Isothiocyanates (ITCs) contained in purees extracted from wasabi (Wasabia japonica (Miq) Matsum) can be used to manufacture a range of interesting spicy foods. In New Zealand, local manufacturers are showing interest in producing various forms of processed wasabi based sauces. However, isothiocyanates have been shown to degrade quickly in some situations. Therefore, in this study, the stability of allyl ITC was investigated in three wasabi flavoured products stored at four different temperatures (4, 10, 20 and 30°C) for 22 weeks. Two creamy (mayonnaise and tartare) sauces and a non-creamy sauce were prepared from an original recipe and flavoured with a known volume of "wasabi oil". Two types of pouches (clear and metallic plastic) were used to store each product and allyl ITC content was measured in the stored sauces at two week intervals. The initial level of allyl ITC found in mayonnaise, tartare and smoky tomato sauces were 415.3, 411.4 and 144.7 mg/ kg respectively, prior to storage. Temperature showed a strong influence in reducing allyl ITC (P=0.005 to <0.001) but no significant effect was identified for the two types of packets used. The non-creamy smoky tomato sauce was very unstable at 10°C or higher temperatures and the allyl ITC contents reduced rapidly with increasing storage temperatures. For instance, at 30°C, a 66% loss occurred by week 2 and a 90% loss occurred by week 6 in the smoky tomato sauce. However, mayonnaise and tartare sauces had a shelf life of 8 to 9 weeks with only a marginal reduction in allyl ITC (2% overall) at all the stored temperatures (4-30°C). These creamy sauces were characterized by a sudden fall in 10 weeks ending in a 69-70% loss of allyl ITC at 22 weeks. No microbial growth occurred in any of the sauces stored at any of the temperatures during the course of this storage experiment though very small change of colour was noticed for the sauces when stored at 30°C.

Development retort pouch packaged Ramasseri idli was undertaken with specific objectives of standardisation of thermal process in retort pouch package, shelf life study and quality evaluation. The Ramasseri idli, an indigenous cereallegume based food of south India, was procured and packaged in retort pouches with one idli in each pouch. The idlis were pasteurized at different time temperature combinations to achieve desired F0 values (110°C for F0=3 min, 110°C for F0=6 min 100°C for F0=3 min, 110°C for F0=6 min). After thermal processing the pouches were stored for shelf life studies under ambient storage (28°C) and refrigerated storage (7°C). The processed product was analysed for microbial and physico-chemical qualities viz; moisture content, pH, water activity, colour and texture using standard procedure at regular intervals. Based on physico-chemical characteristics and sensory evaluation, the thermal processed Ramasseri idli at 100°C for F0=6 min and stored under refrigeration showed best results up to three week of storage among the four treatments. The microbial analysis also showed that the product was safe up to 3 weeks of storage.

Knowing the potential of fish waste for the preparation of pâtés, there is the possibility of adding greater sustainability to the aquaculture sector. The aim was to prepare pâtés from fish processing residues with the inclusion of smoked fishmeal and evaluate their sensory, microbiological, physicochemical, and shelf-life characteristics. Three treatments were used: pâté without fishmeal inclusion (PSF), with smoked salmon carcass meal inclusion (PFSD), and smoked tilapia carcass meal (PFTD). The inclusion of the flours reduced the moisture, carbohydrate, and water activity. However, they increased the ash, salt, and collagen content. The lipid content was higher for the PFSD. The PSF showed peak oxidation at 15 days and the PFSD and PFTD around 45 days over the course of the 90-day shelf-life. The luminosity and b* coordinate were lower for PFTD, while the a* coordinate was higher for PFSD. Only the b* coordinate showed changes in PSF and PFSD throughout the 30 days of shelf-life, and its color tended to yellow at 15 days. The sensory analysis did not differ statistically between treatments (p > 0.05) for all attributes, except color, where the highest score was attributed to PSF. As for the overall impression, PSF also obtained the highest score, which may be associated with its color. By including fish flours, the nutritional composition and color of the tilapia-trimmed pâtés are changed, achieving an average acceptance level of 67%.

Surface Crystal

A simple, non-destructive method for estimating the extent of crystal development as white specks on the surface of colored Cheddar cheese is described. This method involves photocopying the surface of the cheese with a photocopier set at an exposure calibrated to clearly show the crystals. The photocopies of the cheese surface are then compared to a series of photocopies showing designated increases in crystal growth. Crystal development was rated as follows: 0 = no crystals, 1= light, 2 = medium, 3 = heavy, and 4 = very heavy to encrusted crystal development. The method does not disrupt or destroy the environmental conditions existing in the cheese package, allowing extended shelf life studies to be done on the same piece of cheese. However, the photocopy technique may not work as well with white cheese or cheeses without flat surfaces.
