Quality standards Beeswax Beeswax is an important basis for measuring the merits, but also on norms beeswax production. People's Republic of China has formulated and promulgated China Business industry standard - "beeswax" and the Chinese Ministry of Foreign Trade on the output beeswax "standard" (Table 10, Table 11). Table 10 People's Republic of China Ministry of Commerce Industry Standard SB/T10190 -93 "beeswax" ┌ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┬ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┬ ─ ─ ─ ─ ─ ─ ┐ │ │ │ a grade two product │ ├ ─ ─ ─ ┬ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ┤ │ │ colors melted │ white, yellow, bright yellow, yellow, orange │ │ │ │ type odor after │ have beeswax flavor, no smell senses to │ │ │ │ │ matte surface, wavy, generally seeking middle bulge │ │ │ │ section │ broke down the section, no denim, compact structure, │ │ │ │ │ down uniform color, fine particles of uniform │ │ ├ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ┼ ─ ─ ─ ─ ─ ─ ┤ │ │ physical and chemical impurities (benzene does not │ 0.3 │ 1.0 │ │ │ indicators solubles), Rui │ 0 .954-0.964 │% beeswax 70 in a 79 │ │ │ density (ZWC) │ West beeswax 62.0 a 67.0 │ 69 │ │ │ 60 a melting point (℃) │ 1.4410 ~ 1.4430 │ │ │ │ │ refractive index in beeswax 5.0 a 8.0 │ │ │ │ (759C) │ West beeswax 16.0 a 23.0 │ │ │ │ acid value │ 8.0 ~ 13.0 │ │ │ │ (KOH n na g) │ 75.0 ~ 110.0 │ │ │ │ iodine value (in beeswax 80 an iodine │ 95 │ │ │ │ years old 100g) │ West beeswax 70 a 80 │ │ │ │ saponification value │ │ │ │ │ (KOH mg / g) │ │ │ │ │ Cool value │ │ │ │ │ (KOH mg / g) │ │ │ │ │ │ │ │ hydrocarbons do not allow people to add other natural beeswax material from the People's Republic of China Ministry of Commerce Industry Standard SB/T10190 -93 "Beeswax."

After the above time through identification, it can not be concluded, then the instruments - were identified by gas chromatography. 1 Wang Yi beeswax sensory identification section editor of the "Bee Products Science," a book that, for beeswax sensory identification, usually seeing, ears, nose and smell, biting, pushing finger nails from and pinch, pull and twist with fire and other methods. ① seeing: pure beeswax bright colors and dull surface often raised, wavy, section compact structure, fine crystal grains, dull. Mixed with paraffin wax shiny, shiny, smooth surface or depression, no ripples, cross-sectional structure of loose, coarse crystal grains, showing shiny white granular, needle-like or twill. ② ears: a hammer with a stick beeswax or beeswax to fall from a high place on the hard ground, pure beeswax sounds boring dumb, adulteration of beeswax crisp sound. ③ nose smell: the beeswax block knocked, immediately smell the section. Pure beeswax exudes scent of beeswax, beeswax adulteration or tasteless odor. ④ biting: Take a small piece of beeswax, teeth repeatedly crunch. Pure beeswax is not broken, leave and stick teeth, biting into a slice without holes; adulterated beeswax fragile, fugitive, sticky teeth, biting into flakes easily perforated. ⑤ refers push: thumb belly on the surface of the wax block to move forward. Pure beeswax surface astringent; adulteration of beeswax smooth surface, or send Bo, cloying, weak. ⑥ nails from: forward from the surface of the wax block with nails, not from pure beeswax wax flowers; beeswax mixed with paraffin wax flowers will play out. ⑦ nails: fingernails dug into paraffin blocks, pure beeswax stick nails, no white printing; mixed with paraffin wax slippery, non-stick nails, and appear white printing. ⑧ pull twist: Take a small piece of beeswax and gentle with your fingers, pinch the two twisted into thin strips pull out. Pure beeswax is easy to pull off, decapitated and tidy, the two coincide, easy to twist together; mixed with paraffin wax, pull elongation, fractured decapitated with a sharp, two less than a coincidence twist together. ⑨ fire: the small pillow melting wax directly on the fire, pure beeswax beads pillow melting wax dripping wax paper was flaky, uniform thickness; drops of toilet paper on the toilet paper does not dip, no miscellaneous slag; drop people into the water uniform thin, transparent, hand twist not brittle. Adulterated beeswax wax droplets on the toilet paper piles, impregnated paper, and the emergence of grunge circle; drops mixed with starch also piles of paper, there are obvious miscellaneous slag; wax beads as drops of water people, solidified blocks into a butterfly wax-like flowers, while thick and thin in the middle with a sharp, opaque, hand twist that is broken (Table i2) 0
