Rosemary Extract Product Introduction

Rosemary extract is a natural plant extract derived from the rosemary plant, with key components such as rosmarinic acid and rosmanol. It has various benefits including antioxidant, antibacterial, and anti-inflammatory properties. This extract is widely used in food, dietary supplements, and cosmetics. In food, rosemary extract can act as a natural preservative, extending shelf life; in dietary supplements, it's often associated with memory enhancement and immune support; and in cosmetics, it is commonly used in skincare products for its astringent and anti-aging effects. The extract's broad applicability makes it popular among consumers, praised for its natural and safe characteristics.

Rosemary Extract Production Process

The production process of rosemary extract typically includes the following steps:

  1. Raw Material Preparation: Select high-quality rosemary plants, including leaves and stems, which must be stringently screened and cleaned to ensure purity.
  2. Extraction: Add cleaned rosemary plants into an extraction vessel and use an appropriate solvent (such as ethanol or water) for steeping. The time and temperature for extraction must be controlled based on process requirements to fully extract effective components from the rosemary.
  3. Concentration: The extracted solution needs to be concentrated to remove excess solvent and increase the concentration of the extract. Low-temperature or vacuum concentration methods are typically used to preserve the extract's active ingredients.
  4. Filtration: The concentrated extract must be filtered to remove plant impurities and solid particles, resulting in a clear liquid.
  5. Crystallization: In some cases, to achieve a higher purity of the extract, crystallization methods may be used for further purification.
  6. Drying: Finally, the extract undergoes drying to remove residual moisture, yielding dry rosemary extract. Techniques such as spray drying or vacuum drying may be employed.
  7. Packaging: The dried rosemary extract needs to be packaged in airtight containers to prevent external contamination and moisture exposure.

Each step of the rosemary extract production process must be strictly controlled to ensure product quality and stability.

Rosemary Plant Information: Source, Distribution, and Growth Environment

Rosemary (Scientific Name: Rosmarinus officinalis) is a common perennial herb belonging to the Lamiaceae family. Here’s detailed information about the rosemary plant from which the extract is derived, including its characteristics, distribution, and growth conditions:

  1. Plant Characteristics:
  • Rosemary appears as a bushy plant with upright, multi-branched stems, typically reaching heights of 1-2 meters. Its leaves are needle-like, leathery, elongated, and possess a strong fragrance. The small purple flowers gather at the tops of branches or leaf axils, blooming from spring to summer.
  1. Distribution:
  • Native to the Mediterranean region, rosemary is mainly found in Southern European countries along the Mediterranean, such as Spain, Italy, and Greece, as well as North African countries like Morocco. It is also widely cultivated in temperate and tropical regions around the world.
  1. Growth Environment:
  • Rosemary thrives in warm and dry climates and is well adapted to sunny, well-drained soils. It typically grows in coastal areas, on hillsides, and in rocky soils, at altitudes ranging from sea level to about 1,500 meters. It is quite resilient to drought and poor soil conditions, flourishing to form dense thickets when conditions are favorable.
  1. Cultivation:
  • Rosemary is best cultivated in sunny, warm areas. When cultivating, choose well-drained, loose, and fertile soil, and prune annually in spring to encourage new growth. Rosemary can also be cared for as a potted plant, placed in bright outdoor settings or sunny indoor locations.

The rosemary plant is not only valued for its ornamental beauty but also as an important medicinal herb. Its aromatic leaves and flowers are used to create seasonings, medicines, and cosmetics. Under suitable growing conditions, rosemary can flourish, providing abundant medicinal and aromatic resources.

Processing and Storage of Rosemary Extract

The processing of rosemary extract involves several steps: harvesting fresh leaves or flowers of the rosemary plant, washing and air-drying them, followed by employing suitable extraction methods (such as steam distillation or supercritical fluid extraction) to obtain the desired constituents, resulting in rosemary extract. During storage, it is important to avoid direct sunlight and humid environments, selecting a dry, cool, and well-ventilated space to extend its shelf life. It is generally recommended to store in sealed containers to minimize air exposure, ensuring product quality and stability.
