Application of Flavors in Frozen Drinks
1. Definition and Categories
According to the current National Food Safety Standard for Frozen Drinks and Production Ingredients, frozen drinks refer to solid or semi-solid foods made from several of the following main raw materials: drinking water, sugar, milk, dairy products, fruit and vegetable products, beans, edible oils and fats, with or without other auxiliary materials, food additives, and food nutrition fortifiers, through processes such as batching, pasteurization or sterilization, freezing or congealing.
Common categories include: ice cream, ice lolly, slush, popsicle, sweet ice, edible ice, etc.

3. Flavoring Timing for Frozen Drinks
(1) Flavoring Process
Flavoring is usually carried out in the feed liquid of the aging tank.
(2) Temperature Control
The most suitable and standard aging temperature is usually controlled between 0°C and 4°C; in actual production, the most common and efficient aging temperature is 2°C to 6°C.
(3) Flavoring Timing
Generally, flavors are added half an hour after the feed liquid is fully aged and before entering the congealing or molding process to ensure stable aroma and natural fragrance retention.
(4) Flavoring Notes
-
The stirrer in the aging tank should be turned on simultaneously during flavoring to ensure uniform dispersion.
-
Emulsified flavors should not be added at the same time as water-based or water-oil dual-purpose flavors.
-
Water-based/water-oil dual-purpose flavors should be added first, stirred evenly, and then emulsified flavors should be added to avoid demulsification, flocculent precipitation and other problems.

4. Basic Principles for Selecting Flavors for Frozen Drinks
(1) Selection of Flavor Type and Form
Edible sweet flavor is preferred. The company’s sweet water-based flavors, water-oil dual-purpose flavors, emulsified flavors and powder flavors are all suitable for frozen drinks, and water-oil dual-purpose flavors are the first choice.
Frozen drinks generally have low requirements on the temperature resistance of flavors.
(2) Selection and Promotion on Demand
According to the product types such as ice cream, ice lolly and popsicle, combined with the customer’s process and flavor requirements, select the corresponding flavor from the company’s sweet flavor series for sample delivery and promotion.
(3) Recommended Dosage

5. Common Product Quality Problems and Main Causes in Frozen Drink Enterprises
(1) Taste Defects
Coarse ice crystals: Insufficient aging time, improper congealing operation, or fluctuations in cold chain temperature.
Fat floating and whey separation: Insufficient homogenization.
-
Aging temperature: 2°C – 6°C
-
Aging time: 2 hours ≤ aging ≤ 48 hours
-
Homogenization temperature: 65°C – 75°C
-
Homogenization pressure: 13 – 20MPa
(2) Structural Deformation
Shrinkage and collapse: Insufficient hardening temperature/time, unreasonable proportion of dry matter, or improper selection of stabilizers.
(3) Abnormal Flavor
Aroma volatilization and deterioration: Improper timing or temperature control of flavor addition.
Unstable flavor: Fluctuations in raw material quality.
(4) Excessive Microorganisms
Incomplete sterilization, inadequate CIP cleaning of equipment, or cold chain breakage.
-
Pasteurization for milk-containing formulas: 82°C – 85°C
-
Sterilization for non-milk formulas: 85°C – 90°C
-
Sterilization time: 20 – 60 seconds
