Consumption of biofortified foods such as sweet potatoes with high content of β-carotene may reduce deficiency of this micronutrient. The development of biofortified sweet potato chips expands the distribution and offers an alternative to the consumption of this product. The aim of this study was to evaluate the thermal blanching methods (steam and in boiling water) in β-carotene retention in the production of dehydrated biofortified sweet potato chips with air circulation at 65°C. The raw material, the chips blanched in steam and in boiling water had a content of β-carotene of 501.86 ± 53.65, 490.23 ± 30.00 and 473.91 ± 11.43 µg g-1 (d.b.) respectively. The retention of β-carotene for steam and boiling water blanching was 97.7 and 94.4% respectively. The blanching conditions followed by drying used in the processing to obtain sweet potato chips were adequate as they resulted in β-carotene high retention.

Sweet potatoes are a cultural plant for the people of the Pegunungan Tengah, Papua because every day people in this region are always use sweet potatoes. Pegunungan Tengah, Papua community knows sweet potatoes with the name hipere. The purpose of this service is to change the behavior patterns of farmers in the process of processing sweet potatoes that have never been processed into regional superior products in Pegunungan Tengah, Papua. The implementation of this activity through KKN-PPM is by providing socialization and training in making various flavors of sweet potato chips. The results of this community service are the people of Wamena District can make various kinds of flavored sweet potato chips food products, thus helping the community in creating added value of products and can increase family income.


Objectives: The study aimed to (1) develop a shelfstable and acceptable vacuum fried sweet potato chips, (2) establish process schedule to conduct material balance, (3) evaluate the sensory characteristics of the chips and (4) determine its nutrient composition. Methodology: Sweet potato (Ipomoea batatas) was utilized and vacuum fried. The production of the crispy sweet potato chips comprised of selecting quality and newly harvested sweet potato, washing the selected sweet potato with 50ppm chlorinated water peeling and slicing the sweet potato with 2mm thickness cooking the sliced sweet potato for 10minutes, freezing the cooked sweet potato overnight, vacuum frying the frozen sweet psotato, cooling the vacuum fried sweet potato to room temperature and weighing and packing on an 89µm thickness laminated stand – up pouch. Then, material balance was evaluated accounting to wastage and moisture loss. Finally, the quality of the product was tested through sensory evaluation. There were three mass treatments used: Treatment A with 1.0kg; Treatment B with 3.0kg; and, Treatment C with 50kg. Each treatment had three (3) replicates and were fried at 100°C. Findings: Vacuum fried sweet potatoes for The three treatments recorded average bubble end – points of 42.33 (A), 47.67(B), and 52.67 (C) minutes. This shows that the weight to be processed per batch is directly proportional with the bubble end-point as temperature and pressure were held constant. Applications: Sweet Potatoes can be developed as crispy chips utilizing vacuum fryer

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.

Most of the livelihoods of Sukodono Village’s people, Pujer District, Bondowoso Regency are farming; various kinds of agricultural products produced by the residents of Sukodono Village are white AC sweet potato. But, the yield of many white AC sweet potatoes which is not sold well causes decays and makes farmers give up. When I was a field supervisor of KKN Unmuh Jember, the KKN students and I promoted the Nafiah Posdaya which had once been formed. With the hope to overcome the problem of the white AC sweet potato farmers, namely by processing white AC sweet potato into chips and cupcakes manually. Because of the limited manual equipment, the white AC sweet potato used for the basic ingredients of chips and cupcakes is still in small quantities. Also, chips which are produced manually are not crunchy; contain lots of oil, long time production process and small amount of production. To overcome this, product innovation needs to be done by making white ac sweet potato chips with vacuum frying and spinner technology as well as making white ac sweet potato cupcakes with an electric mixer to mix dough and oven it. The problem is those partners do not have the knowledge, skills and capital to develop and be innovation product white ac sweet potato. There are four main activities in the Community Partnership Program dedication activities that are carried out by providing material training and practicing (1) implementing vacuum frying and spinner machines to make white AC sweet potato chips (2) packing with beautiful package (3) making cupcake with basic ingredients from white AC sweet potato (4) marketing model based on E-commerce Web-based Information Technology. The results of this training are crispy white AC sweet potato chips with a distinctive sweet potato taste because the slices are thicker than the other chips and delicious white ac sweet potato cupcake with attractive toping is a promising market opportunity. It is expected that the Community Partnership Program activities can improve the welfare of partners.

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.

Two relevant studies on food security are referred to in the article. Food insecurity from time to time threatens in Teso sub region which houses a viable Teso agricultural system. One study was done during 2001-2003 in Teso on sweet potato production with 650 persons participating and the second one was done in one disaster affected area of Bududa District nearby during 2012-2016 when 1,142 persons participated. Kiryandongo District where Bududa landslide survivors were resettled in Uganda was included in that study. Participatory methods such as focus group discussions, farm observations, in-depth interviews, and questionnaires were used. Both studies used qualitative and quantitative methods for data analysis. The sweet potato stands second after cassava as the crop for famine and disaster periods in Teso to meet the human right to adequate food to complement the well dried cereals & grain legumes that stored longer. Livestock especially was also one of the prime determinants of food security and income in Teso. Free from cyanides with a good content of affordable Vitamin A from orange fleshed varieties, sweet potatoes in Teso contributed about 61% to the yearly food per capita of the population thus a recommendable crop for sustainable food security and some income in Teso and beyond.
