Can grapes be juiced directly

Grapes can be juiced directly, but it is important to clean them thoroughly and remove the stems. Grape juice extraction can preserve anthocyanins and dietary fiber in the skin, but some varieties of seeds may affect the taste.

Grape skins may contain residual pesticides or dust. It is recommended to rinse them repeatedly with running water and gently rub the surface with a small amount of edible salt if necessary. The fruit stem contains tannic acid, and direct juice extraction can easily lead to a bitter taste, which needs to be removed in advance. The skin of purple grapes is rich in antioxidants, and juicing the skin can enhance its nutritional value, but it is important to ensure that the fruit is fresh and free from decay. Some hard seeded varieties such as Kyoho grapes may produce residue after juicing, which can be filtered and consumed or seedless grapes are more convenient. People with gastrointestinal sensitivity should control their consumption of grape juice, as fruit acids may irritate the gastric mucosa. Patients with diabetes need to pay attention to the high sugar content of grapes, which is easier to absorb after juice extraction. It is recommended to squeeze and drink homemade grape juice immediately to avoid the oxidation and loss of vitamin C. Mixing carrots or apples for juice extraction can balance acidity and sweetness and increase the variety of nutrients. The wall breaking machine can retain more dietary fiber, but high-speed stirring may cause some nutrients to be damaged by heat. Grape juice is suitable as an electrolyte supplement drink after exercise, and potassium helps alleviate muscle fatigue. In summer, ice cubes can be added to make cold drinks, and in winter, heating and drinking should be controlled to avoid damaging the active ingredients. Daily consumption should not exceed 300 milliliters, and it is recommended to consume nuts to slow down blood sugar rise. Children should dilute and reduce the sugar concentration when drinking, while the elderly should drink slowly in small sips to avoid coughing. If there is bloating or diarrhea, it is necessary to stop drinking and consult a nutritionist to adjust the diet plan if necessary.
