The effects of modified atmosphere(MA) storage for fresh red chili pepper and red bell pepper fruits were investigated with storing in polyethylene film with various fine holes. During the storage of the both pepper fruits, the weight loss, color change, mold emergence, and firmness were evaluated. The weight loss of pepper fruits packaged without holes on film was less than 3%, even though it was each 50% and 25% for non packaged red chili pepper and red bell pepper fruits. The rates of mold emergence of red chili pepper and red bell pepper fruits were reached to each 60% and 50% at the end of storage period as stored in film without holes. However, the rate of mold emergence of pepper fruits was lowered when fruits were stored in MA with low relative humidity (70∼80%). The color and firmness of pepper fruits were not much changed when fruits were stored in MA with high humidity.

Our previous study detected aflatoxins in red chili peppers from Chile, Bolivia, and Peru, each of which have a high incidence of gallbladder cancer (GBC). Since the aflatoxin B1 concentration was not so high in these peppers, it is important to clarify the presence of other mycotoxins. Here we attempted to determine any associations between the concentrations of aflatoxins and ochratoxin A (OTA) in red chili peppers, and the corresponding GBC incidences. We collected red chili peppers from three areas in Peru: Trujillo (a high GBC incidence area), Cusco (an intermediate GBC incidence area), and Lima (a low GBC incidence rate), and from Chile and Bolivia. Aflatoxins and OTA were extracted with organic solvents. The concentrations of aflatoxins B1, B2, G1, and G2, and OTA were measured by high-performance liquid chromatography. The values obtained were compared with the incidence of GBC in each area or country. All of the red chili peppers from the three areas showed contamination with aflatoxins below the Commission of the European Communities (EC) recommended limits ($5{\mu}g/kg$), but the OTA contamination of two samples was above the EC recommended limit ($15{\mu}g/kg$). The mean concentrations of OTA in the peppers from Chile (mean $355{\mu}g/kg$, range < $5-1,059{\mu}g/kg$) and Bolivia (mean $207{\mu}g/kg$, range $0.8-628{\mu}g/kg$), which has a high incidence of GBC, were higher than that in Peru ($14{\mu}g/kg$, range < $5-47{\mu}g/kg$), which has an intermediate GBC incidence. The OTA contamination in the red chili peppers from Chile, Bolivia, and Peru was stronger than that of aflatoxins. Our data suggest that OTA in red chili peppers may be associated with the development of GBC.

In order to extend the shelf-life of red chili pepper, MA and CA technology were used. In MA storage, red chili peppers(Jinmi and Jangkun) were packaged in 0.03 mm PE film bags(3 kg/bag) having two holes(${\sigma}$2~3 cm) at 2~3$^{\circ}$C or 7~8$^{\circ}$C. In CA storage, red chili peppers(Jinmi) were stored on following gas composition; 5 or 10% CO$_2$ in combination with 2 or 5% O$_2$ at 2~3$^{\circ}$C, respectively. The changes of weight loss and decay rates during MA storage were less in Jinmi than in Jangkun and less at 2~3$^{\circ}$C storage(except O$_2$ 5%, CO$_2$ 10% condition) while in CA it decreased after 40 days of storage. Red chili peppers would be stored for 30 days when stored in MA conditions(0.03 mm PE film bag) and for 60 days when srored in CA condition on O$_2$ 2%, CO$_2$ 10% based on overall quality of sensory evaluation.

Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

Our recent studies conducted in South America have shown that mycotoxin contamination of red chili peppers (RCPs) may be associated with an increased risk of gallbladder cancer (GBC). Whether this relationship exists in India, a country with a high incidence of GBC and high consumption of RCPs, is unclear. We therefore measured concentrations of aflatoxins (AFs) and ochratoxin A (OTA) in RCPs from areas of low, medium, and high incidence of GBC in India, and compared these concentrations with GBC incidence in each area. Twenty-one RCP samples were collected from nine cities (eight from a low-incidence area, five from a medium-incidence area, and eight from a high-incidence area). Concentrations of AFs and OTA were measured using high-performance liquid chromatography. No significant differences in mean concentrations of AFs and OTA were found in the three areas. AFB1 levels in the low-incidence area ($10.81{\mu}g/kg$) and high-incidence area ($12.00{\mu}g/kg$) were more than 2.2 and 2.4 times higher compared with the maximum permitted level of AFB1 in spices ($5.0{\mu}g/kg$) set by the Commission of the European Communities, or that ($4.4{\mu}g/kg$) obtained in our previous study in Chile. Our results show that the mean concentrations of mycotoxins in RCPs are similar among the three areas in India with different incidences of GBC. Further studies with human subjects are needed to evaluate any association between AFB1 and GBC.

The origin of Korean traditional food's spicy taste dates back to the first telling of the Dangun myth-a story of a tiger and bear who tried to reincarnate themselves in human form by eating garlic and wormwood. For a long time, Koreans have eaten spicy vegetables such as green onion, garlic, ginger, mustard, leeks, corni, cinnamon bark, and Chinese peppers (Zanthoxylum schinfolium) and Zanthoxylum bungeanum. In prehistoric times, spicy vegetables were probably used to eliminate the smell of meat. In the agricultural age, they were used to supplement meals with fresh taste. They were also used as a substitute for salt (salt was very precious and expensive) as well as side dishes for the poor. Spicy vegetables have also been used as a substitute for main dish like medicinal gruel and used to increase the spiciness of soup, and they are usually used as a side dish and with condiments in namul (cooked vegetable dishes), sangchae (salad), ssam (wrapped in greens and garnished with red-pepper paste or other condiments) and Kimchi. In addition, chili pepper was introduced to the Korean Peninsula in the middle of the Joseon Dynasty (mid-15th, 16th century). The soil and climate of the Korean Peninsula are suitable to growing chili pepper, and chili pepper has excellent adaptability and productivity. Accordingly, it is processed to red pepper powder and has become a major part of traditional Korean food along with Chinese pepper. Since the Joseon Dynasty, many kinds of Kimchi made with red pepper powder have been developed, and most Koreans enjoy them these days. The main characteristics of Korean food are spiciness and honest-to-goodness taste.

Since 2012, despite the fact that tariff rate quotas (TRQ) in the form of dried peppers has not been imported, the imports of pepper-related items such as low- tariff frozen peppers (27%) and other sauces (45%) have increased, there has been a problem in the domestic pepper industry, in which the domestic self-sufficiency rate has declined. The purpose of this study was to find out whether the operation of chili pepper TRQ has the effect of suppressing the imports of pepper-related items from China. We analyzed the import substitution effect (import suppression effect) through causal analysis of the imports of red pepper TRQ, frozen peppers, and other sauces using the structural equation model analysis method. As a result of the hypothetical scenario analysis, when the government imports and releases 7,185 tons of pepper TRQ in 2019/20 (scenario), private imports were estimated to decrease by only 3,060 tons. In other words, the import substitution effect between imported items was estimated to decrease about 2,079 tons of private dried peppers, and about 981 tons of imported pepper-related items. There was an effect of suppressing the imports of pepper-related items such as frozen peppers, but it was analyzed to be insignificant. That reason was that the replacement substitution elasticity of the pepper-related items for TRQ import was less than 1 (inelastic). Therefore, it is judged that the government's operation of the pepper TRQ is preferably focused on stabilizing domestic prices rather than focusing on import control of pepper-related items.

