How long can the brewed flower tea be stored for

It is recommended to consume the brewed flower tea within 2 hours at room temperature, and refrigerated storage can be extended to 24 hours. The deterioration of flower tea is mainly related to factors such as microbial growth, oxidation reactions, temperature changes, container hygiene, and raw material quality.

1. Microbial Breeding

Flower tea contains sugar and organic acids, and can easily breed bacteria and fungi if left at room temperature for more than 2 hours. Herbs such as chrysanthemums and roses are more prone to spoilage and may cause gastrointestinal discomfort after consumption. It is recommended to use a glass sealed jar for storage and avoid direct use by hand.

2. Oxidation Reaction

Polyphenolic substances such as jasmine tea are prone to oxidation when exposed to air, causing the tea soup to darken in color and lose its flavor. After oxidation, the medicinal components of honeysuckle tea will degrade. refrigeration can slow down this process, but it should not exceed 12 hours.

3. Temperature changes

Repeated heating can destroy the anthocyanins in hibiscus tea, and vitamin C in lemon slices quickly decomposes above 40 ℃. The storage temperature of the thermos should be controlled below 60 ℃, and it is advisable to drink it within 4 hours.

4. Container hygiene

Plastic cups are prone to residual tea stains and bacterial growth, while metal containers may cause some flower teas to discolor. Ceramics or glassware are preferred, and should be washed with boiling water before each use to avoid cross contamination of different types of flower tea.

5. Raw material quality

Osmanthus honey brewed flower tea with high sugar content has a shorter shelf life, and raw materials with insufficient dryness are prone to mold after soaking. It is recommended to choose sterilized packaging products from legitimate channels. For homemade flower tea, it is necessary to ensure that the raw materials are fully dried and dehydrated.

Before drinking, it is necessary to observe whether the tea soup is cloudy and whether there are any odors or floating objects. It is recommended to drink within 2 hours after quickly cooling with ice in summer, and it can be extended to 3-4 hours in winter. Overnight flower tea is not recommended to be consumed even if refrigerated, as the nitrite content may increase. More attention should be paid to the storage time when seasoning with honey or rock sugar. diabetes patients should strictly control the storage time. Small capacity tea sets can be used for daily brewing and drinking, ensuring flavor and avoiding waste.
