“…Non-conventional methods, which are more environmental friendly due to decreased use of synthetic and organic chemicals, reduced operational time, and better yield and quality of extract, have been developed during the last 50 years. To enhance overall yield and selectivity of bioactive components from plant materials, ultrasound (Vinatoru et al, 1997;Ghafoor et al, 2011), pulsed electric field (Toepfl et al, 2006), enzyme digestion (Gaur et al, 2007), extrusion (Lusas and Watkins, 1988), microwave heating (Kaufmann and Christen, 2002), ohmic heating (Lakkakula et al, 2004), supercritical fluids (Marr and Gamse, 2000;Lang and Wai, 2001;Meireles and Angela, 2003;Wang et al, 2008;Ghafoor et al, 2010Ghafoor et al, , 2012, and accelerated solvents (Kaufmann and Christen, 2002;Smith, 2002) have been studied as non-conventional methods. At the same time conventional extraction methods, such as Soxhlet is still considered as one of the reference method to compare success of newly developed methodology.…”

“…More specifically, ultrasound has been reported for the extraction of Sargassum pallidum (Ye et al, 2008), which belongs to the same genus as Sargassum fusiforme. It has been proved that the ultrasonic treatment has mechanical effects that facilitate the disruption of cell walls, and enhances mass transfer of the cell contents as a result of cavitation bubble collapse (Vinatoru et al, 1997). The problem is that ultrasonic wave has degradation effects on polysaccharides Optimization of polysaccharides extraction An orthogonal L 9 (3 3 ) test design was used to investigate the optimal extraction condition of polysaccharides from Sargassum fusiforme.…”

An ultrasonic-assisted extraction method was employed to get high quality bioactive polysaccharides from Sargassum fusiforme (SFP), with the technology optimized in light of an orthogonal test design L 9 (3 3 ). Being the major factors that influence the yield of the extracts, the ultrasonic power, water/solid ratio, and extraction time were selected on the basis of a single-factor test. The extraction yield and the antioxidant activity of SFP were used as dependent variables in the analysis of the orthogonal test results. The antioxidant activity of SFP was evaluated using IC 50 of scavenging 1,1-diphenyl-2-picrylhydrazyl (DPPH) as the activity monitoring parameter. The optimum extraction conditions were obtained when the ultrasonic power, the extraction time, and the ratio of water to solid were 800 W, 10 min and 20, respectively. Under the optimized conditions, the SFP extracted with the optimized ultrasonic-assisted method exhibited strongest DPPH radical scavenging activity (P < 0.05) compared with conventional hot water extracted SFP and other two antioxidants.Keywords: Sargassum fusiforme, polysaccharides, orthogonal experiment, extraction, antioxidant *To whom correspondence should be addressed. E-mail: qiangy@zwu.edu.cn IntroductionSargassum fusiforme, the brown alga, is one of the most widely consumed seaweeds in China, Japan and Korea, not only as food, but also as herbal medicine. As an important economic alga, it is now cultured on a vast scale in coastal zone in China's Zhejiang and Fujian provinces (Huang et al., 2006). The polysaccharides extracted from Sargassum fusiforme (SFP) in medicine are polymeric carbohydrate structures and have widely been suggested as antioxidants (Siriwardhana et al., 2004), anti-coagulants (Kim et al., 1998, and tumor inhibitor (Han et al., 2009) because of their chemical properties and biological activities (Zhu et al., 2010). However, the utilization of SFP currently is restricted by its polysaccharides extraction technology, which is fundamental for its application or further research and development.The conventional and most common extraction method for polysaccharides is the hot water extraction (HWE) method and many papers have been aimed at investigating the influence of extraction parameters, such as particle size, ratio of solvent to raw material, extraction time, extraction temperature, pH value and number of extraction (Wang et al., 2009a. It should be noted that HWE of polysaccharides is always time-consuming, laborious and polysaccharides losing. To solve these problems, the acid extraction method came into being. This method is not without its flaws, however. It may easily alter the structure of the polysaccharide related immunocompetence (Abdel-Fattah et al., 1974). Therefore, alternative extraction techniques like the microwave-assisted extraction (MAE) and ultrasonic assisted extraction (UAE) technologies have attracted considerable interests and have been employed to extract polysaccharides from different plant materials, including Cyclocarya paliuru...

-The increasing amount of food waste througout the world is becoming a major problem for waste management plants. The food waste produced amounts to 1.3 million tons a year. This is a resource that could be used for production of new products. Decreasing fossil resources and a rapidly growing population lead to the necessity to produce more food and to replace existing with new materials ones that are biological and produce little effect on environment. Bioeconomy is a method that can help achieve production of value-added products that use local resources and waste to manufacture products efficiently. In this article, we are looking at possibilities to use potatoes for production of new materials, such as bioplastics, antioxidants, proteins, instead of their conventional use for food production. We have studied potato components, extraction technologies and summed up possible directions for development for new products, looking at the use of processing waste as a raw material.
