Embodiment Construction

[0021] 1. Preparation of freshly squeezed chestnut drink

[0022] 1) Pre-cooking and color protection: put the fresh chestnut kernels that have been peeled off in the color protection solution and soak at 60-75 ° C for 2-4 minutes; the color protection solution is ascorbic acid, phytic acid, citric acid and EDTA- 2Na mixed solution; the mass concentration of ascorbic acid in the color protection solution is 0.1-0.7%, the mass concentration of phytic acid is 0.1-0.4%, the mass concentration of citric acid is 0.1-0.7%, and the mass concentration of EDTA-2Na is 0.01- 0.02%;

[0023] 2) Rinse: Take out the chestnut kernels treated in step 1), rinse 3 times with distilled water and dry in an oven at 40°C for 30 minutes;

[0024] 3) Sterilization: From the chestnut kernels treated in step 2), select chestnut kernels with a golden color and smooth surface without brown spots and color protection solution, mix them with a material-to-liquid ratio of 8-10g:1mL, and put them into a hig...

Abstract

The invention discloses a preparation method of a freshly squeezed Chinese chestnut drink. The method comprises the steps of removing shells and coats of fresh Chinese chestnuts, and then pre-cooking the fresh chestnut kernels in color-protecting liquid for protecting the color; rinsing the chestnut kernels by distilled water, and drying; after that, selecting the golden chestnut kernels which are smooth in surface and free from brown spots, mixing the selected chestnut kernels with the color-protecting liquid according to the feed liquid ratio of (8g-10g): 1mL, putting the mixture into a high-temperature retort pouch, and carrying out autoclaved sterilization; taking out the sterilized chestnut kernels, mixing 30-40 parts by weight of chestnut kernels and 150-200 parts by weight of water, and pulping to obtain Chinese chestnut primary pulp; then, adding cane sugar, sodium alginate, carrageenan, carboxymethyl cellulose sodium, xanthan gum and monostearin into the obtained Chinese chestnut primary pulp; and evenly mixing, and carrying out vacuum packaging to obtain the freshly squeezed Chinese chestnut drink. According to the preparation method, hydrophilic colloid and an emulsifying agent can be reasonably blended, so that the probability of starch retrogradation of the freshly squeezed Chinese chestnut drink is effectively reduced, and the freshly squeezed Chinese chestnut drink has good suspension stability and is free of stratification within a longer time.

Description

1. Technical field [0001] The invention relates to a preparation method of a drink, in particular to a preparation method of a freshly squeezed chestnut drink. 2. Background technology [0002] Chestnut belongs to Fagaceae Chestnut nut plant, is my country's traditional agricultural and sideline products, one of the important dry fruits in the world, and chestnut is the main part that people eat. Chestnut is a kind of high-quality, cheap and nutritious tonic. It is known as the king of dried fruits and bread on trees. Because the calories contained in its fruit are similar to staple foods such as flour and rice, it can replace food, and it is also called woody. food. The water content of fresh chestnut is 50-80%, the starch content in the dry matter accounts for about 50-65%, the sugar content is 20-25%, the protein is 7-9%, and the total amino acid in the protein is 7.07%, which contains a variety of essential amino acids, respectively Lysine 0.37%, Methionine 0.1%, Threo...
