This study aimed to identify the optimal storage and germination conditions for producing sprouts from immature bulbils of the Korean garlic cultivar ‘Hongsan’. It also evaluated the effects of LED light quality on sprout growth and compared the functional compound contents across different plant parts. Germination trials indicated that storing bulbils at 4°C for at least 64 days, followed by germination at 10-20°C, yielded the best results. Under mixed LED light treatments (Red:Blue:White), a red-dominant ratio of 4:1:0 significantly enhanced both shoot and root elongation, while germination in darkness resulted in the highest fresh and dry weights. Among the plant parts, sprouted bulbils had the highest alliin content (3,711 mg/100 g) and contained greater levels of fructose and glucose compared to cloves. Conversely, cloves had the highest fructan content, and leaves exhibited the highest total polyphenol content. These findings underscore the importance of combining proper storage and light quality for efficient sprout production from bulbils and highlight the potential of sprouted bulbils as functional food materials.

본 연구는 나물콩의 주요 권역별 파종시기 생육단계 소요일수와 기후요인 간의 관계 분석을 통한, 기후변화에 대응 최적의 파종시기 설정을 위한 과학적 근거를 알아보고자 수행하였다. 나물콩 주요 재배 품종인 풍산나물콩과 아람을 대상으로 중북부내륙지대(춘천), 중부평야지지대(수원), 호남평야지대(완주) 및 남부해안지대(순천) 4 지역에서 파종시기별(5월 하순, 6월 상순, 6월 중순, 6월 하순) 주요 생육단계 소요일수와 적산온도 변화를 구명하였다. 그 결과, 4 지역에서 풍산나물콩의 소요일수는 평균 130일(112일~147일)로 조사되었고, 아람은 평균 131일(112일∼149일)로 조사되었다. 적산온도는 두 품종 모두 평균 3,234℃로 같게 조사되었다. 각 지역에 따른 파종시기별 영양 및 생식 생장기, 총 재배기간 동안의 소요일수, 적산온도 변화는 모든 지역에서 파종시기가 늦어질수록 소요일수가 단축되고, 적산온도는 낮아지는 경향을 보였다. 파종시기에 따른 지역별 영양생장기의 소요일수 및 적산온도는 춘천보다 위도가 낮은 지역에서 낮아지는 경향으로 나타났다. 반면, 생식생장기에서는 춘천보다 위도가 낮은 지역에서 소요일수와 적산온도가 높아지는 경향으로 나타났다. 이상의 결과로, 풍산나물콩과 아람의 재배기간 동안의 고온(≧30℃) 노출은 개화기 및 종실비대기 지연으로 소요일수 변화에 영향을 미치는 것으로 사료된다.

Sprout products, such as broccoli, alfalfa, and cabbage, have positive health effects. Thus far, sprout foods have attracted attention owing to their good bioavailability. In particular, young broccoli sprouts exhibit anti-inflammatory, antioxidant, and anti-cancer effects. They contain 100 times more chemoprotective substances than adult broccoli. This study examined the anti-inflammatory effects of freeze-dried young sprout broccoli (FD-YB) in vitro using RAW264.7 macrophage cells. The FDYB powder antioxidant ability test showed that the radical-scavenging activity and superoxide dismutase enzyme activity increased in a dose-dependent manner. In addition, FD-YB was not cytotoxic to RAW264.7 cells, and nitric oxide production decreased after the FD-YB treatment of lipopolysaccharide-stimulated RAW264.7 cells in a dose-dependent manner. Furthermore, FD-YB significantly decreased the expression of inflammation-related proteins (Cyclooxygenase-2, Inducible nitric oxide synthase, and Prostaglandin E Synthase 2) and cytokines (Tumor necrosis factor- and Interleukin-6). In conclusion, FD-YB can be a potential nutraceutical for preventing and regulating excessive immune responses during inflammation.

Background: Brassica oleracea var. italica (broccoli), a rich source of antioxidants, can prevent various diseases and improve human health. In this study, we investigated the antioxidative effects of broccoli sprout extract on oxidative stress induced by lipopolysaccharide and cisplatin in cell and organ tissue models. Methods: Antioxidative effect of BSE was evaluated using DPPH and ABTS in RAW 364.7 cells, and effects of BSE on testes were investigated using Cisplatin-induced testicular damage model with an in vitro organ culture system. Results: The DPPH assay showed that the antioxidant activity of the alcoholic broccoli sprout extract was higher than that of the water extract. Additionally, the expression levels of antioxidation-related genes, Nrf2 , Gsr , HO-1, and catalase , were significantly increased in broccoli sprout extract-treated RAW 264.7 cells, and the extract suppressed lipopolysaccharide-induced mitochondrial dysfunction. Based on the results in the RAW 264.7 cell culture, the antioxidative effects of the extracts were investigated in a mouse testis fragment culture. The expression of Nrf2 , HO-1 , and Ddx4 was clearly decreased in cisplatin-treated mouse testis fragments and not in both broccoli sprout extract- and cisplatin-treated mouse testis fragments. In addition, the oxidative marker O-HdG was strongly detected in cisplatin-treated mouse testis fragments, and these signals were reduced by broccoli sprout extract treatment. Conclusions: The results of this study show that broccoli sprout extracts could serve as potential nutraceutical agents as they possess antioxidant effects in the testes.

