Marine Cryptophytes Are Great Sources of EPA and DHA

2017

Microalgae have the ability to synthetize many compounds, some of which have been recognized as a source of functional ingredients for nutraceuticals with positive health effects. One well-known example is the long-chain polyunsaturated fatty acids (PUFAs), which are essential for human nutrition. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the two most important long-chain omega-3 (-3) PUFAs involved in human physiology, and both industries are almost exclusively based on microalgae. In addition, algae produce phytosterols that reduce serum cholesterol. Here we determined the growth rates, biomass yields, PUFA and sterol content, and daily gain of eight strains of marine…

Microalgae and seaweeds for food applications: Challenges and perspectives

Influence of different sources of vegetable, whey and microalgae proteins on the physicochemical properties and amino acid profile of fresh pork saus…

2019

Abstract The purpose of this study was to evaluate changes in the physicochemical properties and amino acid profiles of pork sausages prepared by including vegetable protein sources (beans, peas, and lentils), microalgae (Chlorella and Spirulina) or whey, as compared with a control (soy protein). Significant differences were found for all the studied parameters. The protein content was significantly lower in sausages made with pea protein compared with the control. Colour parameters changed significantly after the incorporation of microalgae proteins. Moreover, significant differences among treatments were observed in the amino acid profile. The inclusion of Spirulina proteins resulted in a…

Diet Quality Limits Summer Growth of Field Vole Populations

2014

Marked variation occurs in both seasonal and multiannual population density peaks of northern European small mammal species, including voles. The availability of dietary proteins is a key factor limiting the population growth of herbivore species. The objective of this study is to investigate the degree to which protein availability influences the growth of increasing vole populations. We hypothesise that the summer growth of folivorous vole populations is positively associated with dietary protein availability. A field experiment was conducted over a summer reproductive period in 18 vegetated enclosures. Populations of field voles (Microtus agrestis) were randomised amongst three treatment…

Biochemical characterization of cassiopea andromeda (Forsskål, 1775), another red sea jellyfish in the western mediterranean sea

2021

Increasing frequency of native jellyfish proliferations and massive appearance of non-indigenous jellyfish species recently concur to impact Mediterranean coastal ecosystems and human activities at sea. Nonetheless, jellyfish biomass may represent an exploitable novel resource to coastal communities, with reference to its potential use in the pharmaceutical, nutritional, and nutraceutical Blue Growth sectors. The zooxanthellate jellyfish Cassiopea andromeda, Forsskål, 1775 (Cnidaria, Rhizostomeae) entered the Levant Sea through the Suez Canal and spread towards the Western Mediterranean to reach Malta, Tunisia, and recently also the Italian coasts. Here we report on the biochemical characte…

Mycotheca of Edible and Medicinal Mushrooms at Herbarium SAF as a Potential Source of Nutraceuticals and Cultivated Mushrooms

2018

Basidiomycetes strains (n = 39) belonging to 9 genera in 8 families are kept in the mycotheca of the Department of Agricultural, Food and Forest Sciences at the University of Palermo (Palermo, Italy). All of the strains are medicinal mushrooms, and some are of great commercial and nutraceutical interest.

Influence of the addition of different origin sources of protein on meat products sensory acceptance

2019

The effect of the addition of different protein sources on the sensory properties of meat products was evaluated. Pork liver pâte, turkey patties, cooked turkey breast, fresh pork sausages, and marinated turkey breast were elaborated with soybean (control), and other protein sources, such as aspea, lentil, bean, Chlorella, Spirulina, and dairy protein. Physicochemical parameters (pH, color, and hardness), taste profile, acceptance, and preference were assessed. The incorporation of different protein sources in meat products modified the sensorial characteristics, which differentially influenced the acceptance of panelists, generating panelist groups with different preference profiles. Meat …

Ecological mechanisms can modify radiation effects in a key forest mammal of Chernobyl

2019

International audience; Nuclear accidents underpin the need to quantify the ecological mechanisms which determine injury to ecosystems from chronic low-dose radiation. Here, we tested the hypothesis that ecological mechanisms interact with ionizing radiation to affect natural populations in unexpected ways. We used large-scale replicated experiments and food manipulations in wild populations of the rodent, Myodes glareolus, inhabiting the region near the site of the Chernobyl disaster of 1986. We show linear decreases in breeding success with increasing ambient radiation levels with no evidence of any threshold below which effects are not seen. Food supplementation of experimental populatio…
