... Although existing sweet potato transplanters require automatic seedling feeding instead of manual seedling feeding, this causes seedling leakage and low efficiency. In this work, a control system for automatic seedling feeding of sweet potatoes was designed based on a pre-treatment seedling belt. The system uses STM32 as the main controller and obtains the running speed of the machine through the ...
... Direct planting (i.e. the planting of seed roots) in sweet potato results in the formation of two root types – ‘mother’ and ‘daughter’ roots. High and stable daughter root yields are necessary to improve the acceptance of direct planting cultivation because mother roots have no commercial value. To establish a basis for the effective breeding, the root traits of 28 sweet potato genotypes cultivate ...

Abstract:
... Healthy and convenient foods have drawn consumers' attention and represent an opportunity for the food industry. This study is about the production of sliced sweet potato snacks by microwave vacuum drying (MWVD) in a rotary container with temperature control by power modulation. The average temperature of samples' surfaces was measured with an infrared sensor and controlled at 60 °C by a PID contr ...

... Transcription factors IbMYB1-1 had been identified involving anthocyanins biosynthesis in purple-flesh sweet potato. However, the upstream transcription factors on PIbMYB1-1 involed in anthocyanin biosynthesis had rarely been reported. In this study, the upstream transcription factors on PIbMYB1-1 were screened by yeast one-hybrid screening in purple-fleshed sweet potato storage roots. The results ...

Abstract:
... Characterization of the airflow across food items involves identification of their viscous and inertial resistances. This paper presents an extensive numerical and experimental study to determine the resistances of food items placed in an array. The experimental study used an array of sliced sweet potato with different initial slice diameters. The airflow resistance of the array was determined fro ...

Abstract:
... Ipomoea trifida, the closest relative of sweetpotato, does not generally form storage roots, but some lines develop thick roots similar to the storage roots of the sweetpotato. Revealing the molecular mechanism of thick root development in I. trifida would help us understand the evolution of storage roots in the sweetpotato. In this study, we conducted a mapping method for quantitative trait loci ...

Abstract:
... Simultaneous estimation of thermal properties can be challenging, especially when the parameters are temperature-dependent. Previous research has shown that by using a complementary experiment, temperature-dependent thermal conductivity can be estimated using a single experiment. The objective of this study was to optimize the complementary experiments that can facilitate the simultaneous estimati ...

... The health benefits of purple sweetpotato, which is used as an edible food in its natural state and in processed foods and as a natural color pigment, have been recognized. In Japan, sweetpotato has been economically produced in regions below 36°4ʹN latitude; however, cultivation areas are beginning to expand further north. The anthocyanin and polyphenolics in three purple sweetpotatoes cultivated ...

... A novel sensor based on bead-counting of purple sweet potato tapioca pearl for freshness monitoring of shrimp was proposed. The sensor was prepared from commercially available tapioca pearls with purple sweet potato as a natural colorant by using a similar procedure as to prepare “Thai Saku dessert”. A novel concept of using five tapioca pearls stacked in a pipette tip was proposed to observe the ...

Abstract:
... Sweetpotato is prone to disease caused by C. fimbriata without obvious lesions on the surface in the early period of infection. Therefore, it is necessary to explore the possibility of developing an efficient early disease detection method for sweetpotatoes that can be used before symptoms are observed. In this study, sweetpotatoes were inoculated with C. fimbriata and stored for different lengths ...

Abstract:
... Anthocyanins in sweetpotato (Ipomoea batatas L.) have attracted much attention in light of their multiple health benefits and excellent properties as processed foods. Although crossbreeding is an effective way to breed new cultivars of sweetpotato, there are few reports on how anthocyanin content and composition are passed on to F₁ hybrid generations by crossbreeding because of a complex genome an ...

... China is the world’s biggest producer of sweet potato (Ipomoea batatas (L). Lam.), and approximately 55% of the global supply is from China. Raised beds (RB) and raised beds mulched with plastic film (RBF) are the two main sweet potato cultivation systems now widely used in northern China. Planting placement of multiple nodes buried in shallow soil layers is additionally required for the sweet pot ...

Abstract:
... Sweetpotato is an important and nutritionally rich crop. Melatonin (MT) possesses great potential for promoting the postharvest preservation of vegetables and fruit. However, the function of MT in postharvest sweetpotato is rarely characterized. Here, the functional mechanism of exogenous MT was evaluated in fresh-cut tuberous root of sweetpotato. Experimental results revealed that MT treatment st ...

The purpose of this study is to investigate the effects of belt catalytic infrared drying (BCIRD), belt catalytic infrared blanching BCIRD (BCIRB-BCIRD), and hot water BCIRD (WB-BCIRD) on the structural and functional properties of sweet potato starch (SPS). The results revealed a decrease in the starch content of SPS by 5% after WB-BCIRD treatment. The starch granules subjected to BCIRD and BCIRB ...

... Honkaku shochu and awamori are traditional Japanese spirits. 2-Furanmethanethiol (2FM), a volatile thiol, was identified as a roast aroma compound in honkaku shochu and awamori. The detection threshold of 2FM in 25% (v/v) ethanol water solutions was determined as 1.6 ng/L. The odor activity values, calculated using the detection threshold suggested that 2FM affects the quality of honkaku shochu an ...

... Sweet potato extracts are reversible competitive trypsin inhibitors. Sweet potatoes are a good food source, but they contain trypsin inhibitors, which reduce the protein utilization rate in animals. This study analyzed the trypsin inhibitor activity of ten sweet potato varieties. Most of the sweet potatoes designated for animals exhibited high trypsin inhibitor activity. The trypsin activities of ...

... The drying of agricultural produce is an important food preservation measure. However, high energy requirements for drying, limited access to energy sources, small-medium scale farmers experience high post-harvest losses of their produce. Therefore, there is a need to develop and optimize low-cost food preservation technologies. In this study, eleven mathematical models were used to estimate the d ...

The most predominant type of resistance (R) genes contain nucleotide-binding sites and leucine-rich repeat (NBS-LRR) domains, characterization of which is helpful for plant resistance improvement. However, the NBS genes of Ipomoea trifida (H.B.K.) remain insufficient to date. In this study, a genome-wide analysis of the NBS-encoding gene in I. trifida (H.B.K.) was carried out. A total of 442 NBS e ...
