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.

Roasting can increase the Maillard reaction and caramelization of sweet potatoes to create an attractive appearance, color, aroma, and taste, and is rapidly increasing in the commercial market. This study mainly analyzed the influence of roasting sweet potatoes, with and without the peel, on sweet potato quality and flavor characteristics combined with sensory qualities. The results showed that the a* value (1.65–8.10), browning degree (58.30–108.91), total acidity (0.14–0.21 g/100 g, DW), and maltose content (0.00–46.16 g/100 g, DW) of roasted sweet potatoes increased with roasting time. A total of 46 volatile compounds were detected and 2-furanmethanol, furfural, and maltol were identified as the main sources of the aroma of roasted sweet potatoes. A sensory evaluation based on a comprehensive nine-point acceptance test and descriptive analysis showed that roasting for 1 to 2 h resulted in the highest acceptance score (6.20–6.65), including a golden-yellow color, sweet taste, and fibrous texture. The sweet potatoes became brown after roasting for 2.5 to 3 h and gained a burnt and sour taste, which reduced the acceptance score (4.65–5.75). These results can provide a reference for increased quality in the food industry production of roasted sweet potatoes.

The aim of the work was to produce and characterize the exopolysaccharides from loss cooked sweet potato (Ipomoea batatas) using fermentation with Lactobacillus. The cooked sweet potato was fermented according to the factorial design with the following factors: the time (21.51h-38.48h) and the amount of Lactobacillus (1.58*106-5*106UFC). Responses were represented by production yield, pH, and titrable acidity. Characterization of the exopolysaccharides was then done by determination of total sugars, solubility index and viscosity. The results show that the pH of unfermented cooked potatoes was between 6.23 to 6.63. The pH of fermented potatoes varies from 3.96 to 4.06. The lactic acid content was found from 7.75 to 9.9% for the fermented samples. The production yields are 1.90% for the samples fermented for 21.5 hours with 3.5*106UFC of bacteria and 5.62% for those fermented for 30 hours with the same volume of inoculum. The average viscosity of the products was 4mPas regardless of the fermentation time. Chemical characterization indicates glucose contents of 68.21 and 94.01% in fermented potato for 24h and 21h respectively. The solubility index gives values of 70.3 ± 0.16 and 88.11 ± 0.23 for fermentation times of 21h and 24h respectively. Results of this work indicated that cooked sweet potatoes ferment for 21h was a promising substrate for production of exopolysaccharides.

Thisresearch was conducted in April to May 2018, housed in the Raman Farm enclosure in Puosu JayaVillage, Konda District, Konawe Selatan District. The material used in this study was 64 weeks oldbroiler chickens, with 64 feed ingredients used as the concentrate, corn, bean, sweet potato flour. Theequipment used is a scale, a colony cage made of wire-lined wood and measuring 4m x 2m, which isdivided into 16 plots and the size of each 1m x 0.5m, each story is equipped with a place to eat anddrink, 40-watt incandescent balloons and other equipment such as scales, ovens, sample grinders,basins, plastics, and gutters. This study was designed using a complete randomized design with fourtreatments and four replications, where four treatments consisted of P0 basic ration (Control), P1:basic ration containing 4% red sweet potato flour, P2: elemental percentage containing 6% red sweetpotato flour, and P3: basic ration contains 8% red sweet potato flour. The variables observed in thisstudy were cutting weight, carcass percentage, and abdominal fat of broiler chickens. The results ofthe analysis of variance showed that the administration of red sweet potato flour had no significanteffect (P> 0.05) on the percentage of carcasses and abdominal fat of broiler chickens. Broiler chickenaged five weeks. It was concluded that the provision of different red sweet potato flour in feed did notsignificantly affect slaughter weight, carcass weight, and abdominal fat percentage of broilerchickens. There is a tendency for broilers fed with red sweet potato flour to have heavier cut weights,a more significant portion of carcasses and an increase in the level of red yam, and a decrease inabdominal fat content and the addition of red yam levels in the feed.

Natural sources of antioxidants are derived from fruits, vegetables and wine, whilst artificial supplements are from teas and spices. Sweet potato (Ipomoea batatas) is an excellent natural source of vitamins and minerals, and likely a great source of antioxidant. The objective of this study  is to analyze the antioxidant activity of orange sweet potato (Vitato) and  purple sweet potato (All purple), prepared as heat dry and  moist heat for 30 minutes at 100oC. All the samples were obtained from Pasir Puteh and MARDI Telong, Bachok, Kelantan, respectively. Both samples were soaked into methanol to obtain the crude extract prior to analyzing for antioxidant activity by using 2, 2-diphenyl-1-picryl hydrazyl (DPPH). IC50 values of dry heat and moist heat Vitato were 0.40mg/L and 0.20mg/L while dry heat and moist heat, All purple were 0.32mg/L and 0.19mg/L, respectively. Both moist heat samples enjoyed higher scavenging activities compared to dry heat samples. However, the All purple sample of moist heat is the most superior one. Significant difference of IC50values between dry heat and moist heat sample differ significantly. Thus, this study clearly demonstrated that moist heat sweet potato exhibited  excellent increase in antioxidant activity.

Sweet potato (Ipomoea batatas) is a food crop that supplies energy, minerals and vitamins C and B. Some cultivars are very rich in carotenoids (pro-vitamin A). In this study were evaluated and compared the total carotenoids content of two cultivars and the losses on the dehydrated extruded sweet potato flour. Samples from organic and conventional crops were analyzed, in the form of fresh and dehydrated extruded samples. Total carotenoids content of the fresh product, expressed on wet basis, was of 437 µg 100 g-1 for the cream cultivar and 10,12 µg 100 g-1 for the orange cultivar. After dehydration, losses of total carotenoids were of 41% and 38%, respectively. The fresh orange cultivar presented high total carotenoids content in comparison to the cream cultivar. The extruded orange sweet potato flour showed the lowest losses in total carotenoids. Therefore, the processed flour of orange sweet potato could be used to obtain pre-gelatinized extruded flour with high total carotenoids content.
