Eighteen brands of potato crisps, frequently consumed, were analyzed to establish their nutritional value in relation to salt, fat and fatty acid (FA) composition. The purpose of the present study was to determine moisture, total fat, salt contents and FA profiles (including trans-FAs), and to
In isolated potato tuber mitochondria, palmitic acid (PA) can induce a H+ leak inhibited by GTP in the phosphorylating (state 3) respiration but not in the resting (state 4) respiration. The PA-induced H+ leak is constant when state 3 respiration is decreased by an inhibition of the succinate uptake
This study was conducted to identify chemicals in root exudates and their effect on Rhizoctonia solani in potato cropping systems. Root exudates were collected from the fields with 5 years of continuous potato cropping in comparison with rotational cropping of potato and other crops, using in-house
Microsomes prepared from pea leaf, potato tuber or germinated soya-beans, were incubated for 30 min with [14C]glycerol 3-phosphate. In the three tissues, phosphatidic acid (PA), CDP-diacylglycerols (CMP-PA) and phosphatidylinositol (PI) were labelled and could be separated by TLC. After methylation
The effects of the purple-fleshed sweet potato extract (PFSPE) on oxidation stabilities of a model oil-in-water emulsion prepared with enzymatically synthesized fish oil-soybean oil structured lipid (SL) versus physically blended lipid (PBL) without modification were evaluated. The anthocyanins in
Quality parameters of potato chips (flat and serrated) fried either in palm oil (PO) alone or containing natural (thyme (TPO) and rosemary (RPO) extracts) and synthetic BHT (BPO) antioxidants were evaluated during storage period. The free fatty acid and peroxide values of chips fried in PO (control)
Pregelatinized maize-sweet potato mix, fortified with soybeans and groundnut flours, was evaluated for its acceptability as a weaning food and for nutrient composition. An acceptable product had 14.3, 6.4, 2.4 and 67.4%, respectively, for its protein, fat, ash and carbohydrate contents. Values for
In six transgenic lines of potatoes with the varying rates of 14-3-3 protein synthesis as well as in control cultivar Desiree the content and composition of the lipids extracted from the mature tubers from three years field trials (1998-2000) were analyzed. The transgenic lines J2 and J1 are both
We previously found no difference in healthy young adults' plasma cholesterols between palmolein and olive oil as the major dietary lipid, although the former is high in palmitic acid (16:0) but the latter in oleic acid (18:1 cis). In the experiment reported here we compared the effects of palmolein
Phospholipase (PL) A2 is involved in signal transduction in the resistance reaction that is induced in potato by inoculation of an incompatible race of Phytophthora infestans, the late blight fungus, or by treatment with fungal elicitor hyphal wall components (Kawakita et al. 1993). In this study,
Use of potato processing wastewater for microbial lipid production by oleaginous filamentous fungus Aspergillus oryzae was studied with the purpose of recycling potato processing wastewater for biodiesel production. The wastewater contained high concentrations of solids, starch and nutrients.
Total and individual fatty acid contents were determined in raw tubers of four genotypes from each of the two species Solanum phureja and S. tuberosum. The four S. phureja genotypes contained statistically significantly higher concentrations of total fatty acids, with their average value being 37%
Little is known about the fungal metabolism of nC10 and nC11 fatty acids and their conversion into lipids. A mixed batch culture of soil fungi, T. koningii and P. janthinellum, was grown on undecanoic acid (UDA), a mixture of UDA and potato dextrose broth (UDA+PDB), and PDB alone to examine their
To find out the potential condition for diapause induction in the potato tuber moth Phthorimaea operculella (Zeller), combination of constant temperatures (15, 20, and 30°C) and photoperiods (8, 9, 10, 11, 12, 14, and 16 h) were employed from egg to adult emergence. In addition, changes in the total
This paper represents a comprehensive study of two new thraustochytrids and a marine Rhodotorula red yeast isolated from Australian coastal waters for their abilities to be a potential renewable feedstock for the nutraceutical, food, fishery and bioenergy industries. Mixotrophic growth of these
