This paper analyzes how a newly developed food product (potagurt) with nutritional and health benefits can be promoted in Ghana. We employ the hedonic modeling and contingent valuation methods to estimate monetary values attached to the product’s attributes using 400 consumers in the Ashanti, Eastern, and Greater Accra regions of Ghana. The findings reveal that consumers have positive perceptions on the health and nutritional benefits of the product. Buyers place a higher value on potagurt relative to normal yogurt. The high value attached to potagurt is mainly linked to the health, nutritional, food safety, and quality attributes of the product, as well as perception. Consumers’ socioeconomic factors such as income, educational, and awareness levels also play a significant role in explaining their choice of the product. The practical implication is that the development and promotion of potagurt could stimulate sustainable economic development through better consumer health and improvement in the livelihoods of many players in the sweet potato value chain, especially the producers of potagurt and sweet potato farmers. We conclude that the promotion of the innovative food product could contribute to sustainable production and consumption of sweet potatoes.

A thorough analysis of farmers’ purchasing power is very important because of agricultural products’ unique characteristics that likely position farmers more vulnerably. In this respect, we seek to anayze farmers’ purchasing power and market conditions of an agricultural product (sweet potatoes) by using the value chain and SCP (structure, conduct, performance) analyses. This study is administered in Bergas Sub-district, Semarang Regency that exhibit high potentials of sweet potato products. Our research sample are farmers, marketing institutions, and governments that are selected with the purposive sampling and snowball sampling methods. The results show that sweet potatoes marketing in this sub-district has four marketing channels and the market structure is oligopoly. The concentration ratio (CR4) of 0.52 indicates that the market has weak concentration with the Minimum Efficiency Scale (MES) score of 65%, implying that new competitors are obstructed to enter the market. Further, the fourth market channel has efficient marketing system performance with the marketing margin of Rp 1,500/ kg and farmers’ market share of 57.14%. Overall, our results suggest that farmers have to select short marketing chains and sell their products to final consumers.

Abstract This study analyzes the existing value chain of sweet potatoes in the Partido District of Camarines Sur, the Philippines. A combination of surveys and participant observation was utilized in the study. Four sociological perspectives were used in the interpretation and analysis of the data, such as new economic sociology, symbolic interactionism, role theory, and exchange network theory. Six components of the value chain were evaluated, such as (a) agents, roles, and links; (b) inputs, outputs and activities that generate transformation; (c) value addition and value allocation; (d) final products or a group of final products; (e) power relations and governance mechanisms; and (f) problems and opportunities shared by all agents. The study found four major links involving five actors – farmers/producers, middlemen or wholesalers, retailers, processors, and end consumers. Analysis of the sweet potato value chain shows that sweet potato production has great potential to improve the well-being of participants. Sweet potato production gave farmers an 81% net profit margin and contributed to 39% of their livelihood. However, there remain general production and utilization challenges and post-harvest and by-product processing issues. The study established the significance of embeddedness and the wider social structure for the sweet potato agribusiness and provided policy inputs for the development of the sweet potato value chain in the district.

Background: The Integrating Orange Project promotes production and consumption of orange-fleshed sweet potato (OFSP) to address vitamin A deficiency among rural populations of Zambia since 2011. Objective: This study assessed household production and consumption of OFSP and identified factors associated with consumption thereof in Integrating Orange Project areas in Chipata district, Zambia. Methods: Respondents of 295 randomly selected households were interviewed using a structured questionnaire during the sweet potato harvest season. Associations between OFSP consumption and household factors were assessed using χ2 tests. Results: Frequency of OFSP consumption was categorized as ≥4 days during the last 7 days (30.2%), 1 to 3 days during the last 7 days (49.5%), eats OFSP but not during the last 7 days (7.1%), and never (13.2%). In total, 60.3% of households planted OFSP, and 40.0% bought OFSP, mostly from farmers within the community. Orange-fleshed sweet potato consumption was associated with the presence of children aged less than 5 years in the household ( P = .018), production of OFSP ( P < .001), purchasing of OFSP ( P < .001), and respondent having knowledge on health benefits of OFSP ( P = .014). Age and sex of the household head and household size had no association with OFSP consumption ( P > .05). Conclusion: A high percentage of households consumed OFSP during the harvesting season in Integrating Orange Project areas. Programs promoting OFSP consumption should thus focus on OFSP production and sensitizing households on nutritional benefits of OFSP and target households with children aged less than 5 years as entry point.

Abstract Objectives The project tested the hypothesis that baked sweet potato chips will retain nutrients and can be produced with lower fat than commercially prepared fried chips. Sweet potato is a staple food that is a good source of dietary fiber, copper, manganese, antioxidants, vitamins C, A, B6, and E and is low in calories and fat. Orange-fleshed sweet potato is a good source of beta-carotene, a vitamin A precursor. Due to its nutritional benefits, demand is increasing and a growing market has created a variety of sweet potato products. Beta-carotene is a heat, light, oxygen labile molecule that can be used as a marker for nutrient degradation when sweet potato is heat-processed. Most commercial sweet potato chips are fried in oil, which helps to lower the glycemic index, but may also lower the nutrient density in the higher calorie product. Our goal is to test newer methods for making baked sweet potato chips with commercially available air-fryers and compare the products to chips baked with conventional and convection ovens. Methods Sweet potato chips were prepared from fresh commercially purchased Covington sweet potatoes cut into 3 mm slices with a semi-automatic food slicer. The slices were lightly sprayed with a vegetable oil aerosol and cooked in air fryers for 15 min at 400°F (204°C), in convection ovens for 15 minutes at 415°F (213°C), and in conventional oven at 400°F for 20 minutes. Crispness was determined by a 3-point bending test. Results The fresh sweet potato contained 22% DM and the chips averaged 70% DM after cooking in air fryers, 60% DM after cooking in convection ovens, and 64% DM after cooking in conventional oven. Beta-carotene content was 24.2 ± 4.5 mg/100 g DM in the fresh sweet potato, and decreased to an average 7.6 ± 1.9 mg/100 g DM in the air-fried chips, 14.1 ± 4.1 mg/100 g DM in the chips cooked in the convection ovens, and 6 ± 1.7 mg/100 g DM in the conventional oven. The rheological test found the chips with greater beta-carotene retention from the convection oven to be less crisp and have less charring than chips made in the air fryer or in the conventional oven. Conclusions Air frying technology shows promise for making low-fat sweet potato chips but nutrient degradation may still be an issue that needs further research.

