The rising prevalence of obesity and diabetes is a significant health concern both in globally and is now regarded as a worldwide epidemic. Added sugars like sucrose and high-fructose corn syrup (HFCS) are a major concern due to their link with an increased incidence of diet-induced obesity and diabetes. The purpose of this review is to provide insight into the effects of natural sweeteners as alternatives to sucrose and HFCS, which are known to have negative impacts on metabolic diseases and to promote further research on sugar consumption with a focus on improving metabolic health. The collective evidences suggest that natural alternative sweeteners have positive impacts on various markers associated with obesity and diabetes, including body weight gain, hepatic fat accumulation, abnormal blood glucose or lipid homeostasis, and insulin resistance. Taken together, natural alternative sweeteners can be useful substitutes to decrease the risk of obesity and diabetes compared with sucrose and HFCS.

Cariogenicity of the bacteria is attributed to their binding capacity to the teeth. Bacterial attachment to oral surfaces is an essential step for colonization and subsequently infection. Therefore, it is conceivable that caries prevention can be achieved fundamentally by inhibition of bacterial attachment. The rationale for caries prevention through the use of sugar substitutes or limited use of sugar has been revealed. Among many sugar substitutes, xylitol has been shown to exhibit the most profound cariostatic effect, inhibiting glucose metabolism and possibly binding of mutans streptococci. The purpose of this study was to examine the effect of xylitol on binding of different species of oral bacteria. The effect of xylitol on binding of [$^3H$]-labeled oral bacteria to hydroxyapatite coated with human saliva(SHA) as a model for the pellicle-coated tooth surfaces was investigated. The strains of oral bacteria used in this study were A. viscosus T14V, A. viscosus WVU627, P. gingivaiis 2561, P. gingivalis A7Al-28, S. gordonii G9B, S. gordonii Challis, S. sobrinus 6715, S. mutans UA101, S. mutans KPSK -2, S. mutans T8, and S. mutans UA130. The obtained results were as follows: 1. P. gingivalis A7 Al-28, S. mutans UA130, S. mutans T8 grown with xylitol showed greater binding to SHA than the organism grown without xylitol. Among these, S. mutans T8 showed the greatest rate of increase in its binding to SHA ; 8-fold increase in its binding with xylitol. 2. S. mutans KPSK -2 grown with xylitol showed 2 times lesser binding to SHA than the organism grown without xylitol. 3. Binding ability of the remaining strains grown with xylitol to SHA was almost same as that of the organisms grown without xylitol. The overall results suggest that use of xylitol in the oral cavity may affect the complex oral bacterial ecosystem.

Despite the emergence of obesity as a significant public health concern, artificial sweeteners have made their way into various food products due to the perception, that they serve as substitutes for sugar. Artificial sweeteners are used to supposedly achieve weight management and health improvement. However, their efficacy and safety remain debatable. Commonly used artificial sweeteners include aspartame, acesulfame potassium, saccharin, and sucralose. This article discusses the effects of artificial sweetener consumption on weight loss, appetite regulation, blood glucose control, and gut microbiota. Research findings, concerning the consumption of artificial sweeteners and their association with body weight, have shown inconsistencies between randomized controlled trials and cohort studies. Studies, comparing artificial sweeteners to sugar, have reported no significant differences in satiety. Although artificial sweeteners have no calories, they can affect blood sugar levels through the cephalic phase insulin response. A recent study suggested that artificial sweeteners influenced the occurrence of diabetes. Due to limitations in the study design, excluding diabetes-influencing factors was not feasible. The evidence showed that artificial sweeteners harbored potential health risks, necessitating further investigation. According to recent studies, the consumption of artificial sweeteners was associated with gut microbiota changes and individual blood sugar responses. It is important to note that artificial sweeteners cannot be considered safe alternatives to sugar, and further research is required.

This study was conducted to determine the quality characteristics of grape jellies for the elderly. The jellies contained sugar (control) or sugar derivative sweeteners (erythritol, isomaltooligosaccharide, sorbitol, and xylitol). Agar (0.31%) and $\kappa$-carrageenan (0.27%) were the gelling agents. The average age of the subjects participating in the acceptance test was 79. The lightness (L), redness (a), and yellowness (b) values of the agar gel with erythritol mostly decreased, indicating a darker and pale red color. The L and b values of the carrageenan gel with sugar derivative sweeteners increased, indicating brighter and yellowish color. The agar and carrageenan gels with sorbitol showed higher gelling and melting temperature, indicating that gelation occurred easily and did not easily melt. The agar and carrageenan gels with xylitol showed a low-melting temperature, indicating low stability with temperature change. The break-down rate of the agar and carrageenan gels with erythritol was low, whereas that of agar gel with sorbitol was relatively high despite its high melting temperature. Hardness, cohesiveness, gumminess, and chewiness of the gels with sugar derivative sweeteners decreased, and this tendency was most distinct with isomaltooligosaccharide in the agar gel and with sorbitol in the carrageenan gel. The rupture properties of the gel were the same as the hardness of the gel. Sensory acceptance of the agar gels with erythritol, sorbitol, isomaltooligosaccharide, and the carrageenan gel with erythritol was fairly high, whereas that of the agar gel with xylitol and the carrageenan gel with isomaltooligosaccharide and xylitol was low. The results show that sorbitol and erythritol are appropriate as sugar substitutes in grape jellies for the elderly about the acceptability and stability of the gels.

