The purpose of this study was to investigate the quality of sugar-snap cookies containing various types and mixture ratios of sugar. The characteristics of sugar-snap cookies prepared with fructose, high-fructose corn syrup and invert sugar were examined through physical properties measurement and sensory evaluation. Results of the investigation suggest significant differences in the cookies made with various sugars. High-fructose corn syrup was better than others for making sugar-snap cookies. The quality of cookies baked with high-fructose corn syrup was improved compared to cookies baked with invert sugar or fructose. Varying the formula, with high-fructose corn syrup had little or no effect on the quality of the final product. Using different quantities of invert sugar and high-fructose corn syrup significantly affected the physical properties of the cookies. Sugar-snap cookies containing invert sugar had an extremely positive effect.

The global consumption of fructose in the form of high-fructose corn syrup (HFCS) has increased considerably over the past several decades. The current intake of HFCS exceeds that of other major caloric sweeteners such as sucrose. Fructose has potentially adverse effects on human metabolism. Therefore, the objective of this study was to analyze the monosaccharide contents of 13 sweetened milk-based beverages by using high-performance liquid chromatography (HPLC). The total monosaccharide (fructose and glucose) contents of various sweetened milk-based beverages ranged from 0.60 g/100 mL (cheese) to 26.03 g/100 mL (maple caramel snack), while milk showed only 0 g/100 mL monosaccharides. The fructose-to-glucose ratio of various popular sweetened milk-based beverages ranged from not-detected (ND) to 2.24 g/100 mL, but the content of glucose was higher than that of fructose in only three samples, namely, strawberry flavored milk, shrimp chips, and maple caramel snack. The analyzed results revealed important basic information about monosaccharides in various milk-based sweetened beverages, presenting ideas for future fructose research.

A Novel Production Method for High-Fructose Glucose Syrup from Sucrose-Containing Biomass by a Newly Isolated Strain of Osmotolerant Meyerozyma guilliermondii

( Sadat Mohammad Rezq Khattab ),( Tsutomu Kodaki ) 한국미생물 · 생명공학회 2016 Journal of microbiology and biotechnology Vol.26 No.4

One osmotolerant strain from among 44 yeast isolates was selected based on its growth abilities in media containing high concentrations of sucrose. This selected strain, named SKENNY, was identified as Meyerozyma guilliermondii by sequencing the internal transcribed spacer regions and partial D1/D2 large-subunit domains of the 26S ribosomal RNA. SK-ENNY was utilized to produce high-fructose glucose syrup (HFGS) from sucrose-containing biomass. Conversion rates to HFGS from 310-610 g/l of pure sucrose and from 75-310 g/l of sugar beet molasses were 73.5-94.1% and 76.2-91.1%, respectively. In the syrups produced, fructose yields were 89.4-100% and 96.5-100% and glucose yields were 57.6-82.5% and 55.3-79.5% of the theoretical values for pure sucrose and molasses sugars, respectively. This is the first report of employing M. guilliermondii for production of HFGS from sucrose-containing biomass.

On June 13, 2013., The Japan Fair Trade Commission (JFTC) issued cease and desist orders and surcharge payment orders to manufacturers of specific high-fructose corn syrup (HFCS) and manufactures of specific starch syrup and glucose, finding that they substantially restrained competition in the fields of selling the specific HFCS and specific starch syrup and glucose, in concert with one another, by concluding agreements, at the latest by December 28, 2010, to raise the selling prices of specific HFCS and specific starch syrup and glucose. The aggregated amount of the surcharges ordered is 2,572.45 million yen. Before issuing the cease and desist orders and the surcharge payment orders, the JFTC notified the said enterprises of the contents of the planned orders and provided them with opportunities to present their opinions and submit evidence. The JFTC issued the orders taking the opinions and the evidence submitted into consideration. The recipients dissatisfied with the orders may request, within sixty days of the date on which the transcript of the orders were served, the JFTC to initiate hearing procedures regarding the orders. On January 13, 2017., a panel of the Tokyo High Court stayed the enforcement of the JFTC’s cease and desist order. The Tpanel of the Tokyo High Court judged a meeting to place an increase of the selling price on the Nihon Keizai Shimbun, and exchange information on the level of the increase amount there. Furthermore, after posting an article on the increase outlook in the Nihon Keizai Shimbun, information exchange was held on the progress of price negotiations. It is recognized that there is "meeting of minds" about price increase from such fact. 일본 公正取引委員會는 2013년 6월 13일, 가토화학주식회사(加藤化学株式会社, 이하 「X」라 한다)등에 대하여, 특정이성화당 및 특정물엿・포도당에 대하여 가격담합을 하였다고 하여, 배제조치명령 및 과징금납부명령을 하였다.

