Kuningan Regency is the area that has potential in agriculture. One of the leading commodities in Kuningan Regency is sweet potato (Ipomea batatas L). Sweet potato cultivation continues to be developed, even in Cilimus District, it is known as one of the productive production centers in the West Java region which provides sweet potato supplies to several areas to supply sweet potato needs in the West Java region. The problems are faced by farmers today including the increasingly erratic price of sweet potatoes, lack of market opportunities, product diversification, and mastery of cultivation technology. This service activity was carried out in Cilimus Village, Cilimus District, Kuningan Regency with partners of sweet potato farmers. The purpose of this assistance is to provide supply chain assistance for sweet potato marketing so that farmers are able to continuously market sweet potatoes above the production price. Mentoring activities were started from identification of sweet potato problems at the farmer level, identification of production and identification of markets. The using of method is interactive discussion and market mapping conducted together with farmers. Focus Group Discussion (FGD) was used to confirm the cultivation system, production, and marketing system of sweet potato. The result of this activity is that farmers know the marketing potential of sweet potatoes other than middlemen and the quality criteria of sweet potatoes according to industry demand. In addition, farmers also use sweet potatoes as animal feed.

Cooking induces numerous phytochemical changes in food. This study is aimed at determining the amount of phytochemicals present in raw and cooked sweet potato, Irish potato and yellow yam. The amount of tannin, alkaloids, saponin, flavonoids and phenol were determined in raw and cooked samples of each food crop. The result showed that tannin, alkaloids, saponin, flavonoids, phenol contents was high in Irish potato and sweet potato but was far much present in Irish potato, while it was seen in minute quantity in yellow yam. The values obtained for each phytochemicals in each food sample raw and cooked respectively, in mg/100g were; Yellow yam: Tannins (0.10 and Nil), Alkaloids (2.00 and 0.51), Flavonoids (1.18 and 0.87), Saponins (2.00 and 1.02) and Phenols (0.72 and 0.10). Sweet potato: Tannins (0.32 and 0.28), Alkaloids (2.17 and 0.62), Saponins (2.10 and1.58), Flavonoids (1.28 and 0.97) and Phenols (1.42 and 0.72). Irish potato: Tannins (0.55 and 0.49), Alkaloids (2.17 and 0.81), Saponins (4.00 and 2.13), Flavonoids (5.00 and 2.91) and Phenols (2.00 and 0.91). The % loss of phytochemicals after cooking were; Yellow yam: Tannins (Nil), Alkaloids (74.5), Saponins (49.0), Flavonoids (26.3) and Phenols (86.1). Sweet potato: Tannins (12.5), Alkaloids (71.4), Saponins (24.8), Flavonoids (24.2) and Phenols (49.3). Irish potato: Tannins (10.0), Alkaloids (62.7), Saponins (46.8), Flavonoids (41.8) and Phenols (54.5). These results indicate that boiling of the samples seems to reduce their phytochemical contents as the raw samples showed higher amounts of the phytochemicals. The results also revealed that Tannins are more stable to heat across the 3 food samples, followed by Flavonoids, Saponins, Phenols and Alkaloids. The loss in some of the phytochemicals after cooking did not significantly affect the nutritional quality of the food samples.

Leaves of I. batatas have been implicated in both the hematopoietic process and in the management of hyperlipidemia in man. The current study evaluated the hematopoietic potentials and the lipid profile stabilizing potential of ethanol leaf extract of I. batatas in albino rats. The study was carried out at the Department of Biochemistry and Molecular Biology of the Nasarawa State University, Keffi, between March 2019 and October 2019. The determination of the phytochemical composition of the leaves was carried out. Sixteen albino rats weighing between 100-150g were randomly distributed into 4 groups of 4 rats each. Animals in group 1 served as the control while animals in groups 2, 3, and 4 served as the test groups and were administered 200, 300 and 400g/kg body weight respectively of ethanol leaf extract of I batata for fourteen days following standard procedures. The extract contained terpenoids in high amount, flavonoids and alkaloids in moderate amounts, while glycosides, phenolic, and steroids were present in low amounts. WBC counts increased significantly across the test groups compared to the control. PLT decreased significantly (P = 0.05) in all the test groups when compared to the control group. MCV increased significantly (P = 0.05) in all the test groups when compared to the control group. MCH increased significantly (P = 0.05) in group 2 but decreased significantly in groups 3 and 4 when compared to the control group. The lipid profile parameters; triglycerides (TAG), total cholesterol (TC), low density lipoprotein (LDL-C) showed no significant changes but HDL-C decreased significantly in group 4 compared to the control. The outcome of this study revealed that the ethanol leaves extract of I. batatas may possess a hematopoietic effect but may not be effective in the management of hyperlipidemia.

