Honey is a natural sweetening substance produced by bees when they collect nectar, secretion or honeydew from plants and mix them with their own secretion. Studies have shown that honey contains a variety of free amino acids, of which proline is the highest and a unique amino acid. Pollinating insects have the ability to taste this amino acid. The content of proline in honey is also related to its antioxidant capacity. Therefore, the content of proline in honey is not only used as a standard to measure the content of free amino acids in honey, but also as a criterion to judge the maturity and sugar adulteration of honey. The content of proline in pure honey should not be lower than 180m.G/ kg.

The content of proline in pure honey should not be not180mg/kg.

Biino first proposed proline content as an indicator of honey quality. So far, only proline can be used to evaluate the quality of honey and judge whether honey is adulterated or not. Proline is also one of the few amino acids with antioxidant activity. Studies have shown that the content of proline in honey is higher than the total phenol and total flavonoids, and its content was positively related to the concentration of phenolic compounds. Therefore, the determination of proline content in honey, not only can provide a theoretical basis for the quality analysis of honey, but also has very important significance in the evaluation of the antioxidant activity of honey.

Biino suggested for the first time that proline content should contentAn index to evaluate the quality of honey. So far, only, SoEvaluate the quality of honey and judge whether honey is adulterated isProline is also one of the few amino acids with antioxidant withHave shown that the content of proline in honey is higher isPhenols and flavonoids, and the content is positively correlated with theConcentration of phenolic compounds. Therefore, the determination of prolineContent in honey can not only provide a theoretical basis for basisDetection of honey, but also play an important role in evaluating evaluatingAntioxidant activity of honey.

proline in honey comes mainly from the nectar nectar plants and the secretion of bees. Proline synthesis and accumulation and metabolism of nectar plants is regulated by a proline concentration of abiotic stress and intracellular physiological and biochemical processes, there are two proline biosynthesis in plants, namely the glutamate pathway and ornithine pathway. In bees, proline as an important part of the The new supersedes the old. produced by bees, the tricarboxylic acid cycle in the metabolism of their own, and enriched in bee hemolymph, affect the physiological metabolism of bees. The content of proline in honey is not only related to the type of honey, but also related to the geographical environment.

The proline in honey mainly comes from nectar of honey plants a Nd theSecretion of bees themselves. Proline synthesis, accumulation and metabolism inNectar plants is a physiological and biochemical process regulated by abioticStress and intracellular proline concentration. There are two proline synthesisPathways in plants, namely glutamate pathway and ornithine pathway. Proline, asAn important part of bee metabolism, is produced by the cyclic theTricarboxylic acid and enriched in the hemolymph of bees, which affects whichPhysiological metabolism of bees. The content of proline in honey is honeyRelated to the type of honey, but also related to the toEnvironment.

is ripe honey capping honey, bee biological enzyme and its the collected nectar for brewing, nectar fully converted, while the nectar of water evaporation out, and then use the secretion of beeswax to honey brewed by capping. The moisture content of mature honey is generally less than 18%. In Germany, the content of proline is less than 180.Mg/ kg honey is considered immature honey. According to the data given in Table 1, the content of proline in most honey varieties is more than 180 mg/Kg, for rape, lemon and rosemary and other botanical varieties of honey, the proline content is low, limiting the ripe honey value determined also need more research. In addition, for some immature honey, after concentration, proline content changes also need to be studied, in order to avoid the situation posing as ripe honey.

Mature honey is to seal the honey, bees use their, beesCollect nectar for brewing, the nectar will be fully converted, whileEvaporating the water out of the nectar, and then secreted beeswax secretedBrewed honey and get. The moisture content of mature honey is honeyThan 18%. In Germany, honey with a proline content of less less 180Considered immature honey. From the data given in Table 1, it can itThe proline content of most honey varieties is more than 180 mg/kg, thanRape, lemon and rosemary and other plant-derived honey varieties, the prolineContent is low, and more investigation is needed to determine the determineMature honey. In addition, for some immature honey, after concentration, theChange of proline content also needs to be studied, in order inTo mature honey.

be results showed that the proline content was significantly higher than that of rape honey from datehoney, there are significant differences in different regions with proline content of honey, the proline content was significantly higher than that of the south north area of honey. Jujube honey and rape honey proline content varied greatly, many factors which may growth and nectar plants of different geographical environment, honey in the brewing process of the change of the. The free amino acid is a good indicator of nectar and honeydew honey from honey, are used to identify plant sources of amino acids. Proline is the main amino acids in honey, this parameter is considered different characteristics of single flower honey value. However, in a single flower in different kinds of honey, proline content changes, plant source is still difficult to only a single index to identify the single proline content of honey.

The results showed that the content of proline in jujube inSignificantly higher than that in rape honey, and there were significantDifferences in the content of proline in the same honey in honeyThe content of proline in honey in northern region was significantly wasThat in southern region. The content of proline in jujube nectar jujubeVaried greatly, which might be related to the different geographical environmentOf nectar plants and the changes in honey brewing process. Free process.Good indicators of the source of nectar and honey dew, and dewUsed to identify the source of honey plants. Proline is the isHoney. This parameter is considered to be the characteristic value of valueSingle flower honey. However, the content of proline varies greatly in greatlySingle-flower honey, and it is difficult to identify the plant source plantHoney only by the single index of proline content.
