Main Functions of Powder Black Tea

Powder Black Tea refers to the facility of catechins (flavanols), flavones and flavonols, anthocyanins, phenolic acids and depsiphenolic acid polyphenol compounds in tea. Except for phenolic acids, they all have a C6-C3-C6 fundamental carbon structure with 2-phenylchroman (flavan) as the main body. Among them, catechins are the major parts of tea polyphenols, making up regarding Tea polyphenols represent 50% to 70% of the complete quantity of tea, accounting for 12% to 24% of the completely dry weight of tea. It is a type of substance with a fairly intricate structure, consisting of catechin, gallocatechin, and gallocatechin gallate., catechin gallate, etc. The content of tea polyphenols in tea is typically more in green tea than in black tea, and much more in summertime and fall tea than in spring tea. The main medical impacts of tea polyphenols are:
( 1) Decrease blood lipids and prevent atherosclerosis. Several research studies have actually revealed that alcohol consumption tea can minimize blood cholesterol degrees and has obvious anti-atherosclerotic functions. This is due to the fact that tea polyphenols play an important duty in the body’s fat metabolic rate, prevent the surge in cholesterol levels in plasma and liver, and advertise the discharging of lipid compounds from the feces. Consequently, it can not only stop and treat arteries Atherosclerosis, and additionally has the effect of reducing weight.
( 2) Enhance capillaries and reduced blood sugar level. Tea polyphenols can not only prevent the rise in capillary permeability caused by excess fat, but likewise collaborate with tea alkaloids to relax the blood vessel wall and boost the efficient size, which is beneficial to the leisure of human blood vessels and enhances the strength of the capillary wall surface. Plays a duty in preventing capillary rupture. Experiments reveal that catechins can additionally properly reduced blood sugar level and decrease the threat of diabetes mellitus.
( 3) Anti-radiation. Regarding the radiation defense of tea, it was first reported by Japan. They located that amongst survivors of the atomic battles, those who consumed tea routinely had less serious radiation health issues. A collection of pet examinations have actually revealed that tea polyphenols have obvious anti-radiation impacts. It is usually believed that the anti-radiation result of tea polyphenols is related to its participation in redox responses in the body, safeguarding blood stage, fixing physical features, and hindering interior blood loss. On top of that, tea polyphenols can lower DNA damages caused by radiation.
( 4) Anti-aging. Peroxidation of lipids in the body is among the devices of human aging, and totally free radicals are the main factor in peroxidation in the organism. Tea polyphenols have a strong totally free radical scavenging effect, which can play an antioxidant and anti-aging result. Animal experiments show that Powder Black Tea can prevent lipoxygenase activity and lipid peroxidation in skin mitochondria.
( 5) Anti-cancer and anti-mutation. Free radicals might play a specific duty in the process of carcinogenesis, so the cost-free radical scavenging result of tea polyphenols can play an anti-cancer role. Green tea and oolong tea have substantial capability to obstruct the synthesis of nitrosamines.

Powder Black Tea Application Fields

Tea polyphenols are extensively made use of:
( 1) It can be included in animal fats and oils such as lard, chicken oil, fish oil, lotion, butter, mayo, and veggie fats and oils such as soybean oil, peanut oil, rapeseed oil, camellia oil, corn oil, and palm oil to avoid oils from going rancid. The added quantity is 0.005% to 0.05% of the oil content, and the impact is really substantial.
( 2) Tea polyphenols can be added to foods such as deep-fried potato chips, fried instantaneous noodles, fried peanuts, fried fish, and so on at 0.01% to 0.02% of the oil web content. It has considerable antioxidant results and can prevent The questionable smell from frying fish.
( 3) During the handling of marine items, adding tea polyphenols at a dose of 0.01% to 0.02% can have significant antioxidant, anti-corruption and odorless effects.
( 4) Soak numerous meat items in a remedy prepared with tea polyphenols and other additives. The concentration of tea polyphenols is 0.05% to 0.2%, the saturating time is 5 to 10 minutes, and the remedy temperature is 60 to 70 ° C. At this time, the healthy protein and tea polyphenols externally of the meat items will certainly form a closed dura mater. It can make meat products have antioxidant results, hinder microbial growth and avoid spoilage. In the handling of pickled foods such as ham, sausage, and bacon, adding 0.01% to 0.02% tea polyphenols can not only hinder oxidative spoilage, yet also lower the nitrite web content in pickled foods, making the pickled foods extra scrumptious. The scent.
( 5) Adding Powder Black Tea to dairy items can not only eliminate odor, however likewise protect against the oxidation and perishing of fats and oils in milk items, and can substantially improve the flavor of milk items. The additive dose is typically 0.01% to 0.05%.

Content Determination of Powder Black Tea

Currently feasible approaches for identifying Powder Black Tea primarily consist of ferrous tartrate colorimetric technique, potassium permanganate titration approach and high performance liquid chromatography (HPLC).

The potassium permanganate titration technique has been used for a long period of time and is a simple and very easy method improved on the A.O.A.C method. Nonetheless, this method reveals all substances that can be oxidized. Particularly for crude tea polyphenols with reduced content of tea polyphenols and high material of other impurities (such as Vc, etc), the outcomes are commonly on the high side, and the titration end point is not clear. It is sensitive and difficult to master. Various individuals typically have various titration outcomes, so the error is large.

HPLC can accurately assess the material of catechin monomer, the main element of Powder Black Tea, and can additionally quantitatively evaluate high levels of caffeine at the same time. In this way, the content of caffeine and catechin can be examined at one time, so as to promptly and truly realize the web content of tea polyphenols. quality. Nevertheless, HPLC instruments are pricey and call for high drivers. At the same time, high-purity catechin monomers are hard to buy, so they are not commonly used.

The ferrous tartrate colorimetric approach is easy, quick, easy to master, has high healing rate and good reproducibility. The method stated in my nation’s nationwide requirement for determining the content of tea polyphenols in tea (GB 8313-87) and the industry standard for preservative – tea polyphenols (QB2154-95) is also the ferrous tartrate colorimetric approach. The principle is: Ferrous tartrate can respond with polyphenols to create a blue-violet facility under particular pH problems, and the color depth is favorably associated with the web content of polyphenols in the example. By contrasting the produced shade with the basic shade, the content variety of the polyphenols can be determined a lot more accurately. In real testing, it was located that the above-mentioned blue-violet facility has light absorption at a wavelength of 540nm. Within a suitable focus array, the web content of tea polyphenols is symmetrical to the light absorption of the complex, in line with Lambert-Beer Law, consequently the content of tea polyphenols can be quantitatively determined by spectrophotometry.
