Marine algae are becoming an interesting source of biologically active compounds with a promising application as nutraceuticals, functional food ingredients, and therapeutic agents. The effect drying (freeze-drying, oven-drying, shade-drying) extraction methods (shaking at room temperature, shaking in incubator 60 °C, ultrasound-assisted (UAE), microwave-assisted (MAE)) on the total phenolics c...

Bifidobacterium longum and Streptomyces peucetius are two totally different bacterial species with respect to environmental conditions and process objective. These were used as model organisms in this study. The objective of the B. longum process was to produce viable biomass suitable for use as food additive. The objective of the S. peucetius process was to produce a medically significant comp...

Cultures of P. chlamydosporia from infected nematode eggs in soil from different parts of the world have been freeze-dried and retained at Rothamsted Research, prior to use. Eight isolates (five collected from cyst nematode eggs and three from root-knot nematode eggs) were grown on 1.7% corn meal agar (Oxoid, Basingstoke, UK) at 25C prior to use. Chlamydospores used as inoculum were produced in...

background: freezing is a common way and one of the best methods of seafood preservation for long periods of time; however, the freeze thawing process may influence the quality of food. objectives: oxidation and denaturation of proteins, sublimation and recrystallization of ice crystals can cause changes in the quality of the frozen products. this study was aimed to evaluate the effect of three...

The effects of different drying methods (freeze drying, vacuum oven drying, and shade drying) on the phytochemical constituents associated with the antioxidant activities of Z. officinale var. rubrum Theilade were evaluated to determine the optimal drying process for these rhizomes. Total flavonoid content (TFC), total phenolic content (TPC), and polyphenol oxidase (PPO) activity were measured ...

This work aimed to establish an integrated approach investigate the total phenolic content and antioxidant activities of dried skim camel cow milk their fractions. The fractions were obtained by acid or enzymatic coagulation followed spray drying (inlet temperature/outlet temperature: 125 ± 2 °C/90 °C) freeze (−50 °C, 0.05 mbar) coupled not gamma irradiation (at 5, 11, 22 kGy). results showed t...

OBJECTIVE To determine the validity of the shake test for detecting freeze damage in aluminium-based, adsorbed, freeze-sensitive vaccines. METHODS A double-blind crossover design was used to compare the performance of the shake test conducted by trained health-care workers (HCWs) with that of phase contrast microscopy as a "gold standard". A total of 475 vials of 8 different types of World He...

The effects of two waste sources, red hybrid tilapia (Oreochromis sp.) and whiteleg shrimp (Litopenaeus vannamei), drying methods (freeze-drying oven-drying) on the proximate chemical composition bioflocs were investigated. In total, four kinds experimentally treated compared to identify best source method produce biofloc an acceptable nutrient value: freeze-dried (FDSBF), oven-dried (ODSBF), (...

Green banana flour (GBF) is considered a functional ingredient that could improve world's production sustainability. The drying method might influence the physicochemical and nutritional properties of GBF, affecting its performance in bread-making. study aims to determine impact freeze-drying oven-drying on gluten-free bread's quality. Freeze-dried (FDBF) bread had higher specific volume, resil...

BACKGROUND The analysis of red cell folate (RCF) depends on complete hemolysis of erythrocytes, and it is assumed that complete hemolysis is achieved by 10-fold dilution of whole blood with hypotonic solutions of 10 g/L ascorbic acid/ascorbate. This report challenges this assumption. METHODS The conventional method of erythrocyte lysis was modified to include saponin, a known effective hemoly...
