Embodiment 1
[0024] Embodiment 1: A kind of method for preparing tea soft capsules with Anji white tea and tea seeds as raw materials, adopts the following process steps: winnowing to remove dust and sand, and manually picking out mildew, insect damage, turning green Anji white tea and tea seeds; Drinking water is subjected to reverse osmosis to obtain purified water, and purified water, glycerin, and gelatin are added to the interlayer tank at a ratio of 1.2:0.35:1, and 0.3 times of sorbitol (plasticizer) is added to stir, and the steam interlayer is heated. After it melts, it is kept warm After standing still for 1.5 hours, turn on the vacuum pump and carry out vacuum degassing to obtain capsule liquid; select 3000 grams of high-quality tea seeds, extract tea seed oil by pressing, and then obtain 279 grams of refined oil through refining; select 100 grams of high-quality Anji white tea, wash Dry, crush, and pass through a 60-mesh sieve; take the sieved Anji white tea, wrap it with four la...

The invention relates to a method for preparing tea leaf soft capsules by taking Anji white tea and tea seeds as raw materials, and belongs to the technical field of tea product processing. The method comprises the following steps: selecting materials, melting a gel, extracting tea leaf seed oil, pre-treating the Anji white tea, extracting water-soluble nutrients, extracting oil-soluble nutrients, pressing and pelleting to obtain the finished product. A water extraction mode and an oil extraction mode are adopted in the whole extraction process respectively, and the water-soluble and oil-soluble nutrition factors are adequately utilized, however, because a water-soluble extract and an oil-soluble extract are difficult to wrap in the capsules simultaneously in a certain proportion, the water-soluble extract is subjected to spray-drying to prepare a powder to be doped into the capsules. According to the method disclosed by the invention, the tea leaf seed oil is further extracted as leaching solution by taking the by-product of the Anji white tea, that is, tea leaf seeds, as raw materials, and the capsules have more comprehensive nutrition factors compared with other capsules. The finally obtained product is full and stable, and has antioxidant and whitening effects to a certain extent; the product is suitable for being used by office workers due to the characteristic of being capable of being ready to eat.
Description
technical field [0001] The invention relates to a method for preparing tea soft capsules by using Anji white tea and tea seeds as raw materials, and belongs to the technical field of tea product processing. Background technique [0002] Tea leaves are rich in vitamin C, vitamin E and tea polyphenols with strong antioxidant activity. Compared with ordinary tea, Anji white tea has the advantage that it contains the least free radicals among the teas found so far, and Its amino acid content is 1-1.5 times higher than other tea varieties, up to 9%, while normal tea only contains 2-3%; its tea polyphenol content is also as high as about 10%. Tea seeds are rich in tea saponin, flavonoids, tannins, tea polyphenols and other ingredients, which have certain antioxidant activity; at the same time, tea seeds are rich in fatty acids, especially unsaturated fatty acids, which are also very beneficial to the human body. In addition, the oil extracted from tea seeds, a by-product of tea, ...
