Frequently Asked Questions about Stainless Steel Vacuum Insulated Food Jars
Q1: How long do stainless steel vacuum insulated food jars keep food hot or cold?
A1: The duration varies significantly by brand and model, but generally, hot food can stay warm for 5 to 14 hours, and cold food can stay chilled for 7 to 24 hours. Always check the specific product’s specifications for exact times.
Q2: Are these food jars safe to use? Are they BPA-free?
A2: Yes, high-quality stainless steel vacuum insulated food jars are generally very safe. Most are made from food-grade 18/8 stainless steel, which is rust-resistant and doesn’t leach chemicals. Reputable brands like Thermos and Stanley confirm their products are BPA-free.
Q3: Can I put soup in a vacuum insulated food jar?
A3: Absolutely! These jars are perfect for soups, stews, chili, and other liquid-based meals. Their leak-proof design ensures no spills, and the vacuum insulation keeps your soup hot for hours.
Q4: How do I pre-heat or pre-chill my food jar for best results?
A4: To maximize temperature retention, pre-heat your jar by filling it with boiling water for 5-10 minutes, then emptying it before adding hot food. For cold food, pre-chill with ice water for 5-10 minutes before adding your chilled meal. This helps prevent the jar from absorbing the food’s initial temperature.
Q5: Are stainless steel food jars easy to clean?
A5: Most modern stainless steel food jars are designed with wide mouths, making them easy to hand-wash. Many are also dishwasher safe (usually top rack recommended), but always check the manufacturer’s instructions for the best cleaning method to ensure longevity.
Q6: Can I microwave food directly in these jars?
A6: No, you should never put a stainless steel food jar in the microwave. Stainless steel is metal and will cause sparks and damage to your microwave. Always heat your food separately and then transfer it to the pre-heated food jar.
Q7: What’s the difference between 18/8 and 18/10 stainless steel in food containers?
A7: Both 18/8 and 18/10 stainless steel are food-grade. The numbers refer to the chromium and nickel content (18% chromium, 8% or 10% nickel). Both are durable and corrosion-resistant. 18/10 has slightly more nickel, making it a bit more resistant to corrosion and giving it a shinier finish, but 18/8 is perfectly safe and suitable for food containers.
