A comparative study of the properties of 10 variety melon seeds and seed oils

Abstract

The moisture content of seeds of the melon varieties varied between 4.8%–6.3%, the ash interval 2.5%–3.5%, the crude oil 19.4%–33.0%, the crude protein 30.4%–37.2%, and the crude cellulose value 1.5%–2.7%. Flavonoid contents of seeds were found between 134 and 257 mg CE/kg, and the total phenol contents were found between 615 and 850 mg GAE/kg. The phosphorus contents of melon seeds changed between 5,912 and 8,964 mg/kg. The seed oils contained 57.1%–74.7% linoleic, 13.0%–28.4% oleic, and 7.0%–10.1% palmitic acids. While α‐tocopherol contents of oils varied between 1.8 mg/kg (Kırkağaç‐Dalaman) and 10.4 mg/100 g (Çankırı winter), γ‐tocopherol contents of oils changed between 6.6 mg/100 g (Mühürlü) and 30.0 mg/100 g (Çankırı winter). The cholesterol, brassicasterol, campesterol, stigmasterol, sitosterol, and sitostanol contents were the main sterols for Chocolate variety oil (13.73, 14.21, 27.41, 38.05, 152.04, and 117.57 mg/kg, respectively).The ∆5‐avenasterol (116.62 mg/kg) and ∆7‐avenasterol (31.28 mg/kg) were significantly (p < .05) high in Çankırı winter. ∆7‐stigmastenol content was dominated in Kırkağaç‐Dalaman seed oil (143.69 mg/kg). Practical applications Seeds belonging to Cucurbitaceae family are known to be as rich in oil. The fatty acid profile plays an important role in their stabiliy and nutritional value. The high content oil showing useful characteristics such as odorlessness, good color. Melon seed oil rich in the bioactive components. These seeds suitable for oil industrial applications. Because many of these oils were used as cooking oil in some countries in Africa and in the Middle East, the melon seed oils could be developed into the commercial products to serve as alternate vegetable oils.

Quality and Antioxidant Properties of Cold-Pressed Oil from Blanched and Microwave-Pretreated Pomegranate Seed

“…The absorbance was measured at 460 nm using a UV spectrophotometer (Spectrum Instruments, United Scientific, Cape Town, South Africa), and the results were expressed as mgβ-carotene/g of PSO. The Folin–Ciocalteu method was applied to evaluate the total phenolic content (TPC) [ 28 ]. Briefly, 200 µL of PSO methanol extracts, 250 µL of the Folin–Ciocalteau reagent, 750 µL of 2% ( w/v ) sodium carbonate, and 3 mL of distilled water were sequentially mixed, and the mixtures were vortexed and incubated in the dark for 40 min.…”

Valorization of apricot, melon, and watermelon by-products by extracting vegetable oils from their seeds and formulating margarine

“…This oil offers also substantial contents of some SFA such as stearic (5-9%) acid (Silva et al, 2019). The contents of these acids are in the range revealed by Kale et al (2020) when analyzing the seed oils of 10 melon varieties: linoleic (57.1-74.7%), oleic (13.0-28.4%), and palmitic (7.0-10.1%) acids. Whereas, the amounts of the major SFA (palmitic acid, stearic acid, and butyric acid) in MSO varied from 1.09 to 11.9%, and the quantity of oleic acid was between 55.1 and 55.7% (Chen et al, 2021).…”

Cytogenetic Toxicity and Infertile Properties of the Aqueous Extract of Cucumis melo Seeds (Cucurbitaceae) in Male Zonocerus variegatus Cell Model (Orthoptera: Pyrgomorphidae)

“…Moreover, extracts of C. melo have shown antioxidant [9,10], anti-ulcer [11], anticancer [12,13], antidiabetic [14], antimicrobials and anthelmintics [15,16] properties. Ethnomedicine also reports that the seeds and their oils can be used against dysuria and gout or as purgatives and dewormers [1,11,17]. The seeds are consumed mainly in the form of pistachio dish.…”