This research investigated the immunoenhancing effect through the intracellular MAPKs and NF-B signaling pathways in macrophages activated by crude polysaccharides (YBP) of barley sprouts. YBP extracted from barley sprouts is composed of xylose (25.8%), arabinose (24.1%), galactose (23.4%), and galacturonic acid (11.7%). YBP did not affect the cytotoxicity and showed superior secretion of nitric oxide (NO), interleukin (IL)-6, and tumor necrosis factor (TNF)- by RAW264.7 cells. Also, YBP dose dependently increased IL-6, TNF-, and inducible nitric oxide synthase (iNOS) mRNA gene expression. In the western blot, YBP strongly induced the phosphorylation of the p38, JNK, ERK, and IB pathways in RAW 264.7 cells. In the anti-pattern recognition receptor (anti-PRRs) assay, the effect of YBP on NO secretion strongly decreased toll-like receptor (TLR) 4 and Dectin1 antibodies, whereas IL-6 and TNF- secretion by YBP mainly decreased SR and CD14. Therefore, we concluded that YBPinduced NO, IL-6, and TNF- were secreted via the MAPKs, while NF-B pathways through TLR4, Dectin1, SR, and CD14 receptors existed in a macrophage surface and were involved in the immunoenhancing effect.

In this study, the growth characteristics of Lentinula edodes were confirmed by bean sprout waste(BW) as an alternative raw material for rice bran. The mycelium growth of Sanjo701, a major cultivation variety of L. edodes, was compared between a medium mixed with 8:2(v/v) of oak sawdust and a medium mixed with BW 50% and BW 100%. The mycelium growth in BW 50% was 13.5 cm. Compared to the control, BW 50% increased the diameter of the pileus by 1.6 cm. Additionally, the length of the pileus decreased by 0.4 cm when comparing the growth of the fruit body. In contrast, at BW 50%, the diameter of the pileus decreased by 9.6 cm and the length of the stipe decreased by 1.4 cm. According to analysis of the constituent amino acids, BW 50% showed a lower overall nutritional content than the control, whereas BW 100% had a lower amino acid content than the control. However, glutamic acid and aspartic acid, which are flavor-enhancing ingredients, were observed at levels of 3.954 mg/g and 1.436 mg/g, respectively, in BW 100%. Therefore, if bean sprout by-products are efficiently processed and utilized, it is believed that they will be beneficial to farmers as a substitute for rice bran and reduce the cost of manufacturing substrate

Brassica oleracea var. italica (broccoli) is a type of cabbage that contains vitamins, minerals, and phytochemicals. Consequently, it is used as a potential nutraceutical source for improving human health by reducing oxidative stress and inflammatory responses. Here, the effects of broccoli sprout extract (BSE) on the inflammatory response were investigated through lipopolysaccharide (LPS)- induced inflammatory mouse models. First, we found that the BSE obviously reduce NO production in RAW 264.7 cells in response to LPS stimulation in in vitro study. Pretreatment with BSE administration improved sperm motility and testicular cell survivability in LPS-induced endotoxemic mice. Additionally, BSE treatment decreased the levels of the pro-inflammatory cytokines TNF-a, IL-1β, and IL-6, and COX-2 in testis of LPS-induced endotoxemic mice models. In conclusion, BSE could be a potential nutraceutical for preventing the excessive immune related infertility.

This study investigated the physicochemical and antioxidant properties of sponge cakes made using different amounts (2 and 4%) of barley sprout powder (BSP) and green tea powder (GTP), respectively. The results showed that the baking loss rate of GS2 (2% green tea) and GS4 (4% green tea) was 12.39% and 11.96%, respectively in the green tea addition group, which was higher than that of the barley sprout group, but significantly lower than that of the control group at 13.34% (p<0.05). The specific volumes of the sponge cake containing barley sprout and green tea 2% and 4% were between 2.84- 2.95 mL/g, which was significantly higher compared to the control group at 2.69 mL/g (p<0.05). The sugar content was significantly higher in the control group and the barley sprout addition group at 2.30oBrix (p<0.05). As for the volume index, the control group with the lowest value at 13.43 showed a significant difference compared to the addition groups. The volume index significantly decreased as the addition amount increased, measuring 14.07 in BS4 (4% BSP) compared to 14.87 of BS2 (2% BSP) in the barley sprout group (p<0.05). In cross-sectional photography, the color became darker than that of the control group as the quantum of additives increased. In terms of the DPPH and ABTS radical scavenging activity, the total phenol content, and total flavonoid content, the groups with the addition of barley sprout and green tea showed higher antioxidant activity than the control group (p<0.05).

