Abstract Previous studies have shown that each edible oil type has its own characteristic fatty acid profile; however, no method has yet been described allowing the identification of oil types simply based on this characteristic. Moreover, the fatty acid profile of a specific oil type can be mimicked by a mixture of 2 or more oil types. This has led to fraudulent oil adulteration and intentional mislabeling of edible oils threatening food safety and endangering public health. Here, we present a machine learning method to uncover fatty acid patterns discriminative for ten different plant oil types and their intra-variability. We also describe a supervised end-to-end learning method that can be generalized to oil composition of any given mixtures. Trained on a large number of simulated oil mixtures, independent test dataset validation demonstrates that the model has a 50th percentile absolute error between 1.4–1.8% and a 90th percentile error of 4–5.4% for any 3-way mixtures of the ten oil types. The deep learning model can also be further refined with on-line training. Because oil-producing plants have diverse geographical origins and hence slightly varying fatty acid profiles, an online-training method provides also a way to capture useful knowledge presently unavailable. Our method allows the ability to control product quality, determining the fair price of purchased oils and in-turn allowing health-conscious consumers the future of accurate labeling.

The present study reports obtaining biofuel by pyrolysis of plant oil and animal fat. This process consists in breaking of molecules at high temperatures, obtaining hydrocarbons, similar to oil, and oxygenates such as esters, carboxylic acids, aldehydes, etc. The research aimed to evaluate the thermal and kinetic behaviour and the heat of combustion of bio-oil and bio-oil mixtures / diesel oil. In this work, Thermogravimetric studies were performed (TG) at a heating rate of 10 ° C min-1 under air atmosphere synthetic, Thermodynamic studies (ΔH, ΔS and ΔG) and about heat of combustion also were done. Thermal stability at 30°C was observed from thermogravimetric study. The kinetic calculations were performed in order to observe parameters such as activation energy (Ea) and Arrhenius factor.

Results:Clinicaldry score, pruritus severity of plants oil mixtures group were significantly decreasedthan VCO at week 2 and 4 (p 0.000). Skin hydration and sebum level of plants oilmixture group were significantly increased than VCO at week 2 and 4 (p0.000).Clinical dry score, pruritus severity, skin hydration, andskin sebum levels ofplant oil mixtures were significantly better than VCO at week 4 (p 0.000). There isno side effects on both of plant oil mixtures and VCO groups Conclusion: Plant oilmixtures add pureCelin oil showed better efficacy as a therapeutin and maintanancemoisturizer for xerosis and pruritus in elderly. Both of plant oil mixtures and VCOcan be tolerated and safe to use.

Poor Efficacy

Oxytetracycline (OTC) has been commonly used as an effective antibiotic against various fish bacterial diseases, including vibriosis. In this study, the absorption-enhancing effect of citric acid on oral OTC pharmacokinetics and treatment of artificial Vibrio anguillarum infection was evaluated in juvenile yellowtail Seriola quinqueradiata followed by serum OTC concentration analysis. When 25 mg kg-1 body weight (BW) OTC was administered in combination with 1250 mg kg-1 BW citric acid, the serum OTC concentration reached almost the same concentration as that of the group treated with 50 mg kg-1 BW OTC. This coadministration successfully suppressed mortality due to vibriosis similar to the group treated with 50 mg kg-1 BW OTC. Conversely, poor efficacy was observed when only 25 mg kg-1 BW OTC was administered. These results suggest that coadministration of citric acid can be beneficial in reducing the dose of OTC needed for effective treatment, and thus contributes to the goal of reduced use of this antibiotic in aquaculture.

Asam lemak bebas (alb) dalam Crude Palm Oil (CPO) merupakan salah satu parameter kualitas CPO.Munculnya asamlemak bebas ini dapat berasal dari faktor pemanenan dan penyimpanan. Asamlemak bebas yang tinggi dalam CPO dapat menurunkan harga CPO. Minyak mentah sawit inimerupakan salah satu sumber energi terbarukan yang diolah, antara lain, menjadi pure plant oil (PPO)dan biodiesel. Namun,masalah utama CPO sebagai bahan baku PPO dan biodiesel adalah asamlemak bebas. Asam lemak bebas dalam CPO yang dapat digunakan untuk PPO dan biodiesel tidakboleh lebih dari 1%. Oleh karena itu, dalam penelitian ini dilakukan usaha untuk menurunkan asamlemak bebas dalam CPO sehingga dapat dimanfaatkan sebagai bahan bakar. Metoda yang digunakanadalah esterifikasi. Asam lemak bebas dikonversi menjadi metil ester. Campuran metil ester dengantrigliserida ini merupakan bahan bakar yang dapat digunakan untuk pengganti BBM. Kondisi yangoptimal untuk proses esterifikasi CPO alb tinggi adalah sebagai berikut : suhu 65oC, waktu 360 menit,katalis 0,25%, dan perbandingan mol metanol 8:1. Dengan proses ini, asam lemak bebas dapatditurunkan menjadi 2,76% (konversi 89,39%). Pada kondisi yang sama dengan katalis yangditingkatkan menjadi 0,5%, asam lemak bebas dapat diturunkan menjadi 1,86% (konversi 92,85%).Pada kondisi yang sama, dengan katalis yang ditingkatkan menjadi 1%, asam lemak bebas dapatditurunkan menjadi 1,75% (konversi 93,28%).Kata kunci: asam lemak bebas, CPO, esterifikasi, PPO, biodiesel
