국내에서 많이 재배되는 5가지 품종의 감자 중에서 French-fried potato 제조에 적합한 품종을 선정하고, 이를 원료로 제조한 French-fried potato의 텍스쳐 품질을 향상하기 위한 처리효과를 조사한 결과는 다음과 같았다. 시험한 다섯가지 감자품종 중에서 Superior를 French-fried potato 제조용으로 선정하였다. Superior를 원료로 하여 French-fried potato를 만들 경우 제품의 crispness를 증진시킬 수 있는 처리로, 데치기한 감자 strips을 1시간 이상 대기건조 후 튀김하는 방법, 데치기한 감자 strips을 6%, 전분용액($60^{\circ}C$)에 2분간 침지한 다음 튀김하는 방법, 데치기한 감자 strips을 1.5% HPMC($60^{\circ}C$) 용액에 약 20초 침지한 다음 튀김하는 방법, 데치기한 감자 strips을 한 시간 이상 대기건조한 다음 1.5% HPMC 용액에 약 20초 침지한 뒤 튀김하는 방법이 효과가 있었다. 그 중에서 특히 데치기한 감자 strips을 한 시간 이상 대기건조한 다음 1.5% HPMC 용액에 약 20초 침지한 후 튀김하여 만든 French-fried potato는 외국에서 수입하여 fast food chains에서 판매하는 제품과 유사한 텍스쳐 품질을 갖는 것으로 평가되었다.

유통 중인 스낵과자 104건에서 acrylamide함량조사 결과는 $236{\pm}322$ ppb로 측정되었으며 제품마다 차이가 크게 나타났다. 스낵과자는 그 원료에 따라 함량에 큰 차이를 나타내어 감자, 밀, 옥수수 순으로 측정되었고 감자스낵을 대상으로 국내산과 수입산의 함량을 조사한 결과 국내산이 약간 높게 측정되었다. 또한 패스트푸드점의 french fries 30건을 대상으로 측정한 acrylamide함량조사 결과는 $378{\pm}221$ ppb이었으며 제조회사별로 함량 차이가 크게 나타났다. French fries의 수분의 양과 acrylamide의 상관계수는 0.55이었고,지방 함량과의 상관계수는 0.25이었다. 제품의 저장에 따른 변화는 크지 않았으며 생산과정에서의 적절한 제조조건의 설정이 acrylamide 저감에 중요함을 알 수 있었다.

국내에서 시판되고 있는 감자 가공제품 12종류와 8가지의 다른 방법으로 조리한 감자 가공품의 potato glycoalkaloid(PGA)의 함량을 HPLC에 의하여 측정한 결과는 다음과 같다. 1. 조리 후 PGA의 감소는 물에 삶은 감자(91.68％)가 가장 많았고 다음으로는 물에 데친 감자(84.17％)였다. 기름에 튀긴 감자와 볶은 감자의 감소율은 각각 49.42％, 49.51％였으며 찐 감자는 50.52％로서 삶은 것에 비하여 감소율이 낮았으며 전자레인지에서 조리한 감자는 40.82％, 구운 것은 9.14％로서 가장 감소율이 낮았다. 증류수에 삶은 감자보다 1％ 소금물에 삶은 감자의 PGA가 낮은 감소율을 보였다. PGA 함량의 감소율이 높은 순서는 boiling 〉 blanching 〉 boiling with 2％ NaCl 〉 steaming 〉 sauteing 〉 frying 〉 microwaving 〉 baking 이었다. 2. 수입 감자로 만든 국내회사의 1종류 potato chip에서 PGA 69.57mg/100g 으로 가장 높은 함량을 보였으며 동일 브랜드의 국내산 감자로 만든 potato chip은 0.23mg/100g으로 미량이 함유되었다. 냉동 french fry용 감자에서는 미국산, 캐나다산의 수입 제품은 각각 PGA 5.54mg/100g, 6.45mg/100g 이었으나 국내산은 2.05mg/100g 였다. 국내 유명 fast food점 2곳에서 판매되고 있는 french fry 감자에는 PGA가 검출되지 않았다. Potato powder로 만든 과자류는 미국산 수입제품에서는 검출되지 않았고 국내사 2종류는 3.68mg/100g, 4.88mg/100g 의 함량을 보였다.

