Soy Paper Vs. Seaweed – A Comparison Guide

A selection of sushi top down

Sushi enthusiasts may already be familiar with nori, the seaweed paper used as a food wrap. Although not commonly seen at sushi restaurants, there are alternatives to nori, such as soy paper.

But how do they compare, and can they be used in the same way? We’ve created the ultimate comparison of soy paper and seaweed wrap to help you decide which is best for you. Let’s get started.

What’s the difference between soy paper and seaweed?

Soy paper is a delicate, thin wrapper with a neutral flavor and aroma. Made from soybeans, it can replace seaweed paper in sushi but is also useful for dessert wraps and spring rolls. Seaweed paper, or nori, is only used for sushi. The dark green sheets have a mild aroma and flavor of the sea.

Soy paper has no flavor or aroma, so it’s a great option for picky eaters. It will also allow the other ingredients to be the hero of the plate. The paper’s texture is thin and flexible, a lot like rice paper rolls.

Seaweed paper has a subtle “fishy” smell and taste that some people don’t enjoy. Its texture is also thin, but it’s also a little crispy. Although not everyone enjoys ingredients from the sea, most lovers of sushi agree that seaweed is the best tasting casing for sushi.


One of the benefits of using soy paper is that it comes in a range of colors including white, orange, green, yellow, and pink. Most brands use natural colors like turmeric to make yellow paper, paprika to make orange, and spinach to make green. Be sure to check the label though, if you don’t want artificial ingredients.

Nori is a dark green shade, which results from the use of the red algae genus Pyropia. If you want authentic-looking sushi, then this is what you’re best to use.

Culinary uses

Soybean and seaweed paper are both used for making sushi. They can roll up easily without breaking. Soybean paper has a few extra uses though, making a handy exterior for spring rolls and a type of “dumpling”. Thanks to its neutral flavor, you can also wrap sweet ingredients like fruit or even pudding in them.


Unopened nori will last 1-2 years if stored unopened in a cool, dry place. Once opened, it will last up to 3 weeks stored in the pantry. Make sure to store in an airtight container as the seaweed quickly absorbs any moisture in the air.

Packaged soy paper should last a similar duration to nori if unopened. From our experience, we found it doesn’t last as long as seaweed paper once opened. Expect it to last up to 2 weeks, stored in a cool, dry position.


The macronutrients breakdown of seaweed and soy paper is similar. They are both healthy ingredients suitable for a plant-based or gluten-free diet.

Soy paper has a higher calorie count but is lower in carbs. The difference would only be significant if you eat a lot of sushi though.

Seaweed paper is a healthier choice overall. It has higher counts of Omega-3, fiber, iodine, and magnesium.

Commonly asked questions

How do I make soy paper stick to the rice?

Although soy paper rice can be a challenge to work with at first, you’ll find that sushi rice makes life easier. A few drops of water on the edge of the soy paper combined with firm pressure should allow you to hold everything in place.

What can I use as a substitute for soybean paper?

If you don’t have soy paper, your best alternatives are nori or rice paper. Another useful vegetarian option is to thinly slice cucumber and use it to roll up your favorite fillings.

Soy paper and seaweed paper are both healthy, gluten-free options for wrapping up sushi. If you enjoy authentic Japanese cuisine, then seaweed (nori) is a great choice.
