Yuzu (Citrus junos) undergoes traditional processing to create preserved yuzu with a sugar content of 50%. This study aimed to produce low-sugar yuzu syrup using artificial or natural sweeteners instead of sugar. Among artificial sweeteners, maltitol showed minimal browning and lack of deposition at high temperatures. The addition of xanthan gum (0.2%) and carboxymethyl cellulose (0.2%) resolved the issue of layer separation and viscosity decrease of yuzu syrup. Alternatively, grain syrup, a natural sweetener, improved viscosity and homogeneity without the additives. Yuzu syrups were developed using yuzu juice and preserved yuzu, with maltitol (20~40%) or grain syrup (50~70%) as the sweetener. Yuzu syrups containing 35% maltitol (M35) or 55% grain syrup (G55) had less than 5% and 10% free sugar, respectively. These syrups exhibited taste patterns similar to commercial yuzu syrup in analysis using an electronic tongue. Furthermore, M35 and G55 contained yuzu flavonoids at concentrations of 19.82 mg/g and 24.09 mg/g, respectively. Antioxidant activity (DPPH, ABTS radical scavenging) of M35 and G55 was equivalent to 10.55, 17.59 mg/100 g of Vitamin C and 97.39, 33.92 mg/100 g of Vitamin C, respectively. Consequently, M35 and G55 offer promising alternatives to preserved yuzu, providing low-sugar yuzu syrups enriched with functional ingredients.

Dental caries is the first disease to cause the pathological extraction of teeth in children. The complete prevention of dental caries is not achieved by toothbrushing alone. The use of fluoride and pit and fissure sealant is regarded as key tools to prevent dental caries. Fluoride-containing tablets or multi-vitamins and community water fluoridation can be used as systemic application techniques. Professional fluoride application, fluoride iontophoresis on teeth, fluoride mouth rinsing and fluoride-containing toothpaste can be used as local application techniques. Pit and fissure sealant is mainly used to prevent dental caries on occlusal surfaces of premolars and molars. Sweeteners not to occur dental caries has been developed to substitute sucrose. Dental erosion increases according to the high consumption of acidic soft drink or beverages. The appropriate use of fluoride and pit and fissure sealant are recommended to prevent dental caries effectively and the education is required to reduce the consumption of acidic soft drinks or beverages to decrease dental erosion.

The objectives of this study was to investigate the sensory and quality characteristics of Solsulgi made from rice flour and glutinous rice flour containing 1, 2, or 3% of pine leaves powder. The results of sensory evaluation showed that Solsulgi containing 1% pine leaves powder had high overall acceptability, chewiness and sweetness preference. In the results of textural analysis, the hardness was decreased by adding pine leaves powder. Hunter color L-value of Solsulgi decreased by increasing the level of pine leaves powder. The more pine leaves powder was added, the a-value and b-value of Solsulei were decreased. The moisture content was higher in Solsulgi with sugar than honey and oligo-saccharide.

Stevioside, a natural sweeteners presently used in various kinds of food and food products in Korea, was evaluated for its toxicity potential in the 14 day feeding study using B6C3F1 mice. Stevioside was added to the diet at different concentrations of 0.31, 0.62, 1.25, 2.5 and 5%, and was administered for 14 consecutive days. An increase of liver organ weight in male mice was observed. No diet-related differences were noted in clinical signs, food consumption, and gross and histopatholgical evaluation. Based on these results, we concluded that the concentration of 5% in the diet was a suitable maximum tolerable dose of stevioside for a 90 day study in mice.

A sweet protein monellin was originally isolated from the berries of the West African plant Dioscoreophyllum cumminsii. The studies for molecular interaction of different sweeteners with receptor as well as receptor binding model have been proposed previously. The high-resolution solution structure of single-chain monellin (SCM) has been determined to investigate structural origin of sweet taste by NMR spectroscopy and simulated annealing calculations.(omitted)

Novel food materials can be produced based on biotechnology such as genetic recombination, microbial fermentation, and enzymatic engineering by utilizing living organisms such as animal, plant, and microorganism or by applying the enzymes isolated from them. Especially, exploration and development of novel prebiotics and probiotics attracted great attention worldwide in the food industry, of which the research and industrial trends in food biotechnology field are promoting the production of next generation sweeteners and proliferation of beneficial bacteria in gastrointestinal tract. Development and commercialization of novel food materials by domestic bioprocessing technology have been sluggish due to the GMO/LMO food safety issues. Meanwhile, the US and EU do not perceive badly about gene manipulation technology, and the research is most active in the fields of crops and GMMs, respectively. Genetic scissors, which are considered as next generation technology, are notable since foreign genes do not remain in final products.
