The purpose of this study was to examine purchasing behavior and consumption frequency of fruits, and perception of imported fruits among housewives living in small cities. A questionnaire survey was conducted to 265 housewives living in Cheongju, Suwon and Pohang from May to June in 2015. The place to buy fruits were fruit shop (30.9%), large discount store (25.3%), nearby supermarket (17.7%), and traditional markets (16.6%). When purchasing fruits, 34.3% answered they always checked their country of origin, 34.7 % answered ‘sometimes’, and 25.7% seldom checked, and 5.3% never checked. While 53.6% preferred domestic fruits, 46.4% preferred imported fruits or they do not care about the country of origin. These purchasing behaviors of fruits were significant different according to age. More than 90% had experience in purchasing imported fruits. Fruit consumption frequencies were higher in the group aged 50 or older than the group aged less than 40. Apple and tangerine were the most frequently consumed domestic fruits, and banana and orange were the most frequently consumed imported fruits. The most important factors for choosing fruits were taste, freshness, safety, price, nutrition in the order. They perceived imported fruits as tasty and having different types and flavor, but negatively perceived in terms of freshness, safety and hygiene. While the housewives thought that taste, freshness, and safety were the most important factors for choosing fruits, they do not think imported fruits were fresh, safe, and hygienic.

This paper analyzes substitution relationships between domestic fruits and imported fruits with a consideration taken into the seasonality in their demand and supply. For the analysis, we develop an extended Inverse Almost Ideal Demand System into which a cyclical functions are incorporated and then apply the demand system model to three domestic fruits of apple, watermelon, tomato and three imported fruits of orange, banana, and grape. We split the data set into two periods, before and after the Korea-Chile FTA, and compare various parameter estimates obtained from the demand system model between two periods. Estimated results on own, cross and scale flexibility parameters show that imported fruits have become stronger substitutes for domestic fruits after rather than before the FTA. Cyclical parameter estimates such as amplitudes and phases present that demand for domestic fruits has been more sensitive to fruits price changes after rather than before the FTA. In addition, the results indicate that there exist statistically significant changes at between two periods in terms of the delivery timing and share of domestic fruits into the markets. Results of this paper provide useful information to establish a program supporting domestic fruits producers who may not receive direct payments from the government because of producing fruits which are not botanically homogeneous as imported fruits.

The purpose of this study is to analyze purchase status of imported fruit and the characteristics of consumers preferring to imported fruit. So, we surveyed consumers and analyzed the factors affecting the intention to expand the purchase of imported fruits using the probit model. As a result of the probit model analysis, the ‘price satisfaction’ of imported fruits represents the greatest marginal effect on the intention to expand the purchase of imported fruits. This means that consumers who are highly satisfied with the price after purchasing imported fruits are most likely to buy more imported fruits. In the analysis of demographic characteristics, we have found that consumers with lower income are more willing to buy imported fruits and substitute for domestic fruits. So, we make conclusion that the low price of imported fruits have a positive effect on the intention to expand the purchase of imported fruits in low income households. The ‘satisfaction with taste’ of imported fruits showed a marginal effect as much as ‘Satisfaction with price’. Considering this, it seems that consumer's satisfaction with price and taste after purchasing imported fruits is the main factors of expanding imported fruit. Meanwhile, ‘Consumer considering that health is important’ among the attributes of purchasing agricultural products had a negative impact on the intention to expand the purchase of imported fruits. Based on these results, the greatest strength of domestic fruits that can differentiate from imported fruits is thought to be health benefit. For this purpose, it will be necessary to expand quality control efforts such as environment-friendly certification and GAP certification. Also, it would be necessary to actively promote that seasonal domestic fruits have a good nutritional content. In addition, it would be important to make effort to enhance the taste and price competitiveness of Korean fruits.

