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.

Food labelled with a “best before” date has a long shelf life. This study aimed to examine the respondents’ knowledge and understanding regarding the labelling on food products, as well as to assess the microbiological, physico–chemical and the sensory quality of selected durable food products on and after the date specified by the manufacturer. Two methods were used—a survey and laboratory tests. It was found that the majority of respondents have difficulty distinguishing and understanding the terms on the label and that a significant proportion of the respondents consume food products after the “best before” date. Laboratory tests of milk, pasta, mayonnaise and jam confirmed the microbiological safety of the products even six months after the “best before” date. Other features (texture, colour and sensory quality) slightly changed after one month for milk and mayonnaise (the colour had become more yellow) and after three months for pasta (its hardness had decreased) and jam (it had become browner). The possibility of extending the “best before” dates of selected durable foods could be considered, which could allow such products to legally be handed over to public benefit organisations, thereby reducing food wastage.

Positive Results

A scientific shelf-life study for Listeria monocytogenes in the typical Slovak cheese "bryndza" was performed in accordance with the requirements of the Commission Regulation (EC) 2073/2005. Based on the previous positive findings of L. monocytogenes in the final products, the producer decided to perform laboratory tests, the results of which would allow him a different evaluation of these positive results. Both the physico-chemical (pH, a<sub>w)</sub> and microbiological examinations of "bryndza" cheese stored at 5.8&ndash;6.2&deg;C were performed every two days till the end of the product shelf-life (7 days). Microbiological analyses were performed after artificial contamination of the final product with a mixture of three L. monocytogenes strains. The growth potential of L. monocytogenes was calculated as the difference in the counts of this bacterium between the last day and the first day of the test. The Slovak traditional "bryndza" cheese has been found not to support the growth of L. monocytogenes. Thus, the counts of L. monocytogenes must not exceed 50 CFU/g at the beginning and 20 CFU/g at the end of the product shelf-life in order to ensure its safety for the consumer.

The present investigations were conducted to develop a commercial appetizer (spiced squash) from mul-berry and its quality evaluation during storage. Different combinations of juice (20, 25, 30, 35 and 40%) and TSS (40 and 45 oB) were tried to standardize proper combination for appetizer. Out of 10 different treatment combinations of juice and TSS tried, appetizer recipe (A5) prepared with 40% juice, 40 oB TSS and 1.30% acid was found to be best on the basis of sensory and some physico-chemical characteristics of the product. The appetizer prepared by follow-ing the best selected recipe was packed in glass and PET (polyethylene terephthalate) bottles and stored for six months under ambient (20-25 oC) and refrigerated temperature conditions (4-7 oC). Overall effect shows that various quality characteristics like TSS, apparent viscosity, reducing sugars, and total sugars of appetizer increased from 40.00 to 40.63, 185.08 to 193.75, 28.37 to 31.80, 37.12 to 38.53 and other chemical characteristics like acidity, ascorbic acid, anthocyanins, total phenols and sensory characteristics scores of colour, body, taste, aroma, overall acceptability score decreased from 1.30 to 1.21, 5.18 to 3.75, 8.60 to 5.75, 58.22 to 49.23, 8.15 to 7.52, 8.00 to 7.30, 8.20 to 7.26, 8.00 to 7.03, 8.10 to 7.15, respectively during storage. However, quality of the product was retained better in glass than PET bottles under refrigerated condition as compare to ambient storage condition.
