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.

The objective of the present study was to differentiate and compare the proximate composition, minerals, flesh colour, phenolic composition, and antioxidant activities of varieties of white-fleshed sweet potato (WFSP) and potato (WFP) locally grown in Pakistan. The results showed that WFP presented higher moisture and crude fat content, while WFSP offered better ash, crude protein, and crude fibre contents. Colour analysis revealed that WFSP and WFP showed the highest L* (lightness) values and exhibited the maximum total phenolic content and total flavonoids content of 9.27 ± 0.88 mg GAE/g and 19.01 ± 0.66 mg QE/g. In vitro, results demonstrated that WFSP possessed better antioxidant activity with the highest ferric reducing antioxidant power of 58.67 ± 0.22 mM Fe2+/g and DPPH scavenging activity of 39.12 ± 0.33% compared to WFP. It is concluded that WFSP possesses a better proximate and mineral profile followed by higher antioxidant activity.

Background Protein-energy deficiency (PEM) is still a major health issue in developing countries, and it is the leading cause of disease and death in children under the age of 5 years. Methods 100:0:0; 90:5:5; 80:10:10; 70:15:15; 60:20:20; and 50:25:25 per cent wheat:haricot bean: orange-fleshed sweet potato (OFSP) flours were used to make composite cookies. Standard methods were used to evaluate the proximate structure, physical properties, and sensory assessment. A one-way analysis of variance (ANOVA) model was used to statistically evaluate the data using the statistical analysis system (SAS) software package, version 9.0 standard methods. Results The results showed that partially replacing wheat with haricot bean and OFSP increased the proximate composition significantly. When wheat was replaced with haricot bean and OFSP, the physical characteristics of the biscuits did not vary significantly from those of biscuits made entirely of wheat flour. Sensory acceptability (appearance, color, flavor, taste, and overall acceptability) was higher in the composite biscuits with up to 40% wheat substitution than in the 100% wheat flour biscuits. Conclusions Based on the findings of this report, using OFSP and a haricot bean to wheat flour blend in biscuit formulation appears to be promising in terms of nutritional quality, acceptability, and cost. It is proposed that these products be marketed to vitamin A deficiency (VAD) customers as a newly established product to help mitigate food insecurity.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins

<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>
