The changes of growth characteristics and antioxidant activity for selection of optimum germinated temperature on common bean (Phaseolus vulgaris L.). Common beans (IT100888, IT102849, and IT231267) were cultivated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days of germination. The range of whole length, hypocotyls length, thickness, abnormal germination and yield rate of sprouts was 7.27~27.62 cm, 3.10~18.86 cm, 1.80~2.27 mm, 5.54~18.34% and 205.95~ 618.71%, respectively. Antioxidant activities of common beans with germination temperature investigated. Common beans (IT100888, IT102849, and IT231267) germinated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days, and then extracted with 80% ethanol, and analyzed for total polyphenol content, DPPH and ABTS radical scavenging activity. Total polyphenol content increased from 474 mg GA eq/100 g sample for IT231267 to 1364 mg GA eq/g sample for $23^{\circ}C$ of germination. DPPH radical scavenging activity of IT102849 increased from 189mg Trolox eq./100 g sample ($20^{\circ}C$) to 1073mg Trolox eq./100 g sample ($23^{\circ}C$) also ABTS radical scavenging activity of IT234267 increased from 479 mg Trolox eq./100 g sample ($20^{\circ}C$) to 1134 mg AA eq/100 g ($23^{\circ}C$). These results suggest that germination temperature for increasing antioxidant activities may be $23^{\circ}C$.

The present study was carried out to investigate the effects of nanopowdered peanut sprout-added Caciocavallo cheese (NPCC) on the prevention and treatment of rheumatoid arthritis in DBA/IJ mice immunized with type II collagen. After the induction of arthritis, the mice were being divided into five groups: (1) normal, no immunization; (2) CIA, collagen-induced arthritis; (3) MTX, collagen-induced arthritis treated with methotrexate (0.3 mg/kg body weight); (4) CC, collagen-induced arthritis treated with Caciocavallo cheese (0.6 g/d); (5) NPCC, collagen-induced arthritis treated with nanopowdered peanut sprout-added Caciocavallo cheese (0.6 g/d). Nanopowdered peanut sprout was ranged from 300 to 350 nm, while regular powdered peanut sprouts were ranged from 50 to $150{\mu}m$. The NPCC group had considerable reductions of clinical scores and paw thicknesses at the end of experiment as compared to the CIA group. In the serum analysis, the TNF-${\alpha}$, IL-$1{\beta}$, IL-6 and $IgG_1$ levels in the NPCC group have decreased by 69.4, 75.9, 66.6, and 61.9%, respectively, when compared to the CIA group. The histological score and spleen index of the NPCC group were significantly lower than the CIA group. In conclusion, the feeding NPCC method could delay and/or prevent the rheumatoid arthritis in the collagen-induced arthritis mouse model. Based on this study, nanopowdered peanut sprouts could be applied to various functional cheeses.

This study was conducted to compare the physicochemical and sensory properties of yogurt containing nanopowdered peanut sprouts (NPPS) and powdered peanut sprouts (PPS) at different concentrations (0.05-0.20%, w/v) during storage at $4^{\circ}C$ for 16 d. The pH values of NPPS (0.05-0.20%, w/v)-added yogurt were lower than those of PPS-added yogurt. The antiradical scavenging activity and LAB counts were significantly higher in NPPS-added yogurt than in PPS-added yogurt during the storage period of 16 d (p<0.05). Higher concentrations (0.15, and 0.20%) NPPS-added yogurt showed greater antiradical scavenging activity. The LAB counts were ranged from $9.00{\times}10^8$ to $1.10{\times}10^9$ and $1.30{\times}10^9$ to $9.10{\times}10^8$ CFU/mL in 0.05% and 0.20% NPPS-added yogurts, respectively. In sensory testing, 0.05 and 0.10% NPPS-added yogurt showed similar results to the control in whey-off, grainy texture, and overall acceptability. Yellowness and astringent scores increased with increasing addition of NPPS or PPS to the yogurt irrespective of its storage times. Peanut and beany flavors were lower during the storage for 0.05 and 0.10% NPPS-added yogurt. Based on the data obtained from the present study, it was concluded that 0.05 and 0.10%, w/v of NPPS could be used to produce NPPS-added yogurt without significant adverse effects on the physicochemical and sensory properties, but with an enhanced functional value added to the yogurt.

