Empirical estimation of skin resistance to water loss in amphibians: agar evaluation as a non-resistance model to evaporation
(Company Biologists Ltd, 2022-08-01)
Total resistance (r(t)) to evaporative water loss (EWL) in amphibians is given by the sum of the boundary layer (r(b)) and the skin resistance (r(s)). Thus, r(s) can be determined if the r(b) component is defined ...
Secagem de gel ágar.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2000-02-29)
Agar-agar is a hydrofilic colloid extracted from seaweed, mainly from algae Gelidium. It s used as culture medium in microbiology and as emulsificant, stabilizer and gelling in foods. Drying is an important operation in ...
Mathematical modeling of L-(+)-ascorbic acid delivery from pectin films (packaging) to agar hydrogels (food)
(Elsevier, 2018-10-13)
This paper focusses on the mathematical modeling of the ascorbic acid (antioxidant) release from a pectin edible film (packaging) to an agar hydrogel (food). The proposed model considers the viscoelastic properties of the ...

Insights into agar and secondary metabolite pathways from the genome of the red alga Gracilaria domingensis (Rhodophyta, Gracilariales)
(2022-01-01)
Gracilariales is a clade of florideophycean red macroalgae known for being the main source of agar. We present a de novo genome assembly and annotation of Gracilaria domingensis, an agarophyte alga with flattened thallus ...
Development and validation of a microbiological assay for determination of chlorhexidine digluconate in aqueous solution
(2013-01-01)
Chlorhexidine (CHX) is a broad-spectrum antiseptic that is used in many topical pharmaceutical formulations. Because there is no official microbiological assay reported in the literature that is used to quantify CHX, this ...

Structure characterization by means of rheological and NMR experiments as a first necessary approach to study the l-(+)-ascorbic acid diffusion from pectin and pectin/alginate films to agar hydrogels that mimic food materials
(Elsevier, 2015-11-09)
Pectin (P) and pectin–alginate (PAL) edible films, developed for antioxidant preservation, were placed on agar cylinders, mimicking food materials, in order to understand the release of l-(+)-ascorbic acid (AA) from the ...
