Is Soy Sauce Halal? Detailed Analysis

Soy sauce is a popular condiment used across many cuisines around the world. However, for Muslims who follow Islamic dietary laws, the halal status of soy sauce is often unclear due to the ingredients and production process involved. Let’s see how to determine if soy sauce is halal.

The Qur’an outlines certain permissible and impermissible foods and drinks for Muslims. This is collectively known as halal dietary restrictions. Soy sauce is a gray area because it may contain small amounts of alcohol from the fermentation process. The aim here is to examine the different types of soy sauce and evaluate their halal status based on certificationingredients and production methods.

Traditional Soy Sauce Production

Traditional soy sauce is brewed from soybeanswheat, salt and water. This mixture undergoes lactic acid fermentation and yeast fermentation, which can result in up to 2-3% alcohol content. Variants include:

  • Koikuchi (Japanese dark soy sauce)
  • Usukuchi (Japanese light soy sauce)
  • Tamari (wheat-free)
  • Shoyu (equal parts soybeans and wheat)

Alcohol Content

  • Scholars disagree on whether such tiny amounts make it haram
  • Some bodies permit it since alcohol is not added deliberately

Non-Traditional Soy Sauce

Modern methods skip fermentation and use acid hydrolysis of soy protein and corn syrup. This produces no alcohol but does use additives:

  • HVP (hydrolyzed vegetable protein)
  • Caramel coloring
  • Preservatives like sodium benzoate

Checking for Halal Certification

  • Reputable bodies have stringent guidelines
  • Kosher ≠ halal – different religious requirements
  • Check for halal symbols or labels stating:
    • Ingredients
    • Production process

Halal-Certified Soy Sauce Brands

Soy VayNo alcohol, made from soybeans and water only
KikkomanTamari and shoyu varieties certified by IFANCA

Non-Halal Soy Sauce Alternatives

  • Liquid aminos – made from coconut tree sap
  • Coconut aminos – no soy or wheat

These have different taste but avoid alcohol.


Checking certificationingredients and production is key to verifying halal status. For Muslims seeking to incorporate soy sauce, tamari and certified brands are the best option. Alternatives like liquid aminos also exist. Care must be taken to avoid non-halal varieties.
