目的:改善油炸鲢鱼鱼丸的食用品质。方法:添加蛋清粉与鲢鱼鱼糜进行复配,通过测定孔隙率、硬度和吸水性等指标表征鱼糜的油炸特性,测定鱼糜的动态流变学性质、泡沫稳定性,并采用SDS-PAGE探究其影响机制。结果:随着蛋清粉添加量的升高,油炸鱼丸孔隙率和吸水率先升高后降低,硬度先降低后升高,其中添加10.0%蛋清粉的效果最佳。此外,鱼糜中还出现了分子量100 kDa以上的新条带,且油炸鱼丸的孔隙率与鱼糜的凝胶性、泡沫稳定性呈正比。结论:蛋清粉的添加提高了鱼糜的凝胶性和泡沫稳定性,改善了其食用品质。 相似文献

Low‐field 1H nuclear magnetic resonance (NMR) tranverse relaxations were measured on intact and minced muscle from raw and smoked salmon differing in size (small or large) and storage days after smoking (1, 11 and 20 days). Water distribution in the samples was calculated from the NMR signals by the use of multi‐way data analysis. For intact and minced salmon samples, three water ‘pools’ with T2 values of 38, 50 and 182 ms and of 33, 50 and 183 ms, respectively, were identified. For both intact and minced samples, the size of water pool I and II were affected by storage time after smoking, whereas the size of pool III was affected by the size of the fish. Intact fillet samples taken near the skin and near the middle of the fillet differed with respect to shape of the NMR relaxation signal reflecting a non‐uniform distribution of the size of the three water pools in intact fillet.

Lactic acid bacteria‐induced fermentation of fish was tested with the purpose of developing a novel fish food product with desired meat properties. Three selected lactic acid bacteria strains, isolated from lightly preserved fish products, were inoculated into minced frozen fillet of yellowfin tuna, and changes in fish properties were observed during 52 days of storage at 8 °C. Organoleptic, bacteriological and biochemical studies (pH, histamine, TVB‐N, malonaldehyde) and shelf‐life measurements suggest that Leuconostoc mesenteroides could be considered as a possible starter culture for fish fermentation, but additional experiments should be performed. © 2000 Society of Chemical Industry 相似文献

以魔芋葡甘聚糖(KGM)和乙基纤维素(EC)为基材,添加五倍子提取物制备可食性抗菌膜。测定了复合膜的拉伸强度、断裂伸长率、水蒸汽透过率及阻氧性,并将其应用于生鲜鱼片保鲜包装,测定了储藏期内鱼肉的p H、挥发性盐基氮(TVB-N)值和菌落总数。结果表明,KGM/EC复合膜拉伸强度随五倍子水提物添加量的增大而显著降低,当五倍子水提物添加量大于15%时,其拉伸强度无显著变化(p<0.05)。随着五倍子水提物添加量从0%增加至20%时,复合膜断裂伸长率显著性增加且水蒸汽透过率显著性降低(p<0.05),另外,膜的阻氧性显著性提高(p<0.05)。采用添加20%五倍子提取物的复合膜(w/w)用于鱼片冷藏包装,鱼片保鲜的主要参考指标(p H、TVB-N值和菌落总数)与未用膜包装组和未添加五倍子复合膜组相比,均有显著性差异(p<0.05)。以菌落总数为参考指标,添加20%五倍子含量的复合膜包装的鱼片与未用膜包装鱼片相比,其4℃储藏条件下货架期延长了3 d。魔芋葡甘聚糖-乙基纤维素复合抗菌膜在食品保鲜上具有一定的应用前景。 相似文献

Pollock were removed from ice or refrigerated seawater after 2, 4 and 6 days and processed into fillet blocks or fillet blocks containing 15% or 30% minced flesh. Although all the samples were acceptable after 12 months, the addition of minced flesh and storage at - 18°C affected texture and flavor. This was particularly evident for blocks containing 30% minced flesh, and results suggest the addition of minced flesh should be limited to 15%. Changes in dimethylamine and expressed thaw drip may explain the changes in sensory attributes since there were small changes in the control blocks held at ?34°C. 相似文献

The objective of this study was to examine the effect of washing pre-treatment on mercury concentration in fish fillet. Response surface methodology was used to investigate the influence of three variables, pH (1–6.5), NaCl (0–1% w/v) and exposure time (5–30 min) by using a three-factor central composite design. The aim was to obtain the best possible combination of these variables in order to reduce mercury in fish fillet. The experimental data were adequately fitted into a second-order polynomial model with multiple regression coefficients (R 2) of 0.961. The results indicated that the reduction of mercury in fish flesh significantly depends on the pH of the solution used. The overall optimal condition resulting in the maximum mercury reduction in fish fillet was obtained at a combined level pH of 2.79, NaCl of 0.5% and exposure time of 13.5 min. The optimized protocol produced a solution that can reduce mercury from raw fish fillet up to 81%. 相似文献

Minced fish flesh, as well as the intact fillet, from three species of the Gadidae family were analyzed for proximate composition, cholesterol, and calcium content. Minced fish meat produced from commercially scaled whiting had elevated levels of calcium (about 0.11%) over levels found in filleted flesh (0.03%). Hand scaling prior to mincing brought the calcium content close to levels found in skinless fillets. The minced flesh for all species had the following ranges of values for proximate composition expressed as percent of wet weight: protein, 14–17%; fat, 0.4–2.0%; moisture, 81–84%; ash, 0.5–1.9%. 相似文献
