Problems solved by technology

[0005] However, the gold leaf tea leaves produced by this method have poor bonding effect between the gold leaf and the tea leaves and are easily separated, causing the gold leaf to exist alone without being attached to the tea leaves, and to make the tea leaves lose their original desired golden color

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] refer to figure 1 , figure 2 , a first preferred embodiment of the nano-gold food of the present invention, comprising a dry food unit 5 and a covering layer 6 formed on the surface of the food unit 5 .

[0032] The covering layer 6 includes a viscous food material 3 and a plurality of nano-gold gold foils 2 . In this first preferred embodiment, the food unit 5 is tea and the food material 3 is gum arabic, but the food material 3 can also be glutinous rice pulp, fructose, corn flour slurry, animal gelatin or vegetable gelatin, and any of them combination. The thickness of each piece of nano-gold gold foil 2 ranges from 35nm to 80nm.

[0033] refer to figure 2 , image 3 , a second preferred embodiment of the nano-gold food of the present invention, comprising a dry food unit 5 and a covering layer 6 formed on the surface of the food uni...

Abstract

A method for producing nanometer gold food and a finished product thereof. The production method in the invention comprises the following steps: preparing a plurality of sheets of nanometer gold foils with the thickness in the range of 35nm to 80nm, and then adding the abovementioned nanometer gold foils into a sticky food material and stirring evenly to form a viscous body. Afterwards, the viscous body forms a covering layer on the surface of a food unit in a spraying manner. At last, the food unit in the previous step is dried and nanometer gold food in a dry state is formed. Thus, the stickiness of the food material is used to achieve good effects in adhering the abovementioned nanometer gold foils and the food unit, and the nanometer gold food which has relatively high additional value and relatively good appearance is formed.

Description

technical field [0001] The invention relates to a nano-gold food, in particular to a manufacturing method and a finished product of the nano-gold food. Background technique [0002] High-purity gold is a legal food additive. Gold foil made of high-purity gold can lower brain pressure and calm the heart and liver. Therefore, it is also regarded as a blind medicine in Chinese medicine. There are already gold foil products on the market that commercialize gold foil, which not only makes the product have a special gold color but also is dazzling, and the gold foil used for food can be excreted from the body after dozens of hours, and will not accumulate in the body. Concerns about food safety. [0003] Traditional gold leaf is made by beating. In addition to the difficulty in the process, its thickness is prone to unevenness. The current nanotechnology can more easily produce nano-gold gold foil with a very uniform thickness. [0004] Taking Taiwan's invention patent certific...
