For the walnut kernels
LIGHT QUARTERS YUNNAN FAT TYPE
1. Full granules and thick meat texture
Yunnan fat type walnut kernels are known for their "fat" quality, with large and plump kernels, thick flesh, high kernel yield (usually up to 50% or more), and a delicate and oily taste.
2. Natural color and excellent appearance
Renyi (seed coat) is light yellow to amber in color. After peeling, the inner kernel is milky white or light yellow, with a uniform color and few black spots or mold. The appearance is clean and beautiful.
3. Rich in nutrients
Rich in unsaturated fatty acids (especially linoleic acid and alpha linolenic acid), protein (about 15-20%), vitamin E, and minerals such as calcium, phosphorus, and iron, the nutritional value is higher than that of ordinary walnut varieties.
4. Unique flavor
When eaten raw, it has a light and slightly sweet fragrance, and after baking, it is crispy and fragrant. The oil content is moderate (about 60-65%), and the aftertaste is mellow without astringency, with little greasy feeling.
5. Low moisture content, storage resistance
The dry climate of the Yunnan Plateau results in low moisture content (usually<8%) in walnut kernels, making them less prone to spoilage and having a longer shelf life.
6. Green ecological attributes
Most of the production areas in Yunnan have high altitudes (1500-2500 meters), sufficient sunshine, and low pollution. Walnut cultivation mostly adopts traditional methods with low pesticide residues, which meets the standards of green food.
7. Processing advantages
Due to the high integrity of the kernel, it is suitable for deep processing (such as amber walnuts, walnut oil, etc.), with low kernel crushing rate and high commodity rate.
matters needing attention:
It is necessary to distinguish between "fat type" and ordinary walnut kernels. Some merchants may mix them. It is recommended to choose reputable brands or products directly supplied from the place of origin.
Moisture and light should be avoided during storage to maintain flavor and prevent oil oxidation.
Yunnan fat walnut kernels are particularly suitable for high-end snacks, health product raw materials, and exports, and are one of the representatives of Yunnan plateau characteristic agricultural products.
EXTRA LIGHT HALVES YUNNAN THIN TYPE WALNUT KERNELS
1. Long and slender appearance, compact and sturdy body
The kernels are slender, pointed and thin in shape, with small particles, but the kernels are compact and have high integrity, making them suitable for processing products with shape requirements (such as high-end snack blends).
2. Pure white color and appearance
Renyi (seed coat) is relatively thin, appearing light yellow or light white, with the inner kernel as white as jade, less impurities, and a clean and refreshing appearance. It is suitable for food processing with strict color requirements (such as pastry decoration and cold meal pairing).
3. Moderate oil content, refreshing flavor
Compared to fat walnut kernels, the pointed white lean type has slightly lower oil content (about 55-60%), a fresher taste, obvious sweetness, and extremely light astringency, making it suitable for consumers who prefer a light taste.
4. High protein content and balanced nutrition
Due to its compact body and relatively high protein content (about 18-22%), it is also rich in dietary fiber, making it suitable for fitness enthusiasts or those who require a low-fat diet.
5. Resistant to storage and not easily oxidized
Due to its low oil content and dry climate on the Yunnan Plateau, there is a lower risk of oxidation and deterioration during storage, resulting in a longer shelf life.
6. Strong processing applicability
Suitable for whole grain use (such as chocolate wrap, candied walnuts), with low kernel breakage rate, and can also be used to make deep processed products such as walnut powder and protein drinks.
7. Green planting, controllable quality
The pointed white lean walnuts in high-altitude production areas in Yunnan, such as Dali and Lincang, are mostly grown ecologically with low pesticide residues and meet organic food standards.
Market positioning and usage
High end food ingredients: such as pastry decoration, healthy snacks, salad toppers.
Health consumption: Suitable for people who pay attention to low-fat and high protein diet.
Export demand: Due to its neat appearance and good color, it is highly favored by the Japanese, Korean, and Southeast Asian markets.
precautions
It needs to be distinguished from fat walnut kernels to avoid confusion in pricing.
Moisture proofing is still necessary during storage to maintain brittleness and whiteness.
Yunnan Jianbai lean walnut kernels have become a distinctive product in the segmented market due to their refreshing taste and high appearance, especially suitable for consumption scenarios with high requirements for food appearance and health attributes.
185TYPE XINJIANG ORIGIN WALNUT KERNELS LIGHT QUARTERS,LIGHT BROKENS,LIGHT SMALL BROKENS,LIGHT AMBER HALVES,LIGHT AMBER QUARTERS,LIGHT AMBER BROKENS,LIGHT AMBER SMALL BROKENS
1. Ultra thin shell with extremely high kernel yield
The shell thickness is only 0.8-1.2 millimeters, and it can be opened by hand. The kernel yield is as high as 60% -70% (about 50% for ordinary walnuts), and the whole kernel rate exceeds 90%, with low processing costs.
Significant advantages: Convenient household consumption and high processing efficiency in food factories.
2. The kernel is plump and full, with a golden and translucent white color
The kernels are plump and thick, with a light golden yellow kernel coat (seed coat) and a milky white and slightly yellow inner kernel. The color is uniform and bright, without black spots or mold.
Appearance grade: High proportion of special grade kernels, suitable for the high-end market.
3. Rich in oil, with a crispy and sweet taste
Oil content of 68% -72% (one of the highest in China), crispy and flaky on the palate, prominent sweetness, almost no astringency, and a milky aftertaste.
4. High nutrient density and outstanding health value
Unsaturated fatty acids account for ≥ 90% (with high levels of linoleic acid and alpha linolenic acid), protein content ranges from 16% to 18%, and are rich in trace elements such as vitamin E, zinc, and selenium.
Core selling point: significant cardiovascular health care and brain strengthening effects.
5. Low moisture content, resistant to storage and transportation
The arid climate in Xinjiang causes walnut kernels to have a moisture content of ≤ 6%, making them less prone to mold growth. They can be stored at room temperature and sealed for more than 12 months (protected from light and oxidation).
6. Natural growth, safe and additive free
The southern foothills of the Tianshan Mountains in Xinjiang (production areas such as Wensu and Aksu) have long sunshine hours (over 2800 hours per year), large temperature differences between day and night, no need for pesticides, and are naturally green.
Market positioning and usage
High end snacks: original raw food, amber walnuts, walnut chocolate.
Deep processing: cold pressed walnut oil (oil yield ≥ 50%), protein powder, health products.
Export flagship: the preferred variety for high-end markets in the EU, Middle East, Japan, and South Korea.
