“…Enteromorpha prolifera (EP), a green alga, grows in seashores, particularly in East Asia. From ancient times, EP has been used in food diets as well as in traditional remedies for treating epistaxis and inflammation, fever, and hydrops fetalis [ 27 , 28 , 29 , 30 ]. EP contains various nutrients, such as vitamins, phytochemicals, and polyunsaturated fatty acids and abundant phytochemicals, including carotenoids, flavonoids, phenolic compounds, phycocyanin, and chlorophyll, which were reported to have biological activities including antioxidant, anti-inflammatory, and anti-diabetes effects [ 31 , 33 , 35 ].…”

Enteromorpha prolifera, a green alga, has long been used in food diets as well as traditional remedies in East Asia. Our preliminary study demonstrated that an ethyl acetate extract of Enteromorpha prolifera (EAEP) exhibited the strongest antioxidant activity compared to ethanol or water extracts. Nonetheless, there has been no report on the effect of EAEP on memory impairment due to oxidative damage. This study investigated whether EAEP could attenuate memory deficits in an oxidative stress-induced mouse model. EAEP was orally administered (50 or 100 mg/kg body weight (b.w.)) to mice and then scopolamine was administered. The oral administration of EAEP at 100 mg/kg b.w. significantly restored memory impairments induced by scopolamine, as evaluated by the Morris water maze test, and the passive avoidance test. Further, EAEP upregulated the protein expression of BDNF, p-CREB, p-TrkB, and p-Akt. Moreover, EAEP downregulated the expression of amyloid-β, tau, and APP. The regulation of cholinergic marker enzyme activities and the protection of neuronal cells from oxidative stress-induced cell death in the brain of mice via the downregulation of amyloid-β and the upregulation of the BDNF/TrkB pathway by EAEP suggest its potential as a pharmaceutical candidate to prevent neurodegenerative diseases.

In this study, 1, 3, and 5% of Enteromorpha prolifera (E. prolifera, green laver) powder was added to the rice crispy cereal, a gluten-free food. The quality characteristics and antioxidant activities of rice crispy cereal were investigated. The reducing sugar content decreased with increased contents of E. prolifera powder. In the Hunter color system, the L and a values decreased, while the b values increased with increasing E. prolifera content. The phycocyanin and chlorophyll contents (antioxidant pigments) increased with increasing amounts of E. prolifera. The 5% E. prolifera additive group exhibited the maximum antioxidant and radical (DPPH and hydroxyl) scavenging activities. The flavonoid and total phenolic contents were also the maximum in this group. The intensity test results revealed that rice crispy cereal containing 5% E. prolifera exhibited the highest overall acceptability. Based on these results, The study presents the preliminary data that can be used to improve the nutritional value of rice crispy cereal. The results revealed that powdered E. prolifera can be added in different proportions to various types of food for the development of different food items having varying properties. Key words：Enteromorpha prolifera, rice crispy cereal, quality characteristics, antioxidant activities
