崭露头角的鱼胶原蛋白 总被引:2,自引:1,他引:1
1鱼胶原蛋白产业
胶原蛋白是哺乳动物体内含量最多的蛋白质,约占人体内蛋白质总量的25%~30%.相当于体重的6%。胶原蛋白几乎存在于体内所有器官和组织。人在25岁以后合成胶原蛋白的能力逐渐下降,每年以1%~3%的速度流失。随着老年化社会的到来,皮肤皱纹、骨质疏松和关节疼痛日益呈现,补充胶原蛋白成为必然的社会需求。 相似文献

The wound dressing material has been fabricated with the novel Arothron stellatus fish skin collagen scaffold loaded with a bioactive extract obtained from Coccinia grandis (CPE) and drug Ciprofloxacin (D). The collagen scaffold was fabricated from the nonedible solid waste of marine origin (a cheaper source of raw material). The in vitro fluorescence staining of cells and in vivo evaluation of the fabricated scaffold exhibited enhanced cell adhesion and proliferation and indicated a more efficient wound healing paradigm than that of the control and other treated groups, respectively. The increased collagen synthesis and re-epithelialization of wound are proved to be potential wound constructs. 相似文献

Waste oils are potentially advantageous over petroleum and virgin vegetable oil based fuels due to waste utilization, and an overall lowering of gases and most other emissions over the life cycle of fuel production, use, and disposal. Waste generated from fish processing plants varies from 10–50 wt% of landed fish depending on the type of fish, product and processing techniques. A portion of this waste contains fish oil and varies significantly depending on the species. The oil recovery process must maximize extraction of oil and at the same time be able to integrate into the existing infrastructure at fish plants. In this study, we have optimized the recovery process developed in our lab (based on a fishmeal processing) and tested with the waste of a variety of fish species. The oil had low impurities (<0.5 wt% moisture) and degradation products, and physical properties suitable for substitution of No. 6 fuel oils and marine distillate/residual fuels. Based on this, pilot scale experiments were performed to determine scale-up challenges and design specifications for eventual costs analysis (e.g. size, residence time, etc.), energy required and waste emissions. 相似文献

Fish collagen, a kind of fibrous protein, and egg white protein were selected as foaming agent to prepare ceramic foams by protein foaming method. Ceramic foams with open porosity of 84.8–86.9%, average pore size of 216–266 μm and compressive strength of 8.7–13.7 MPa were fabricated. Studies of fish collagen addition on the influence of open porosity, pore size distribution and mechanical property of ceramic foams were investigated. In comparison with single addition of 8 wt% egg white protein, the combinational addition of 2 wt% fish collagen and 6 wt% egg white protein results in 23% increase in average pore size. In addition, the introduction of fish collagen decreases the count of small pores. Moreover, with the introduction of fish collagen, pores become regular in shape. 相似文献

Comparison of the effects of collagen and modified collagen fillers on the properties of XNBR rubber
The aim of this study was to compare the effects of 5 to 30 parts by weight of unmodified and modified collagen on the properties of XNBR rubber vulcanized with a cross‐linking system. This study is a part of experimental series concerning polymeric materials that are biodegradable due to their filling with a waste protein such as collagen. © 2009 Wiley Periodicals, Inc.

Fish scales are an abundant biowaste apparently unused, except for isolating major components as feedstocks, sacrificing the useful properties inherent to scales. We modified scale surfaces using hydrophilic and hydrophobic (meth)acrylates and tetraethylorthosilicate with in situ polymerization, and partial degradation of the biomineral or collagen layer. Chemical changes were assessed qualitatively by Fourier‐transform infrared spectroscopy and quantitatively by nanomechanical analysis. No modification was selective but they were “preferential”. Hydrophobic modifications were inefficient and reduced scale modulus. Inorganic and hydrophilic modifications were efficient and increased modulus. On adding sodium‐citrate‐modified scales to a weak alginate hydrogel, rheology showed an order of magnitude increase in storage modulus compared to alginate with no or unmodified scale reinforcement. Fish scales can be a useful new reinforcement. This work highlights simple pathways to manipulate surface composition and modulus of waste fish scale to enhance composite properties. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Superfine fiber synthetic leather is a high-grade artificial leather product with numerous characteristics and advantages. However, compared with natural leather, it shows poor moisture absorption and moisture permeability, and it gives people a hot and tacky feeling; thus, the improvement of these properties has become a popular topic in the industry. In this paper, the “click” chemistry method was employed to modify the nylon fiber of the superfine fiber synthetic leather base with waste collagen to improve the moisture absorption and permeability of the superfine fiber synthetic leather base, thus enhancing the hygienic performance and wearing comfort of the end products, realizing waste recycling. This study obtained the optimal reaction conditions for the “click” modification of unfigured sea-island superfine fiber synthetic leather base with collagen methacrylamide. The characterizations by static contact angle measurements, attenuated total reflection infrared spectroscopy, and X-ray photoelectron spectroscopy analysis confirmed that collagen was successfully grafted onto the surface of the nylon fiber. Compared with the original base, the moisture absorption, and permeability of the base were improved by 602.4% and 43%, respectively. This study shows the theoretical research significance and excellent practical value for the resource utilization of skin collagen waste. 相似文献

Materials previously shown to elicit increased tongue-flicking and prey attack in garter snakes (Thamnophis sirtalis) were isolated from both earthworms (Lumbricus terrestris) and fish (Pimephales promelas). Both high- and low-molecular-weight components from earthworms and fish stimulated attacks and increased tongue-flicking in previously unfed neonate garter snakes relative to distilled water controls. Earthworm collagen was also effective, but even concentrated fractions were less effective than raw extract. Conflicting reports on the effectiveness of collagen suggest that the salient chemical(s) is a smaller molecule tightly bound to collagen and resisting standard purification methods. 相似文献

In fish and poultry processing, viscera are generally considered as a waste product and often discarded. Chicken and hilsa
fish (Hilsa ilisa) viscera were used for the production of polyunsaturated fatty acids (PUFA) linoleic (18:2n-6), eicosapentaenoic (EPA; 20:5n-3)
and docosahexaenoic acid (DHA; 22:6n-3). Free fatty acids (FFA) were extracted by alkaline hydrolysis of chicken and fish
viscera; yields were 5.2 and 5.9% (w/w) respectively. PUFA concentrates were obtained by a two step process—deduction of saturated
fatty acids (FA) by low temperature crystallization in acetone followed by urea inclusion compound-based fractionation. Acetone
treatment removed 90 and 96% of saturated FA in chicken and fish viscera respectively with FA to acetone ratio of 1:12 (w/v).
Using an urea to FA ratio (w/w) of 4.0, chicken viscera produced a maximum of 84.1% of PUFA concentrates containing 82.1%
of linoleic acid with a yield of 10% where as in the case of fish viscera the maximum PUFA concentrates were 91.3% containing
78.2% of EPA-DHA with the yield of 11%. Thus, the utilization of poultry and fish processing waste into the production of
PUFA concentrates has been shown. 相似文献