A study was conducted to examine the physicochemical and sensory properties of milk supplemented with nanopowdered peanut sprouts (NPPS) at different concentrations (1, 3, 5, 7, and 9%, w/v) during the storage at $4^{\circ}C$ for 16 d. The size of NPPS ranged from 300-350 nm as observed by the particle size analyzer. The pH values of all samples ranged from 6.8 to 6.6 during the storage of 16 d. In color, the $L^*$ value of milk samples were not remarkably influenced by NPPS supplementation, whereas the $b^*$ and $a^*$ values significantly increased with the NPPS supplementation at all concentrations at 0 d storage, due to the original yellow color of NPPS powder (p<0.05). DPPH study revealed that higher antioxidant activity of milk supplement with higher concentrations of NPPS. TBARS value found to lower at the lower concentrations (1 and 3%, w/v) of NPPS supplementation. The sensory test revealed that the overall acceptability scores of NPPS supplemented milk samples (1 and 3%, w/v) were quite similar to control throughout the storage period of 16 d. Based on the data obtained from the present study, it was concluded that the concentrations (1 and 3%, w/v) of NPPS could be used to produce NPPS-supplemented milk without significant adverse effects on physicochemical and sensory properties, and enhance functional components from the supplementation.

Recently, as consumers' interest and importance in health care have significantly increased, they prefer natural and organic foods that do not use chemical pesticides. Since sprout vegetables effectively promote health and prevent diseases such as cancer and cardiovascular disease, the consumption of sprout vegetables, a highly functional and safe food, has been increased significantly. This study aimed to investigate the effect of light on the growth and bioactive compounds of seven different sprout vegetables. After sowing the seeds of various sprout vegetables (kale, Chinese kale, broccoli, red cabbage, alfalfa, red radish, and radish), the sprouts were cultivated under light conditions (20℃, RGB 6:1:3, 130 μmol·m^-2·s^-1, 12 hours photoperiod) and dark condition for 7 days. Sprouts samples were taken at 1-day intervals from 4 to 7 days after treatment. The fresh weight, dry weight, plant height, total phenol content, and antioxidant capacity were measured. Brassica species (kale, Chinese kale, broccoli, red cabbage) and Medicago species (alfalfa) had significantly higher fresh weight values under dark conditions, while the content of bioactive compounds was increased considerably under light conditions. In contrast, the fresh weight of Raphanus genus (red radish, radish) significantly increased under the light condition, but the antioxidant phenolic compounds were significantly higher under the dark state. A negative correlation was observed between the growth and secondary metabolites in various sprout vegetables. This study confirmed the effect of light and dark conditions on different sprout vegetables' growth and nutritional value and emphasizes the importance of harvest time in producing high-quality sprout vegetables.

Background: The ginseng ginsenosides, which have various physiological activities, are known to be more abundant in the leaves than in the roots, and the consumers' interest in ginseng sprout as a functional vegetable has been increasing. Methods and Results: The aim of this study was to investigate the effects of growth period on growth properties, active ingredients and rheology of ginseng sprouts cultivated in a non-heated greenhouse equipped with a shade net for 60 days, starting from the end of May to the middle of July. The chlorophyll content of the leaves decreased, but their length and width increased with increasing cultivation days. In particular, growth increased significantly until 40 days, but only slightly after 50 days. The stem length did not increase greatly from the 20 th to the 30 th day of cultivation, but increased significantly from the 30 th to the 40 th day, and then further increased gradually. The weight of the leaves, stems, and roots increased slightly, but not change significantly. After 40 days of cultivation, the total ginsenoside content increased by 1.07 times in the leaves and decreased by 0.80 times in the roots with increasing cultivation days. The leaf contents of ginsenosides $Rg_1$, Re, $Rb_1$, Rc, $F_3$ and $F_4$ increased with increasing cultivation days. The rheological properties of ginseng sprout showed the greatest influence on stem hardening with increasing cultivation days. Conclusions: Therefore, based on the growth characteristics, active ingredients and physical properties, 40 days after sowing was considered to be an appropriate harvesting time for ginseng sprouts.

As the rural population continues to decline and aging, the improvement of agricultural productivity is becoming more important. Early prediction of crop quality can play an important role in improving agricultural productivity and profitability. Although many researches have been conducted recently to classify diseases and predict crop yield using CNN based deep learning and transfer learning technology, there are few studies which predict postharvest crop quality early in the planting stage. In this study, a early quality prediction model is proposed for sprout ginseng, which is drawing attention as a healthy functional foods. For this end, we took pictures of ginseng seedlings in the planting stage and cultivated them through hydroponic cultivation. After harvest, quality data were labeled by classifying the quality of ginseng sprout. With this data, we build early quality prediction models using several pre-trained CNN models through transfer learning technology. And we compare the prediction performance such as learning period and accuracy between each model. The results show more than 80% prediction accuracy in all proposed models, especially ResNet152V2 based model shows the highest accuracy. Through this study, it is expected that it will be able to contribute to production and profitability by automating the existing seedling screening works, which primarily rely on manpower.
