Opis:
Algae used in OTC preparations and as functional food are available in the form of finished formulations: powders – lyophilisates, tablets, pills, capsules, and are widely used in cosmetics. In these formulations most commonly used species of algae is cyanobacteria: Arthrospira platensis (Spirulina platensis) and Arthrospira maxima (Spirulina maxima), species of red algae – red algae of the genus Porphyra: Porphyra yezoensis and Porphyra tenera and brown algae – Fucus vesiculosus and green algae for example: Chlorella vulgaris. They are used in cosmetology, pharmacy, food industry, agriculture and environmental protection. Hence, getting to know the current state of the market and knowledge of the preparations containing algae and the promotion of knowledge about their effectiveness is expedient to influence effectively on the prevention of civilization diseases. Conducting a survey on knowledge of the preparations of algae, efficiency and preventive properties may allow to know the current state of knowledge in Poland, about the development of effective promotion in order to use of them. The aim of the study was to assess the knowledge and the possibility of using supplements and food additives containing algae and assessment of the effectiveness of activities in the first reinforcement and anti-aging preparations containing algae in the studied groups of people. Algae due to the fact that are a source of many substances such as amino acids, proteins, minerals, vitamins, polysaccharides, lipids, and polyamides, which are necessary for the proper functioning of the human body, have been used in various industries.

Opis:
The structure-bioactivity relationship of Tremella fuciformis polysaccharides (TFPs) in anti-aging in vivo is rarely reported. In the present study, a purified TFP, named HM, mainly composed of mannose, fucose, xylose, and glucose in a molar ratio of 4.14:0.98:0.81:0.62, was obtained from the fruiting body of T. fuciformis. Subsequently, two differentially degraded TFPs, named MM and LM, respectively, were prepared by a combined method of ultrasonic irradiation (US) and H2O2 treatment. Their structural properties, scavenging activities against free radicals in vitro, and anti-aging effects on D-galactose-induced aging of mice were determined. The average molecular weight of HM, MM, and LM was 58.3×106, 4.68×106, and 3.14×105 Da, respectively. All three TFPs were devoid of triple helix conformation and exhibited concentration- and molecular weight-dependent scavenging activity against radicals. The TFPs markedly relieved skin aging, effectively attenuated oxidative stress, and significantly decreased inflammation in D-galactose-induced aging mice. MM exhibited the best anti-aging effect among the TFPs. Additionally, TFPs partially restored the alterations in pH and the total content of short-chain fatty acids (SCFAs) in the colon but exhibited various impacts on the content of the individual SCFAs. These findings would provide rational guidance for a better application of TFPs in anti-aging foods and expand our understanding of the structure-function relationship of mushroom polysaccharides.
