Which Aloe Vera Can Be Eaten
Aloe vera, as a plant that can be used both as medicine and food, has received a lot of attention, but not all varieties are suitable for consumption. This article will systematically introduce you to the identification characteristics, nutritional components, and safe consumption guidelines of edible aloe vera, with detailed illustrations of the morphological features of the four edible varieties.
Characteristics of Edible Aloe Vera Varieties
Standing Aloe
An upright variety native to Japan, with a stem height of up to 1-2 meters. The leaf gel contains aloin and polysaccharides and needs to be peeled and sliced for cold dishes or juicing. Research shows that it contains up to 3.2mg/g of flavonoids, which have antioxidant effects, but the recommended daily intake is no more than 30g.
Curacao Aloe
A variety certified for consumption by the U.S. FDA, with thick and juicy leaves. The gel is transparent and tasteless, and can be cut into pieces to make aloe vera yogurt. Its mucin can promote wound healing and is used in medical dressings. A mature plant can have a single leaf weight of up to 800g, but the epidermis contains emodin, which must be completely removed.
Chinese Aloe
A native domesticated variety in China, with a short stem that is rosette-shaped. The leaf flesh pH is between 5.5-6.0, suitable for making aloe candy. The Ministry of Agriculture's test report shows that it contains up to 15% polysaccharides, but pregnant women should eat with caution. The best time for consumption is mature plants that have been growing for more than two years.
Cape Aloe
A native medicinal variety from South Africa, with a thick cuticle on the leaves, up to 0.3mm. It needs to be boiled at high temperatures to destroy calcium oxalate crystals and can be used in soups or made into aloe tea. Its aloin content can be as high as 28%, excessive consumption may cause diarrhea, and it is recommended to limit the daily intake to 20g.
Safety Precautions for Consuming Aloe Vera
1. Epidermis Treatment: Use a ceramic knife to remove 1-2mm of the epidermis. 2. Mucilage Soaking: Soak in water for 30 minutes to remove residual emodin. 3. Allergy Test: Perform a skin contact test before consuming for the first time. 4. Special Groups: Pregnant women, women during their period, and patients with hypoglycemia are prohibited from using.
It is recommended to choose organically grown edible aloe vera and avoid accidental consumption of ornamental varieties.
