Ultrasound pretreatment and solvent extraction parameters effects on the nutritional characteristics of Indonesian shortfin eel () protein concentrate.

Protein concentrate (PC) is a potential solution to address the global protein shortage, with Indonesian shortfin eel being a suitable raw material. This research investigates the impact of ultrasound pretreatment and extraction parameters on the nutritional quality of eel protein concentrate (EPC). The study involved ultrasonic pretreatment at different times and power, and solvent extraction with different solvents, temperature, and solvent-solid-feed-ratio (SSFR).

Effects of drying temperature and relative humidity on the quality of dried onion slice.

Onion, a very common season ingredient, is useful as an antioxidant and optimal conditions are required for its drying while ensuring the best quality is retained. This study evaluated the effect of drying temperatures and relative humidity on both drying rate and onion quality. Onions with an average diameter of 20.

Effect of drying and milling modes on the quality of white rice of an Indonesian long grain rice cultivar.

Background: Many studies have revealed the susceptibility of long grain rice to breaking during milling, while others have demonstrated the variation in the yield of head rice due to different rough rice drying methods. Thus, this study aims to determine appropriate drying and milling methods to improve the head rice yield and nutritional quality of long grain rice.

Methods: A series of drying experiments were performed on rough paddy rice employing shallow bed, oven and sun drying methods.

Drying Rate and Product Quality Evaluation of Roselle ( L.) Calyces Extract Dried with Foaming Agent under Different Temperatures.

The utilisation of roselle ( L.) calyx as a source of anthocyanins has been explored through intensive investigations. Due to its perishable property, the transformation of roselle calyces into dried extract without reducing their quality is highly challenging.
