Where to Store Tomato Paste for Freshness and Safety Guide

A Practical Storage Guide for Industrial and Commercial Buyers

Tomato paste storage requirements vary significantly depending on packaging type. While small household packs are designed for short-term use, industrial and foodservice packaging such as drums or bulk cans require stricter handling and storage controls to maintain product safety and quality.

This guide explains how to store tomato paste correctly based on its packaging, covering unopened and opened conditions, realistic shelf life expectations, and best practices used by food manufacturers and processors.

1. Drum Tomato Paste Storage (220L Aseptic Drums)

Typical users:
Food processing plants, repackers, sauce manufacturers

Unopened Drum Storage

• Store in a cool, dry, and well-ventilated indoor warehouse
• Avoid direct sunlight and heat sources
• Keep drums upright and off the ground using pallets
• Normal shelf life: 18–24 months under proper conditions

Opened Drum Storage (Critical)

Once an aseptic drum is opened, it is no longer sterile and must be handled carefully.

Best practices after opening:

• Transfer tomato paste immediately into clean food-grade storage containers
• If indoor storage is available:
  • Store in a cool, shaded, ventilated room
• If indoor storage is not available:
  • Place drums outdoors only in dry weather
  • Cover the drum opening tightly with plastic film or waterproof membrane
  • Prevent rainwater, dust, or insects from entering

Important:
Opened drum tomato paste is intended for rapid industrial use, not long-term storage. Use as soon as possible to reduce microbial risk.

2. Canned Tomato Paste Storage

Unopened Canned Tomato Paste

• Store in a food pantry or dry storage room
• Shelf life: 18–24 months
• Always inspect cans before use:
  • No dents
  • No swelling
  • No rust or leakage

Any can showing deformation or bulging should be discarded.

Opened Canned Tomato Paste

Once opened, tomato paste must never be stored in the metal can.

Refrigeration (Correct Method)

• Transfer paste into a glass or BPA-free plastic container
• Cover the surface with plastic wrap to minimize air exposure and odor absorption
• Refrigerate at ≤4°C (≤40°F)
• Shelf life: 4–5 days

Refrigeration (Incorrect Method)

• Left exposed
• Stored in original can
• Not sealed properly

Shelf life in this case drops to 2–3 days due to oxidation and contamination.

3. Frozen Tomato Paste Storage (By Method)

Freezing is an effective way to extend shelf life after opening, especially for foodservice use.

Best practices:

• Remove as much air as possible before freezing
• Label with production or freezing date
• Thaw only the required portion to avoid repeated freeze-thaw cycles

4. Tube-Pack Tomato Paste Storage

After Opening

• Squeeze out excess air before resealing
• Ensure the cap is tightly closed
• Store in the refrigerator

Shelf life:
7–10 days when properly resealed and refrigerated

Tube packaging offers better oxidation control than cans, making it suitable for repeated short-term use.

5. Bottled Tomato Paste Storage

• Always tighten the cap securely after use
• Store in the refrigerator after opening
• Avoid cross-contamination by using clean utensils

Shelf life depends on formulation and preservatives but generally aligns with 5–7 days once opened.

6. Key Storage Takeaways by Packaging Type

• Drum tomato paste is designed for industrial environments and must be transferred and protected immediately after opening
• Canned tomato paste offers long unopened shelf life but requires proper container transfer after opening
• Freezing extends usability, but storage duration varies by method
• Tube and bottle packaging provide better short-term convenience with controlled exposure
