“…The range of compositional levels across the varieties is comparable with earlier reports in Ghana (Adu-Kwarteng et al, 2014;Darko et al, 2021;Sugri et al, 2019). In the report of Darko et al (2021), the application of fertilizer did not influence chemical composition (ß-carotene, starch, protein, and zinc) and cooking quality (taste, texture, and consistency) traits of the sweetpotato.…”

Sweetpotato (Ipomoea batatas (L) Lam) is prioritized among crops that enhance food security and reduce malnutrition in Ghana. The production is expanding faster than other food crops owing to its superior nutrient composition. This study evaluates integrated approaches to increase on‐farm productivity, income, and utilization of sweetpotato. The first part evaluated the agronomic yield performance, financial return, and sensory quality of 10 varieties under different fertilizer treatments. The second part of activities assessed both storage root and leaf composition (i.e., total sugars, dry matter, protein, Fe, Zn, Ca, total phenolic, total monomeric anthocyanins, lutein, zeaxanthin, α‐tocopherol, β‐carotene, and total carotenoids). Third, storage stability characteristics were assessed (i.e., shelf life and the incidence of decay). Application of NPK of 40:40:70 at 300 kg ha−1 significantly (p < 0.001) increased storage root yield from 12.4 to 17.3 t ha−1, which represents a 32% increase in yield compared to farmers’ standard practice. The variety SARI‐JanLow (where SARI is Savanna Agricultural Research Institute) was outstanding for root yield (23.5 t ha−1) and β‐carotene content (20.8 Mg 100 g−1). SARI‐Tiemeh was consistently ranked among the three most preferred varieties by the sensory panel across the production hubs. At locations Nyankpala and Nikongo, the most responsive varieties to fertilizer application with regard to marketable storage root yield were SARI‐Tiemeh (108%) and PGA14351‐4 (79%), respectively. The varieties SARI‐Nyumengre (1.4%), SARI‐Nyoriberi‐gu (1.4%), and PGA14351‐4 (1.6%) were the least susceptible to sweetpotato weevil attack. Considering the benefit–cost ratio and a return on investments, the four most economically viable varieties appear to be SARI‐JanLow, SARI‐Suyolo, SARI‐Tiemeh, and SARI‐Nyoriberi‐gu.

“…Apple juice was extracted by crushing the apple wedges with a JP351 Midea juicer (Midea Group Co., ltd, Shanghai, China) and analyzed for soluble solid content and pH. The total soluble solids (TSS) were measured with a digital refractometer PAL-1 (ATAGO ltd., Tokyo, Japan) according to ( Sugri et al, 2019 ) and are expressed as %. All samples were measured using a pH meter FE28 (Mettler Toledo, Zurich, Switzerland).…”

Quality control is one of the important factors in maintaining the consistency of the quality of a product. The activity of controlling the quality of raw materials to ensure the quality of raw materials. Quality control starts from the receipt of raw materials until the time the raw materials will be used. Quality is used to determine the level of consumer acceptance of the product. The quality of a product is strongly influenced by the quality of the raw materials of the product. Therefore, it is necessary to have quality standards for raw materials that function as parameters and limits for an acceptable raw material which will then be processed into a product. Supervision was carried out visually with parameters of color, texture, shape, and size of white sweet potato which was carried out for 8 days. The analytical method used is the descriptive method, check sheet, and Pareto diagram. The results of this study will be compared with the quality standard of sweet potato according to SNI 01-4493-1998. Based on the results of the study, it is known that the sweet potato quality standards are set in PD. Surabraja Putra is classified based on weight, namely B (> 500 g), R (300-500 g) and TO (> 250 g) on the condition that the sweet potato is not deformed, rotten, hollow, moldy, and there are no foreign objects (soil, stems, leaves, and litter). The quality standard of sweet potato weight is set in PD. Surabraja Puta has complied with the weight quality of sweet potatoes according to SNI 01-4493-1998. However, the weight range used by PD. Surabraja Putra is larger than the weight range of sweet potatoes according to SNI. Varieties of local sweet potatoes used as raw material for chili sauce in PD. Surabraja Putra are Eski, Gaul, Asban, Melati, Manohara, and White Ase from Kuningan and Majalengka. The most common sweet potato defect found was the eski variety with a percentage of 39% and a weight of 496 kg.
