Sweet potato (Ipomoea batatas (L.) Lam) is one of the main crops worldwide. However, systematic properties characterization of this crop is still required, particularly on the Malaysian local sweet potatoes. Hence, this study aims to determine the proximate composition and the energy value of five common varieties of local sweet potato (Anggun 1, Anggun 2, Anggun 3, White, and VitAto) in Malaysia. For each variety, three different parts of the tuberous root which were the skin, the cortex, and the mixture of cambium and parenchyma were characterized. The findings indicated that VitAto exhibited the highest starch (16.95% – 17.17%) and crude protein (0.86% – 1.15%) contents in all parts as compared to other varieties, hence reflecting its potentials to be further processed for a mass starch production. Among all the parts, the skin contained the highest crude protein, crude fat, ash and crude fibre, which can be further utilized to produce by-products such as animal feed. The findings in this study serve as a baseline for the future starch and byproducts production from local sweet potatoes.

Food demand can be found dynamic, altering by the change in price and income. How great the influence of those changes to food consumption is the important information as the basic consideration for government in creating policy related to food consumption. The objective of the research, which has survey design, was to analyze staple food consumption and demand pattern in household in Indonesia. The research was conducted in Bogor, from March to June 2008 by using secondary data Susenas year 2005 with 64.709 households as the samples. The staple food analyzed were rice, corn, cassava, sweet potato, wheat flour and its derived product (instant noodle, noodle). Data was processed by SAS program version 6.12 and Double-Log Regression econometrical model. Then, it was analyzed descriptively. Result shows that rice has the biggest expenditure proportion among staple food. Almost all staple food is obtained by purchasing, except in corn, cassava, and sweet potatoes. Energy contribution from rice reaches half of total energy consumption. The consumption of rice, corn, cassava, sweet potatoes, wheat flour and its derived product, instant noodle, and wheat noodle per capita per year are 100.52 kg, 3.36 kg, 11.67 kg, 4.10 kg, 5.09 kg, 3.39 kg, and 0.22 kg. Staple food which has consumption participation level almost 100% is rice. The own price elasticity of staple foods are not elastic, except in corn, wheat flour and its derived product. The income elasticity of all staple foods is not elastic in all category of region and income stratification. The demand elasticity of staple food give some implications on consumption and food consumption improvement, they are: 1) raising price of staple food can decrease consumption, thus, price stability is very important, 2) almost all staple foods has not elastic income elasticity, so that food consumption improvement needs great stimulus of increasing income, 3) poor household is greatly influenced by the increasing of price, thus, food consumption improvement for them must be conducted by doing many relevant efforts, 4) target of decreasing rice consumption is still cannot be reached, so that staple food diversification must be continuously developed, 5) in order to develop local food consumption, like corn, cassava, and sweet potato, the development of agro industry based on local food and Communication Information Education (CIE) about food consumption diversification are essential to be conducted.

The sweet potato (Ipomoea batatas L.) is relatively known vegetable species, but it is grown only on small area in the Middle European region. Its cultivars are characterized by different colour of tuber flesh which can be white, beige, yellow, orange and purple. The aim of this study was to determine and compare selected qualitative parameters of tubers (total carotenoids, vitamin C and total soluble solids) among orange, white and purple sweet potato cultivars. The field experiments were established at Slovak University of Agriculture in Nitra in 2016 and 2017. Sweet potatoes were grown by hillock system with using of black non-woven textile for soil mulching. The tuber harvest was realised on the 6th October 2016 and 13rd September 2017. The highest content of total carotenoids was found in orange sweet potato cultivars (78.47 - 122.89 mg.kg-1 fresh weight) and its values were multiple-fold higher in comparison with purple (4.22 mg.kg-1 f. w.) and white (10.71 mg.kg-1 f. w.) cultivars. Orange cultivars were also richer source of vitamin C (246.31 - 325.99 mg.kg-1 f. w.) compared to white (179.66 mg.kg-1 f. w.) and purple (187.75 mg.kg-1 f. w.) cultivars of sweet potatoes. The total soluble solids, expressing mainly sugar content, was higher in purple (10.13 °BRIX) cultivar of sweet potatoes, followed by cultivars with orange (8.52 - 9.72 °BRIX) and white (5.57 °BRIX) tuber flesh. Obtained results showed the significant effect of cultivar, characterized by different tuber flesh colour, on the composition and contribution of sweet potatoes for human health.

Germplasm Accessions

Three experiments were conducted with 60 germplasm accessions of yam (Dioscorea spp.) at Plant Genetic Resources Centre of BARI for characterization and conservation of germplasm. Fifty-nine germplasm accessions of D. alata L. and one accession of D. bulbifera L. from different districts of Bangladesh were used. Clockwise twining direction was found in D. bulbifera and anti-clockwise twining direction was exhibited in all D. alata germplasm accessions. Potato like aerial tuber was found in D. bulbifera. Round, oval, elongate, flattened to irregular aerial tuber shape were found. Grayed-brown, brown to grayed-orange skin colour with yellow, yellow-orange to grayed-orange of aerial tuber flesh colour were observed among the yam germplasm accessions. Oval-oblong, cylindrical, flattened, corm, rhizome to irregular shape of underground stem or tubers were observed. Low, medium to dense types of spiniess of roots were found on the tubers. Grayed-orange, red to black tuber skin colour along with white, yellowish-white, yellow, yelloworange, red to purple tuber flesh colours were found. Significant variations were also observed in stem shape at base, colour of stem, wing and petiole wing, position of leaf, leaf shape and distance between leaf lobes. Low to high phenotypic diversity was exhibited among the germplasm accessions. The germplasm accessions produced 1 to 30 under ground tubers per plant. The main tuber length ranged from 5.4 to 66.4 cm and breadth from 2.5 to 15.5 cm. The germplasm accessions produced 0.51 kg to 16.45 kg tuber yield per plant. The maximum variability was found in tuber yield per plant (98.74%) and the minimum was found in leaf length (12.55%).The under ground tubers of yam were harvested and replanted at an interval of two to three years from 1995 at PGRC. The plants were grown on bamboo trail in the field genebank. Necessary intercultural operations are done for maintaining the yam germplasm accessions.
