Standards Propolis Quality
Propolis from several locations in portugal, including islands, was fully characterized in terms of physicochemical properties, phenolic composition and antioxidant activity, enabling the establishment of quality standards. color, frequently used as a commercial parameter, standards propolis quality was accessed by the first time in propolis with the cielab system, and. Propolis is a mixture of substances used by bees to defend the hive. this protection concerns filling cavities in the walls of the hive, reducing the entrance during cold days, and also mummifying the demanded intruders, thus preventing their decay []. this explains why propolis is also known as bee glue []. the word, propolis, is greek in origin and means at the entrance to the city [3,4].

The necessity of a quality standard for propolis is obvious. ideally, a quality standard should propose methods that are fast, low cost, accurate, reliable and reproducible. in the present there are only two standards for propolis: a russian standard unfortunately unavailable and with outdated methods, and the argentinian standard for propolis [9]. The results presented in this study, demonstrated for the first time in the literature the chemical reproducibility of three independent batches of propolis extract compared with six standards. almeida et al. (2010) studied the chemical and functional reproducibility of the extracts from castanea sativa by comparing the fingerprint of the. Comb, propolis, or other defects normally found in honey, have been removed. grains of pollen, small air bubbles, and very fine particles would not normally be removed. §52. 1394 definitions of terms. as use d in these u. s. standards, unless otherwise required by the context, the following terms shall be construed, respectively, to mean:. Aspects: propolis in the bee colony, chemical composi-tion and plant sources of propolis, biological activity of propolis with respect to bees and humans, and approaches for standardization and quality control for the purposes of industrial application. 2. resin and propolis: sampling and harvesting propolis collected from the hive may contain.
(pdf) quality criteria for propolis standardization.
Grades of extracted honey. u. s. grade a is the quality of extracted honey that meets the applicable requirements of table iv or v, and has a minimum total score of 90 points.. u. s. grade b is the quality of extracted honey that meets the applicable requirements of table iv or v, and has a minimum total score of 80 points.. u. s. grade c is the quality of extracted honey that meets the. Official quality standards exist for propolis in various east european countries, but most standards refer to the cleanliness or adulteration of the raw product and sometimes, its extracts. maximum and minimum limits for certain chemical groups are set, but few standardised tests are available to determine the biological activities of various. Propolis is standards propolis quality a resin that honeybees produce by mixing saliva and beeswax with exudates gathered from botanical sources. the amount of each of these compounds is often used as an indication of propolis quality, which depends on the phytogeographic and climatic conditions around the beehive [39, 40].
In raw propolis the minimum criteria were set as 1% of each flavanone and in purified propolis after alcohol extraction as 2%. the virtual absence of quercetin was also a criterion for acceptance. this method is now accepted by the uk food standards agency (fsa) and local authorities coordinators of regulatory services (lacors). It is suggested that other tests, e. g. orac (oxygen radical absorbance capacity) and antimicrobial tests, should be considered in setting international quality standards for propolis. assuming that propolis and products of other standards propolis quality bees have antibacterial activity, their combination should intensify this effect.

Qualitystandards for bee products in general and propolis in particular must be for the benefit of producers, distributors, and consumers as well as. the present study shows that higher content of wax was determined in propolis samples obtained by scrapping the frames with hive tools than in samples obtained through propolis collector.