생홍고추 및 생홍피망의 장기저장 방법으로 HDPE 및 LDPE포장내에 시료와 함께 서로 다른 양의 NaCl을 삽입함으로써 MA저장 효과를 조사하였다. HDPE 및 LDPE 포장내의 NaCl 함량은 0 g, 15 g, 20 g, 25 g이었으며, 대조구로 무포장이 사용되었다. 홍고추 및 홍피망의 각각 50일 및 35일간 MA저장 동안 주기적으로 중량 변화와 곰팡이 발생율을 조사하였고, 저장 초기와 말기에는 색도와 경도를 측정·비교하였다. NaCl을 포함하지 않은 처리구에 있어 HDPE와 LDPE 포장 모두 홍고추 및 홍피망의 중량 감소율은 각각 4∼5% 및 3∼4%의 범위로 매우 낮았다. 그러나, 대조구인 무포장의 경우 중량 감소율이 저장 말기에 홍고추 및 홍피망 각각 45%와 22%로 높게 나타났다. 또한, 포장 내에 NaCl을 포함한 경우 홍고추 및 홍피망의 중량 감소율은 각각 19% 및 6% 이하로 무포장에 비해 매우 낮게 나타났다. 무포장인 홍고추 및 홍피망의 저장에 있어 곰팡이 발생율이 각파 5% 및 12.5%로 매우 낮았으나, NaCl을 포함하지 않는 HDPE 및 LDPE 저장에 있어서는 55∼65%로 매우 높게 나타났다. NaCl 함유량이 15 g, 20 g 및 25 g 일 때 HDPE 및 LDPE 포장에 저장된 홍고추 및 홍고추의 곰팡이 발생율은 20∼45%의 범위로 나타났다. NaCl을 포함하지 않는 HDPE와 LDPE 포장내에 저장된 홍고추 및 홍피망의 색도차는 각각 0.74와 1.50 이하로 매우 낮았다. 또한, 15∼25 g의 NaCl을 포함하는 MA 저장된 홍고추 및 홍피망의 색도차도 각각 0.85∼0.88 및 1.56∼1.61의 범위에 있었다. 그러나, 저장습도가 낮은 무포장의 경우 홍고추 및 홍피망의 색도차는 각각 1.15 및 1.78로 다른 처리구보다 매우 컸다. 무포장의 경도감소는 홍고추 및 홍피망이 각각 1.70 kg 및 0.71 kg으로 크게 나타났으나, 무포장에 비해 NaCl을 함유한 HDPE 및 LDPE 포장의 경우 홍고추 및 홍피망의 경도 감소는 각각 0.75∼1.02 kg 및 0.15∼0.49 kg의 범위로 낮게 나타났다.

The objective of this study was to understand the combined effect of shading treatment and harvest time on pungency, ascorbic acid content, market-quality pepper yield, and photosynthetic activity in a yellow 'Star Flame' and 'Fire Flame' F1 hybrid pepper cultivar (Capsicum annuum). Plants were cultivated in a greenhouse under white, red, and green shading nets and compared to those grown under unshaded control conditions. The ascorbic acid and pungency parameters were analyzed by high-performance liquid chromatographic methods. Ascorbic acid, a compound of high nutritive value in pepper, was highest in fruits gathered during the first summer harvest in both hybrids. The ascorbic acid content was found to be further increased in fruits from plants grown under white net shading in both 'Star Flame' and 'Fire Flame'. Total capsaicinoid contents in 'Star Flame' were influenced by the interaction of shading treatment and harvest time (p = 0.004), with the lowest amounts ($241.2-251.5mg{\cdot}kg^{-1}$ fresh weight) resulting from white and red shading treatments at the early autumn harvest. In 'Fire Flame', both shading treatment (p = 0.009) and harvest time (p < 0.001) affected total capsaicinoid contents. We observed significantly higher total capsaicinoid contents in control fruits compared to that resulting from red and green shading treatments at the second harvest, and that resulting from red shading treatment at the third harvest. Analysis of photosynthetic activity revealed a significant and negative correlation between Fv/Fm values and total capsaicinoid contents in both hybrids (p < 0.001). Based on the obtained results, the harvest of peppers during summer should be promoted to produce fruits with high pungency.
