Historically, fish sauce has been a standard condiment and ingredient in various Southeast Asian cuisines. Moreover, fish sauce imparts umami taste, which may enhance perceived saltiness in food. This quality suggests that fish sauce may be used as a partial substitute for sodium chloride (NaCl) in food preparation, which may present a valuable option for health‐conscious and salt‐restricted consumers. However, the degree to which NaCl can be decreased in food products without compromising taste and consumer acceptance has not been determined. We hypothesized that NaCl content in food may be reduced by partial replacement with fish sauce without diminishing palatability and consumer acceptance. Preparations of 3 types of food were assessed to test this hypothesis: chicken broth (n = 72); tomato sauce (n = 73); and coconut curry (n = 70). In the first session, the percentage of NaCl that could be replaced with fish sauce without a significant change in overall taste intensity was determined for each type of food using the 2‐Alternative Forced Choice method. In the second session, subjects rated 5 samples for each food with varying NaCl and/or fish sauce content on 3 sensory attributes: deliciousness; taste intensity; and saltiness. Our results demonstrate that NaCl reduction was possible in chicken broth, tomato sauce, and coconut curry at 25%, 16%, and 10%, respectively, without a significant loss (P < 0.05) in deliciousness and overall taste intensity. These results suggest that it is possible to replace NaCl in foods with fish sauce without reducing overall taste intensity and consumer acceptance.  相似文献

Milk with an increased content of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and conjugated linoleic acid (CLA) was obtained by incorporating fish oil into the feed of cows. The 4 feed treatments used were a control diet of 57% forage and 43% concentrate mix with EnerGII fat supplement at 1.65% of dietary DM, or EnerGII in the basal diet was partially replaced with 1) 0.21% partially ruminally inert calcium salts of 71% fish oil given at 0.41% of DM; 2) 0.41% inert calcium salts of 71% fish oil given at 0.83% of DM; or 3) 0.83% inert calcium salts of 43% fish oil given at 0.83% of DM. The cows were milked after 5 and 8 wk and the EPA, DHA, and CLA contents in the pasteurized whole milk were determined. The presence of off-flavors in the milk was investigated after 3 and 10 d of storage. Twelve judges were trained to evaluate the presence of grassy, fishy, oily, oxidized, and rancid off-flavors. Although levels of EPA, DHA, vaccenic acid, and CLA increased for all 4 treatments, a trained sensory panel detected no difference in milk flavor between treatments and the control, with little or no intensity of off-flavors. Results suggest that feeding fish oil and EnerGII at varying levels enhanced CLA, EPA, DHA, and total n-3 fatty acids in milk over the length of the experiment without negatively affecting milk flavor. This creates the potential for a more marketable and healthful product.  相似文献

A traditional Japanese umami‐rich stock, dried bonito stock, was reported to improve the palatability of a low‐salt diet due to its characteristic aroma. Two pathways are available for the presentation of odors: the orthonasal and retronasal pathways. Aroma is perceived through the orthonasal pathway. In contrast, retronasal application of odors is thought to evoke different sensations from the orthonasal pathway, which is typically perceived as taste and modifies taste. Therefore, the effect of retronasal odor on salt‐reduction might be different from that of aroma, that is, orthonasal odor. Thus, the effects of the retronasal odor of dried bonito stock on the enhancement and improvement of palatability upon salt reduction were examined using sensory evaluation. Moreover, the contributions to flavor expression and palatability of dried bonito stock were also investigated. Although the retronasal odor of dried bonito did not enhance saltiness, it improved the palatability of saltiness. In the presence of no tastants except 0.68% NaCl, a content 15% less than that of Japanese traditional soup, the retronasal odor of dried bonito generated umami, enhanced the suitability for dried bonito stock, and increased palatability. This indicates that the retronasal odor of dried bonito stock could improve the palatability of a salt‐reduced diet. These findings can be applied to the development of new seasonings for improving the palatability of salt‐reduced foods.  相似文献