설탕 및 다양한 대체감미료를 사용하여 제조한 백설기의 품질 특성을 평가함으로써, 대체감미료의 사용이 백설기의 이화학적 관능적 특성 및 저장 중 경도 변화에 미치는 영향을 평가하였다. 관능검사를 통해 개별 감미료의 상대당도를 결정한 후, 10% 설탕과 동일한 단맛을 주는 감미료의 양을 백설기 제조에 사용하였다. 제조된 백설기들은 완성 직후 수분함량에서는 유의적 차이를 나타내지 않았다. 그러나, 설탕 첨가군에 비해 아스파탐 첨가 백설기는 유의적으로 낮은 pH를 나타내었고, 포도당 첨가 백설기는 옅은 황색을 띄어 낮은 명도를 나타내었다. 이러한 차이는 각각 아스파탐 및 그 분해산물의 낮은 pKa값과 포도당에 의한 갈변 반응의 결과로 해석되었다. 제조 직후 실시한 기계적 물성 평가 결과는, 백설기 물성 결정의 주요 요인인 전분의 호화 및 팽윤 정도가 설탕 및 대체감미료로 제조된 7종의 백설기 사이에서 유의적 차이가 없었음을 시사하였다. 그러나, 저장 시간의 경과에 따른 백설기의 물성을 평가한 실험에서는, 에리스리톨과 수크랄로스 첨가 백설기들이 당류 및 자일리톨 첨가군들에 비해 경도가 큰 폭으로 증가하는 현상이 관찰되었다. 이는, 저장 중 백설기의 수분함량 변화보다는 두 감미료 자체의 흡습이 어려운 물성의 결과로 해석되었다. 한편, 관능검사 결과, 수크랄로스와 자일리톨 첨가 백설기는 평가된 모든 관능적 특성들에서 설탕 첨가군과 유의적 차이를 나타내지 않아 가장 높은 기호도를 지닌 것으로 평가되었다. 저장 기간에 따른 물성 변화의 결과를 함께 고려하면, 자일리톨 첨가 백설기가 설탕 첨가 백설기와 이화학적 관능적 특성에서 가장 유사한 결과를 보임으로써, 백설기 제조에 있어 대체 가능성이 높은 것으로 평가되었다.

Some sensory properties of synthetic sweeteners are limiting factors for use in low calorie foods of soft drinks. By combining synthetic sweeteners(Neohesperidin dihydrochacone(NHDC), stevioside) with sucrose, sorbitol or xylitol, these limitations can be overcome. Using trained taste panelists and magnitude estimation methods, synergistic effects were investigated in binary sweetener mixtures, The results showed that synergism, as much as 28% to 69%,was noted at all concentration in xylitol-stevioside, NHDC-stevioside mixtures. Synergistic effects were found only at high concentration levels in mixtures of sucrose-NHDC, sucrose-stevioside, and sorbitol-stevioside, ranging from 11% to 22%.By taking advantage of synergistic effects, ginseng tea and orange flavored beverages, sweetened with either xylitol-stevioside of NHDC-stevioside, were prepared and the sensory quality was compared with that of sucrose containing beverages. It was found that sensory characteristics were judged to be very similar for all formulations. The result suggests the possibility of using of using these sweetener mixtures as sugar substitutes in ginseng tea and orange drink.

Beer production with rice or other malt substitutes suffers from a lack of suitable enzymes for saccharification. For this reason, rice nuruk (fermentation starter) was tested as a starch replacement for malt in the saccharification process of beer production. The results of this study show that the enzyme activities of rice nuruk made with brewing fungi were higher than those of malt. Saccharification and glucoamylase activities were high in Aspergillus awamori KCCM 30790 and α-amylase activity was high in Aspergillus oryzae CF1003. Overall, malt beer had significantly higher alcohol, pH, total acid, volatile acids, amino acids, free amino nitrogen, bitterness unit and ΔE than rice nuruk beer. Where as Aspergillus awamori KCCM 30790 beer had significantly higher soluble solids, reducing sugar than malt beer. According to a sensory evaluation, malt beer was better color, flavor and Aspergillus oryzae CF1003 beer was better taste, texture, overall acceptability than other beer. Therefore Aspergillus awamori KCCM 30790 beer was suitable considering enzyme activities (saccharification, glucoalmylase) and physicochemical characteristics (soluble solids, reducing sugar). And then Aspergillus oryzae CF1003 beer was suitable considering sensory evaluation (taste, texture, overall acceptability). Therefore rice nuruk like Aspergillus awamori KCCM 30790 and Aspergillus oryzae CF1003 were suitable as a substitute material that can replace for malt in beer proceccing.

The use of low-cost substrates represents one key issue to make single cell oil production sustainable. Among low-input crops, Arundo donax L. is a perennial herbaceous rhizomatous grass containing both C5 and C6 carbohydrates. The scope of the present work was to investigate and optimize the production of lipids by the oleaginous yeast Cutaneotrichosporon curvatus from undetoxified lignocellulosic hydrolysates of steam-pretreated A. donax. The growth of C. curvatus was first optimized in synthetic media, similar in terms of sugar concentration to hydrolysates, by applying the response surface methodology (RSM) analysis. Then the bioconversion of undetoxified hydrolysates was investigated. A fed-batch process for the fermentation of A. donax hydrolysates was finally implemented in a 2-L bioreactor. Under optimized conditions, the total lipid content was 64% of the dry cell weight and the lipid yield was 63% of the theoretical. The fatty acid profile of C. curvatus triglycerides contained 27% palmitic acid, 33% oleic acid and 32% linoleic acid. These results proved the potential of lipid production from A. donax, which is particularly important for their consideration as substitutes for vegetable oils in many applications such as biodiesel or bioplastics.