복숭아 雙子果에 關한 연구

유영산,김도균 대구효성가톨릭대학교 1997 연구논문집 Vol.56 No.2

최근 油桃系 복숭아에서 발생하고 있는 雙子果의 類型과 재배품종, 樹齡, 결과지 종류, 기상, 생장조절제처리 등에 따른 발생정도를 조사하여 다음의 결과를 얻었다. 1. 복숭아 雙子果는 암술이 두개 착생된 雙子房花가 결실된 것으로서 受精 여부에 따라 'doubled fruit'형과 'spurred fruit'형으로 구분되었다. 2. 雙子果는 털이없는 油桃系 품종에 주로 발생되었으며 발생이 많은 품종은 'Armking', 'May Grand'and 'Chunhong'등 早生種 品種에서 였다. 3. 雙子果의 발생은 花芽分化期인 7~8월의 고온 건조시 그 이듬해에 많이 발생되었다. 4. 雙子果의 발생은 수세가 강한 유목, 세력이 강한 樹冠上部의 從長枝, 직사광선을 받기쉬운 樹冠의 동향 및 남향에서 발생이 많았다. 5. GA₃처리는 쌍자과의 발생을 억제시켰으나 꽃눈이 탈립되는 부작용을 보였으며 반면에 paclobutrazol 처리는 쌍자과의 발생을 증가시키는 경향을 보였다. 6. 雙子果의 발생은 7~8월의 지나친 高溫乾燥시 증가하므로 적절한 灌水가 발생을 줄일 수 있는 방법이라 생각되었다. This experiment was conducted to investigate the cause of occurrence and types of peculiar doubed fruits which occured recently in peach orchards. And it was also concucted to investigate the occurrence degree of doubled fruits as influenced by peach cultivar, tree age, fruiting branch, weather, and application of growth regulators. The results obtained in this experiment are summarized as follows. 1. The doubled fruits were developed from malformed flowers with two pistils. Doubling of fruits was divided into two types: 'doubled fruit' from fertilization of two pistils and 'spurred fruit' from fertilization of only one pistil. 2. The doubled fruits were seldom occured in the tomentose peach cultivars and mainly occured in the nectarine cultivars. The doubled fruits were often occured in early maturing cultivars such as 'Armking', 'May Grand'and 'Chunhong'. 3. The occurrence of doubled fruits increased in the vigorous young tree, water sprout of the upper canopy and eastern and southern part of tree canopy. 4. When the period of flower bud differentiation was high temperature and low humidity, The occurrence of doubled fruits was increased in the next year. 5. Treatment of GA₃reduced the occurrence of doubled fruits, treatment of paclobutrazol apparently increased the doubled fruits in 'May Grand' nectarine. 6. The occurence of doubled fruits was assumed to be due to a previous hot-dry season during the flower bud differentiation period, Thus, it was speculated that a frequency of doubled fruits may be reduced by irrigation.

‘Hanareum’ pear is expected to produce the high quality small and medium-sized fruits without any majorchanges in the current cultivation techniques, inasmuch as its basic characteristics are already included in the rangeof small and medium-sized fruits. Thus, we tested the possibility of utilization of ‘Hanareum’ pear for producingsmall and medium-sized fruits, while establishing the limit of minimum fruit weight for the fruits in high quality. With the results of correlation analysis, it was possible to predict the fruit weight through the observation of solublesolid contents and flesh firmness, because both factors were closely correlated to fruit weight in all treatments. Moreover,these factors were confirmed to be useful indicators of forecasting consumer preference in the sensory evaluation. The fruit marketability was excellent under the conditions that were greater than 11.6oBx and less than 25.6 Nfor soluble solid contents and flesh firmness, respectively. When applying these standards of fruit quality to theresults of regression analysis for fruit weight, non-treated fruits fulfilled both standards when the fruit weight washigher than 436 g, and the quality uniformity was also high on this state. Therefore, the production of high qualitysmall and medium-sized fruits was determined to be under this condition. The weight limit for GA treated fruits was620 g, and both fruit quality and uniformity were below the weight range of small and medium-sized fruits, with300~500 g. Thus, GA treatment was suggested to be avoided, in order to produce the high quality small andmedium-sized fruits. ‘한아름’ 배는 기본적인 품종 특성이 중소과 범주에포함되는 품종으로 재배기술의 큰 변화 없이도 고품질의중소과 생산이 가능할 것으로 예상되는 품종이다. 따라서, 본 연구에서는 ‘한아름’ 품종을 대상으로 중소과로의활용 가능성을 알아보고, GA 처리와 비교하여 고품질의중소과 생산이 가능한 최저 과중 기준 설정하고자 하였다. 과실 품질인자간 상관분석 결과, 무처리구와 GA 처리구에서 공통적으로 과중과 당도, 과중과 경도가 높은상관관계가 있어 각 처리구의 당도와 경도의 관찰을 통한 과중의 예상이 가능하였다. 또한, 당도와 경도는 소비자 선호도를 예측하는데 유용한 지표로 확인되었으며,당도가 11.6oBx 이상, 경도가 25.6N 이하의 과실이 상품성이 높은 것으로 조사되었다. 관능평가를 통해 도출된품질 기준을 각각 과중과의 회귀분석 결과에 적용한 결과, 무처리구는 과중 436g 이상의 과실이 당도와 경도의품질 기준을 충족하였으며, 품질 균일도 또한 높아 436g이상의 과실을 수확하면 고품질의 중소과 생산이 가능할것으로 판단되었다. GA 처리구에서 당도와 경도의 품질기준을 모두 충족시키는 최소 과중은 620g으로, 중소과범위에서는 품질이 낮고 불균일하여 고품질의 중소과 생산을 목적으로 재배할 경우, GA 처리는 지양해야 할 것으로 판단되었다.

