Example Embodiment

[0015] Example 1

[0016] 1 kg of camellia, after pulverization, add 10 kg of deionized hot water, after leaching for 1 hour, filter and separate the camellia extract with an 80-mesh sieve, and then filter it with a precision filter membrane, and intercept the finely filtered tea liquid with a fine ultrafiltration membrane A clear and transparent ultrafiltrate was obtained. Then, the ultrafiltrate is subjected to reverse osmosis concentration and vacuum concentration, and the obtained concentrated solution is spray-dried to obtain camellia functional instant tea powder. 0.1 g of the obtained camellia functional instant tea powder was put into two cups, and when 100 ml of 80° C. warm water and 20° C. water were added respectively, the camellia functional instant tea powder all dissolved immediately. The color, fragrance and taste of the tea soup are all good.

[0017] Example 2

[0018] 1 kg of camellia, after pulverization, add 10 kg of deionized hot water, after leaching for 1 hour, filter and separate the camellia extract with an 80-mesh sieve, and then filter it with a precision filter membrane, and intercept the finely filtered tea liquid with a fine ultrafiltration membrane A clear and transparent ultrafiltrate was obtained. Then, the ultrafiltrate is subjected to reverse osmosis concentration, and the obtained concentrated solution is spray-dried to obtain camellia functional instant tea powder. Put 0.1 g of the obtained Camellia functional instant tea powder into two cups, and when adding 100ml of 80°C warm water, the Camellia functional instant tea powder can be dissolved immediately, but the tea soup is slightly turbid, and the soup is yellowish brown and the aroma is poor; Adding water at 20°C will not dissolve completely. The analysis is all concentrated by reverse osmosis, and the time is too long, which will cause the...

[0019] Example 3

[0020] 1 kg of camellia, after pulverization, add 10 kg of deionized hot water, after leaching for 1 hour, filter and separate the camellia extract with an 80-mesh sieve, and then filter it with a precision filter membrane, and intercept the finely filtered tea liquid with a fine ultrafiltration membrane A clear and transparent ultrafiltrate was obtained. Then, vacuum-concentrate the ultrafiltrate, and spray-dry the obtained concentrate to obtain camellia functional instant tea powder. Put 0.1 g of the obtained Camellia functional instant tea powder into two cups, and add 100ml of 80°C warm water and 20°C water respectively, the Camellia functional instant tea powder will dissolve immediately, but the fragrance will deteriorate and the soup will turn brown deteriorating. Analysis vacuum concentration time is too long, the aroma is easy to oxidize.

Abstract

This invention belongs to the field of food technique, which relates to a functional instant tea flower powder and preparation thereof. This invention employs the tea flower as raw material and obtains the tea flower extracting solution by hot water infusion method; the tea flower extracting solution is manufactured to a tea flower concentrated solution by ultrafiltering, reverse osmosis concentrating, vacuum concentrating, sterilizing and aseptic packaging. The instant tea powder is produced by the method for spray drying or freeze drying. The functional instant tea flower powder prepared bythis invention is diffluent in cold water, the tea solution is transparent and the tea flavor is still primary taste. The tea flower powder not only is almost same as the tea infused directly by boiled water in smell, color and flavor, but also has high solubility and transparency. The processing of this invention has the advantages of high extracting efficiency, short extracting time and strong selectivity. The tea flower powder not only keeps the primary smell of tea flower and nutrition, but also has the effect of reducing blood sugar and triglyceride, is a new functional tea powder drink.

Description

technical field [0001] The invention belongs to the field of food technology, and relates to a camellia functional instant tea powder and a manufacturing method thereof. Background technique [0002] The research and development of instant beverages has a history of decades and is the product of the faster and faster pace of life. In recent years, it has been found that tea has various physiological activities, medical effects and health care value, which has been recognized by consumers. However, the soup color of existing tea products is seriously oxidized and browned, lacks clarification, mature taste, and poor aroma. In particular, the aroma of tea is seriously lost. In order to solve the problem of poor quality of instant tea, people have studied the method of adding various additives (such as excipients, essences, sodium bicarbonate) or changing process parameters in tea juice to produce Instant tea products, but the tea flavor is still poor. CN6116364.X discloses a...
