番茄海带富碘复合汁的研制

以海带和番茄为原料通过科学调配，研制而成天然碘复合饮料。其工艺特点是将海带通过一系列加工程序，在保持其天然营养的前提下加工成汁，然后与番茄汁、菠萝汁及其它辅料按其营养成分进行科学合理的调配，从而制成每瓶含碘８０～９０μｇ的天然补碘饮料，该饮料具有营养补碘之功效，又具有色、香、味俱佳的特点。     

海带浸泡液中碘的电化学提取

海带浸泡液中碘的提取一直沿用化学氧化法,该法存在着过氧化及环境污染问题,国内曾在70年代改用电化学氧化法,但当时只限于对实验条件的选择,而在电极材料的研究及应用方面却未见报道。为此,我们试制了一种具有电催化活性的阳极,并对海带浸泡液中I—的电化学氧化进行初步研究。

Reproductive biology of Limnoria chilensis: another boring peracarid species with extended parental care

Several boring peracarid species engage in extended parental care with parents tolerating small juveniles in their burrows, but only anecdotal observations have been reported from boring isopods of the genus Limnoria. The isopod Limnoria chilensis Menzies is frequently found in holdfasts of the macroalgae Macrocystis pyrifera (L.) C. Agardh and Durvillea antarctica (Chamisso) Hariot. In the present study, holdfasts of D. antarctica that harboured L. chilensis were carefully dissected in order to examine the association pattern of reproductive females and small juveniles. In most infested holdfasts, L. chilensis reached very high densities of 43.7 ± 3.9 (mean ± SE) individuals cm^?2 (range: 0–90 individuals cm^?2). The overall sex ratio (females:males) was close to unity (1.2). Male size varied between 1.5 and 2.6 mm body length (BL) and female size between 1.5 and 3.6mm BL. The percentage of reproductive females was low (19.7% of all females), and only the largest females (>2.6 mm BL) were reproductive. Embryo numbers ranged between six and 19 per female and a significant correlation between female BL and the number of embryos was found. Several females were found with small juveniles (0.8–1.2 mm BL) in the terminal end of their burrows. On several occasions, aggregations of similar-sized juveniles (1.0–1.5 mm BL) in their own burrows were found near a female burrow, indicating that these juveniles initiated their first individual burrows from within the maternal burrows. Some females with small juveniles in the terminal end of their burrows were either accompanied by males or they were ovigerous, indicating that they may have been in the process of producing a second brood. The fact that juveniles build their first burrows in the protection of female burrows suggests that such small juveniles have not yet developed full boring capacity. Extended parental care in this (and other boring) peracarid species represents a mechanism facilitating high juvenile survival rates. Given the highly local recruitment, it is suggested that the reproductive biology of this isopod has strong implications for Its population biology.

药食同源植物海带中多不饱和脂肪酸的组成特点

采用索氏提取法以不同溶剂提取干海带中的总脂肪酸,提取物经碱液水解和三氟化硼甲酯化后,采用气相色谱-质谱联用技术分析海带提取物中多不饱和脂肪酸的组成特征。实验结果表明,乙醇、丙酮和石油醚的总提取率分别为11.92%、3.93%和3.22%。在GC/MS检测结果中,石油醚提取物、丙酮提取物、乙醇提取物中不饱和脂肪酸分别为2.82%、60.40%和60.41%。石油醚溶剂不适合提取海带中的不饱和脂肪酸,丙酮和乙醇溶剂较好,丙酮提取物中多不饱和脂肪酸的含量为28.68%,乙醇提取物中则为30.29%。以乙醇为夹带剂对海带中脂肪酸进行超临界二氧化碳流体萃取,GC/MS检测结果表明不饱和脂肪酸的比例为79.04%,多不饱和脂肪酸的比例为52.13%。超临界二氧化碳萃取法更适合海带多不饱和脂肪酸提取,能提高海带产品的附加值。
