We studied the influence of powdered green tea (PGT) and its caffeine content
on the adipose conversion of 3T3-L1 cells by insulin and lipolysis of well-differentiated
3T3-L1 cells. In the 11 days of culture with insulin, the fat cells exhibited
more numerous and larger intracytoplasmic lipid droplets, and the activities
of glycerophosphate dehydrogenase (GPDH), a marker of adipose conversion,
were increased. When PGT and insulin were added simultaneously, the accumulation
of lipid droplets and the increase of GPDH were significantly inhibited
(p<0.01). But the caffeine, which has the same concentration as PGT,
accelerated adipose conversion. When PGT or caffeine was exposed to mature
adipocytes, smaller-sized intracytoplasmic lipid droplets selectively disappeared.
These data suggest that PGT inhibited lipogenesis and stimulated lipolysis. |

Why I believe it is worth to introduce powdered green tea (Sencha) to you.
Green tea can be enjoyed by consuming the leaves directly. Actually, Japanese have cooked and eaten green tea leaves traditionally.
Since the most effective green tea nutrients are not water soluble, about 70% of these ingredients remain in used tealeaves. However, you can intake all of those beneficial components, if you consume the leaves directly.
Powdered green tea (Sencha) is different from powdered Gyokuro, which is well known as Matcha. Gyokuro is made from tealeaves that grown with covering on them to avoid sunlight. As a result, Gyokuro contains less Catechin than Sencha. |
Why purchase from us?
Most manufacturers use high-speed rotating powder machine to produce powdered green tea. This method is efficient in manufacturing, but causing destruction of vitamins and browning.
We grind high grade tealeaves gently to its finest form and can be produced only 10kg. in 30 hours. In doing so, our powdered green tea has no destruction of vitamins and browing, and achieved consistent quality.
Our powdered green tea do not dissolve in (hot) water.
When you pour (hot) water, it seems like dissolved. However, it will be precipitated over time. This is because we do not use any additive, such as that to promote dissolution, and artificial color.
From the nature of things, powdered green tea do not dissolve in (hot) water. Because it is tealeaves ground to powder form.
Our powdered green tea is made from 100% quality Sencha leaves without any additives.
