Kalsium merupakan mineral esensial yang memiliki peranan penting di dalam tubuh untuk pembentukan tulang. umumnya dikonsumsi bentuk mikro kalsium menyebabkan penyerapan oleh hanya 50% sehingga sering defisiensi. Sumber aman digunakan dari tulang ikan, limbah tidak termanfaatkan, salah satunya adalah ikan tenggiri. Pada penelitian ini ultrasound-assisted extraction (UAE) mengekstrak nanokalsium....

An analytical ultrasound-assisted extraction (UAE) method has been optimized and validated for the rapid extraction of stilbenes from grape canes. The influence of sample pre-treatment (oven or freeze-drying) and several extraction variables (solvent, sample-solvent ratio and extraction time between others) on the extraction process were analyzed. The new method allowed the main stilbenes in gr...

In this work, an environmentally friendly sample pre-treatment method, Ultrasound Assisted Surfactant Enhanced Emulsification Microextraction (UASEME) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. After the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfac...

This study aimed to recover β-carotene from peels produced as a by-product during the industrial processing of pumpkins using high-efficiency technology that produces no waste and is harmless environment. β-Carotene extraction pumpkin peel was carried out by maceration ultrasound-assisted technique, with sunflower oil instead n-hexane an environment-friendly solvent. Influence lecithin:PGPR (po...

In this study, ultrasound- and enzyme-assisted extractions of albumin (water-soluble protein group) from defatted pumpkin (Cucurbita pepo) seed powder were compared. Both advanced extraction techniques strongly increased the albumin yield in comparison with conventional extraction. The extraction rate was two times faster in the ultrasonic extraction than in the enzymatic extraction. However, t...

In this study the phenolic compounds piceid, resveratrol and emodin were extracted from P. cuspidatum roots using ultrasound-assisted extraction. Multiple response surface methodology was used to optimize the extraction conditions of these phenolic compounds. A three-factor and three-level Box-Behnken experimental design was employed to evaluate the effects of the operation parameters, includin...

Bioactive ingredients can be extracted from surplus soft fruits to add value them as a fortification ingredient in many new products. Ultrasound-assisted extraction and spray drying have been heavily studied the past, with evidence suggest positive uptake of these by food industry. In this paper, strawberries, raspberries blackberries were examined using distilled water ‘green’ method assisted ...
