海参是我国传统的滋补海洋食品与重要的经济水产品。海参极易自溶的食品原料学特性决定了绝大部分海参原料需要经过加工才能进入市场流通与消费,使得加工成为海参产业链的关键环节。明确海参在加工过程中的组分与食品结构变化,是阐释海参产品品质形成机理的核心,对设计开发海参高品质加工新技术具有重要的理论指导意义,是关乎海参产业发展的关键科学问题。本文概述了海参的组分及食品结构特征,归纳了海参的关键加工环节,以此为背景着重梳理了海参在水煮、干燥、复水、酶解、即食海参加工等过程中组分及食品结构变化的相关研究进展,提出了深入研究的建议,以期加速上述科学问题的解答、推动海参产业的高质量发展。 相似文献

不同加工方法对新鲜的、干制的以及制罐产品的两种海参品种的营养含量、组织结构以及海参毒素含量的进行了分析与测定,新鲜的海参含水量89—91％,蛋白质5—6％,脂肪0.3％,灰分3％以及醣0.3％;干制海参含水量26％,蛋白质61—70％,脂肪2—3％,灰分16—24％以及醣2—3％。新鲜的海参在组织中含有90毫克海参毒素/100克;罐制海参含有水份和蛋白质含量与一般鱼类、鲸鱼等相似.用罐制加工海参的方法,其结果明显差异(P<0.01),以使罐制海参的钾含量降低,而钠含量反而增加,用制罐海参制品、新鲜煮熟海参、煮熟后盐罐海参以及煮熟后于制海参三种制罐海参原料在组织结构中无明显差异(P<0.01) 相似文献

海参软罐头加工工艺的研究 总被引：3，自引：0，他引：3
由于市场上销售的海参都是干制品，烹调工序繁多，食用极不方便。如将其加工成软罐头则食用方便，且便于携带，必将有助于海参产业的发展。对此我们进行了相应的研究。 相似文献

淡干海参发展前景广阔,是海参干制品今后发展的主要趋势之一,但不同的复水条件对淡干海参的营养和口感会产生较为明显的影响,基于此本实验拟研究不同的热烫温度、热烫时间、保温温度及保温时间处理后对淡千海参的营养及口感等品质的影响。实验通过测定淡干海参在复水过程中的复水比、淡干海参质构特性（硬度、弹性）等指标,并对其进行比较分析。结果表明：经过90℃热烫20min后,在70℃保温40h,复水比达5～6的条件下淡干海参复水效果最好,质构良好、口感俱佳。此结论为淡干海参的科学食用和推广提供一定的理论基础和科学依据。 相似文献

The close relationship between the consumption of sea cucumber and health status stems from the nutritional and functional substances found in sea cucumber that play a key role in the prevention of different diseases. The processing methods have a great effect upon the nutritional and functional substances in sea cucumber. A superior product should not only be abundant in nutritional substances, but also require an easy and cost effective processing method. This study compared the influence of processing methods on the stability of macronutrients and micronutrients present in sea cucumber in order to recommend products that could provide high nutritional quality. The five processes investigated were hot air drying (60°C), vacuum freeze-drying (0.5 cm thickness material, 5–10 Pa vacuum degree, ?85 to ?90°C cold trap temperature, ?25°C material temperature), sun drying, double-distilled water cooking followed by sun drying, and 3.5% sodium chloride solution cooking followed by sun drying. A significant decrease of all the chemical compositions determined was shown in all the sea cucumber products treated by the five processing methods (p < 0.05). Among all the processing methods, hot air drying resulted in the highest nutritional quality of the product. Moreover, hot air drying can be operated easily with low cost. 相似文献

以海参水煮液的冻干粉为原料,选取中性蛋白酶、胃蛋白酶和胰蛋白酶分别酶解制备多肽,测定其对·OH、O2-·和DPPH·自由基的清除能力,并与合成抗氧化剂TBHQ对比.结果表明,3种蛋白酶酶解制得的海参水煮液多肽对·OH、O2-·和DPPH·自由基的清除能力均随样品质量浓度的升高而增强;其中,中性蛋白酶酶解制得的海参水煮液多肽清除·OH、O2-·和DPPH·自由基的IC50值依次为8.565、6.658和2.015mg/ml,其对O2·的清除能力优于TBHQ.经液相色谱法测定,中性蛋白酶、胃蛋白酶和胰蛋白酶酶解制得的海参水煮液多肽分子量分别分布在＜2 500、＜3 500和＜1 000 D的小分子肽中. 相似文献

Two feeding experiments were conducted to investigate the effects of dietary inclusion of different plant ingredients on growth and body composition of juvenile sea cucumber. In the first experiment, three replicate groups of the sea cucumber (average weight of 1.5 ± 0.05 g) were fed one of the seven experimental diets containing Sargassum thunbergii (CON), Undaria (UND), Laminaria (LAM), Brassica oleracea L. var. capitata (BRA), fermented soybean (FSB), distillers dried grain (DDG) and rice straw powder (RIC) for 10 weeks. After the feeding trial, survival was not significantly different among the dietary treatments. Specific growth rate (SGR) of sea cucumber fed the FSB diet (0.73) was significantly higher than that of sea cucumber fed the other diets (P < 0.05), except for the DDG diet (0.64). The lowest SGR was observed in sea cucumber fed the CON diet (0.14). Based on the result of the first experiment, the second experiment was conducted to determine the proper level of dietary DDG for growth of juvenile sea cucumber. Three replicate groups of sea cucumber (average weight of 1.6 ± 0.02 g) were fed one of the five experimental diets containing different levels (g kg?1) of DDG (DDG0, DDG10, DDG20, DDG30 and DDG40) for 12 weeks. Survival was not significantly different among the treatments (P > 0.05). The best SGR was obtained in sea cucumber fed the DDG10 diet (10.1) and the value of sea cucumber fed the DDG40 diet (5.6) was the lowest (P < 0.05). The SGR of sea cucumber fed the DDG10 diet did not differ from that of sea cucumber fed the DDG20 diet (P > 0.05). Moisture, crude protein, crude lipid and ash contents of whole body in sea cucumber among the dietary treatments (P > 0.05) did not differ significantly at both experiments. Results of two feeding trial suggest that dietary inclusion with 100 g kg?1 FSB or 100–200 g kg?1 DDG may improve growth of juvenile sea cucumber, and especially DDG could be used as a good ingredient for the low‐cost feed formulation. 相似文献
