Aqueous and ethanol extracts of oven and freeze-dried Streblus asper leaves were investigated using DPPH assay. The presence of phenolic compounds and flavonoids in the extracts, which were detected by Folin and colorimetric assays, respectively, may be responsible for the antioxidant activities of S. asper. The different drying treatments resulted in significant differences (p < 0.05) in the a...

In prospect of developing an oral dosage form of Infliximab, for treatment of Crohn's disease and rheumatoid arthritis, freeze-drying (vial vs Lyoguard trays) and spray-drying were investigated as production method for stable powders. Dextran and inulin were used in combination with sucrose as stabilizing excipients. The drying processes did not affect Infliximab in these formulations, i.e. bot...

Predation is an important factor in the dynamics of gypsy moth (Lymantria dispar L.) populations, yet predation rates can be difÞcult to estimate accurately in the Þeld. Biased estimates can result from spatial heterogeneity in risk or from artifacts associated with deploying prey. Here we compare predation rates on freeze-dried gypsy moth pupae afÞxed with beeswax to pieces of burlap withpreda...

The aim of this study was to evaluate the method producing shelf-stable snacks based on kiwifruit with objective obtaining an appealing snack good taste, color, and nutritional value. Less valuable kiwifruits for size shape were utilized in order reduce production waste. To obtain snacks, two drying methods used: freeze-drying hot air drying. Physical chemical analyses conducted. Furthermore, a...

Oocytes inseminated by intracytoplasmic sperm injection using fresh ejaculated or freeze-dried rhesus macaque sperm showed similar activation, sperm aster assembly, and male-female pronuclear apposition rates.

The aim of this work was to determine the effect different drying treatments: freeze-drying, room-drying, and oven-drying on grape phenolic composition 'Regent' 'Cabernet Sauvignon' varieties. After drying, samples were grounded, submerged ultrasound-assisted extraction, analyzed with high-performance liquid chromatography (HPLC). This study demonstrated that use methods significantly affects c...

The flavor volatile compounds of dried red cashew flowers, cashew leaf-buds, cashew leaves and licorice roots as well as flavored herb teas were analyzed by gas chromatography-mass spectrophotometry (GC-MS). It was found that terpenes, including α-pinene, α-phellandrene and β-phellandrene were the main volatiles in the cashew leaf-buds and leaves. The major volatile compounds of the red cashew ...

Background: Nowadays, colostrum has been known as a considerable and valuable by-product of large-scale dairy production in the world. The main objective of this study was to evaluate the effects of pasteurization, spray-drying and freeze-drying methods on bacterial loads and Immunoglobulin G (IgG) level of bovine colostrums. Methods: Colostrum samples were collected from the first milking pos...
