Sorbitol
Manufactured by Maclin Biochemical Technology
Sourced in China
Sorbitol is a sugar alcohol commonly used as a sweetener in various food and pharmaceutical products. It is a white, crystalline powder that is naturally found in many fruits and berries. Sorbitol has a sweet taste and is often used as a replacement for sucrose in low-calorie and diabetic-friendly formulations due to its lower glycemic index. It is a versatile ingredient with applications in the production of candies, chewing gum, and other confectionery items.

Gluconobacter oxydans NL71 strain, derived from ATCC621, was stored in sorbitol-agar medium containing 50 g/L sorbitol, 5 g/L yeast extract, and 15 g/L agar under 4 °C. G. oxydans NL71 inoculum was cultivated in a 250-mL Erlenmeyer flask containing 50 mL of culture medium consisting of 100 g/L sorbitol and 10 g/L yeast extract, then incubated for 24–36 h at 30 °C and 220 rpm. The proliferative cells were harvested by refrigerated centrifugation (Avanti J26 XP, Beckman Coulter) at 6000 rpm for 5 to 10 min [31 , 32 (link)].
Biomass-based butanol, BA, sorbitol and sorbose were purchased from Macklin, while yeast extract was obtained from Sigma. All other chemicals such as nutrients and NaOH, were of analytical grade and were commercially available.

A total of 33 pesticide reference standards with initial concentrations of 100 µg/mL and purities of 98.0-99.9% were supplied by the Agro-Environmental Protection Institute, Ministry of Agriculture and Rural Affairs, China (see Table A1 in the Appendix). These pesticides were selected based upon their common application on tea plants and could be analyzed through GC-MS/MS. Primary secondary amine (PSA), graphitized carbon black (GCB), and C18 sorbents were purchased from Agela Technologies (Tianjin, China). HPLC grade acetonitrile and toluene were purchased from Sigma-Aldrich (Merck, Germany). Analytical grade sodium chloride (NaCl) and anhydrous magnesium sulfate (MgSO4) were purchased from China National Medicines Corporation Ltd. (Shanghai, China). Heptachlor epoxide with a purity ≥ 98.0% was used as an internal standard (IS) for GC-MS/MS analysis. The stock IS solution was prepared in acetonitrile to a concentration of 4 µg/mL and preserved at -20 °C until used. An analyte protectant (AP) solution was also prepared in acetonitrile, comprising 10 mg/mL of sorbitol and 20 mg/mL of L-gulonic acid-γ-lactone (both ≥ 98.0% purity; Macklin, Shanghai, China).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
