The main cause of food deterioration during processing, transportation and storage is lipid oxidation, and the addition of antioxidants is the main means of delaying the oxidation of oil and fat products. Antioxidant is a free radical trapping agent, when it plays an antioxidant role, it can provide active hydrogen to combine with free radicals generated during oxidation of fats and oils, so that the free radicals are converted into stable compounds, blocking the free radical chain reaction, inhibiting lipid peroxidation, slowing down the oxidation of fats and oils and deterioration.

At high temperatures, a series of complex chemical reactions such as oxidation, decomposition, polymerization, and hydrolysis are prone to occur, resulting in a rapid increase in the acid value, peroxide value, and carbon base value of roasted foods. In the later stage of storage and sales, unpleasant odors are easily produced. The use of TBHQ can effectively delay oil oxidation in pastry foods.However, the oxidation and rancidity of fats and oils, as well as the production of unpleasant flavors, are a problem that troubles many pastry food producers.

With the development of the food industry, the forms of pastry food have become diverse. The various oils and fats used in pastry are essential ingredients. Oil, with its good crispness and unique flavor, has become one of the three major ingredients in baked goods. It plays an irreplaceable role in the production process of pastry food and is also an important source of energy for consumers. However, the oxidation and rancidity of fats and oils, as well as the production of unpleasant flavors, are a problem that troubles many pastry food producers.

When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides. When citric acid is combined with antioxidants, the higher the content of these impurities in the oil, the more obvious the synergistic effect. TBHQ has good oil solubility and thermal stability, and does not change in color after heating.The process of adding oil is complex, and it is easy to precipitate or oxidize during placement. Therefore, they should not be used as advanced oil antioxidants.

Pastry and bread stored in the air for a long time are prone to spoilage due to oxidation of their lipid components. The oxidation of oil components not only causes food discoloration, discoloration, destruction of vitamin A, D, E, and other components, but also produces odor. In addition, essential fatty acids such as linoleic acid and linolenic acid in oil are also damaged, reducing the nutritional function of the product. In severe cases, harmful substances such as oxides, peroxides, and decomposition products such as epoxypropylaldehyde can be produced, leading to food poisoning.

Application cases of TBHQEdible oils and fats: Adding TBHQ to edible oils and fats can effectively slow down the rancidity process and prolong the shelf life of food. In practical application, TBHQ is usually added directly into oils and fats in the form of powder or liquid, and the usage amount is usually 0.01% to 0.02%.Meat products: Adding TBHQ to meat products can extend shelf life and prevent bacterial contamination and oxidative deterioration.
Shandong Best Each Ships High-Quality DTBHQ to Shanghai, Helping Industrial Sector to Achieve Another Successful Result Ltd. has successfully shipped a batch of high quality 2,5-Di-tert-butylhydroquinone (DTBHQ) to Shanghai, demonstrating once again its strong production capacity and in-depth layout of the market.
DTBHQ and TBHQ are two food additives that are somewhat similar in function, but also differ in chemical structure and application areas. Let's take a look at the differences between these two food additives.First of all, there are differences in the chemical structures of DTBHQ and TBHQ, whose full name is Di-Tert-Butylhydroquinone, a di-tert-butylhydroquinone, and TBHQ, whose full name is Tert-Butylhydroquinone, also a hydroquinone, but it has only one tert-butyl group.
TBHQ is a new synthetic antioxidant with good antioxidant effect, especially for vegetable oil antioxidant, has a very good anti-corrosion effect, is internationally recognized as one of the best food antioxidants.Benefits of using TBHQ in food:Good antioxidant effect, added to food can prevent food spoilage and odor, and well prolong the shelf life of food; in addition, it has anti-mold and anti-bacterial effects that other antioxidants do not have, and can effectively inhibit the growth of bacteria such as Bacillus subtilis, Staphylococcus aureus, Escherichia coli and other microorganisms su
TBHQ, also known as Tert-Butylhydroquinone, is a food additive that is a synthetic chemical widely used in the food industry to extend the shelf life of foods and prevent oxidation.TBHQ is produced by reacting hydroquinone with tert-butyl alcohol to produce TBHQ, a process that uses advanced technology and strict controls to ensure the high purity and stability of the product.The multiple uses of TBHQ in the food industry are mainly for preventing the oxidation of fats and oils during food processing and storage, thus extending the shelf life of food products.
Terbutylhydroquinone has good antioxidant effect. It has no bad taste and odor when added to any oil and oil-containing food. Good oil solubility, low toxicity, low dosage, it belongs to safe A(1) products, the antioxidant capacity is greater than propyl gallate (PG), 2,6-di-tert-butyl-p-cresol (BHT), tert-butyl-p-hydroxyanisole (BHA); added to food without bad odor.
Precautions for use 1. The amount and proportion of terbutylhydroquinone used should be strictly controlled and should not exceed the maximum amount specified.2. Terbutylhydroquinone should be used in acidic medium, avoid mixing with alkaline substances.3. Terbutylhydroquinone should be stored in a cool and dry place, avoiding direct sunlight and high temperature environment.4. butylhydroquinone should be stored in stainless steel or glassware when in direct contact with food, avoid using plastic containers.5.
