Guide to the efficient application of double concentrated tomato paste in stews

Double Concentrated Tomato Paste has become a "secret weapon" for professional chefs to improve the quality of stews due to its rich flavor and efficient coloring and thickening properties. Its lycopene content is 2.5 times that of ordinary tomato paste, and the flavor intensity per unit volume can reach 3 times that of ordinary products.
1. Pretreatment process: Stir-frying tomato paste with oil is a key step to unleash its potential. It is recommended to use olive oil or animal fat and stir-fry at a medium-low temperature of 120-140℃ for 3-5 minutes. This process can form a fat-soluble complex between lycopene and oil, increase bioavailability by 40%, and produce more than 30 volatile aromatic substances.
Caramelization control: When a golden brown film appears on the bottom of the pot (professionally called fond), immediately add a small amount of liquid (water/broth) to deglaze. The complex flavor substances formed at this time can enhance the depth of the stew. Experimental data show that this step can increase the content of umami glutamate by 18%.
2. Precise dosage and dilution formula
Concentration conversion model:
Ordinary tomato paste dosage × 0.5 = double concentrate dosage + equal liquid compensation
Example: The original formula requires 30g of ordinary tomato paste, which is replaced with 15g double concentrate + 15ml of water
Gradient addition method:
Base layer: 60% of the total amount is added in the initial stage
Correction layer: 40% is added 20 minutes before the end of stewing. This method can not only ensure the flavor base, but also avoid the sourness imbalance caused by long-term stewing. Sensory tests have shown that the flavor layering can be improved by 27%.
3. Acid-base balance equation
The pH value of double concentrated tomato paste is about 3.9-4.2, and an acid-base buffer system needs to be established:
Carbohydrate neutralization: Add 2-3g sucrose/honey per 100g tomato paste to reduce the sourness without increasing the sweetness
Cream buffer: Add 20% fresh cream or 5% sugar-free yogurt to raise the pH value to the comfortable zone of 4.5-5.0
Umami synergy: 0.1% yeast extract or 1% Parmesan cheese powder, enhance the overall flavor roundness through 5'-nucleotides
4. Texture control technology
Starch-pectin composite system:
Stewed with root vegetables (carrots/potatoes), the released amylose can form a stable gel with tomato pectin
Adding 0.5% cassava starch or 0.3% xanthan gum can construct a high-temperature resistant pseudoplastic fluid structure Experiments have shown that this method improves the stickiness of the sauce by 35% and the stability of the texture after cooling by 50%
V. Equipment Adaptation Solution
Pressure cooker environment: reduce the amount by 20%, control the time to 8-10 minutes, and avoid excessive hydrolysis and bitterness
Slow cooker environment: seal and stir-fry in the initial stage and then transfer, and add 5% liquid every 2 hours in the later stage
Induction cooker application: maintain the power range of 800-1000W, and use a silicone spatula to scrape the bottom and stir every 15 minutes
