1. معايير التصنيع
Food-grade Polysorbate 80 destined for use as additive E433 must meet the purity specifications established by the Food Chemicals Codex (FCC) and referenced in FDA 21 CFR 172.840. These parameters are verified on every Certificate of Analysis (CoA):
| المعلمة | حدود درجة الغذاء | What It Indicates |
|---|---|---|
| رقم التصبن | 45-55 ملغ KOH/غ | Total ester content — confirms the correct degree of oleic acid esterification |
| رقم الحمض | ≤ 2.0 mg KOH/g | Free fatty acid level — elevated values signal hydrolysis during storage or manufacturing |
| رقم الهيدروكسيل | 65-80 ملغ KOH/غ | Residual hydroxyl groups — confirms correct ethoxylation extent (~20 EO units) |
| محتوى الأوكسي إيثيلين | 65.0–69.5% | Ethylene oxide incorporation — the defining parameter for surfactant functionality |
| محتوى الماء | ≤ 0.5% | Karl Fischer titration — moisture above 0.5% accelerates ester hydrolysis and microbial risk |
| Heavy Metals (as Pb) | ≤ 10 ppm | General purity — ensures no contamination from manufacturing equipment or raw materials |
| 1,4-ديوكسان | ≤ 10 ppm | Ethoxylation byproduct — removed by vacuum stripping during manufacturing |
Procurement tip: The Acid Number is the single most informative quick-check parameter. An elevated value indicates partial hydrolysis of the ester bond — the surfactant may still function, but free oleic acid can introduce off-flavors detectable in delicate products like vanilla ice cream or clear beverages. For full grade-by-grade specifications (food vs. pharma vs. industrial), see our Technical Specifications Guide.
2. تطبيقات معالجة الأغذية وحدود إدارة الغذاء والدواء الأمريكية
جميع الحدود أدناه لكل إدارة الغذاء والدواء الأمريكية 21 CFR 172.840. PS80 is one of the most broadly permitted polysorbates in food processing, covering 15 distinct applications from frozen desserts to poultry processing.
الحلويات المجمدة
آيس كريم، كاسترد مثلج، آيس ميلك، شربات فواكه. PS80 partially displaces milk proteins from the fat globule surface during freezing, enabling controlled fat destabilization. This partial coalescence creates a three-dimensional fat network that traps air cells for smooth mouthfeel and slows melt-down. The total polysorbate load in frozen desserts is capped at 0.1% — this includes PS80, PS65, or any combination.
| طلب | حد |
|---|---|
| Frozen desserts (alone or with PS65) | ≤ 0.1% of finished product weight |
المخللات ومنتجات المخللات
PS80 acts as a solubilizing and dispersing agent for spice oils (dill, turmeric, celery) in brine systems. Without PS80, these hydrophobic oils float to the surface, producing uneven flavor distribution and an unappealing oil slick. PS80 disperses them uniformly throughout the aqueous phase.
| طلب | حد |
|---|---|
| Pickles and pickle products | ≤ 500 ppm (0.05%) |
السمن النباتي والزيوت الصالحة للأكل
In fat-based systems, PS80 provides emulsification stability and improves creaming performance when the shortening is later used in batter preparation. Often blended with Polysorbate 60 — PS80’s liquid form (oleic acid) complements PS60’s solid form (stearic acid) for a balanced crystallization profile.
| طلب | حد |
|---|---|
| Shortenings and edible oils | ≤ 1.0% by weight (alone or with PS60) |
إضافات زيت الطعام المخفوق
PS80 stabilizes the air-cell interface in whipped vegetable-oil toppings, enabling high overrun and firm, non-weeping peaks. The 0.4% limit applies to the total polysorbate load (PS80 + PS60 + PS65 combined). For the standard Span-Tween whipped topping blend, see our دليل مُصنّعي منتجات سبان وتوين.
| طلب | حد |
|---|---|
| إضافات من الزيت النباتي المخفوق | ≤ 0.4% (alone or combined with other polysorbates) |
تركيبات مزيلات رغوة الخميرة
PS80 controls gas release during yeast fermentation by reducing surface tension at the air-liquid interface of foam bubbles. The limit applies at two levels: 4% in the defoamer formulation itself, and 4 ppm in the final yeast product after the defoamer is applied.
| طلب | حد |
|---|---|
| Yeast defoamer formulation | ≤ 4% by weight of defoamer |
| In finished yeast product | ≤ 4 ppm |
Cottage Cheese (Creaming Mixture)
Acts as a defoaming agent in the creaming mixture — prevents air pockets from forming during the mixing of curd with cream dressing, ensuring a smooth, uniform consistency.
