“…Tomato seeds have been shown to contain ca. 20% oil [7] with a fatty acid composition of tomato seed essentially like that of low linolenic soybean oil [8]. It has been suggested that tomato seeds would be a good source of salad oil [9].…”

Tomato seeds represent a very large waste byproduct from the processing of tomatoes into products such as tomato juice, sauce and paste. One potential use for these seeds is as a source of vegetable oil. This research investigated the oil content of tomato seeds using several extraction techniques as well as an examination of the oil extracts to determine the composition of the minor constituents such as phytosterol and antioxidant composition. The oxygen radical absorbance capacity (ORAC) of the tomato seed oils were also measured and correlated with antioxidant contents. This research demonstrated that tomato seed oil yield was highest using hot ethanol and followed by hot hexane and finally SC-CO 2 . The SC-CO 2 treatment, however, had the highest total phytosterol content as well as highest individual phytosterol content. Sitosterol, cycloartanol, and stigmasterol were the most abundant phytosterols present in the extracts. The highest concentrations of antioxidants were found in the hexane extract. The most abundant antioxidants found in the tomato seed oils were all-trans-lycopene, cis-3-lycopene and b-carotene. ORAC was highest for the hexane extract. Oil yield was inversely proportional to both a-tocopherol and c-tocopherol content and positively correlated with cis-3-lycopene content. ORAC values were positively correlated with only all-trans-lycopene and cis-3-lycopene demonstrating their role as antioxidants in the tomato seed oil.

“…The cost should be relatively low. Rabak (1917) reported that there was rather widespread use of dried tomato waste in Italy as a cattle feed. At the 12 to 15 percent feeding level the results were very satisfactory.…”

“…begin (3). Since that time studies were conducted in this country (2,12,15,17,18,20,26,28,30) and in many countries in Europe and South America (5, 6, 7, 8, 9, 10, 11, 13, 14, 21,24,25,27,31) which reported fatty acid composition of tomato seed oil, crude protein and oil content of tomato seeds, and other data related to tomato seed utilization. Most of the work was conducted without benefit of gas chromatography and the results showed considerable variability especially in fatty acid composition of the oil.…”

Fatty acids of the seed oils of ‘Chico Grande’, ‘Rutgers’, and ‘Golden Jubilee’ tomatoes, determined by gas liquid chromatography (GLC), showed no significant quantitative or qualitative differences among cultivars. The major fatty acids were linoleic, 58.0%; oleic, 19.9%; palmitic, 15.6% and stearic, 4.5%. Seven minor acids included linolenic, 1.8%; and trace amounts of myristic, myristoleic, palmitoleic, margaric, arachidic, and a 17 C acid not identified. Sixteen amino acids of the solvent extracted seed meals, determined by ion exchange chromatography, showed significant quantitative differences among the 3 cultivars in glutamic acid, glycine, tyrosine, arginine, and lysine. ‘Golden Jubilee’ seed meal protein contained 10.22% lysine compared to 9.23% for ‘Rutgers’, 9.04% for ‘Chico Grande’ and 7.63% for commercial soybean meal. The tomato seed meals were significantly different from the soybean meal in 10 of 16 amino acids. Soybean meal was higher in threonine, serine, and histidine than any of the tomato seed meals and higher than one of them in leucine and isoleucine. All the tomato seed meals and soybean meal were low in methionine.
