In last decades, New Product Development (NPD) process has become crucial for the company success. Many efforts have been paid in order to identify methods and tools able to improve NPD, but successful models are still missing or not easily followed. Companies find difficult to implement comprehensive models for improving their NPD process, and often they aren’t even aware on how they actually ...

With the changing of lifestyles globally, demand for ready-to-eat (RTE) foods has increased. However, most these RTE have been associated with intermediate (55-70) to high glycaemic index (GI) (>70) linked incidences type 2 diabetes. Nyandarua County in Kenya is a major producer and consumer potato second highest diabetes prevalence (10.8%). Therefore, there need investigate whether relationshi...

Three different drying methods, microwave spouted bed drying (MSBD), microwave-vacuum drying (MVD), and hot air drying (AD), were used to dry diced sweet potato. The drying characteristics and product quality are discussed in terms of the drying kinetics, rehydration ratio, expansion ratio, breaking force (crispness), product colour, and retention of β-Carotene. As expected the drying rates in ...

Performance measurement is a key issue when a company is designing new strategies to improve resource allocation. This paper offers a new methodology inspired by classic importance–performance analysis (IPA) that provides a global index of importance versus performance for firms. This index compares two rankings of the same set of features regarding importance and performance, taking into accou...

Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in beta‐carotene and adapted to local growing environments have the potential to significantly reduce the prevalence of vitamin A deficiency. One such example is the orange sweet potato (OSP). Because of its distinctive orange color, which is in contrast to th...

The potato processing industry is among the biggest water-consuming industries, using an average of 17 L water per 1 kg processed product. Taking into account that fourth-most-important non-cereal food crop with a global production 376 million tons year, this branch large wastewater producer. Potato-processing highly loaded and thus difficult to treat through conventional methods, especially wh...

Reducing the use of pesticides by early visual detection of diseases in precision agriculture is important. Because of the color similarity between potato-plant diseases, narrow band hyper-spectral imaging is required. Payload constraints on unmanned aerial vehicles require reduction of spectral bands. Therefore, we present a methodology for per-patch classification combined with hyper-spectral...

Potato has become one of the primary cash crops in the arid region of the Loess Plateau. However, what and how cereal crops to rotate with potato is better for the farmer’s income and environment is unclear now. 11 potato based rotation systems were simulated in Yulin, using EPIC model based on local information. Results showed 1) Though mean potato yield decreased from 6.84 to 5.38 t/hm, the m...
