Abstract
The utility model discloses a chlamys colorimetric fan which comprises a fan body and a fan handle, wherein the fan body comprises a color region and a numerical value region, the color region comprises ten color standard gradients which are mutually separated from left to right, the numerical value region comprises ten numerical values respectively corresponding to the ten color standard gradients in the color region, and the fan body is connected with the fan handle. The chlamys colorimetric fan is used for being compared with a chlamys adductor muscle color, and thus the range of the content of the total carotenoids in the chlamys adductor muscle can be obtained within 3-5s. The range of the content of the total carotenoids in the chlamys nobilis adductor muscle is determined by using the chlamys colorimetric fan and is 10-250 micrograms/g. The chlamys colorimetric fan is used for determining the range of the content of the total carotenoids in the chlamys nobilis adductor muscle, and has the advantages of rapidness, convenience in use, practical applicability and the like.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of scallop colorimetric of Fast Measurement Chlamys nobilis closed shell intramuscular total carotinoid content fan.
Background technology
Carotenoid (carotenoids) also claim chromolipid, belong to terpenoid compound, the general name of the hydrocarbon of 40 carbon (carrotene) and their oxidized derivatives (xenthophylls) two large class pigments normally, synthetic by higher plant, algae and microorganism, be present in nature with yellow, orange red or red isochrome prime form, be found up to now to reach 750 kinds.
Because carotenoid is widely distributed, and have various function and special nature, first from isolating yellow beta carotene carrot, carotenoid research was just one of people field of being most interested in always from people in 1831.The carotenoid color and luster is vivid, the look valency is high, has been widely used in colorant, feed addictive; Carotenoid has biologically active, particularly oxidation resistance is strong, except as functional food, it also has health care and medical value, strengthens immunity of organism, treats photosensitive diseases and prevent that cataract from occuring etc. as the precursor of vitamin A as the vigor of removing B cell in free radical resisting oxidation and delaying senility, quenching singlet oxygen cancer-resisting, increase immune system.Therefore, the application of carotenoid also progressively turns to nutraceutical, health products and medicine three large field from initial colouring function.
Mollusc itself can not be synthesized carotenoid, but they are rich in the algae of carotenoid and accumulate a large amount of carotenoid in different tissues in vivo by ingesting, and ingested by fish, seabird, marine mammal and the mankind as important food source and enter (Kantha, 1989) in the vertebrate body.Therefore, in food chain, mollusc is that carotenoid enters the interior very important rings of high vertebrate body such as people.
Chlamys nobilis (Chlamys nobilis Reeve) is water warm marine products bivalve (Qi Zhongyan, 1998; Cai Yingya etc., 2006), and famous, its closed shell flesh dried product is commonly called as " dried scallop " with nutritious, delicious flavour, fine and tender taste, is one of famous marine products eight delicacies.Since the last century late nineteen seventies, begin to propagate artificially Chlamys nobilis at south China, the eighties middle and later periods is just developed into one of coastal important sea-farming kind in south.
That Chlamys nobilis not only has on shell is golden yellow, brown, purple brown, the shallow multiple exterior color such as brown of orange, and on the color of the interior tissues such as outer embrane, closed shell flesh, difference is arranged also, is all white as outer embrane, the closed shell flesh of brown individuality; Closed shell flesh golden yellow, 20 ~ 30% individualities also is golden yellow and the outer embrane of golden yellow individuality is generally, and the tissues such as this flavous closed shell flesh, outer embrane are rich in carotenoid, and is subject to heredity control.By artificially breeding, not only cultivated outside color and luster attractive in appearance and be rich in the golden new lines of natural carotenoid, and carried out large-scale cultivation in marine sites such as Fujian, Guangdong.The custom that meets China consumers in general due to the appearance luster of this golden strain, the carotenoid of its high-load has again the value such as higher economy, medical treatment and health care, and therefore, the value of product is far above common variety.So not only solve the problems such as the product price that present Chlamys nobilis aquaculture meets with is low-priced, the output value is low, and can further enrich many kinds demand of China's mariculture industry.Because one of the principal character of this new lines and economic characters are exactly to be rich in carotenoid in its body, therefore, in the processes such as production, market sale, measure quickly and easily that in their bodies, total carotinoid content will become an important link.
Conventional mensuration shellfish total carotinoid content adopts following method always: 1) adopt vivisection to get its interior tissue sample; 2) vacuum freeze drying and grinding: 3) press Zheng etc. (2010, Zheng HP, Liu HL, Zhang T, Wang SQ, Sun ZW, Liu WH, Li YY.Total carotenoid differences in scallop tissues of Chlamys nobilis (Bivalve:Pectinidae) with regard to gender and shell color.Food Chemistry, 122,1164-1167.) method in the dark spends the night with acetone, extracts the total carotinoid in sample; 4) the centrifugal 5min of 5000rpm gets supernatant, carries out spectral scan with spectrophotometer; 5) at last with reference to Zheng etc. (2010, Zheng HP, Liu HL, Zhang T, Wang SQ, Sun ZW, Liu WH, Li YY.Total carotenoid differences in scallop tissues of Chlamys nobilis (Bivalve:Pectinidae) with regard to gender and shell color.Food Chemistry, 122,1164 – 1167.) the total carotinoid content in the method calculation sample.This method has many shortcomings: 1) complicated, the length consuming time of flow process, from sampling, drying, grinding, extraction, centrifugal, analyze mensuration and complete general need 1 time-of-week; 2) instrument and equipment is many and expensive, comprises the equipment such as expensive vacuum freeze drier, ultraviolet spectrophotometer, supercentrifuge and muller, pipettor; 3) need to carry out the chemical extraction total carotinoid with organic solvent, not only cost is high, and easy contaminated environment; 4) poor practicability: can not carry out on-site measurement, must carry out in the laboratory; Method is loaded down with trivial details, need the professional to operate, and can't be applied in practice.
Because Chlamys nobilis is the important cultivated shellfish in south China sea area, scale is large, output is high.This new varieties that are rich in carotenoid need the carotenoid content of frequent on-the-spot living body measurement product in cultivation is promoted.Adopt conventional method far can not satisfy the requirement that practical generation detects.Therefore, must there be a kind of fast and convenient and practical method to measure total carotinoid content.Yet, up to now, there is not yet any report about fast and convenient mensuration shellfish total carotinoid content.
