Abstract
The invention provides a method for identifying genuine and fake honey. The genuine and fake honey is identified by determining whether the enzyme activity of beta-glucosidase in honey exists. The authenticity of honey is in proportion to the detected enzyme activity; a product contains more natural honey when absorbance is higher; and the product contains fewer natural honey when the absorbance is lower. The enzyme activity of beta-glucosidase in the honey is represented by an enzyme activity unit in each gram of honey; and one enzyme activity unit is represented by enzyme amount required by catalyzing one micromole of p-nitrophenol each minute. The method is suitable for identifying the raw materials of the honey or a product prepared from honey serving as raw materials and identifying whether a fake material is mixed in the product. The method is high in flexibility, easy to operate, low in cost and suitable for popularization, and the conventional instrument is used.
Description
Technical field
The invention belongs to the food quality control method, relate to a kind of honey authenticity discrimination method, the beta-glucosidase enzyme activity has or not the true and false of judging honey in the honey by measuring.
Background technology
Honey is nectar, secretion or the honeydew of honeybee herborization, after self secretion combines, through transforming in honeycomb, dehydration, storing the crude sweet material (GB18796-2005) that forms to ripe process.Honey contains abundant essential amino acid, vitamin, Polyphenols, flavonoid class, polysaccharide, organized enzyme and carotenoid isoreactivity material, has different physiological roles, as anti-oxidant, antibiotic, acceleration of wound reparation and enhance immunity etc.Honey is a kind of natural prodcuts, has higher medical value and health care value, and the market demand is bigger, and price is higher relatively, and therefore, honey adulteration phenomenon is of long duration.
In recent years, honey is mingled and developed into materials such as mixing glucose, glucose syrup, HFCS, and is very similar to natural honey on the organoleptic indicator of these false honey products and the part physical and chemical index.Can solve the syrup that high-fructose corn syrup etc. derives from the C4 plant with stable carbon isotope method and mingle problem (Hu Fuliang, 2000).But paddy rice and nectariferous plant belong to C3 plant together, so the problem of mingling of rice HFCS can't be differentiated with the method.Honey mingle and the sound development, the export trade that have influence on the honey industry of faking earned foreign exchange and consumer's rights and interests protection, need to strengthen the research of honey authenticity authentication technique.
Honey is animals and plants double source product, so, can in natural honey, seek a kind of endocrine some particular matter of honeybee body that derives from order to differentiate true and false honey? honeybee has added multiple enzyme when brew honey, can we judge the true and false of honey by detecting these enzymes? Low etc. (1986) find to exist beta-glucosidase first in honey, in 11 kinds of honey samples of its mensuration, all can record this enzyme.Pontoh etc. (2002) are the separation and purification beta-glucosidase from hypopharyngeal gland, stomach and the honey sac of apis mellifera, and the result shows that the beta-glucosidase that extracts in three tissues is the same.Therefore they infer that beta-glucosidase is to be produced by hypopharyngeal gland, are secreted in the mouth, by the arrival honey sac of feeding, transfer to honeycomb from honey sac then.We all can detect the beta-glucosidase enzyme activity in the honey, and do not detect this enzyme activity in nectar several years ago also finding in the honey quality Control Study, illustrate that this enzyme source is in honeybee (easy Song Qiang etc., 2010).And this enzyme is more stable in honey storage process, can be used as the index that honey authenticity is differentiated.
Summary of the invention
The purpose of this invention is to provide a kind of honey authenticity discrimination method, be applicable to and differentiate the honey raw material or be the goods of raw material only, differentiate its whether adulteration with honey.
The present invention realizes by following steps:
(1) preparation of the crude enzyme liquid of beta-glucosidase in the honey: take by weighing 1.00g honey sample, be settled to the 10ml volumetric flask with citric acid-sodium hydrogen phosphate damping fluid;
(2) measure beta-glucosidase enzyme activity in the honey: draw 1.0 ml crude enzyme liquids and 1.0 ml, 30 mM right-nitrobenzophenone-β-D-glucoside is in test tube, mixing is placed on heating 1.5 h in 37 ℃ of water-baths, adds 5.0 mL, 1 M Na immediately in the reaction mixture in water-bath after the heating
2CO
3The stop buffer cessation reaction is cooled to after the room temperature and measures absorbance at 400nm wavelength place;
(3) differentiate honey according to measured beta-glucosidase enzyme activity: the authenticity of honey is directly proportional with measured enzyme activity, and absorbance is high more, and it is many more to contain natural honey; Absorbance is low more, and it is few more to contain natural honey.
The beta-glucosidase enzyme activity is the enzyme activity unit (unit/g) that has in every gram honey in the honey; Enzyme activity unit is an enzyme activity unit for per minute catalysis forms the needed enzyme amount of micromole's p-nitrophenol.
Concrete criterion: when detected beta-glucosidase enzyme activity is higher than 0.5 U/g in the honey, can assert that this honey is pure natural honey; When detected beta-glucosidase enzyme activity is lower than 0.4 U/g in the honey, can assert that this honey is the honey of mingling; When detected beta-glucosidase enzyme activity is lower than 0.2 U/g in the honey, can assert that this honey is the honey of mingling more than 50%; When detecting in the honey, then think not contain the fraud thing of natural honey less than the beta-glucosidase enzyme activity.
Another object of the present invention provides described method at the honey raw material or only be to have or not in the goods of raw material in the judgement of natural honey to use with honey.
Method provided by the invention has the following advantages:
In the honey beta-glucosidase enzyme activity at the equal stable existence of different conditions of storage.Can differentiate not only whether fresh honey is mingled, also be applicable to only be the goods of raw material with honey.
2. beta-glucosidase derives from honeybee in the honey, and therefore, this method is not only applicable to whether mix grapes fruit syrup class material in the honey, is applicable to yet and mixes other material in the honey.
3. the inventive method is highly sensitive, uses conventional instrument, and simple to operate, cost is low, is suitable for applying.
