(1) Background: Arthrospira (commonly known as Spirulina) is an edible cyanobacterium that is produced worldwide as a food supplement owing to its high nutritional value. Arthrospira displays strong potential as an important ingredient in the development of novel functional foods. Polysaccharides from Arthrospira are biologically active compounds and hence there is interest in producing biomass rich in carbohydrates. (2) Methods: A. platensis was cultivated under different degrees of phosphorus limitation in order to trigger the accumulation of carbohydrates. The biomass was then characterized in terms of its content of α- and β-glucans, total dietary fiber and monosaccharide profile. Fourier-transform infrared spectroscopy (FTIR) was used for the rapid analysis of the main biomass components. (3) Results: Phosphorus limitation resulted in an increase in carbohydrates (from 23% up to 65% dry biomass) of which 4–12% (in relation to the dry biomass) was α-glucans and 20–34% was 1.3:1.6 β-glucans, while 1.4:1.6 β-glucans were not detected. Total dietary fibers ranged from 20–32% (of dry biomass), whereas among the carbohydrates, the predominant monosaccharide was glucose (>95%). FTIR performed well when applied as a prediction tool for the main biomass components. (4) Conclusions: Since β-glucans are of particular interest as biologically active compounds, this study demonstrates that phosphorus-limited A. platensis could be a potential ingredient for the development of novel functional foods.

The higher public awareness of the health in community would made the view of some people for food has shifted, not only as relieving hunger, but also can provide a real impact for health. This phenomenon has resulted a term what is called functional food’. Functional food is defined as food which contain active compounds that play a role in increasing endurance, minimize the risk of attack of certain diseases and to provide maximum health benefits. One of marine resource that have a potency to develop as  functional foods is Caulerpa racemosa. Caulerpa racemosa is one of green seaweed that grows naturally in the waters of Indonesia. Caulerpa racemosa found growing on coral substrate or a substrate of sand-rubble. Caulerpa racemosa is edible or can be consumed by humans. Caulerpa racemosa from Indonesia contains high insoluble dietary fiber. Insoluble dietary fiber contains cellulose and hemicellulose, who plays an important role in preventing constipation, colitis and hemmoroid. In other hand Caulerpa racemosa can also produce secondary metabolites, including antioxidants. Antioxidants are substances that are capable of slowing or preventing the oxidation processes that are beneficial to health.Keywords: antioxidant, Caulerpa racemosa, fiber, functional food, health

The term "functional foods" comprises some bacterial strains and products of plant and animal origin containing physiologically active compounds beneficial for human health and reducing the risk of chronic diseases. Among the best known functional compounds probiotics, prebiotics and natural antioxidants should be given as examples. These substances can be obtained by biotechnological methods and by extraction from plant or animal tissues.

With new consumption trends and mindset of a healthier way of life, there is an increasing demand for functional foods. To provide stable and functional products to consumers, the stability of the active compounds must be preserved during the processing of food. For this purpose, encapsulation techniques have been used in various industries in order to overcome problems such as stability, low solubility, and degradation under process conditions for food applications. Electrospinning and electrospraying are two highly versatile and scalable electrohydrodynamic methods, which have gained increasing attention in the various encapsulation applications. This review will give readers an overview of the latest electroencapsulation (electrospraying and electrospinning) of natural bioactive compounds for functional foods applications.

Microalgae are a biochemically diverse assemblage of microorganisms amenable to fermentation and mass culture.Most of these microalgae species produce unique products like carotenoids,antioxidants,fatty acids,enzymes,polymers,peptides,toxins and sterols.Microalgae might become economic sources of new drugs,other specialty chemicals and functional foods because production can be optimized in controlled culture.This paper introduced the biologically active compounds from microalgae and its health function,studies of microalgae in human nutrition and new trends in microalgae food,researched on microalgal health food,and the development of information was provided.

The changes in consumer preferences and the increasingly competitive global market have demanded that food entrepreneurs engage in innovative value-added activities. The date is a delicatessen fruit known by its content of active compounds (e.g., dietary fiber and antioxidants) and its biological activity which has a vast potential in the design of new products such as bioactive ingredients, sugar substitutes, dietary supplements, functional foods, among others. In the current paper, innovative approaches to the value addition to date fruits and their processing by-products have been reviewed from recent high-quality scientific works. New processes such as ultrafiltration and hydrothermal treatments are shown as a useful alternative to obtain differentiated date-based ingredients (e.g., fiber concentrates, sap syrups, and date powders). Moreover, the use of date fruits and their byproducts as natural sources of value-added active compounds in the preparation of dairy, meat, and bakery and cereal products is also presented.