생전분의 고농도 무증자당화법을 도입한 새로운 High Fructose Corn Syrup 제조공정

박동찬,이용현 한국산업미생물학회 1992 한국미생물·생명공학회지 Vol.20 No.4

분쇄마찰매체함유 불균일상 효소반응계를 활용한 생전분의 무증자당화법은 고농도, 고순도의 포도당를 고효율로 직접 얻을 수 있는 새로운 당화법으로 이를 high fructose corn syrup(HFCS) 제조공정에 응용코져 연구하였다. 400g/ℓ 생전분을 24시간 무증자당화시켜 이성화반응에 적합한 고농도인 398g/ℓ와 고순도인 98% 포도당 용액을 농축과정을 거치지 않고 직접 얻을 수 있었다. 전분에 대한 포도당수율은 0.90으로, 미반응 잔유전분은 쉽게 원심분리되었으며, 재당화도 용이하였다. 또한 무증자당화액은 단백질성 변성물, 이온 등 불순물의 함량이 매우 적어, 이성화 반응 전단계인 분리 정제과정을 단순화할 수 있었다. 생성된 당용액의 고정화 포도당 이성화효소 기질로서의 적합성을 검토하여 우수한 결과를 얻었다. 생전분 직접당화법을 도입한 새로운 HFCS 제조공정은 액화/당화공정을 경유하는 기존의 공정에 비하여 여러가지 장점이 있어 산업적 활용이 기대되며, 이를 위한 후속연구가 요망된다. An innovative process for high fructose corn syrup (HFCS) production coupled with direct saccharification of raw corn starch in the agitated bead enzyme reactor (bioattitor) was investigated. The required high concentration/purity of glucose solution suitable for isomerization was produced directly in a bioattritor, without condensation of hydrolyzate, 398g glucose/ℓ and 98% glucose content from 400 g/ℓ(w/v) of raw corn starch after 24 hours. The unsaccharified residual starch could be separated easily upon centrifugation, and resaccharified. The obtained solution also possessed other desirable requirements as substrate for isomerization, such as, low concentrations of denatured protein and calcium ions, thereby, simplified the purification step. The obtained glucose solution was isomerized in an enzyme reactor paked with immobilized glucose isomerase to evaluate the suitability as a substrate. The proposed new HFCS process seems to have many advantages over the conventional process via liquefaction-saccharification steps. The follow-up investigations of the proposed process need to be conducted to evaluate the feasibility of industrial application.

총설 : 액상과당의 영양대사학적 특성과 건강에 미치는 영향

김혜미 ( Hyemi Kim ),정정호 ( Jeongho Jeong ),고광웅 ( Gwang Woong Go ) 한국산업식품공학회 2015 산업 식품공학 Vol.19 No.2

High fructose corn syrup (HFCS) is a liquid sweetener of glucose-fructose monomer mixture, commonly known as replacement for sucrose (table sugar). HFCS was first applied to food companies in the early 1970s ever since there was a huge increase of its use worldwide, especially in beverage and processed food. While the metabolic and nutritional characteristics of HFCS have been widely studied, only recently has the role of HFCS in metabolic syndrome and other health issues emerged. Studies in many laboratories worldwide have built the evidence that excessive consumption of HFCS plays a crucial role in insulin resistance, dyslipidemia, obesity, hypertension, and kidney disease. This manuscript reviews the history, manufacturing process, and nutritional and metabolic traits of HFCS and describes its involvement in the pathogenesis of metabolic syndromes and obesity.
