The effect of osmotic and convective drying treatments on main physicochemical properties frozen sliced red peppers was investigated. Sliced were dried partially using either dehydration or hot air before freezing in an blast freezer at constant velocity (2 m/s) temperature (-25°C). center osmo- dehydrofrozen reached -25°C about 105 min, while it took 270 min for control samples. Frozen samples...

BACKGROUND The plant Alisma plantago-aquatica Linnaeus, which is widely distributed in southwest of China, is the main material of traditional Chinese medicine "Zexie". It was used as folk medicine for immune-modulation, anti-tumor, anti-inflammatory and antibacterial. Previous chemical studies on A. plantago-aquatica reported the identification of triterpenes, diterpenes, sesquiterpenes, stero...

In their comprehensive work on 2acetylaminofluorenel (Fig. 1) the Weisburgers and Morris (l-4) have identified six phenolic metabolites of this carcinogen in the urine of adult rats. During recent studies (5) on this compound we have encountered a new acidic urinary metabolite. This metabolite is of interest since its excretion is greatly reduced by administration of a-methylcholanthrene, a pot...

Ready-to-eat baby-leaf vegetables market has been growing and offering to consumers convenient, healthy and appealing products, which may contain interesting bioactive compounds. In this work, the composition and the evolution of the phenolic compounds from different baby-leaf vegetables during refrigerated storage was studied. The phenolic compounds were extracted using pressurized liquid extr...

233 Plantains and bananas (Musa sp.) are important starchy staples in Ghana. Processing of plantains into flour is limited as most plantain foods are eaten as boiled, fried or roasted. However, after the introduction on local and foreign markets of instant plantain fufu (popular West African food) flour consisting of plantain flour and cassava starch, interest in plantain flours as a commercial...
