Brief Introduction

Astaxanthin is a natural nutritional component, it can be found as a food supplement. The supplement is intended for human, animal, and aquaculture consumption.

Astaxanthin is a carotenoid. It belongs to a larger class of phytochemicals known as terpenes, which are built from five carbon precursors; isopentenyl diphosphate and dimethylallyl diphosphate . Astaxanthin is classified as a xanthophyll (originally derived from a word meaning “yellow leaves” since yellow plant leaf pigments were the first recognized of the xanthophyll family of carotenoids), but currently employed to describe carotenoid compounds that have oxygen-containing moities, hydroxyl or ketone , such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin and/or canthaxanthin, containing both hydroxyl and ketone functional groups. Like many carotenoids, astaxanthin is a colorful, lipid-soluble pigment. This colour is due to the extended chain of conjugated (alternating double and single) double bonds at the centre of the compound. This chain of conjugated double bonds is also responsible for the antioxidant function of astaxanthin (as well as other carotenoids) as it results in a region of decentralized electrons that can be donated to reduce a reactive oxidizing molecule.

Function:

1.Astaxanthin is a powerful antioxidant and may protect against oxidative damage to body tissues.

2.Astaxanthin can improve the immune response by increasing the number of antibody producing cells.

3.Astaxanthin is a potential candidate to treat neurodegenerative disease such as Alzhimer and Parkinson diease.

4.Astaxanthin dan reduce UVA-light damage to skin such as sunburn, inflammation, ageing and skin cancer.

Application

1.When applied in pharmaceutical field, astaxanthin powder has the good function of antineoplastic;

2.When applied in health food field, astaxanthin powder is used as food additives for pigment and health care;

3.When applied in cosmetic field, astaxanthin powder has the good function of antioxidant and anti-aging;

4.When applied in animal feeds field, astaxanthin powder is used as animal feed additive to impart coloration, including farm-raised salmon and egg yolks.

Biofuel production from woody biomass through the sugar platform requires efficient production of fermentable sugars either chemically and enzymatically by hydrolyzing polysaccharides in wood cell walls. Enzymatic sugar production is a mature technology that can produce high quality sugars but requires a pretreatment step to open wood cell wall structure to improve its accessibility to enzymes, because nature produces wood as a structural material that is not easily accessible to most microbes to deconstruct into basic building blocks such as simple sugars. Unfortunately, pretreatment is the most expensive step in biofuel production through enzymatic saccharification and fermentation. This is especially true for woody biomass due to its high lignin content and strong physical integrity. Pretreatment softwood and harvest softwood forest residue, the feedstock NARA project proposed to use, is even more difficult. Most existing pretreatment processes cannot produce good enzymatic digestibility from softwood. In this webinar, I will outline the basic principles of pretreatment, its limitations, and its effect on downstream co-product development. Especially, I will discuss the SPORL pretreatment NARA adopted for bio-jet fuel production, its versatility, performance, kinetics based process scale-up, and lignin co-product.