Various analytical approaches for determining β-carotene in vegetable crops and commercial dosage forms have been documented. However, neither the qualitative nor quantitative environmental safety and greener aspects of the literature analytical methodologies of β-carotene analysis have been assessed. As a result, the goal of this research is to develop and validate a reversed-phase “high-performance thin-layer chromatography (HPTLC)” approach for determining β-carotene in traditional (TE) and ultrasound-assisted (UBE) extracts of different fractions of Daucus carota (L.), Ipomea batatas (L.), and commercial formulation. The greener mobile phase for β-carotene analysis was a ternary mixture of ethanol, cyclohexane, and ammonia (95:2.5:2.5, v v v−1). The detection of β-carotene was done at a wavelength of 459 nm. In the 25–1000 ng band−1 range, the greener reversed-phase HPTLC approach was linear. Other validation factors for β-carotene analysis, including as accuracy, precision, robustness, and sensitivity, were likewise dependable. The contents of β-carotene were found to be maximum in hexane: acetone (50:50%) fractions of TE and UBE of D. carota and I. batatas compared to their acetone and hexane fractions. The amount of β-carotene in hexane: acetone (50:50%) portions of TE of D. carota, I. batatas and commercial formulation A was estimated to be 10.32, 3.73, and 6.73 percent w w−1, respectively. However, the amount of β-carotene in hexane: acetone (50:50%) portions of UBE of D. carota, I. batatas and commercial formulation A was estimated to be 11.03, 4.43, and 6.89 percent w w−1, respectively. The greenness scale for the proposed HPTLC strategy was calculated as 0.81 using the “analytical GREEnness (AGREE)” method, indicating that the proposed HPTLC methodology has good greenness. The UBE approach for extracting β-carotene outperformed the TE procedure. These results indicated that the greener reversed-phase HPTLC approach can be utilized for the determination of β-carotene in different vegetable crops, plant-based phytopharmaceuticals, and commercial products. In addition, this approach is also safe and sustainable due to the utilization of a greener mobile phase compared to the toxic mobile phases utilized in literature analytical approaches of β-carotene estimation.

Abstract Sweetpotato (Ipomea batatas), as a well-known plant and widely cultivated by farmers in South Sulawesi, if it is intercropped with satoimo taro (Colocasia esculenta (L.) Schott var. Antiquorum) as a staple crop should be suspected of being able to be a ‘safety’ crop when there is a failure in taro plant—due to the relatively new and un-well-known plant. The study was aimed to know the productivity and economic value of sweet potato planted as an intercropped on the staple crop satoimo taro plantation with several levels of compost. The study used a randomized complete block design with four levels of manure compost, namely 400 grams, 800 grams, and 1200 grams per staple plant, which put into and mixed evenly in the plant hole, and 1200 grams per staple plant which mixed evenly in the beds, and three blocks. Sweet potatoes were planted between staple plants satoimo that arranged 20 plants in a bed of 500 cm x 110 cm in two rows. The parameters observed were yields of tuber per plant, size of tuber, number of tubers, and dry weight of tops. The results showed that there is no level of compost affected significantly. However, both of the levels of 1200 grams of compost which is filled into the plant hole, and 1200 grams of compost mixed in the beds tended to be higher than the others in tuber productivity. By economic valuations, the RC-ratio and RC-ratio indicated that planting intercropped sweet potato are beneficially in all levels and increased after the levels of compost. Cultivating sweet potato intercropped in the two kinds application of 1200 grams levels in the taro plantation is more recommended.

The main aim of the study was to prepare the edible films based on carrageenan/chitosan and incorporate them into the following matrices: the natural extracts of Clitoria ternatea, Brassica oleracea, and Ipomea batatas. The films were characterized by TPC (total polyphenols content), antioxidant activity, and textural properties. Experimentally produced films were added in the packaging of freshly cut apple pieces, and the apple pieces were dipped into the films produced from carrageenan and chitosan. The appearance of the samples was monitored, as were antioxidant activity and total polyphenol content. The intelligent properties of films were evaluated too. The polymer type used for the preparation had the highest impact on the prepared films, and CHLCZ (red cabbage extract—Brassica oleracea) featured the best antioxidant activity. The intelligent properties were slightly confirmed in samples with the addition of red cabbage. The main finding was that the coating of fresh-cut apples emphasized the possibility to use a carrageenan matrix with the addition of extracts. The samples immersed in this coating type showed higher antioxidant activity as well as a superior color when compared to that of chitosan coated apple samples.

The aim of this study was to determine the potential of Andean Crop Flours (ACF) to develop muffins suitable for people with celiac disease or gluten intolerance, as these flours do not contain gluten in their composition. The physico-chemical, rheological, microbiological and sensory properties of muffins from different blends of the following ACF were evaluated: camote (Ipomea batatas), oca (Oxalis tuberosa), achira (Canna indica) and mashua (Tropaeolum tuberosum), formulated with sucrose or sucralose. Wheat muffins with sucrose were used for control purposes. The effect of 5-day storage on color, texture and microbiology was also studied. The use of ACF sharply increased the amount of total dietary fiber, while fat and protein contents were slightly lower with respect to the control. Regarding color, formulations with ACF resulted in darker products, showing an important decrease in L* and b* values while a* increased in all ACF formulations. According to their rheological properties, all doughs showed an unstructured and viscous behavior, and the mixture of camote, achira and mashua with sugar was very similar to wheat muffin. On textural parameters, there was an increasing (p < 0.0) effect on firmness and chewiness noticeable on day 5 in all samples. The resultant muffins were considered safe products due to low counts of total microorganisms, molds and yeasts and the absence of Enterobacteria and Staphylococcus aureus during storage. Muffins with ACF showed good overall acceptability, especially muffins containing sucralose, which obtained the highest score. This study showed that ACF could be used as an alternative raw material in the preparation of gluten-free muffins with good nutritional quality, thus providing a useful alternative for underused crops.
