Presentation of textile pneumatic muscle prototypes applied in an upper limb active suit experimental model

This paper presents some prototypes of textile pneumatic muscles developed at the Department of Mechanical and Aerospace Engineering (DIMEAS) of the Politecnico di Torino. As an application, they are intended to be included in an ‘active suit’ useful for upper limb rehabilitation. They were realized with textile and soft materials in order to guarantee suitable wearability, confort, low weight, small dimensions as required to actuators used in active suits. This paper illustrated the experimental tests carried on these pneumatic muscles prototypes, a theoretical model from literature here applied to these muscles in order to calculate their stiffness, a preliminary active suit prototype for upper limbs rehabilitation purpose. The results obtained, both in terms of contraction and force developed with these prototypes, are highly satisfactory and the preliminary prototype of active suit realized for upper limbs works properly.     

Design and development of innovative textile pneumatic muscles

In recent years, the use of pneumatics in innovative actuation systems has led to the development, testing and first applications of nonconventional actuators such as pneumatic muscles. Like human muscles, pneumatic muscles can exert only traction forces, and offer a good power-to-weight ratio. The paper will present an investigation of new pneumatic muscles with a fabric structure. Lightweight, robust and efficient, these muscles can be used in a wide range of fields, from biomedical to industrial applications.

Development of QuEChERS-based extraction and liquid chromatography-tandem mass spectrometry method for quantifying flumethasone residues in beef muscle

A rapid, specific, and sensitive method based on liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) in the positive ion mode using multiple reaction monitoring (MRM) was developed and validated to quantify flumethasone residues in beef muscle. Methods were compared between the original as well as the EN quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based extraction. Good linearity was achieved at concentration levels of 5-30μg/kg. Estimated recovery rates at spiking levels of 5 and 10μg/kg ranged from 72.1 to 84.6%, with relative standard deviations (RSDs)<7%. The results of the inter-day study, which was performed by fortifying beef muscle samples (n=18) on 3 separate days, showed an accuracy of 93.4-94.4%. The precision (expressed as relative standard deviation values) for the inter-day variation at two levels of fortification (10 and 20μg/kg) was 1.9-5.2%. The limit of detection (LOD) and limit of quantitation (LOQ) were 1.7 and 5μg/kg, at signal-to-noise ratios (S/Ns) of 3 and 10, respectively. The method was successfully applied to analyze real samples obtained from large markets throughout the Korean Peninsula. The method proved to be sensitive and reliable and, thus, rendered an appropriate means for residue analysis studies.

Degradation of inosine-5′-monophosphate (IMP) in aqueous and in layering chicken muscle fibre systems: Effect of pH and temperature

Studies were carried out to assess the effect of pH and temperature on the degradation of major meat flavour precursor inosine mono-phosphate (IMP) in model systems. Breast and leg muscles from Indian domesticated layer chicken (Gallus gallus) were washed repeatedly with 0.1 M phosphate buffer of pH 6 to obtain pigment-free muscle fibres. Degradation of IMP in water and in muscle fibre-IMP systems were studied at 80, 100, and 120 °C under three pH (2, 7 and 11) conditions. The pH of muscle fibres was 6.2-6.4. The IMP content (mg/100 g) of fresh breast muscle (188.5) and its fibre (7.9) were higher (P?0.05) than fresh leg muscle (135.2) and its fibre (1.9). Inosine and hypoxanthine contents were also higher in breast than in leg muscles and their fibres. Degradation of IMP in both model systems was significantly influenced by pH and thermal treatment. In water systems, the degradation of IMP increased with temperature. Acidic pH caused greater degree of degradation than neutral or alkaline pH.

Lipid oxidation and antioxidant delivery systems in muscle food

Lipid oxidation accelerates quality deterioration in muscle-based foods (fish, red meat, and poultry), resulting in off-odors/flavors, color problems, texture defects, and safety concerns. Adding antioxidants is one approach to control lipid oxidation, and several delivery strategies have been applied, such as supplementing antioxidants to the feed, direct mixing into minces, or, for whole muscle pieces; spraying, glazing, and injection. However, some issues linked to these technologies hinder their wide utilization, such as low effectiveness, noncompatibility with clean label, and off-flavor. These shortcomings have promoted the development of new antioxidant delivery technologies. In this review, the main focus is on the principles, characteristics, and implementation of five novel antioxidant delivery methods in different types of muscle food products. Their advantages and drawbacks are also summarized, plus comments about future trends in this area. Among novel routes to deliver antioxidants to muscle foods are, for whole tissues, recyclable dipping solutions; for minces, encapsulation; and, for both minces and whole tissues, cross-processing with nonmuscle antioxidant-containing raw materials as well as applications of edible films/coatings and active packaging. Advantages of these technologies comprise, for example, low price, the possibility to control the antioxidant release rate, overcoming strong aromas from natural antioxidants, and allowing antioxidant-containing raw materials from the food industry to be valorized, providing an opportunity for more circular food production.
