Environmental and Varietal Influences on the Fatty Acid Composition of Rapeseed, Soybeans and Sunflowers

JOURNAL OF AGRONOMY AND CROP SCIENCE, Issue 1 2010
M. Werteker
Abstract The fatty acid (FA) composition of oil crops is of some importance under technological as well as under nutritional aspects. The influence of temperature on this parameter in rapeseed, soybeans and sunflowers was investigated under practical agricultural conditions, whereby varietal variations were taken into account. The analysed plant material originated from variety testing trials located in different climatic zones of Austria. As a measure of the climatic conditions of a location, the mean temperature of the last 30 days before harvest was calculated. Despite the low temperature differences between the various locations, moderate but significant negative correlations between temperature and the share of linolenic (18 : 3), respectively, linoleic (18 : 2) acid on the whole quantity of FAs in rapeseed (RČ = 0.18,0.42), soybeans (RČ = 0.11,0.13) and sunflowers (RČ = 0.15) were found. Furthermore, there was a good negative correlation in the case of sunflower seeds between temperature and oil level (RČ = 0.45). The environmental influence on the share of polyunsaturated FAs differed between the different species. The results show that quality of vegetable oils is as well a question of environment as of variety. [source]


PRELIMINARY STUDIES ON PHYSICAL AND NUTRITIONAL QUALITIES OF SOME INDIGENOUS AND IMPORTANT RICE CULTIVARS OF NORTH-EASTERN HILL REGION OF INDIA

ABSTRACT The northeastern hills of India are endowed with rich source of rice germplasm, which may be safely estimated about 9,000 accessions, excluding the redundancies. Even though much of the germplasm have been collected, studies on nutritional aspects of these local cultivars are still lacking. Fifteen important indigenous rice genotypes collected from different rice growing ecosystem of this region were studied for physical and nutritional qualities. Kernel color of the genotypes varied from white to dark purple. All the genotypes except Manipuri were of bold-grain type. Most of the genotypes studied have fat contents more than 2.0%. The protein content was found higher in Chahou angouba and Naga special. Five cultivars were identified as high-protein cultivars of rice, with 10,12.07% protein content. Amylose content varied from 2.27 to 24.5%. Most of long-grained genotypes recorded lesser amylose than short grained. Chahou varieties were found aromatic and glutinous, which demand higher market prices in local market. PRACTICAL APPLICATION The north-eastern hills of India are endowed with rich source of rice germplasm, and much of the germplasm have been collected, but studies on basic and advanced nutritional aspects of these local cultivars are still lacking. This part of India has valuable rice genotypes of strong aroma, glutinous characters and slender grains with high amount of protein, fat and fiber. Having not known to the rest of the world and even to indigenous end users, some of such cultivars have already been lost, and some more are at the verge of extinction. Quality evaluation done in the present study provided useful information on their commercial exploitation and utilization in breeding programs of nutritional enhancement of rice to fight malnutrition among rice-consuming population, which is largest in the world.

Composition, nutritional aspects and effect on serum parameters of marine algae Ulva rigida

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 3 2010
Cristina Taboada
Abstract BACKGROUND: Algae are commonly consumed in Asia and have also gained popularity in Europe. However, data on the bioavailability of their components are limited. The present study was designed to determine the composition of Ulva rigida and the effects of inclusion of 10% of the algae in a standard diet for 4 weeks on nutritive value and serum parameters in order to consider the usefulness of Ulva as a dietary supplement. RESULTS:Ulva rigida is rich in protein, carbohydrates, fibre, vitamins and minerals and has a low lipid content. Analysis of the amino acid composition revealed good-quality protein. The algae were well accepted by experimental animals and did not significantly change nutritional parameters but reduced LDL cholesterol. CONCLUSIONS:Ulva rigida is an excellent source of nutrients and could improve a balanced diet. Further studies are required to research the potential of the seaweed as a natural source of bioactive compounds. Copyright © 2009 Society of Chemical Industry [source]


Nutritional Value of Edible Seaweeds

NUTRITION REVIEWS, Issue 12 2007
Paul MacArtain PhD
This article presents information on the nutritional aspects of seaweeds in terms of fiber, mineral content, fats and lipids, vitamin contents, and components that have a confirmed and investigated nutritional effect. The nutrient levels of seaweeds are also shown in comparison to currently applicable reference nutrient intakes or guideline daily amounts of nutrients and are contrasted with terrestrial foodstuffs with respect to selected nutrients. For the purpose of comparison, a sample serving size of 8 g dry weight of seaweed is used to illustrate the potential contribution of seaweeds to the diet. [source]