| طلب | حد |
|---|---|
| Cottage cheese creaming mixture | ≤ 0.008% of finished product weight |
حلويات ومزيجات الجيلاتين
PS80 serves as a dispersing agent for dry powder mixes, ensuring rapid and uniform hydration when the consumer adds water. Without PS80, gelatin powder clumps and forms fish-eyes — partially hydrated lumps that resist full dissolution.
| طلب | حد |
|---|---|
| Gelatin desserts and mixes | ≤ 0.082% on a dry-weight basis |
صلصة الشواء
Functions as a surfactant and wetting agent for natural and artificial colors. BBQ sauce is a complex emulsion of tomato solids, vinegar, oil, and spices — PS80 prevents color migration and separation during shelf storage.
| طلب | حد |
|---|---|
| صلصة الشواء | ≤ 0.005% by weight |
كلوريد الصوديوم البلوري الخشن
PS80 acts as a crystal habit modifier during NaCl production. At 10 ppm, it influences the growth pattern of sodium chloride crystals, producing a more uniform crystal size distribution desirable for food-grade salt.
| طلب | حد |
|---|---|
| Coarse crystal sodium chloride | ≤ 10 ppm |
ماء سلق الدواجن
Added to scald water as a wetting agent during the defeathering process. PS80 reduces the surface tension of water, allowing it to penetrate feathers more effectively — resulting in cleaner feather removal with less mechanical damage to the skin.
| طلب | حد |
|---|---|
| ماء سلق الدواجن | ≤ 0.0175% in water |
فاصوليا خضراء متبلة معلبة
Solubilizes dill oil in the canning brine for even flavor distribution. Without PS80, dill oil floats as a separate phase, producing inconsistent flavor across cans in the same batch.
| طلب | حد |
|---|---|
| Canned spiced green beans (for dill oil) | ≤ 30 ppm |
Vitamin-Mineral Preparations
PS80 solubilizes fat-soluble vitamins (A, D, E, K) in aqueous delivery systems. The limit depends on whether calcium caseinate is present in the formulation — caseinate competes for the oil-water interface and affects PS80’s effective concentration.
| طلب | حد |
|---|---|
| بدون كازينات الكالسيوم | ≤ 300 mg per daily dose |
| مع كازينات الكالسيوم | 175–475 mg per daily dose |
الأطعمة الغذائية الخاصة
PS80 serves as an emulsifier in formulated meal replacements, medical foods, and weight-control products regulated under 21 CFR 105.
| طلب | حد |
|---|---|
| أطعمة غذائية خاصة | ≤ 360 mg per day |
Herbicide & Plant-Growth Regulator Adjuvants
Applied to growing crops as a wetting agent — PS80 reduces the surface tension of spray solutions, improving coverage and absorption of active ingredients on leaf surfaces. This application is exempt from tolerance (no residue limit) under 40 CFR 180.
| طلب | حد |
|---|---|
| Herbicide and PGR adjuvants (pre-harvest) | معفى من التسامح |

4. ملاحظات حول صياغة وتوريد منتجات وخدمات الشركات
- Synergy with Span 60: PS80 is rarely used alone in bakery and topping applications. Pair it with أحادي ستيرات السوربيتان (سبان 60) for a more densely packed interfacial film. The Span 60 (HLB 4.7) + PS80 (HLB 15.0) combination creates a wider HLB span than Span 60 + PS60, providing robust stability across a broader range of oil phases. See our دليل مُصنّعي منتجات سبان وتوين for blending ratios.
- Labeling requirements: All intermediate premixes containing PS80 must state the exact concentration so end-manufacturers can calculate the final dosage and verify compliance. Premixes labeled simply as “contains Polysorbate 80” without concentration data are not compliant with FDA labeling requirements for food additives.
- Storage & oxidative stability: The oleic acid moiety (C18:1) makes PS80 susceptible to oxidation at the double bond. Store in sealed HDPE containers at 15–30°C, away from direct light. For bulk storage exceeding 30 days, nitrogen blanketing is recommended. Oxidized PS80 develops a rancid, painty odor detectable even at low concentrations in delicate products like vanilla ice cream and whipped toppings. Monitor peroxide value quarterly for bulk inventories.
- Grade verification: Always confirm food-grade (FCC/USP) certification on the CoA. Industrial-grade PS80 may contain residual ethylene oxide above 1 ppm or 1,4-dioxane above 10 ppm — neither is acceptable for food use. Foodemul.com provides batch-specific CoA with every shipment.
- Dosage precision: Many PS80 limits are in the ppm range (30 ppm for green beans, 10 ppm for salt, 4 ppm for yeast). These low concentrations require pre-dilution or masterbatch preparation for accurate dosing in production. Direct addition of neat PS80 at these levels is not practically achievable.
