Malt Extract Product Introduction

Malt extract is an extract made from barley seeds through germination and fermentation. Its main components include polysaccharides, proteins, amino acids, B vitamins, and minerals. Malt extract is extensively used in the food, beverage, health supplements, and cosmetics industries. In food, it's often used as a flavoring agent, color enhancer, aroma booster, and sweetener, giving products a unique malt flavor and sweetness while enhancing their nutritional value. In beverages, malt extract can be used to make beer and malt drinks, adding flavor and nutrition. In the health supplement area, malt extract is used as a nutritional supplement, providing a rich source of B vitamins and minerals that help maintain health. Additionally, it is commonly found in cosmetics to enhance nutritional value and fragrance, such as in shampoos, masks, and body lotions.

Malt Extract Production Process

The production process for malt extract generally includes the following steps:

  1. Raw Material Preparation: Choose high-quality barley seeds as raw material, and clean, screen, and soak them to ensure quality and purity.
  2. Germination: Soaked barley seeds are sprouted, usually in a temperature-controlled environment to promote the generation and activation of amylase. Germination typically lasts from 2 to 4 days, during which proper humidity and ventilation must be maintained.
  3. Drying and Crushing: The sprouted barley is dried using drying equipment to reduce moisture content to acceptable levels. It is then crushed or milled into a powder.
  4. Fermentation Process: The crushed barley powder undergoes fermentation, supplemented with water and a fermenting agent to convert starch into sugars and other beneficial compounds. The fermentation time and temperature are controlled according to process requirements.
  5. Extraction: The fermented barley powder is then subjected to extraction, using water or other solvents to extract the desired components into the liquid phase.
  6. Concentration and Separation: The extract is concentrated to remove excess water, resulting in a concentrate. Following this, centrifugation, filtration, and other process steps are performed to isolate pure malt extract.
  7. Drying and Milling: The malt extract undergoes another drying process to meet water content standards, followed by milling to achieve the desired powder form.
  8. Packaging and Storage: The malt extract product is packaged, typically using moisture-proof and light-proof materials to ensure quality. It should be stored in a dry, cool place to avoid direct sunlight and high temperatures, extending its shelf life and stability.

Malt Extract Source Plant Introduction, Distribution, and Growing Environment

The source plant for malt extract is barley (scientific name: Hordeum vulgare), an important cereal crop belonging to the Poaceae family.

Plant Introduction:

Barley is an annual herbaceous plant with an upright stem, typically 50 to 120 cm high, and a well-developed root system. Its leaves are linear with sheaths, appearing green and featuring longitudinal stripes on the surface. Male and female spikes grow separately on the same plant, with the flowering period generally occurring from spring to early summer. The fruit is a small caryopsis, commonly known as barley grain, oval or nearly spherical, usually yellow or golden yellow.

Distribution:

Barley is native to the Middle East and later spread to Europe, North Africa, and other parts of Asia. Today, barley is widely cultivated worldwide, primarily concentrated in temperate and cold regions. In China, barley is mainly found in the northeast, northwest, and northern regions.

Growing Environment:

  1. Climate Requirements: Barley is highly adaptable, thriving in mild climates with optimal temperatures between 10°C and 25°C. It has strong resilience to cold, drought, and humid environments.
  2. Soil Requirements: It shows strong soil adaptability but prefers loose, well-drained, and fertile soils, ideally with a pH between 5.5 and 8.0.
  3. Light Requirements: Barley prefers well-lit environments and has a high demand for sunlight.

Cultivation Techniques:

  1. Sowing: Barley is typically sown in the autumn, selecting fertile and well-drained fields. The sowing methods include broadcasting and mechanical sowing, with a general sowing depth of 3 to 5 cm.
  2. Management: During growth, timely weeding, soil loosening, and fertilization are essential to maintain soil moisture, aiding barley development.
  3. Harvesting: Barley generally matures toward the end of the growing season, with harvesting occurring when most spikes turn yellow, and grains are golden, usually during dry weather after spikes have matured.

Since barley is a common crop, its extract is readily available in the market and serves numerous industries with a breadth of applications.

Malt Extract Processing and Storage

The processing of malt extract typically includes the following steps: First, the malt is ground into a powder, and then an appropriate solvent is used for extraction, commonly water or ethanol. During extraction, parameters like temperature, time, and pressure must be controlled to ensure optimal extraction. Following filtration, concentration, and drying, the final malt extract product is obtained.

For storage, malt extract should be kept in a dry, cool, and ventilated environment, avoiding direct sunlight and high temperatures. It is essential to prevent moisture and contamination by storing it in a sealed container and regularly checking its shelf life. Under proper storage conditions, malt extract can maintain good quality and stability.