В 2017–2019 годах изучены сортообразцы сладкого картофеля на староорошаемых лугово-сероземных почвах Зарафшанской долины. Цель исследований – комплексная оценка сортообразцов батата в условиях Зарафшанской долины по скороспелости, росту, развитию, интенсивному размножению, формированию урожая, компактности клубней в гнезде, продуктивности, урожайности и лежкости клубней и выделение из них перспективных, а также разработка приемов агротехнологии получения высоких урожаев для данных условий. Почвы опытного участка характеризуются благоприятными агрофизическими и водными свойствами и низким содержанием гумуса, нитратного азота, подвижного фосфора и содержанием обменного калия от низкого до среднего. Сравнивали 18 сортообразцов батата. Выделенные сортообразцы изучали при ширине междурядий 70 и 90 см со схемой 70×25 и 90×20 см по 1, 2 и 3 растения в гнезде. Для получения рассады сортообразцов батата брали по 40 клубней и высаживали 20–22 февраля в пленочной теплице при температуре 15–18 °C, заделывая их на глубину 3–5 см. Влажность почвы поддерживали на уровне 65–70%. Через 7–10 дней после высадки почки начинают прорастать, а через 43–48 дней формируется рассада высотой 12–15 см, готовая для высадки в поле. Высадка рассады, как и других рассадных культур (томата, перца, баклажана) – по схеме 70×20–25 см во второй-третьей декаде апреля. Уход включал в себя междурядную обработку (культивация), прополку, борьбу с сорняками, подкормку, поливы. Уборка урожая – в конце сентября-начале октября с помощью картофелекопателя. В результате исследований выделились сорта по скороспелости, дружности формирования ростков, ускоренному размножению, продуктивности, компактности клубней в гнезде и с высоким товарным урожаем – Сочакинур, Хар-Бей и Япон. Возделывание этих сортообразцов по схеме 70×25 и 90×20 см способствует получению товарного урожая высокого качества не менее 43–48 т/га. In 2017–2019, studies were conducted on the study of varieties of sweet potatoes on old-irrigated meadow-gray-earth soils of the Zarafshan valley. The purpose of the research is a comprehensive assessment of sweet potato varieties in the conditions of the Zarafshan valley in terms of early maturity, growth, development, intensive reproduction, yield formation, compactness of tubers in the nest, productivity, yield and keeping quality of tubers and the selection of promising ones, as well as the development of methods of agricultural technology for obtaining high yields for given conditions. The soil is characterized by favorable agrophysical and water properties and low content of humus, nitrate nitrogen, mobile phosphorus and a low-average content of exchange potassium. Eighteen sweet potato varieties were compared. The selected variety samples were studied with a row spacing of 70 and 90 cm with a scheme of 70×25 and 90×20 cm for 1, 2 and 3 seedlings in the nest. To obtain seedlings of sweet potato varieties, 40 tubers were taken and planted on February 20–22 in a film greenhouse at a temperature of 15–18 °C, seeding to a depth of 3–5 cm, the soil moisture was maintained at 65–70%. 7–10 days after planting, the buds began to germinate, and after 43–48 days, seedlings were formed with a height of 12–15 cm, which is ready for planting in the field. Planting seedlings in the field is carried out, as well as other seedlings (tomato, pepper, eggplant) according to the scheme 70x20–25 cm in the second or third decade of April. Growing includes inter-row processing (cultivation), weeding, weed control, top dressing, watering. Harvesting in late September, early October with a potato digger. As a result of the research, varieties were identified in terms of early maturity, sprout formation, accelerated reproduction, productivity, compactness of tubers in the nest and ensuring a high marketable yield – Sochakinur, Xar-Bey, and Japon. The cultivation of these varieties according to the scheme 70×25 and 90×20 cm contributes to the production of a commodity crop at 43–48 t/ha with good qualities.

Sustainable meal choices in the out-of-home catering market are essential to attaining the Sustainable Development Goals. This study investigated consumers’ acceptance of different features that help service providers to work more sustainably. For this purpose, data of a choice experiment and a supporting online questionnaire were analyzed using latent class analysis (LCA) and the data of n = 373 employees. Examined attributes in the choice experiment were menu variety, menu type, ordering system, ingredients and price. LCA led to four consumer segments: variety seekers (27.6%), spontaneous decisionmakers—vegetarian (25.7%), spontaneous decisionmakers—meat (24.1%) and vegetarians/vegans (22.6%). Results showed that consumers in all four segments expected to have the choice between different menus in company canteens. Moreover, they preferred spontaneous choice to preordering. Both preferences hamper sustainable production and consumption in the catering sector.
