본 연구에서는 새싹종자 소독처리 여부에 따른 재배기간별 미생물 오염도 수준을 파악하고, 종자소독이 발아율에 미치는 영향을 분석하였다. 수입산 새싹종자 알팔파(alfalfa), 브로콜리(broccoli), 클로버(clover), 적양배추(red cabbage), 적무(red radish) 5종에 대하여 소독제 처리 여부에 따른 발아율과 재배기간별 미생물 분석을 실시하였다. 소독제 종류에 관계없이 새싹종자(알팔파, 클로버, 적무)는 48시간 후 90% 이상 높은 발아율을 보였다. 종자 소독 시 식중독균은 검출되지 않았고, 대조군에 비하여 유의하게 낮은 미생물 수준을 보였으나, 발아과정에서 일반세균, 대장균군 모두 $10^7-10^8CFU/g$으로 종자소독 여부에 관계없이 종자에 비하여 유의하게 높은 오염 수준을 나타내었다(p<0.05). 또한 종자 소독하지 않은 클로버에서 Listeria monocytogenes 이 검출되었다. 따라서 새싹채소의 위생적인 안전성을 개선하기 위하여 미국 FDA 권고에 따라 재배전 종자의 소독이 필요하며, 발아과정의 HACCP 관리계획을 마련하여 중점적으로 관리하는 것이 필요하겠다.

Fresh sprouts such as alfalfa, mung bean, radish, broccoli, and soybean sprouts have become very popular due do their high nutritional value. However, there have been several outbreaks of illness in the last few years that have been attributed to sprout consumption. A number of methods have been used to improve the safety of seed sprouts. One promising technology is the use of ionizing radiation treatment. Irradiation with doses up to 8 kGy has been approved in the USA to control microbial pathogens in seeds intended for sprout production. This review focuses on the potential use of ionizing radiation in reducing the pathogen levels in seed sprouts. The effects of irradiation on seed germination and the nutritional quality of the sprouts are discussed.

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.

The study was conducted to identify the anti-inflammatory and anti-cancer effects in sprouts of mouse-eyed bean (Rhynchosia nulubilis), ginseng (Panax ginseng), perilla (Perilla frutescens), broccoli (Brassica oleracea var. italica), and lettuce (Lactuca sativa) grown with organic germanium concentrate. Western blot analysis was performed to assess the anti-inflammatory activity of the extract. All extracts exhibited noticeable anti-oxidant activity, indicating a significant correlation between the germanium content and anti-oxidant activity (p<0.05). In particular, rat-eyed bean sprouts with the highest germanium content showed significant anti-inflammatory activity (p<0.05) by significantly inhibiting the expression of the inflammatory complexes, NLRP3, cytokines IL-1β and caspase-1. Ginseng and broccoli sprouts showed strong anti-cancer properties and had high anti-oxidant effects (p<0.001). Germanium-concentrated water allows the mass production of agricultural products containing high concentrations of organic germanium. Agricultural produce grown with germanium concentrate add organic germanium to various physiological active ingredients, increasing the anti-oxidant and anti-cancer effects. These results strongly suggest that agricultural products containing high germanium concentrations can be used as novel health supplements to improve health.

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 FD-YB 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-α and Interleukin-6). In conclusion, FD-YB can be a potential nutraceutical for preventing and regulating excessive immune responses during inflammation.

저장중 5가지 싹채소, (무, 적무, 적양배추, 알팔파, 브로콜리)의 생체중은 $50{\mu}m$ LDPE필름으로 밀폐하여 $2^{\circ}C$와 $8^{\circ}C$모두 99%이상 유지되었다. 저장중 포장재내 이산화탄소 농도는 $8^{\circ}C$에서 $2^{\circ}C$에서 보다 높았으며 작물별로 무와 적무가 높았다. 산소농도는 이와 정반대로 $2^{\circ}C$에서 높게 유지되었고, 무와 적무가 가장 낮은 농도를 보였는데 특히 $8^{\circ}C$저장 3일째는 3%미만까지 낮아지기도 하였다. 에틸렌 농도도 $2^{\circ}C$에 비해 $8^{\circ}C$에서 다소 높았으며 작물별로는 알팔파가 0.1ppm으로 가장 낮았고 나머지 4 작물은 작물간 농도차이에 유의성 없이 1ppm미만으로 낮았다. 이취는 산소농도가 가장 낮았던 무와 적무에서 오히려 낮은 수준을 보였으며 온도별로 큰 차이가 없었다. 외관상 품질은 역시 $2^{\circ}C$가 $8^{\circ}C$보다 높게 유지되었으며, 두 온도 모두에서 무가 가장 높게 유지되었고, 다음으로 적무, 브로콜리, 적양배추, 알팔파 순서였다. 이상의 결과에서 싹채소의 작물간 저장성에 차이를 알 수 있었는데 무와 알팔파의 경우 $4{\sim}5$일의 저장기한의 차이를 보였다. 따라서 싹채소 유통에 있어 작물별 관리가 다르게 실시되어야 할 것이라 생각된다.

Broccoli sprouts are an excellent source of health-promoting phytochemicals, such as glucosinolates, phenols, and vitamins. In this investigation, oil extracted from broccoli was adjusted to various concentrations (control, 1%, 2%, 3%, 4%, and 5%, respectively) and added directly to dairy products (cow milk, yoghurt, and kefir) and non-dairy products (soy milk), and their organoleptic properties assessed. The results showed that when the amount of broccoli oil was increased, the organoleptic properties (texture, color, and flavor) and overall acceptability tended to decrease. Cow milk, yoghurt, kefir, and soymilk supple-mented with 1% broccoli oil showed the best organoleptic properties when compared to the control group. The fermented products such as yoghurt and kefir with added broccoli oil showed good organoleptic properties. Overall, the results of this study provide evidence for the use of broccoli oil in dairy and non-dairy products. Further research will be required to assess the various physiological active functions of broccoli oil.

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.

We analyzed the ${\gamma}$-aminobutyric acid (GABA) content of a selection of uncooked foods. Foods with GABA concentrations in excess of 100 nmole per g dry weight included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, brown rice, spinach, potatoes, sweet potatoes, yams, kale and chestnuts. Cereals included: brown rice germ, brown rice sprouts, barley sprouts, bean sprouts, beans, corn, barley, and brown rice and had GABA concentrations of 718, 389, 326, 302, 250, 199, 190, and 123 nmole per g dry weight (DW), respectively. The vegetables: spinach, potatoes, sweet potatoes, yams and kale contained 414, 166, 137, 129, 122 nmole GABA per g DW, respectively. The GABA concentration of chestnut was 188 nmole per g DW. However, oatmeal, adlay, broccoli, squash, carrots, onion, apples, lentinus edodes, green laver, and lactobacillus had GABA concentrations of less than 100 nmole per g DW. These results show that brown rice germ, sprouted cereals and spinach are good sources of plant-derived GABA. These data will be useful in selecting foods for the manufacturing of uncooked foods containing a relatively high concentrations of GABA.
