The Evaluation of Dietary Addition of Palm and Coconut Oils in Steaming Tomato (Lycopersicon esculentum) Waste Powder on Digestibility of Crude Fiber and Retention of Lycopene and Nitrogen in Broiler Chickens.

Abstract

Lycopene is a powerful antioxidant present in tomatoes and other vegetables and fruits. Present research was carried out to evaluate lycopene and nitrogen retention and crude fiber (CF) digestibility of steaming tomatoes waste powder which was combined with oil. Tomatoes waste in this experiment were local fresh tomato rejected from tomato field around West Sumatera province, Indonesia. The experimental factors were included the type of oil (palm and coconut oils) and dosage of oils (0.25, 0.5, 0.75, 1, and 1.25 %), and each treatment was replicated three times. The results indicated there was an interaction between the type of oil and dosage of oil on lycopene retention, and CF digestibility, while the type of oil and dosage of oil affected lycopene retention significantly. The dosage of oil also influenced lycopene retention, nitrogen retention, CF digestibility significantly. The addition of coconut oil in steaming tomato waste powder increased lycopene and nitrogen retention, and CF digestibility higher than the addition of palm oil to steaming tomato waste powder in broiler chickens. The lycopene and nitrogen retention, and CF digestibility of steaming tomato waste powder added 0.5% coconut oil was the best level for lycopene and nitrogen retention, and CF digestibility in broiler chickens.

Effects of Processed Tomato (Lycopersicon esculentum) Wastes in the Diet on the Serum Lipid Profile of Laying Hens

“…This is presumably due to differences in the digestibility of commercial lycopene and lycopene derived from PTW. Handayani et al (2019) it was found that the retention of lycopene in tomato waste with adding coconut oil was only around 61.74%. This study showed the same results with the report of Mahata et al (2016) that the administration of 12% tomato flour which had been processed by boiling for 8 minutes could reduce blood serum cholesterol of laying hens.…”

“…In addition, lycopene is hydrophobic and lipophilic so that its absorption in the gastrointestinal tract is influenced by the presence of lipids (Colle et al, 2012;Trujillo and Mc-Clements, 2016). Therefore, according to Handayani et al (2018Handayani et al ( , 2019 the rejected tomatoes were first treated with heat, namely steaming at 98°C for 12 minutes and then adding 0.5% coconut oil. It aims to release lycopene from the tomato skin matrix, change its structure in the form of trans lycopene into the form of cis lycopene and increase the absorption of lycopene in the digestive tract in laying hens.…”

“…Japfa) which were healthy, had no physical defects, weighed 1600-1800 g, and produced 82% at the age of 32 weeks at the beginning of the treatment. The feed ingredients used to prepare the experimental rations were PTW (Handayani, et al, 2019), milled corn, rice bran, commercial concentrate HK 338 from PT. New Hope Indonesia, dolomite flour from CV.…”
