[What is green tea extract]

Green tea is the second largest beverage demanded by consumers worldwide. Used in China and India for its medicinal effects. There are several compounds extracted from green tea including catechins which contain an enormous amount of hydroxyphenols that are easily oxidized, congregated and contracted, which explains its good anti-oxidation effect. Its anti-oxidation effect is 25-100 times as strong as those of vitamin C and E.

It is widely used in medicines, agriculture, and chemical and food industries. This extract prevents cardio-vascular disease, lowers the risk of cancer, and decreases blood sugar and blood pressure, as well as viruses. In the food industry, the anti-oxidation agent used for preserving food and cooking oils.

[Function]

1. Green tea extract can reduce blood pressure, blood sugar, blood lipids.

2. Green tea extract has the function of removing radicals and anti-aging.

3. Green tea extract can enhance the immune function and prevention of colds.

4. Green tea extract will anti-radiation,anti-cancer, inhibiting the increasing of cancer cell.

5. Green tea extract used to anti-bacterium, with the function of sterilization and deodorization.

[Application]

1.Applied in cosmetics field, Green tea extract owns the effect of anti-wrinkle and anti-Aging.

2.Applied in food field, Green tea extract is used as natural antioxidant, antistaling agent, and anti-fading agents.

3.Applied in pharmaceutical field, Green tea extract is used to prevent and cure cardiovascular disease, diabetes.

QAAFI SCIENCE SEMINAR SERIES
28 March 2017

DESCRIPTION
The structure and material properties of growing and fleshy plant tissues are determined by their (primary) cell walls. The biological requirement in growing tissues for cell walls to combine structural strength with flexibility and extensibility is met through a network of cellulose fibres in a hydrogel form that is modified by the presence of other polysaccharides. From direct measurement on isolated plant cell walls and using a model bacterial cellulose hydrogel system, the molecular rules governing the association of non-cellulosic polysaccharides with cellulose fibres have been deduced. The effects of various features of cell wall hydrogels on the characteristic material properties under small deformation, compression and extension have been characterized and rationalized. Consequences for plant material properties and plant food behavior in the digestive tract will be discussed.

About Prof. Mike Gidley
Professor Mike Gidley is Director of the Centre for Nutrition and Food Sciences (CNAFS) in QAAFI. Prof. Gidley’s career includes 22 years in food R&D in the private sector and the last 13 years at UQ in the Centre for Nutrition and Food Sciences.

Research themes within CNAFS include ‘Smart Selections’ (how to identify the right combinations of raw materials and processing to deliver consumer-preferred foods), ‘Naturally Nutritious’ (maximising the intrinsic nutritional properties of agricultural products in foods and ingredients) and ‘Uniquely Australian’ (identifying and validating opportunities for elite products from foods and ingredients that can only have come from Australia).

Prof. Gidley’s own research is focused on structure – function relationships in important food components such as starch granules and plant cell walls. This has led to the detailed characterisation of starch and dietary fibre digestion/fermentation in vitro and in vivo, with the understanding generated leading to opportunities for optimising nutritional value of foods and feeds. He is a Program Leader in the Australian Research Council Centre of Excellence in Plant Cell Walls (2011-2017)
