Juice can be frozen for longer storage, but you'll find that any remaining solid bits fall out of suspension and sink to the bottom after defrosting. I'm not personally a huge fan of the texture of defrosted juice, but if you're okay with it, freezing can be a good bet. Arbutin, hydroquinone-β- d-glucopyranoside (Fig. 2), is a well-known antibiotic [ 22], and skin whitening compound [ 23, 24]. It is degraded into hydroquinone, a skin bleaching agent, and is used in cosmetics as a fragrance, reducing agent, and melanin polymerization inhibitor. Hydroquinone mediates immune function in vitro and in vivo, however, these effects have not yet been established in humans [ 24, 25]. A Chinese group reported the peel of imported Korean pears (Chinese name, Youran) contained approx. 1.5–20 fold higher amounts of arbutin (6982.0 μg/g dry weight) than other 9 different pear varieties cultivated (323.3–4395.8 μg/g dry weight) in China and South Africa [ 9]. In Oriental pears, the greatest concentration of arbutin was found in the peel (1.20 mg/g fresh weight), which was 3–5 times greater than that found in the core and 10–45 times greater than the level in the pulp [ 26, 27]. Therefore, pear skins, especially those of Korean pears, are one of the richest food sources of natural arbutin [ 28]. As such, arbutin can serve as a potential pear-specific intake biomarker [ 29].

Pear juice is a healthy beverage that is also a great way to use up extra pears before they go bad. Sanchez ACG, Gil-Izquierdo A, Gil MI.

Fresh juice is best served right after it’s made. But, it can be stored in a covered container in the refrigerator for up to 4 days. Veberic R, Slatnar A, Bizjak J, Stampar F, Mikulic-Petkovsek M.

If your juicer has multiple speeds, use a slower speed for softer ingredients like leafy greens, soft herbs, and citrus. Secondly, pears can be anti-carcinogenic by virtue of their nitrite scavenging activity [ 79, 80]. As nitrites are widely used during food processing and storage, they may easily react with amines to produce strong carcinogens, such as N-nitrosamines, in the processed food. The nitrite scavenging activity of Asian pears, such as Baekwoon and Niitaka, was 80.7–86.7% [ 79, 80]. These pears showed comparably high nitrite scavenging activity than other plants, such as onions (50%) or kiwis (75.3–81.8%) [ 12]. Yan C, Yin M, Zhang N, Jin Q, Fang Z, Lin Y, et al.

Skip the canned or boxed juice drinks and make your own! I’ll show you how to do it in a juicer or a blender. You should lay the pear on its side and make 4 – 6 vertical cuts around the core to get all the flesh from the core. The flesh then can be chopped down into a size that fits your juicer’s feed chute. Regardless of variety, choose pears that are very firm, with no give at all. If choosing a russet variety, it should be a deep golden-brown. Smooth-skinned round fruits should be more yellow than green. Smooth-skinned pear shaped fruits should be pale green. How to storeLee H, Isse T, Kawamoto T, Woo H, Kim AK, Park JY, et al.

Pears are great sources of antioxidants and vitamins such as A, B1, B2, and K. These vitamins are essential for immune function as they stimulate white cell production and activity. The antioxidants in pears fight free radicals and decrease your risk of diseases. 3. Improve Heart Health Nieman D, Gillitt N, Sha W, Meaney M, John C, Pappan K, et al.

Pear juice can aid you in achieving flawless, glowing skin. A high capacity of vitamins, minerals, antioxidants, and phytonutrients from this drink will nourish your skin. Plus, antioxidants protect skin from oxidative damage, keeping it smooth and soft. Azuma et al. evaluated the suppressive and anti-inflammatory effects of cellulose nanofibers from Japanese pears ( P. pyrifolia, Nijuseiki) on inflammatory bowel disease (IBD): The pear nanofiber demonstrated anti-inflammatory effects via suppression of fibroses or by butyrate-mediated inhibition of NF-κB in an IBD murine model [ 86].
