The effect of pH and temperature on the stability and visual colour of aqueous anthocyanin (ACY) extracts from purpleand red-flesh potatoes was evaluated and compared to commercial ACY extracts from grape and purple carrot. Extracts from purple carrot and redflesh potatoes showed higher stability than grape and purple-flesh potato extracts. Stability to pH (63) and thermal degradation of extrac...

The Sweet potato, Ipomoea batatas (L.) Lam, is difficult to study in genetics and genomics because it is a hexaploid. The sweet potato study not have been performed domestically or internationally. In this study was performed to construct genetic map and quantitative trait loci (QTL) analysis. A total of 245 EST-SSR markers were developed, and the map was constructed by using 210 of those marke...

Four new and two known ether-soluble resin glycosides were isolated from popular sweet potato (the roots of Ipomoea batatas L. LAM., Kokei 14 go, Convolvulaceae) in Japan. Unlike ester-type dimers, batatins I and II, obtained from other sweet potato (Ipomoea batabas var. batatas), the glycosides were tetra or pentasaccharide monomers in which the sugar moieties are partially acylated by organic...

Post-translational regulation plays an important role in cellular metabolism. Earlier studies showed that the activity of plastidial starch phosphorylase (Pho1) may be regulated by proteolytic modification. During the purification of Pho1 from sweet potato roots, we observed an unknown high molecular weight complex (HX) showing Pho1 activity. The two-dimensional gel electrophoresis, mass spectr...

Eight ground beef patty formulations, based on replacing meat with a natural source rich in provitamin A (i.e.carrot and sweet potato) were prepared. All treatments displayed better moisture retention than the controls and hence yield was improved. L, a, and b Hunter values increased and Instron texture profile analysis indicated lower peak forces, increased springiness, and, in some cases cohe...

Diabetes is a disease correlated with the damage of b-pancreatic cells, due to increasing number free-radicals in body, causing body failed produce insulin normal degree, cannot function effectively. In general, diabetic patients suffered from lipid metabolism distortion that would increase total cholesterol level imbalance between and endogenous antioxidants. Purple sweet potato has high antio...

The use of plants and herbs as food supplements and medicinal additives is fast gaining grounds and recognition in the world especially in Africa. Sweet potato leaves (Ipomoea batatas) decoction is a folk remedy for asthma, bugbites, burns, catarrh, diarrhea, fever, nausea, stomach distress and tumours. Also this plant has haematinic effects and has been used in the treatment of anaemia and oth...

This study was subjected to investigate in vitro anti-inflammatory, antioxidant and cytotoxic properties of methanol extracts of two Bangladeshi bean pods namely Lablab purpureus L. sweet ‘white’ and ‘purple’. Protease Inhibition method was used to determine in-vitro anti-inflammatory properties. DPPH free radical scavenging method, total flavonoids, Total antioxidants and reducing power of the...

Research into least fattening eating patterns indicates that in England 'a snack' is a term that refers to different eating habits from 'snacking' and that neither pattern of behaviour necessarily involves 'snack food'. These hypotheses were tested by randomised mailings to a convenience sample of university campus addressees with the subject heading of the message and the topic of questions in...

A novel color control strategy for 3D printing was proposed based on a single channel nozzle with raw material. The basic principle to regulate the pH of extruded line through electrolysis which would result in change pH-sensitive pigments mixed printed materials. Using pulped yam as feedstock and sensitive pigment extracted from purple sweet potato (PPP), process parameters were optimized usin...
