| identification test | shall conform to the infrared spectrum of fig. 14010. The analysis sample was melted and prepared on cesium bromide plate. Solubility is insoluble in water, soluble in acetone and benzene (0T-42). Resin ester and glycerol were tested according to GC method (GT-10). Sulfur test (test in the presence of tall oil resin) 40~50mg of sample is placed in a test tube, 1~2 drops of 20% sodium formate solution are added, a lead acetate test paper is wrapped in the test tube mouth, and the smoke in the test tube is in contact with the test paper, and then heated for 2~5min, no lead sulfide black spots are allowed (the detection limit is 50mg/kg sulfur). |
| toxicity | GRAS(FDA,§ 172.735,2000). |
| use limit | is limited to applicable in gum sugar; In beverages, it is limited to 100 mg/kg (FDA, 172.615, 172. 735,2000). GB 2760-1996(g/kg): Gum sugar ≤ 1.0; Emulsified essence ≤ 100.0 (equivalent to 0.1 g/kg in carbonated beverage). |
| use | plasticizer in gum base; Beverage stabilizer. Citrus oil suspending agent. as W/O food emulsifier. It can be used as emulsified essence with a maximum usage of 100 g/kg, which is equivalent to 0.1g.kg in carbonated beverage. The maximum usage in chewing gum base is 1.0 g/kg. |
| production method | refined rosin and glycerin are esterified in the presence of catalyst zinc oxide or calcium oxide and under the protection of nitrogen, the reactant is vacuumed to remove water vapor, and then further refined to obtain the finished product. It is made from light-colored wood rosin and edible glycerol. Used as a gum base, and then refined by steam stripping; used as a beverage stabilizer (adjust the density of citrus essential oils), refined by reverse steam distillation. Due to the bitterness of rosin glycerides, rosin was modified to produce hydrogenated rosin, polyrosin, and some dimeric rosin. The glycerides obtained from this are: hydrogenated rosin glycerides (hydrogenated ester gum), some dimeric rosin glycerides, poly rosin glycerides, tall oil rosin glycerides, these products are to a certain extent Improve the bitter taste of rosin glycerides and increase their use value in food. |
