Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...

Potato yields in sub-Saharan Africa remain very low compared with those of developed countries. Yet potato is major food staple and source of income to the predominantly smallholder growing households in the tropical highlands of this region. A major cause of the low potato yields is the use of poor quality seed potato. This paper examines the factors determining the decision to use certified s...

to identify the alternaria spp. pathogenic to tomato and potato, surveys of tomato and potato fields were made during 2009- 2010 in west azerbaijan province. in total about 261 isolates belonging to alternaria genus were isolated and purified. based on morphological studies 6 species, namely: a. alternata, a.tenuissima, a. interrupta, a. arborescense, a. brassicina and a. tomatophila from tomat...

We have previously showed that Schistosoma mansoni ATP-diphosphohydrolase and Solanum tuberosum potato apyrase share epitopes and the vegetable protein has immunostimulatory properties. Here, it was verified the in situ cross-immunoreactivity between mice NTPDases and anti-potato apyrase antibodies produced in rabbits, using confocal microscopy. Liver samples were taken from Swiss Webster mouse...

A recently synthesized kairomone blend, based on the volatiles produced by potato (Solanum spp.) plants, has been demonstrated to be attractive to both adult and larval stages of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). It was subsequently formulated in a viscous inert carrier for field applications and showed potential for aggregating beetles in ...

The objective of this work was carried out to study the evaluate air frying process as a new technique for frying process. The Potato strips were fried in both air-frying machines (Tefal Actifry) at 180oC±5oC for 40 min and traditional frying process at 180oC for 40 min, 6 min/batch. After frying, the moisture and oil uptake were determined. Changes in some physico-chemical properties of oil ex...

Rapid expansion of the processing potato industry has contributed to a significant increase in irrigated potato production in Manitoba. However, information is lacking regarding optimum rotations for local conditions. In 1998, a crop rotation study was initiated on a Wellwood silt loam near Carberry to identify crop rotations that optimized crop yield and quality while maintaining soil quality....

BACKGROUND Orange-fleshed sweet potato is an efficacious source of vitamin A. Substituting wheat flour with orange-fleshed sweet potato in processed products could reduce foreign exchange outlays, create new markets for producers, and result in increased vitamin A consumption among consumers provided there is adequate retention of beta-carotene during processing. OBJECTIVE To explore whether ...

A full-length cDNA copy of the genome of Potato leafroll virus (PLRV) was introduced into the genome of tobacco and potato plants by Agrobacterium tumefaciens-mediated transformation. Transgenic lines were obtained in which the transgene was readily detected by PCR with DNA extracted from T(1) tobacco seedlings and clonally multiplied potato plants. PLRV-specific genomic and sub- genomic RNAs, ...

BACKGROUND Acrylamide as a possible carcinogen is known to form in heated carbohydrate-rich food such as potato chips. In this study, the effect of three potato varieties (Agria, Sante and Savalan) and two blanching conditions (75 °C for 9 min and 83 °C for 2.5 min) on the concentration of precursors and acrylamide reduction in potato chips was investigated. RESULTS Results revealed that pota...
