Summary of "Impact of Nannochloropsis sp. dosage form on the oxidative stability of n-3 LC-PUFA enriched tomato purees."

Microalgae are a sustainable alternative source of n-3 LC-PUFA that can be incorporated into the food chain either via the incorporation of the (intact or disrupted) biomass or by the incorporation of the oil extracted from the biomass. However, the impact of the dosage form on the enrichment of food products with n-3 LC-PUFA and their oxidative stability has never been described before. This study aims to contribute more insight on the impact of the dosage form of the photoautotrophic microalga Nannochloropsis in enriched tomato puree. Three different dosage forms of Nannochloropsis were compared to commercial fish oil and analyzed for their amount of n-3 LC-PUFA, lipid oxidation products, antioxidants and free fatty acids. Tomato purees supplemented with dosage forms derived from Nannochloropsis showed higher oxidative stability than those supplemented with commercial fish oil. The highest oxidative stability was observed for purees supplemented with Nannochloropsis biomass irrespective of whether it was pre-disrupted.

Medical and Biotech [MESH] Definitions

Drugs intended for human or veterinary use, presented in their finished dosage form. Included here are materials used in the preparation and/or formulation of the finished dosage form.

The number of copies of a given gene present in the cell of an organism. An increase in gene dosage (by GENE DUPLICATION for example) can result in higher levels of gene product formation. GENE DOSAGE COMPENSATION mechanisms result in adjustments to the level GENE EXPRESSION when there are changes or differences in gene dosage.

Genetic mechanisms that allow GENES to be expressed at a similar level irrespective of their GENE DOSAGE. This term is usually used in discussing genes that lie on the SEX CHROMOSOMES. Because the sex chromosomes are only partially homologous, there is a different copy number, i.e., dosage, of these genes in males vs. females. In DROSOPHILA, dosage compensation is accomplished by hypertranscription of genes located on the X CHROMOSOME. In mammals, dosage compensation of X chromosome genes is accomplished by random X CHROMOSOME INACTIVATION of one of the two X chromosomes in the female.

A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).

The highest dosage administered that does not produce toxic effects. The NOAEL will depend on how closely dosages are spaced (lowest-observed-adverse-effect level and no-observed-effect level) and the number of animals examined. The ultimate objective is usually to determine not the "safe" dosage in laboratory animals but the "safe" dosage for humans. Therefore, the extrapolation most often required of toxicologists is from high-dosage studies in laboratory animals to low doses in humans.
