Tomato seed meal

Presscakes for cattle feed. The high protein and fiber content (33% and 25%, respectively) should make the presscake useable for ruminant feed. Tomato seed meal contains about 10% moisture, 47% protein, 32% crude fiber and 15% other carbohydrates with an ash content of 5% which is rich in magnesium, calcium, potassium, and also contains sodium, phosphorus and iron. 

Edible protein. The protein fraction of tomato seed is about 35% of the dry weight. This is higher than that of cottonseed which is about 20% protein (Morad et al., 1980). Three cultivars of tomato examined for amino acid composition had higher levels of lysine compared to commercial soybean meal (Rymal et al., 1974). Soymeal was higher in threonine, serine and histidine than tomato meal while both meals were low in methionine. Blended with low lysine protein sources, the tomato meal may be useful for balancing essential amino acids. The protein comprised about 33% of the seed (Bertoni et al., 1963). The limiting amino acids in tomato seed are methionine and cystine.

Information on the occurrence of alternaria mycotoxins in food and feed is relatively limited. For example altemariol, its methyl ether and tenuazonic acid were frequently detected in apples, apple products, apple juice concentrates, mandarins, ohves, pepper, red pepper, tomatoes, tomato products, oilseed rape meal, sunflower seeds, sorghum, wheat and edible oils (olive oil, rapeseed oil, sesame oil and sunflower oil). The maximum levels reported in foods are...