This study surveyed the Kimchi preference for French, potential Kimchi improvement for French market adaptation and Kimchi application for French cuisine, with the aim of spreading the recognition of Kimchi throughout the world, especially in France, by giving information and developing local types which could be expected to be suitable for utilization of French food life. The Kimchi experience of 100 persons in France was surveyed for the study. Most (72.0%) had no experience. For the preference of red Kimchi in palatable ripening period depending on sexes, women had a higher Score (M=4.04${\pm}$0.88) than men (M=3.91${\pm}$0.91) did. In the case of white Kimchi, women had a higher score (M=4.09${\pm}$0.90) than men (M=3.98${\pm}$1.01) did, also. The attraction reason of Kimchi for males was the chewing feel, healthy food and spicy taste, and for females was the chewing feel, spicy taste and healthy food orderly. However, the other side of the Kimchi improvement point was decreased fermented order, spicy taste and salinity, but improved orderly appearance. Thus, the Kimchi development point for French was keeping the crisp chewing feel, fermenting better at the fresh than ripening, reducing the fermented order and controlling the spice taste. Types of fermented food similar to Kimchi were involved in more than 80% of French cuisine, with the most common in the survey being pickled cabbage, followed by cabbage salary and fermented salted food orderly. The Kimchi utility as a raw ingredient or a seasoning for French cuisine was firstly as an accompaniment with meat cuisine, followed by appetizer, eating with cooked rice, eating with fish cuisine, orderly for males, whereas for females it was eating with cooked rice, followed by appetizer, eating with fish cuisine and eating with fried potato and orderly. Thus, the French had a similar view to Koreans regarding the accompaniment of Kimchi meat. The developed fusion Kimchi foods were 'Poitrine de porc caramelisee au miel et Kimchi', 'Blanc de barbue aux crevettes roses et Kimchii', 'Kimchi SpringRoll' and 'Potage saint-Germain aux Kimchi'. The French preference for Kimchi utility was generally a high score for the eating the cuisine in which Kimchi was added to meat cuisine.

BACKGROUND: Acrylamide (CAS No. 79-06-1) is known to be a carcinogenic compound, and is classified as a Group 2A compound by the International Agency for Research on Cancer (IARC, 1994). Acrylamide can be generated during the browning process via the non-enzymatic Maillard reaction of carbohydrates such as reducing sugars and of amino acids such as asparagine, both of which occur at a temperature above $120^{\circ}C$. Potato tubers contain reducing sugars, and thus, this will affect the safety of processed potato products such as potato chips and French fries. In order to reduce the level of acrylamide in potato processed products, it is therefore necessary to understand factors that affect the reducing sugar content of potatoes, such as environmental factors and potato storage conditions, as well as understanding factors affecting acrylamide formation during potato processing itself. METHODS AND RESULTS: Potatoes were cultivated in eight regions of Korea; For each of these different environments, soil physico-chemical characteristics such as pH, electrical conductivity, total nitrogen, available phosphate, and exchangeable cation content were measured and correlations with potato reducing sugar content and potato chip acrylamide levels were examined. The reducing sugar content in potato during storage for three months was determined and acrylamide level in potato chip was analyzed after processing. The storage temperature levels were $4^{\circ}C$, $8^{\circ}C$, or $10^{\circ}C$, respectively. The acrylamide content of chips prepared from potatoes stored at $10^{\circ}C$ or $20^{\circ}C$ for one month was analyzed and the different frying times were 2, 3, 5, and 7 min. CONCLUSION: This study showed that monitoring and controlling the phosphate content within a potato field should be sufficient to avoid producing brown or black potato chips. For potatoes stored at low temperatures, a reconditioning period ($20^{\circ}C$ for 20 days) is required in order to reduce the levels of reducing sugars in the potato and subsequently reduce the acrylamide and improve chip coloration and appearance.

대두유를 튀김유로 사용하여 french fried potato를 $185^{\circ}C$에서 제조하면서, 1일 7시간씩 총 56시간동안 가열 및 튀김후 composited powder (citric acid, 물, rhyolite 혼합물)를 처리한 대두유와 처리하지 않은 대두유의 기능성, 발연점, 기포성 및 점도와 물리화학적 성질을 비교 분석하였다. Composited powder를 처리하면 극성지질의 생성을 억제하고, 불포화 지방산의 가열산패를 억제시켜, 튀김유의 수명을 약 50% 증가시켰음을 확인하였다. 그러나 산가증가의 억제 및 발연점 저하의 효과가 없었다.

This study investigated the preference and intake frequency of a list of 15 commonly available high sodium Malaysian foods/dishes, dis cretionary salt use, and their possible association with demographics, blood pressures and anthropometric measurements among 300 Malaysian university students (114 males, 186 females; 259 ethnic Chinese, 41 Indians; 220 lean, 80 overweight). French fries and instant soup noodle were found to be the most preferred and most frequently consumed salty food, respectively, while salted fish was least preferred and least frequently consumed. Males had a significantly higher intake frequency of at least 6 of the salty foods, but the preference of most salty foods was not significantly different between genders. Ethnic Chinese significantly preferred more and took more frequently traditional and conventional Malaysian foods like asam laksa (a Malaysian salty-sour-spicy noodle in fish stock), salted biscuits and salted vegetable, while Indians have more affinity and frequency towards eating salty Western foods. Body Mass Index was significantly negatively correlated with the intake frequency of canned/packet soup and salted fish while waist circumference was significantly positively correlated with the preference of instant noodle. Also, an increased preference of potato chips and intake frequency of salted biscuits seemed to lead to a decreased WHR. Other than these, all the other overweight/obesity indicators did not seem to fully correlate with the salty food preference and intake frequency. Nevertheless, the preference and intake frequency of asam laksa seemed to be significant negative predictors for blood pressures. Finally, increased preference and intake frequency of high sodium shrimp paste (belacan)-based foods like asam laksa and belacan fried rice seemed to discourage discretionary salt use. In conclusion, the preference and intake frequency of the high sodium belacan-based dish asam laksa seems to be a good predictor for ethnic difference, discretionary salt use and blood pressures.
