The liquid byproduct obtained during potato starch extraction represents a biochemically complex secondary product of significant value. Its composition includes mineral constituents at approximately 1% concentration, organic compounds comprising roughly 4% by volume, and protein fractions accounting for about 2% [1]. Additionally, it contains a vitamin complex (including thiamine, riboflavin, pyridoxine, niacin, ascorbic acid, and tocopherol) alongside anticoagulant compounds such as phytic acid. Notably, the mineral profile of this extract closely mirrors that of the potato tuber itself, excluding the starch and dietary fiber fractions. Estimates suggest that processing one metric ton of starch-bearing raw material can yield up to 3.5 metric tons of this liquid concentrate. Systematic research into its functional properties and safety profile only began in earnest during the final two decades of the 20th century and the early 21st century, thereby unlocking new potential for its application across diverse industrial sectors.

Freshly extracted juice from potato tubers has long been valued in European traditional medicine for its capacity to counteract excessive gastric acidity and alleviate smooth muscle spasms within the gastrointestinal tract, thereby serving as a time-honored remedy for digestive disorders [2]. Its biochemical profile includes specialized protein constituents—namely patatins, which function as storage proteins, alongside protease inhibitors that exert beneficial physiological effects. These compounds are hypothesized to underlie the juice’s observed anti-inflammatory properties. Additionally, the juice contains glycoalkaloids such as solanine and α-chaconine, substances historically classified as toxic to humans. Nevertheless, emerging scientific evidence suggests that when administered in controlled quantities, these compounds may exhibit antitumor activity and modulate inflammatory immune responses [1, 3]. Given this multifaceted pharmacological potential, researchers have proposed investigating potato juice as a functional food ingredient for individuals diagnosed with inflammatory bowel disease (IBD) [4]. A preliminary clinical trial involving 44 participants with diverse dyspeptic symptoms evaluated the efficacy and tolerability of consuming 100 milliliters or more of the juice twice daily over a one-week period. Approximately 66% of the subjects reported significant improvements in symptoms and overall well-being, thereby warranting further large-scale investigations [5]. It is critical to emphasize, however, that consumption should be strictly moderated—the maximum safe dosage corresponds to the volume obtainable from a single tuber, as exceeding this threshold may induce toxicological effects in the body.

Emerging scientific evidence suggests that freshly extracted juice from raw potato tubers, when consumed in measured quantities, may exert a beneficial effect on the healing process of ulcerative lesions within the gastrointestinal tract while simultaneously alleviating associated pain symptoms. Furthermore, in traditional folk medicine practices, unprocessed potato juice has been employed as an adjunct remedy for gastric dysfunction and edematous conditions arising from excessive fluid retention. Clinical recommendations in such instances propose the ingestion of approximately 120 milliliters (equivalent to half a standard cup) of this beverage, administered up to four times daily over a span of several months—particularly as a complementary approach to conventional duodenal ulcer treatment protocols, as referenced in select specialized literature [6].

Freshly extracted juice from potato tubers serves as a concentrated source of B-complex vitamins (including thiamine, riboflavin, and niacin), fat-soluble vitamin E with potent antioxidant capacity, and ascorbic acid (vitamin C), all of which collectively contribute to enhanced hair follicle health, accelerated growth cycles, and reduced shedding. When incorporated into a consistent hair care regimen—whether as a standalone scalp treatment or blended with complementary active ingredients such as raw honey, aloe vera gel, or egg white protein—this botanical extract may facilitate the repair of damaged cuticles, stimulate dormant follicles, and mitigate excessive hair loss. Preparation involves blending peeled potatoes and straining the liquid through cheesecloth or utilizing a cold-press juicer to preserve enzymatic activity. The resulting juice is applied to cleansed scalp skin using gentle circular motions for 3–5 minutes, then allowed to penetrate for 15–20 minutes prior to rinsing with tepid water. Notably, the biochemical profile of potato juice closely mirrors that of the tuber itself—excluding dietary fiber and starch components—while retaining essential minerals like potassium, magnesium, and phosphorus. While emerging research primarily explores its potential gastroprotective effects (e.g., alleviating dyspeptic symptoms or gastric mucosal inflammation), oral consumption should be moderated due to documented toxicological risks associated with excessive intake.
