Effects of Multiple Freeze-Thaw Cycles on Biochemical and Physical Quality Changes of White Shrimp (Penaeus vannamei) Treated with Lysine and Sodium Bicarbonate.

Freezing and thawing occur during storage, transportation, and retail display, leading to deterioration of frozen shrimp. The objective of this research was to investigate the change in quality of frozen white shrimp treated by lysine and NaHCO after multiple freeze-thaw cycles. Shrimp were soaked in lysine and lysine/NaHCO each at 1% (w/v) frozen in an air-blast freezer at -30 °C, and kept in a chest freezer (-18 ± 2 °C) for a week before they were thawed using tap water before the analysis (freeze-thaw cycle 1).

Physicochemical Properties of Defatted Rambutan (Nephelium lappaceum) Seed Flour after Alkaline Treatment.

Rambutan seeds were subjected to SC-CO₂ extraction at 35 MPa, 45 °C to obtain defatted rambutan seed flour. Its physicochemical properties before and after treatment with alkali solution using 0.075 N NaOH were investigated.

Expansion and functional properties of extruded snacks enriched with nutrition sources from food processing by-products.

Rich sources of protein and dietary fiber from food processing by-products, defatted soybean meal, germinated brown rice meal, and mango peel fiber, were added to corn grit at 20 % (w/w) to produce fortified extruded snacks. Increase of total dietary fiber from 4.82 % (wb) to 5.

Characteristics and antioxidant of Ulva intestinalis sulphated polysaccharides extracted with different solvents.

Ulva intestinalis, a tubular green seaweed, is a rich source of nutrient, especially sulphated polysaccharides. Sulphated polysaccharides from U. intestinalis were extracted with distilled water, 0.
