Preservation — Process Challenge

酸化防止剤:油脂・揚げ菓子の酸敗対策

油脂、スナック衣粉、ドライミックスに含まれる不飽和脂質がラジカル自動酸化を起こし、過酸化物と酸敗による異味・異臭を生じるため、製品まで持続性を持つ連鎖切断型酸化防止剤が必要

ソリューションアプローチ

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow
1
Process & Compliance Review
Map the application and contact points, and confirm food-grade and regulatory status (FCC/USP, Kosher/Halal, allergen) for every input.
2
Ingredient & Grade Selection
Select the right grade of acidulant, preservative, emulsifier, stabilizer, or processing aid for the formulation, label, and sensory targets.
3
Bench Trial & Dosing
Validate use level and performance in a bench or pilot batch, and specify packaging and lot traceability suited to food-safety requirements.
4
Quality & Shelf-Life Validation
Verify finished-product quality, microbial stability, and shelf life, and lock the spec with a CoA and document control for audits.
Recommended Chemistries (8)
BHA (Butylated Hydroxyanisole), Food Grade
CAS 25013-16-5
特殊添加剤
防腐
Butylated hydroxyanisole donates a phenolic hydrogen to lipid peroxyl radicals, interrupting propagation; it pairs synergistically with BHT and TBHQ in oils and snack coatings
融点:48–55 °C   沸点:264–270 °C at 733 mmHg   Solubility: < 1 mg/mL at 18 °C

詳細情報
BHT (Butylated Hydroxytoluene), Food Grade
CAS 128-37-0
特殊添加剤
防腐
The hindered-phenol OH quenches peroxyl radicals to halt the autoxidation chain that turns fats and fried snacks rancid
融点:69–71 °C   沸点:265 °C at 760 mmHg   密度:1.048 at 20 °C

詳細情報
TBHQ (Tert-Butylhydroquinone), Food Grade
CAS 1948-33-0
特殊添加剤
防腐
TBHQ's dihydroxybenzene ring scavenges peroxyl radicals and carries unusually well through high-temperature frying into the fried product
融点:127–129 °C   沸点:295 °C at 760 mmHg   密度:1.05

詳細情報
Propyl Gallate (NF/FCC)
CAS 121-79-9
溶解力
Gallate ester both chelates trace metals and donates phenolic hydrogens, lengthening induction time; commonly blended with BHA for lower-temperature systems

詳細情報
Mixed Tocopherols Powder (Natural Antioxidant)
CAS 1406-66-2
特殊添加剤
防腐
Tocopherols donate H to lipid radicals to break the autoxidation chain, giving a label-friendly antioxidant for oils and emulsions
沸点:Decomposes   Solubility: Insoluble

詳細情報
Mixed Tocopherols Oil (Natural Antioxidant)
CAS 10191-41-0
特殊添加剤
防腐
Liquid mixed tocopherols disperse into fats and oils to scavenge radicals at the lipid phase
融点:2.5-3.5 °C   沸点:BP: 200-220 °C at 0.1 mmHg   密度:0.950 at 25 °C/4 °C

詳細情報
D-Alpha Tocopherol Powder (Vitamin E)
CAS 59-02-9
特殊添加剤
防腐
Alpha-tocopherol interrupts lipid peroxidation as a natural-source chain-breaking antioxidant
融点:3 °C   沸点:BP: 210 °C at 0.1 mm Hg   密度:0.950 g/cu cm at 25 de C

詳細情報
Ascorbyl Palmitate
CAS 137-66-6
Oil-soluble ascorbate ester (E304) engineered for lipid systems; genuine tocopherol synergist that regenerates spent chain-breaking antioxidants directly in the frying-oil/fried-snack lipid phase. Partitions into the oil, so it actually protects the target matrix. Correct fit for rancidity control in fats/oils/fried snacks.
