamine, riboflavin, niacin , ascorbic acid, calcium, phosphorus, iron, various vitamins and trace elements, especially the content of vitamin C, B1 and carotene are higher than that of ordinary dried fruits. Traditional Chinese medicine believes that chestnut has the functions of nourishing the kidney and spleen, strengthening the body, benefiting the stomach and calming the liver. and other effects, known as "the fruit of the kidney". Chestnuts are processed and eaten at present, and the chestnuts are shelled and processed into chestnut powder for consumption, or the shells are roasted, steamed and then shelled for consumption, which ...
