Posted On: 2024-04-17 UniVOOK Chemical

UniVOOK Chemical specializes in crafting high-purity Butylated Hydroxyanisole (BHA), tailored to meet diverse industry needs, including customized concentrations of the 3-BHA isomer. Our commitment to delivering up to 99% purity of 3-BHA ensures the adaptability and quality of our products for various applications.

Antioxidants play a vital role in preserving the freshness and stability of food and feed items, extending shelf life, and maintaining nutritional value. BHA serves as a potent antioxidant in these sectors, safeguarding against oxidation and rancidity in fats, oils, and other susceptible components. Its incorporation enhances product integrity and safety, significantly contributing to the longevity of consumables.

Chemical Structure and Properties of BHA

UniVOOK Chemical stands as a premier global manufacturer of Butylated Hydroxyanisole (BHA), catering to industries spanning food, feed, cosmetics, pharmaceuticals, and packaging materials. We offer Food grade, USP grade, NF grade, and Feed grade products, ensuring the highest standards of safety through our proprietary production method, which eliminates toluene from the process.

Molecular Structure

BHA comprises the isomers 2-tert-Butyl-4-methoxyphenol (2-BHA) and 3-tert-butyl-4-methoxyphenol (3-BHA), derived from Monomethyl Ether Hydroquinone (MEHQ). This stable compound plays a crucial role across various industries.

Physical Properties

BHA typically manifests as a white or slightly yellow waxy solid with a faint odor. It melts within a temperature range of 48°C to 63°C and demonstrates limited solubility in water, yet it dissolves more readily in organic solvents like ethanol and acetone.

Chemical Properties

With its phenolic structure, BHA serves as a potent antioxidant, effectively scavenging free radicals to prevent the oxidative degradation of fats, oils, and other susceptible materials. Its benefits extend to preserving the freshness and stability of various products.


BHA exhibits remarkable stability, enduring high temperatures during processing and retaining antioxidant efficacy over extended storage periods. This characteristic ensures prolonged shelf life for products containing BHA.

UniVOOK Chemical’s innovative production processes and efficient supply chain management enable us to offer BHA products with significant cost advantages globally, all while maintaining unwavering quality standards.

Mechanism of Action

Antioxidant Activity

BHA displays robust antioxidant properties by hindering the oxidation process of fats and oils. This entails neutralizing free radicals, highly reactive molecules initiating chain reactions leading to oxidative harm. By contributing hydrogen atoms or electrons to free radicals, BHA effectively disrupts these chain reactions, averting the formation of detrimental oxidation by-products. This antioxidant prowess safeguards the freshness and stability of diverse food and feed items, elongating their shelf life and sustaining their nutritional integrity.

Radical Scavenging

A primary function of BHA is radical scavenging. Free radicals, possessing unpaired electrons, are profoundly reactive and capable of instigating cellular harm. Acting as a scavenger, BHA interacts with these free radicals, neutralizing them and forestalling further harm. By intercepting free radicals, BHA interrupts the cascade of oxidation reactions, shielding delicate components in food and feed from deterioration.

Chain Breaking

BHA operates as a chain-breaking antioxidant, impeding the progression of lipid oxidation. Lipid oxidation, instigated by free radicals attacking unsaturated fatty acids in fats and oils, is a multifaceted process. Once initiated, this process can perpetuate in a chain reaction, culminating in the generation of various harmful compounds. BHA disrupts this sequence by supplying hydrogen atoms or electrons to reactive intermediates, thus breaking the chain and staving off further propagation of oxidation. This chain-breaking mechanism preserves the caliber and durability of food and feed items, assuring their safety and effectiveness.

Utilizing BHA in the Food Sector

Ensuring the Longevity of Fats and Oils

In the realm of food preservation, Butylated Hydroxyanisole (BHA) stands out for its critical function in safeguarding fats and oils. It effectively combats oxidative rancidity, thereby prolonging the appeal and consumption viability of products rich in oils and fats like snack foods, baked goods, and cooking oils. By preserving these essential attributes, BHA plays an essential role in maintaining consumer contentment and ensuring food safety.

Defending Food Against Oxidative Harm

BHA’s role extends beyond the preservation of fats and oils, offering broad-spectrum protection against the oxidative spoilage of a diverse range of food products. Its application prevents the loss of flavor, color, and overall food quality in a variety of items from cereals to sweets. This defense is vital for retaining the marketability and consumability of food products.

Prolonging Food Shelf Life

Applying BHA is key to significantly enhancing the shelf life of perishable food products. It decelerates the oxidation process, facilitating longer storage durations, minimizing waste, and optimizing logistics. This aspect is particularly crucial in the global food market, where products frequently traverse vast distances before reaching consumers.

Regulatory Compliance and Permitted Uses

BHA’s incorporation into food products is meticulously regulated to safeguard consumer health. Authorities like the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) dictate specific allowable BHA concentrations in various food categories. Adhering to these guidelines is imperative for manufacturers to ensure the safety and legality of BHA usage.

BHA in the Animal Feed Industry

1.Enhancement as a Feed Supplement

Within the animal feed sector, BHA is esteemed for its role as an antioxidative additive, vital for preserving the nutritional integrity and energy content of feed. Incorporating BHA helps sustain feed quality over time, guaranteeing that livestock benefit from a consistent and nutritious diet.

2.Advancing Livestock Health

BHA’s antioxidative attributes extend significant benefits to livestock health, counteracting oxidative stress and bolstering immune response, growth, and overall vitality. This contribution is instrumental in promoting more effective and sustainable livestock farming practices.

3.Boosting Feed Quality and Stability

The capability of BHA to stabilize feed components and avert the deterioration of critical nutrients like fats and vitamins is indispensable for crafting premium animal feed. This ensures that feed remains tasty and nutrient-rich from the point of production to consumption, aiding in optimal livestock development and yield.

4.Guidelines and Regulations for Animal Feed

The inclusion of BHA in animal feed is subject to comprehensive regulatory oversight similar to its use in food. Regulatory bodies, including the FDA and the European Union, have set forth specific BHA concentration standards in animal feed to ensure the welfare of animals and, by extension, the health of humans consuming animal-derived products. Compliance with these standards is crucial for feed producers to maintain product safety and regulatory adherence.
