Sodium Stearoyl Lactylate (E481)-Emulsifier
Oct 20, 2022
Sodium Stearoyl Lactylate?
Sodium stearoyl lactylate los yog Sodium stearoyl-lactylate, tseem hu ua SSL (cov ntawv luv), nws yog sodium ntsev ntawm stearic acid nrog lactic acid dimer. Cov khoom xyaw no feem ntau yog siv los ua ib qho emulsifier thiab stabilizer nyob rau hauv high-fat bakery thiab nrog European zaub mov additive tooj E481.
Sodium Stearoyl Lactylate (SSL) ua li cas?
SSL yog tsim los ntawm cov zaub mov qib stearic acid (feem ntau los ntawm xibtes roj), lactic acid (los ntawm fermentation ntawm qab zib beet los yog tshuaj synthesis) thiab sodium hydroxide.
FDA tau hais tias SSL tuaj yeem tsim los ntawm esterification ntawm stearic acid thiab lactic acid los tsim stearoyl lactylic acid thiab tom qab ntawd neutralized rau hauv sodium ntsev nrog sodium hydroxide.
• Kev sib xyaw: sib tov aqueous stearic acid (tswj qhov kub siab tshaj nws qhov taw tes solidification) nrog aqueous lactic acid
•Neutralization: ntxiv sodium hydroxide rau qhov sib tov thiab cov tshuaj tiv thaiv neutralization yuav tshwm sim ntawm sodium hydroxide thiab lactic acid
Siv & Muaj nuj nqi
Sodium stearoyl lactylate feem ntau yog siv rau nws cov emulsifying thiab stabilizing zog hauv cov zaub mov. Hauv cov zaub mov, SSL sib tov dej thiab roj ua ke thiab feem ntau yog siv los ua lub khob noom cookie ntxiv dag zog thiab crumb softener hauv bakery.
SSL feem ntau yog siv rau hauv cov roj siab & cov poov xab-leavened qhob cij ua lub khob noom cookie txias / emulsifier rau lub hom phiaj ntawm:
• Ua kom cov hmoov nplej ntxiv: nce ntim thiab tau txais cov qauv zoo dua
• Crumb softening: interacts nrog hmoov los tsim gluten proteins / starch / lactylate complex uas tsim ib tug mos thiab elastic qhob cij thiab tiv thaiv qhob cij retrogradation (aging)
Nws kuj yog siv rau hauv ncuav qab zib, crackers, pastries, noodles, thiab cov zoo li los txhim kho cov kev ntxhib los mos, qhov ncauj xav thiab ncua lub freshness los yog txee lub sij hawm. Hauv cov ncuav qab zib thiab cracker, SSL yog siv los faib cov shortening uniformly hauv lub khob noom cookie.
SSL tuaj yeem ncaj qha ntxiv rau cov hmoov nplej los yog sib cais hauv dej sov thiab tom qab ntawd muab cov hmoov nplej sib xyaw rau kev siv.
Daim ntawv thov tus nqi raws li FDA:
• Cov khoom ci, pancakes, thiab waffles 0.5%
• Icings, filling, puddings, thiab toppings 0.2%
• Haus kas fes hloov mis los yog qab zib 0.3%

• Cheese hloov thiab imitations 0.2%
• Sauces los yog gravy 0.25%
• Cov dej qab zib liqueur 0.5%
European Food Safety Authority (EFSA)
Sodium stearoyl lactylate (E481) yog teev nyob rau hauv Commission Regulation (EU) No 231/2012 raws li kev tso cai zaub mov additive thiab categorized nyob rau hauv "Additives uas tsis yog xim thiab sweeteners".