本文采用感官评价和电子舌技术相结合的方式,对鱼露中分离鉴定后进行固相合成的两种肽Gly-Pro和Val-Hyp的单体呈味和二肽与谷氨酸钠、氯化钠相互作用的呈味特性进行研究。结果表明,在单体呈味分析中,Gly-Pro具有鲜味和浓厚感,Val-Hyp具有鲜味且鲜味较持久和轻微浓厚感;在相互作用分析中,Gly-Pro降低了谷氨酸钠的鲜味,Val-Hyp对谷氨酸钠呈味无明显影响。Val-Hyp与氯化钠有显著协同作用,且溶液整体有厚味,而Gly-Pro与氯化钠没有协同作用,反而抑制咸味,但口感丰富。由此可得,鱼露中Gly-Pro和Val-Hyp的呈鲜特性的研究结果表明了其对鱼露鲜美味感具有一定贡献。  相似文献

ABSTRACT: A bacterium, which was isolated from fish-sauce mush (moromi) of frigate mackerel and identified as Staphylococcus xylosus , could change notes of an odor in fish sauce made in Thailand. Volatile compounds of the fish sauce after incubation at 32 °C for 24 d with the cultured bacterium were analyzed by gas chromatogra-phy. Although the contents of 2-ethylpyridine and dimethyl trisulfide were reduced during the incubation, 4 volatile compounds, including 2-methylpronal, 2-methylbutanal, 2-pentanone, and 3-(methylthio)propanal, showed no significant quantity changes. On the other hand, although 3-methyl-1-butanol and 2,6-dimethylpyrazine were markedly increased, 3-methylbutanoic acid was slightly increased. As a result of sensory evaluation, fishy, sweaty, fecal, and rancid notes of the fish sauce treated with the bacterium were all weaker than those of the nontreated fish sauce. No changes were found with respect to burnt, cheesy, meaty, and ammoniacal notes between fish sauce treated with the bacterium and that without treatment. Taken together, the odor of fish sauce was much improved by treatment with the isolated bacterium.  相似文献

Flavor and texture profiles of the cooked flesh of selected freshwater fish in retail distribution were developed by a highly trained sensory panel. The intensity of a variety of flavor, aftertaste, and texture properties was characterized for each fish, including order of appearance for flavor characteristics. These data provide a first examination of the sensory properties of a variety of freshwater fish available to the consumer. A variety of species, including tilapia and hybrid bass, had overall fish-like flavor and texture, but also had some properties similar to white meats, such as chicken. Catfish was earthier, softer, and more gelatinous than most other freshwater fish studied.  相似文献

该研究分析了市售常见海鲜调味汁风味特性的差异,应用气相离子迁移谱(GC-IMS)、智鼻、智舌技术研究其风味特点,结合游离氨基酸分析和感官评价员的量化描述(QDA)评分,进行主成分分析和对比鉴别。乙酸乙酯在5种海鲜酱油样品中含量较高峰强度值均在6 700以上,乙酸乙酯在特级鱼露中的峰强度为566.73,在上等蚝油中的峰强度值为80.71。海鲜酱油样品中苯乙醛和异戊醇含量也较高,峰强度数值均在1 700以上。海鲜调味汁中的糠醛含量则无显著规律。海鲜味酱油中的总游离氨基酸含量最高,为0.143 nmol/μL,上等蚝油的总鲜味氨基酸含量最高,其中谷氨酸占总鲜味氨基酸总量的99.82%。电子鼻和电子舌能高效判别海鲜调味汁的气味和滋味差异,GC-IMS能快速筛选关键特征气味化合物。电子舌分析结果和QDA结果有高度一致性。蚝油和鱼露与其他样品的气味差异显著,昆布酱油和牡蛎酱油在气味上接近,牡蛎酱油和海鲜味酱油的滋味丰富性优于其他样品,蚝油的滋味丰富性最差。智能感官分析技术适于分析海鲜调味汁这类咸鲜调味料,对产品风味品质提升有实际意义。  相似文献
