How to remove walnut kernels from leather clothing

The main methods for peeling walnut kernels include hot water soaking, oven baking, freezing, manual peeling, and microwave heating.

1. Hot water soaking method

Soak walnut kernels in hot water for about 10 minutes, with the water temperature controlled at 60-70 degrees Celsius. Hot water can soften the skin on the surface of walnut kernels, and after soaking, the skin will naturally expand and separate from the kernels. At this point, gently rub the walnut kernels with both hands, and the leather jacket can easily fall off. This method is easy to operate and can maximize the retention of the nutritional components of walnut kernels, making it suitable for daily household use.

2. Oven baking method

Lay the walnut kernels flat on a baking tray and bake them in a preheated oven at 150 degrees Celsius for 5-8 minutes. High temperatures can cause leather jackets to shrink and crack. After taking them out, gently rub them to remove them. The baking time should not be too long, otherwise it will cause walnut kernel oil to seep out and affect the taste. This method has high peeling efficiency and is suitable for situations where a large amount of walnut kernels need to be processed.

3. Freezing method

Put walnut kernels into sealed bags and freeze them in the freezer compartment of the refrigerator for more than 2 hours. Low temperature can cause separation between the leather jacket and the nuts due to different shrinkage rates. After removal, gently tap or rub to remove the skin. Freezing method can maintain the original flavor of walnut kernels, but it requires a longer processing time and is suitable for situations where they are not in a hurry to use.

4. Manual Peeling Method

Pinch the ends of the walnut kernels with your thumb and index finger, gently pry them apart along the longitudinal direction, and then use your nails or knife to scrape off any remaining skin. Although this method is time-consuming and laborious, it can accurately control the degree of peeling, making it suitable for situations where high integrity requirements are placed on walnut kernels. Control the force during operation to avoid damaging the nuts.

5. Microwave heating method

Spread walnut kernels flat in a microwave oven container and heat on medium high heat for 30 seconds to 1 minute. Microwaves can quickly evaporate the moisture inside the leather jacket, causing it to expand and naturally curl up when removed. This method is fast but requires close observation to prevent excessive heating from causing walnut kernels to harden. The processing capacity should not be too much each time to ensure even heating.

After peeling walnut kernels, it is recommended to consume them as soon as possible or store them in a sealed container to avoid oxidation and spoilage. During the peeling process, suitable methods can be selected according to actual needs. Hot water soaking and oven baking are suitable for most household scenarios. Walnut kernels are rich in unsaturated fatty acids, vitamin E, and various minerals. Moderate consumption can help promote cardiovascular and cerebrovascular health, but the recommended daily intake is 20-30 grams. For people with weaker digestive function, peeled walnut kernels are easier to digest and absorb. When storing, pay attention to moisture and insect prevention. It can be placed in a sealed container and stored in a cool place.
