A new approach to predict the fish fillet shelf-life in presence of natural preservative agents

2017

Three data sets concerning the behaviour of spoilage flora of fillets treated with natural preservative substances (NPS) were used to construct a new kind of mathematical predictive model. This model, unlike other ones, allows expressing the antibacterial effect of the NPS separately from the prediction of the growth rate. This approach, based on the introduction of a parameter into the predictive primary model, produced a good fitting of observed data and allowed characterising quantitatively the increase of shelf-life of fillets.

Squid (Sepia officinalis) stored in active packaging: chemical and microbiological changes

2005

The effect of modified atmosphere packaging (MAP) with and without a moisture adsorbent, on the quality of squid (Sepia officinalis) during chilled storage, was evaluated. Chemical and microbiological tests were carried out to measure the amount of spoilage and the resulting loss of fish freshness during 12 days of storage at 3°C. After 11 days, trimethylamine nitrogen (TMA-N) increased from 0.4 mg/100 g in fresh samples to 24 mg/100 g in MAP with adsorbent and 35 mg/100 g in the other samples. Total volatile basic nitrogen (TVB-N) increased from 18 mg/100 g in fresh samples to 112 mg/100 g in MAP with adsorbent and 158 mg/100 g in control samples. Counts of aerobic psychrotrophic microorga…

Effects of xanthan gum and calcium ascorbate treatments on color and nutritional quality of fresh cut pear fruit

2023

Edible coatings may be used to extend the shelf life of fresh-cut fruit products by controlling respiration and transpiration reducing overall quality decay. In this study, the effects of xanthan gum, combined with calcium ascorbate treatment, on color and nutritional quality of fresh-cut pear fruit were investigated. Fresh-cut pear fruit were processed with dipping for 4 different treatments: 2% xanthan gum solution with 2% calcium ascorbate (XAC); 2% xanthan gum solution (XAN); 2% ascorbate calcium solution (CAL) and distilled water for control (CTR). Fruit treated were stored at 5°C for 3, 5, 7 and 10 days. At each storage period, visual quality and flavor score, ascorbic acid and phenol…

Valutazione della shelf-life e dei parametri di qualità della Vastedda della valle del Bélice sottoposta a quattro differenti packaging

Negli ultimi anni si è diffuso un interesse crescente verso la qualità e la sicurezza alimentare, cosi come è aumentata la richiesta di prodotti naturali, in particolare quelli certificati da un marchio di qualità [Denominazione di Origine Protetta (DOP), Indicazione Geografica Protetta (IGP), Specialità Tradizionale Garantita (STG)] e quelli insigniti del riconoscimento di indicazione geografica e specialità garantita conferiti dalla Comunità Europea per promuovere e proteggere la qualità delle produzioni agroalimentari. La stretta correlazione di questi prodotti con il territorio e l’utilizzo di strumenti e tecniche di produzione tradizionali conferiscono al prodotto finale caratteristich…

THE MARKET FOR ALTERNATIVE SPECIES OF SHRIMP (PARAPENEUS LONGIROSTRIS) MINIMALLY PROCESSED TO INCREAS THE SHELF LIFE

2012

A reason that has put at the center of attention the crustaceans has been the growing demand for fast food products to which these fishes are particularly suitable. This paper proposes for the first time the use of the species of shrimp Parapeneus longirostris of the Mediterranean sea to realize precooked trays of V range and analyze the evolution of the process of melanosis with respect to commercial products in general coming from the Atlantic Ocean.

Frigoconservazione ed edible coating per la conservazione post-raccolta dei frutti della pesca Settembrina

2018

Da quanto emerso dai dati strumentali, l’applicazione del rivestimento a base di Aloe sui frutti di pesca “Settembrina”, sia in maniera singola che congiunta con 1 MCP, consente di rallentare i processi metabolici, permettendo, quindi, il mantenimento del colore dei frutti nel tempo e prevenendo la degradazione di tutti i composti nutrizionali e bioattivi utili a conferire al frutto serbevolezza e pregevoli caratteristiche organolettiche. Quanto riscontrato, si potrebbe tradurre in un vantaggio per il produttore che, usufruendo di una tecnologia semplice ed ecosostenibile dal punto di vista ambientale, potrebbe offrire al consumatore frutti dalla elevata shelf life con elevati standard qual…

Polyphenols from halophytes and modified atmosphere packaging improve sensorial and biochemical markers of quality of common dolphinfish (Coryphaena …

2016

Quality and shelf-life of whole and filleted Coryphaena hippurus, stored with modified atmosphere packaging (MAP) and natural antioxidants from halophytes (HAL), were investigated. Fillets were divided into control, simply sealed in trays; MAP, preserved by modified atmosphere (45% CO2, 50% N-2, 5% O-2); and MAP-HAL, pretreated with antioxidants and preserved by MAP. Whole and filleted fish were stored at -1 +/- 0.5 degrees C for 18days. The quality of the samples was analyzed at the time of packaging and after 3, 6, 9, 12, 15, and 18days. The MAP and MAP-HAL groups maintained the best sensorial profile, pH, and drip loss with respect to the untreated fillets. Higher levels of total volatil…
