Optimization of accelerated solvent extraction of ellagitannins in black raspberry seeds using artificial neural network coupled with genetic algorithm
출판일자. 202212 Abstract This study aimed to identify ellagitannins in black raspberry seeds (BRS) and to optimize accelerated solvent extraction of ellagitannins using an artificial neural network (ANN) coupled with genetic algorithm. Fifteen monomeric and dimeric ellagitannins were identified in BRS. For ANN modeling, extraction time, extraction temperature, and solvent concentration were set as input […]
γ-Aminobutyric acid and oxalic acid contents and angiotensin-converting enzyme inhibitory activity of spinach juicescofermented withLevilactobacillus brevisGABA100 and otherlactic acid bacteria
출판일자. 202210 Abstract This study aimed to develop fermented spinach juice with enhancedγ-aminobutyric acid (GABA) leveland angiotensin-converting enzyme (ACE) inhibitory activity and reduced oxalic acid level. We cofer-mented spinach juice withLevilactobacillus brevisGABA100 and oxalic acid-degrading bacteria (Lacto-bacillus gasseriHHuMin D,Lactobacillus sakeiRH1114,Lactobacillus acidophilus19L5, orLimosilactobacillus fermentumBH03). GABA levels were not different among all the fermented juicesexcept for the […]
Wheat gluten hydrolysates prepared by sequential treatment with different combinations of commercial proteases
출판일자. 202210 Abstract This study aimed to develop wheat gluten hydrolysates (WGH) prepared by sequential enzymatic hydrolysis for its application in commercial beverage. The hydrolysis of WGH was performed with different combinations of commercial endo-proteases (Alcalase, A; Neutrase, N; and Protamex, P) and Flavourzyme (F) under limited hydrolysis conditions. The WGH sequentially hydrolyzed with A […]
Black raspberry extract can lower serum LDL cholesterol via modulation of gut microbial composition and serum bile acid profile in rats fed trimethylamine-N-oxide with a high-fat diet
출판일자. 202207 Abstract Blood trimethylamine-N-oxide (TMAO) has been associated with cardiovascular disease. Black raspberry (Rubus occidentalis, BR) has been regarded to be beneficial for cardiovascular health. This study aimed to investigate how BR extract affects serum lipid profile, gut microbial composition, metabolites in rats fed TMAO with a high-fat diet. Dietary TMAO increased serum LDL […]
Antibacterial effect of cell-free supernatant fraction from Lactobacillus paracasei CH88 against Gardnerella vaginalis
출판일자. 202203 Abstract Bacterial vaginosis (BV) is the most common vaginal infection in reproductive women, which is characterized by depleted level of lactic acid bacteria and overgrowth of anaerobes such as Gardnerella vaginalis spp. Lactic acid bacteria have been known to be beneficial for amelioration of BV, since they produce antimicrobial substances against G. vaginalis spp. The objectives of […]
Phenolics in buckwheat hull extracts and their antioxidant activities on bulk oil and emulsions
출판일자. 202207 Abstract Buckwheat hulls are discarded as waste, although they have more phenolic compounds than buckwheat groats. The antioxidant activities of buckwheat hull extracts prepared with water, 50% ethanol, and 100% ethanol were investigated in bulk oil, oil-in-water (O/W), and water-in-oil (W/O) emulsions. The relationship between the phenolic compositions of the extracts and their […]
Physicochemical characteristics and sensory acceptability of crackers containing red ginseng marc
출판일자. 202201 Abstract Red ginseng marc (RGM), a by-product from ginseng industry, still contains bioactive compounds such as ginsenosides and dietary fibers. The objective of this study was to investigate effects of baking conditions and formulations on physicochemical and sensory characteristics of crackers in which RGM was incorporated. The sum of ginsenoside Rb1, Rg1 and […]
Exploration of an effective method to determine the relative sweetness of natural alternative sweeteners: Comparison of two-alternative forced-choice test and generalized labeled magnitude scale
출판일자. 202202 Abstract The relative sweetness (RS) of natural alternative sweeteners is influenced by their distinct flavors and temporal profiles but also by the determination method. This study investigated the reported RS of natural alternative sweeteners using two methods-the two-alternative forced-choice (2-AFC) test and generalized labeled magnitude scale (g-LMS). The 2-AFC test and g-LMS were […]
Sweetness profiles of glycosyl rebaudioside A and binary mixtures with sugar alcohols in aqueous solution and a lemonade model system
출판일자. 202203 Abstract BACKGROUND The demands for better-tasting alternative sweeteners have driven efforts to improve the sensory properties of rebaudioside A (Reb-A), such as glycosylation and blending with bulk sweeteners. This study attempted to (i) investigate the sensory profiles of a novel sweetener, glycosyl rebaudioside A (gReb-A), and its 1:1 mixtures with erythritol or maltitol, […]
Consumers better explained drivers of liking for products containing complex flavor with subtle differences than trained panelists: Comparison between consumer-driven free-comment analysis and descriptive analysis of tomato sauce with added garlic flavorings
출판일자. 202206 Abstract Owing to difficulties associated with profiling and differentiation, it is challenging to identify drivers of liking of samples that contain complex flavor but have subtle differences. This study compared the efficacy of free-comment (FC) analysis with descriptive analysis (DA) for profiling the sensory characteristics of tomato sauce with added garlic flavoring to […]
