Ultrasound treatment on saffron L corm: Impact on textural, morphological, and microbial properties and stigma- derived metabolite compositions.

This research aimed to assess the influence of ultrasound at a frequency of 37 kHz on various parameters of saffron ( L.) plants, including flowering efficiency, morphological, and textural properties, corm surface microbial population, and the concentrations of key secondary metabolites in saffron stigmas. Ultrasound was applied to saffron corms during two distinct growth stages, namely flower induction and flower initiation, utilizing varying sonication durations (0, 15, 30, and 60 min).

Investigating the effect of acoustic waves on spoilage fungal growth and shelf life of strawberry fruit.

The effects of acoustic waves on growth inhibition of food spoilage fungi (Aspergillus niger, Aspergillus flavus, Aspergillus parasiticus and Botrytis cinerea) on the medium and strawberry surfaces were investigated. Firstly, single-frequency sound waves (250, 500, 1000, 2000, 4000, 8000, 12,000 and 16,000 Hz) were induced on inoculated medium with fungi spores for 24 h and growth diameter of each mold was evaluated during the incubation period. In the second stage, the sound waves with two frequencies of 250 Hz and 16,000 Hz were induced on inoculated strawberries with fungi spores at 5 °C for different times (2, 4, 6, 8 and 10 days).

: chemical composition, thermal behavior, antioxidant and antimicrobial activities of leaf and gum hydroalcoholic extracts.

This is the first original study on chemical, thermal, antimicrobial, and antioxidant activity of the leaf and gum hydroethanolic (20:80 v/v) extracts of endemic for Iran. The ratio of solvent to the dried matters was 3:1 (w/w) and after filtering, the solvent was evaporated under vacuum (at 40 °C). Leaf extract contained greater phenolic and flavonoid compounds and thus higher DPPH scavenging and ferric reducing power.

Quantification of crocin, picrocrocin and safranal in saffron stigmas obtained from sounded corms with acoustic waves.

Introduction: Plant acoustic frequency technology (PAFT) is the effect or treatment of a plant with a specific frequency sound wave.

Objective: The sound waves with different frequencies and a sound pressure level 77 dB were emitted on the saffron corms in a controlled environment using aeroponic cultivation and the contents of crocin, picrocrocin and safranal in their produced stigmas were analysed by high-performance liquid chromatography. For this purpose, the corms were divided into two groups.

Characterization of polyamide-6/ propolis blended electrospun fibers.

Polyamide-6 (PA-6) nanofibers and PA-6/propolis ethanolic extract (EEP) blended fibers were prepared having electrospun their solutions in formic acid as solvent. The effect of concentrations of PA-6 and also EEP in polymer solutions on the morphology and physicochemical characteristics of their electrospun fibers was investigated. The analysis of FESEM images showed the mean diameter of fibers increased from 487- 682 nm with increasing PA-6 concentration in the range of 25-40 % w/v.

Detection of chloramphenicol using a novel apta-sensing platform based on aptamer terminal-lock in milk samples.

In this paper, a novel apta-sensing colorimetric platform for rapid detection of chloramphenicol (CAP) in raw milk was developed. The AuNPs are stabilized by short-sequences aptamers against salt induced aggregation and this is the base of most colorimetric aptasensors development. However, the statute shows low sensitivity for the long-sequence aptamers.