This study was carried out to compare the quality characteristics and antioxidant activity by varying the barley sprout powder addition time, production temperature, and powder addition ratio (0, 2, 4, 6, 8%) on the prepared rice during the manufacturing process of Nurungji. When we manufactured for 2 min at 200oC, the total polyphenol and flavonoid contents were the highest in Nurungji with 4% of barley sprout powder. In this way, we measured the weight, water content, water binding capacity, soluble solids content, reducing sugar, color, hardness, sensory evaluation experiments by varying the powder content. The weight, water binding capacity, soluble solids content, reducing sugar, and hardness increased with an increasing proportion of barley sprout powder, however the water content decreased. The L value and b value decreased and the a value increased with the influence of chlorophyll pigments in barley sprout. Sensory evaluation showed that Nurungji with 4% sprout barley powder was the highest. Therefore, we judged that it is desirable to add 4% of the powder when manufacture the barley sprout powder Nurungji.

The purpose of this study was to evaluate the quality characteristics of white pan bread added with wheat sprout powder without treatment (WP) and wheat sprout powder with only enzyme treatment (WPE), only lactic acid bacteria treatment (WPL) and enzyme and lactic acid bacteria treatment (WPE&L). The three different powder concentration levels of 1%, 3%, and 5% were added to flour to produce the white pan bread. The bread volume and specific volume of the WPE&L group were the highest among all the addition groups. The bread weight, a-value, and b-value of the WP group was highest among all the addition groups, but the bread baking loss and the L-value of the WP group was the lowest among all the addition groups. The texture measurements indicated that the hardness, gumminess, and chewiness values of the bread were the highest in the WP group. The sensory evaluation test showed that bread in the WPE&L group with 3% wheat sprout powder was the best among all the samples studied. Based on our findings, we suggest that the enzyme and lactic acid bacteria pretreated wheat sprout powder is an effective ingredient for improving the overall quality of white pan bread.

The purpose of this study was to evaluate the physicochemical components and antioxidant activities of wheat sprout powder prepared by the enzymatic hydrolysis and lactic acid bacteria treatment. The four kinds of pre-treatment were: no treatment (WP), treated with enzyme (WPE), treated with lactic acid bacteria (WPL), and treated with enzyme and lactic acid bacteria (WPEL) were applied to the wheat sprout powder. The WPEL had higher total free amino acid and essential amino acid content than the other samples. As for the volatile aroma of the wheat sprout powder, 29 types of compounds were identified in the WP and WPL, 28 types in the WPE, and 27 types in the WPEL, respectively. The total polyphenols and flavonoids contents, in the wheat sprout powder was enhanced with the enzyme and the lactic acid bacteria pre-treatment. The WPEL had highest DPPH radical scavenging activities. The overall acceptability was the highest at 6.24 points in the WPEL. Based on these observations, it was confirmed that the enzyme and lactic acid bacteria pre-treatment could improve the antioxidant activities and active component of the wheat sprout powder.

The physicochemical and antioxidant properties of cookies prepared using powders of barley sprout (BS), lemon balm (LB), and green tea (GT) were studied. The same dough density was maintained in all the sample groups. The experimental group to which the natural ingredients containing antioxidants were added did not show any significant change in the appearance of cookies compared to the control. LB and GT cookies showed significantly lower hardness compared to the control (p<0.05). Control showed the lowest antioxidant effect when assessed with 2,2-diphenyl-1-picrylhydrazyl. (DPPH) and this gradually increased in the order of BS, LB, and GT. The antioxidant activity of GT was 7 times higher as compared to the control (p<0.05). The antioxidant activity assessed using 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) also showed results similar to that seen with DPPH. GT showed a significantly higher total phenol content, about 2-3 times higher compared to the control (p<0.05). GT had significantly higher total flavonoid content than that of the control (p<0.05). Thus, the addition of natural antioxidant ingredients such as sprout barley, lemon balm and specifically green tea, in the preparation of cookies, resulted in excellent antioxidant activity with similar physicochemical quality characteristics. The study suggests that it is possible to develop cookies that are competitive in terms of nutritional and physiologically active functions.

The purpose of this study was to determine the content of polyphenols and flavonoids, vitamin C, and antioxidant activity for the extract from the Deodeok sprout. To accomplish this, the Deodeok sprout whole (CLS-W), above ground part (leaf, stem, CLS-L), and root (CLS-R) were individually extracted using 70% ethanol. The highest levels of total polyphenols and total flavonoids were observed in the Deodeok sprout extract CLS-L2. Similarly, antioxidant activities resulting in radical scavenging activities increased significantly in the extract of CLS-L2. In conclusion, these results indicate that Deodeok sprouts can be used as a viable, new natural antioxidant source.
