Amylolysis of native and annealed potato starches following progressive gelatinisation

Food Hydrocolloids, 2014
Abstract The extent of α-amylase hydrolysis of normal potato starches, extracted from different varieties grown under the same conditions in the same season, is regulated more by gelatinisation than the composition or structure of the granules. This is evident for native and annealed starches gelatinised and then hydrolysed with α-amylase.

Anthocyanin synthesis in native and wound periderms of potato

Physiologia Plantarum, 2014
Skin color of red potatoes is due to accumulation of anthocyanins in the tuber periderm, a protective tissue that replaces the epidermis at an early stage of tuber development. The periderm consists of external layers of suberized phellem cells making up the skin, and internal layers of parenchyma‐like phelloderm cells. Red pigmentation is an important

Gelatinisation properties of native and annealed potato starches

Starch - Stärke, 2011
AbstractThe relationship between the gelatinisation parameters of native and annealed starches extracted from ten different potato varieties grown at the same site at the same time was studied. The objective was to identify how native gelatinisation temperatures and enthalpies impacted on annealed starch gelatinisation parameters.

Knowledge System Dynamics Andean Native Potato Production

Rural Review: Ontario Rural Planning, Development, and Policy
Background: Indigenous Knowledge Systems of rural Campesino communities in the Peruvian Andes are critical for ongoing maintenance and conservation of local food systems, supporting communities’ food and nutrition security while stewarding native potato genetic diversity.

NATIVE PREDATORS AND THE CONTROL OF POTATO APHIDS

The Canadian Entomologist, 1986
AbstractExperiments were done in fields of potato in Fredericton, New Brunswick, in 1981, 1982, and 1984 to determine the effect of native predators on the abundance of aphids. The populations of predators were altered by pitfall trapping within plots enclosed by polythene barriers and by applying a selective insecticide.

Native protein recovery from potato fruit juice by ultrafiltration

Desalination, 2002
Potato fruit juice, i.e. the stream resulting after the extraction of the starch from the potato, contains up to 2.5% [w/w] of proteins that are potentially valuable for the food market. However, today the recovery of protein from the potato fruit juice with reverse osmosis membranes results in a protein concentrate that is not suitable for human ...

Infection of Native Solanum Species by the Potato Blight Fungus

Nature, 1957
SINCE the discovery of Phytophthora infestans (Mont.) de Bary on the New Zealand shrub Solanum aviculare Forst.1 in native bush near Auckland by Miss J. M. Dingley, many other infected plants of this species have been found in both the North and South Islands (Brien, R. M., personal communication).

Improving Potato Storage and Processing Characteristics through All-Native DNA Transformation

Journal of Agricultural and Food Chemistry, 2006
The dominant potato (Solanum tuberosum) variety for French fry production in the United States is the 131-year-old Russet Burbank. Market penetration of the higher yielding and more uniform Ranger Russet variety is limited to about one-fifth of that of the Russet Burbank because of two storage deficits: black spot bruise sensitivity and high levels of ...

Molecular and cytological aspects of native periderm maturation in potato tubers

Journal of Plant Physiology, 2013
Mature native periderm that exhibits resistance to excoriation (RE) is the primary defense for potato tubers against abiotic and biotic challenges. However, little is known about the physiology of periderm maturation and associated gene expressions. In this study, periderm maturation events and associated gene expressions were determined in tubers of ...