Fruits are generally recommended for a balanced meal, as they are good sources of vitamins, minerals, and fiber, which may improve blood glucose control. However, fruits have simple sugars with a wide glycemic index (GI) range. The purpose of this study was to analyze the sugar content and composition and to determine the glycemic indices of the most frequently consumed fruits in Korea, including apple, tangerine, pear, water melon, persimmon, grape, oriental melon, and peach. The sugar content and composition of the fruits were analyzed by high performance anion-exchange chromatography (Dinonex model DX-600). The GI of the fruits was measured in 13 healthy subjects (seven females and six males) after permission was received from the University Hospital institutional review board (KHU-IRB 1114-06). The subjects consumed 50 g of glucose as a reference and carbohydrate portions of eight fruits. Blood samples were collected at 0, 30, 60, 90, and 120 min after consuming the fruits. The GI values for the fruits were calculated by expressing the increase in the area under the blood glucose response curve for each subject. As a result, the total sugar contents of 100 g fruits were: grape (13.9 g), apple (12.3 g), persimmon (11.9 g), oriental melon (11.2 g), watermelon (9.3 g), tangerine (8.9 g), peach (8.6 g), and pear (8.3 g). The GI values of the fruits were as follows: GI value of peach (56.5 ± 14.17), watermelon (53.5 ± 18.07), oriental melon (51.2 ± 18.14), tangerine (50.4 ± 15.16), grape (48.1 ± 14.05), persimmon (42.9 ± 18.92), pear (35.7 ± 14.38), and apple (33.5 ± 11.92). These findings will help individuals choose fruit for controlling blood sugar. (Korean J Nutr 2012; 45(2): 192 ~ 200)

This study is to analyze consumption charateristics of imposrt fruits and to investigate the substitution effect between imported fruits and domestic fruits by using food consumer panel pooling data. We adopted Panel Regression Analysis to confirm those characteristics. We analyzed imported fruits as three groups such as existing imported fruits, new taste imported fruits and health function imported fruits. Analysis results found that existing group is analogous characteristic to domestic fruits. And new taste group and health function grouup increase consumption in small family and high-income households. Also apple and pear are substituted for health function imported fruits. Mandarin, persimmon and oriental melon are substituted for new taste imported fruits. This can produce a sales strategy ofr domestic fruits production firms.

This study investigates the factors affecting the purchase frequency of foreign-species fruits, using the panel data of ｢Food Consumption Behavior Survey｣ from Korea Rural Economic Research Institute for the period from 2017 to 2020. The recursive bivariate ordered probit model is applied to consider the dependent correlation between the purchase frequency of foreign-species fruits and the purchases frequency of common fruits in estimating the model. The results find that the higher the purchase frequency of fruits, the higher the purchase frequency of foreign-species fruits was statistically significant, indicating that households who consume more fruits also purchase more foreign-species fruits. It can be seen that consumers are young, high-educated and high-income groups. Also, the information provided through SNS has been shown to have a positive effect on the purchasing power of foreign-species fruits, suggesting the importance of social networks as a promotional method to expand consumption of fruits including foreign-species fruits.

The Promise of Dried Fruits in Cancer Chemoprevention

Kundu, Joydeb Kumar,Chun, Kyung-Soo Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.8

Chemoprevention is an attempt to use nontoxic natural and synthetic substances or their mixtures to intervene the relatively early stages of carcinogenesis, before invasive characteristics are manifested. The consumption of fruits is well known to reduce the risk of human cancers. Although most fruits are available only on a seasonal basis, recent advances in food processing technologies have made it possible to extend the shelf life of fruits and fruit-products. Fruits can be preserved by applying different drying processes to reduce the moisture content. Different varieties of dried fruits are now sold in supermarkets, thereby making them readily accessible to consumers. Since oxidative stress and chronic inflammation play important roles in cancer development, dried fruits with antioxidative and anti-inflammatory properties hold promise for cancer chemoprevention. The antioxidant, anti-inflammatory and chemopreventive activities of dried fruits are largely attributed to their polyphenols and vitamins. Dried fruits contain adequate amounts of bioactive principles, such as anthocyanins, acetogenins, catechins, coumarins, phenolic acids, terpenes, xanthones, and others. Since numerous health beneficial phytochemicals in fruits are conserved even after processing, regular intake of dried fruits can help prevent cancer. This review addresses the chemopreventive potential of representative dried fruits and their active constituents.

Fruits are good sources of vitamins, minerals, fiber, and phytochemicals, which are known to reduce serum lipids, oxidative damage, and blood pressure as well as improve blood glucose control. The purpose of this study was to estimate nutrient quality indices of fruits by carrying out a critical analysis of pre-existing methods according to their nutritional compositions. Four methods were used to assess the nutrient indices of 26 fruits, which are frequently consumed by Koreans based on the fourth Korean National Health and Nutrition Examination Survey (2009). Naturally nutrient rich score (NNR), nutrient rich food (NRF), nutrient adequacy score (NAS), and nutrient density score (NDS) were used to calculate nutrient quality indices. The Korean Nutrition Society Food Composition database of fruits based on 100 g edible portions was used. The algorithm of each method included the mean percentage of daily values (Dietary Reference Intakes for Koreans, 2010) for particular nutrients based on consumption of 1,900 kcal/day. The relative score indicated that strawberries, kumquat, and lemon had high nutrient quality indices. In addition, mango, lemon, persimmon, strawberry, apricot, and tangerine fruits are rich in antioxidant nutrients such as β-carotene, vitamin C, vitamin E, and selenium. However, scores of nutrient quality indices did not imply that higher scores of particular fruits are superior. We suggest moderate seasonable consumption a variety of fruits. Our results can be used as a reference for consumers when they choose fruits.
