Challenges ahead for food science

Over the last decades, market forces have pushed many food companies into a process of continuous cost cutting and rationalization. The only way to escape this 'spiral of death' is to innovate.
  This presents new challenges to food technologists: they have to connect the right functional benefits to the emotional benefits to support brand strengths. To achieve the desired speed to market, companies should build skills to utilize the latest technology and learn to work in an open innovation environment.     

A PNA-array platform for the detection of hidden allergens in foodstuffs

A duplex PCR method was developed to simultaneously detect the presence of hazelnut and peanut in raw materials and commercial products. It was found to be able to specifically detect traces of the investigated products down to 50 pg of their target DNA.A PNA array device has been designed and implemented to be used in combination with the duplex PCR in order to investigate the presence of traces of potentially allergenic nuts in foodstuffs. A PNA probe for each target amplified by the duplex PCR was designed, synthesized and characterized. The PNA probes were then deposited on commercial slides in order to build a PNA array to be used for recognizing the PCR products; the concentration of the probes as function of the concentration of the target DNA, together with the specificity of the probes were investigated.The conditions optimized during the setting of the experiment were used to obtain the final version of the PNA array which was then used to test several commercially available foodstuffs claiming to contain or not to contain the targeted nuts.     

The influence of attachment to beef surfaces on the survival of cells of Salmonella enterica serovar Typhimurium DT104, at different a(w) values and at low storage temperatures

This study investigated the influence of attachment to beef surfaces on the survival, injury and death of stationary phase cells of Salmonella enterica serovar Typhimurium DT104, compared to cells free in solution. The effects on cells are considered at different a(w) values and low temperatures in relation to osmotic and cold temperature shock effects. Attachment of cells to meat surfaces prevented cell injury and death from hyperosmosis and low temperatures, compared to meat solutions. Storage of cells for 72h resulted in higher levels of cell death on cells attached to meat surfaces. The improved survival of cells in solutions was considered to be related to adaptation to osmotic stress as a result of exposure to a previous hyperosmotic shock and the ability of the cells to produce cold shock proteins. Pathogen cell growth at low temperatures is discussed in relation to the presence of low levels of NaCl. Finally the data is discussed in relation to pathogen survival on beef carcass surfaces during refrigeration.

Determination of mineral content in polymelt nonwoven fabrics

Minerals have been widely added to polyolefins during film- or fiber-manufacturing process to improve the processibility as well as to enhance the product properties such as thermal conductivity, surface roughness, fabric filtration efficiency, and fabric capacity of oil absorbency. Titanium dioxide has been traditionally added in PET fibers as a delustrant to reduce their transparency for some applications, e.g. clothing materials. Calcium carbonate has recently been added in polymelt – spunbond and meltblown – fibers to increase the fiber processibility and to improve the fiber properties and hence to achieve their final performance. It is crucial that the adding quantity should be controlled so the fabric strength will not be adversely reduced. Calcium carbonate is frequently over-added in polymelt fibers to take the advantage in business trading by weight. A method is essential to determine the mineral content in the polymeric materials. While trying to use the volume of the fabrics displaced by liquid to determine the density of fibers fails, we successfully used buoyant force of the fabrics in a liquid to precisely determine the volume of the fibers and to use it to calculate the mineral content in spunmelt PP fabrics. A gadget was designed to incorporate with a balance to form a density balance for this research. It was observed that only a single layer but not multiple layers of fabric is a key point to accurately determine its buoyancy in the liquid. Multiple layers contributed to a relaxation of the bending forces at the folding lines of the fabric, which attributed to an error in measuring the buoyancy of the fabric.     

Chemical composition and antioxidant activity of seeds of different cultivars of mungbean

ABSTRACT:  Seeds of 4 cultivars (M-1, M-6, NM-92, and NM-98) of mungbean [ Vigna radiata (L.) Wilczek] were investigated for proximate composition, antioxidant potential, fatty acids, tocopherols, and minerals profiles. Hexane-extracted seed oil content of the investigated cultivars of mungbeans ranged from 1.20% to 1.56%. Mungbean seeds were found to be a rich source of protein (20.97% to 31.32%). The contents of Fe, Cu, Mg, Na, K, Ca, and Zn were found to be 105.8 to 190.9, 4.8 to 6.3, 48.6 to 51.7, 382.6 to 562.7, 11.6 to 18.8, 359.2 to 482.9, and 24.9 to 47.2 mg/kg, respectively. The mungbean seeds contained linoleic acid in the highest amount, 340.5 to 465.7 mg/100 g of dry seed, followed by palmitic, oleic, linolenic, stearic, and arachidic acids: 278.1 to 401.2, 212.6 to 293.5, 188.7 to 236.8, 135.5 to 168.4, and 22.8 to 24.5 mg/100 g of dry seed, respectively. The seeds were found to be a rich source of tocopherols (α, γ, δ) ranged from 1.1 to 10.1, 60.7 to 80.9, and 4.6 to 11.2 mg/kg, respectively. Methanolic extracts of the seeds of the mungbean cultivars exhibited a good antioxidant activity as determined in terms of measurement of total phenolic contents (TPC) (0.62 to 1.08 g/100 g of dry matter), percent inhibition of peroxidation (49.8% to 89.2%), reducing power (1.19% to 1.45%), and bleaching β-carotene. The results of the present analytical study revealed these 4 mungbean cultivars to be a potential source of essential fatty acids, antioxidants, minerals and protein, all of which are linked with positive health benefits.     

Evolution in the surface modification of textiles: a review

The development of technical textiles allows the introduction of new, interesting and original multi-functionalities in textiles through development of the architecture of fibres, yarns and fabrics, their morphology and surface functionalization without altering their physico-chemical proprieties. This issue of Textile Progress reports different techniques used to impart new functionalities to the surfaces of textiles during the last decade. Following a short, context-setting historical introduction, the preparatory processes which need to be applied to textile matrices to make them clean and ready for functionalization are examined prior to a comprehensive review of techniques and research related to the development of functional textiles ranging from the more-traditional techniques through to more-recent developments. The challenge now is to bring new performance features to bear whilst maintaining environmental sustainability, chemical toxicological acceptability, high performance and cost effectiveness. In this context, the review reports on developments in the use of polymerization, nanotechnologies, plasma treatment, electrospinning, microencapsulation and sol gel techniques to impart novel properties to a textile surface such as water-repellent, flame-retardant and antibacterial properties.
