Colorimetric Food Freshness Indicators for Intelligent Packaging: Progress, Shortcomings, and Promising Solutions.

The colorimetric food freshness indicator (CFFI) is a promising technology in intelligent food packaging, offering the capability for real-time monitoring of food freshness through colorimetric changes. This technology holds significant promise in mitigating food waste and enhancing transparency across the supply chain. This paper provides a comprehensive review of the classification system for the CFFI, encompassing colorimetric films and sensor arrays.

Starch/ polyvinyl alcohol/Brazilein film with enhanced stability by using medium-chain triglycerides emulsion for real-time meat freshness monitoring.

Brazilein natural dye (BR) and various concentrations of medium-chain triglycerides emulsion (EM) were added to a starch/polyvinyl alcohol (S/PA) base film to monitor beef and shrimp freshness in a novel intelligent food packaging film. The color of the BR solution changed from yellow to dark red at pH levels ranging from 2.0 to 12.

Nanoliposome-embedded alginate/κ-carrageenan double-network composite beads: Characterization, molecular interactions, texture, and gastrointestinal release of quercetin.

This study developed nanoliposome-integrated composite beads for the encapsulation and controlled release delivery of quercetin (Q) by incorporating various concentrations of quercetin-loaded nanoliposomes (QNLs, 96.9 nm diameter) into a sodium alginate/κ-carrageenan mixture. The microstructural, stability, textural, swelling, and gastrointestinal (GI) release properties of wet and dry beads were analyzed.

Fourier transformed near-infrared combined with chemometric analysis: Sustainable quantification of natural laxatives in Cassia plants.

FT-NIR and chemometrics are vital analytical tools for medicinal plant quality control. This study aimed to establish a rapid technique for quantifying sennoside A and B in Cassia plants (i.e.

Tribological Behavior of NiMoAl-Based Self-Lubricating Composites.

The present study focused on the development of NiMoAl-based self-lubricating composites using solid lubricants as the second phase by powder metallurgy. For this, CrAlC MAX phase, CrAlC-Ag, and MoS powders were mixed with the NiMoAl-based matrix and subsequently hot pressed to produce bulk composite samples. The average hardness and wear resistance of the matrix were found to be increased with the addition of MoS, CrAlC MAX phase, and CrAlC-Ag powder to the NiMoAl matrix.

Fluorescent carbon dots driven from ayurvedic medicinal plants for cancer cell imaging and phototherapy.

Ayurveda based nanomaterials are recently conceptualized phenomena for biomedical applications especially for imaging and treatment of in vitro cancer cell. Wide range florescent (blue to red emission) quantum dots are versatile materials for imaging and sensing applications. Various procedures and precursors of fluorescent carbon quantum dots (CQDs) are well established and documented in the literature.
