Natrella G, Gambacorta G, Faccia M. Application of Commercial Biopreservation Starter in Combination with MAP for Shelf-Life Extension of Burrata Cheese. Foods 2023; 12:foods12091867. [PMID: 37174405 PMCID: PMC10178730 DOI: 10.3390/foods12091867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 04/13/2023] [Accepted: 04/27/2023] [Indexed: 05/15/2023] Open
Abstract
Burrata is a fresh pasta filata cheese manufactured in Italy. Its demand on the worldwide market is constantly growing, and prolonging its shelf-life is an important challenge for the Italian dairy industry. In the present study, combining a commercial bio-protective starter and modified atmosphere packaging (MAP) was evaluated as a strategy to delay the spoilage of product quality. Three experimental samples of burrata were produced by experimental trials at the industrial level and stored for 28 days under refrigerated conditions. Two samples contained the protective starter but were packaged differently (under MAP and immersed in water), and one did not contain the starter and was packaged under MAP. A sample of burrata without a starter and immersed in water was also prepared and used as a control. The combination of MAP and bio-protective starter delayed the degradation of lactose and citric acid, used as indices of microbial activity. In fact, lower counts of Enterobacteriaceae and Pseudomonas were observed in this sample. In contrast, control burrata had the highest level of total Volatile Organic Compounds (VOC) at the end of the storage period, because of higher microbial activity. Even though all samples were judged to be unacceptable after 28 days from the sensory point of view, the sample with bio-protective starter under MAP had the best score after 21 days, obtaining a shelf-life extension of about 7 days with respect to control. In conclusion, the combination of MAP and protective starter culture could be an easy way to extend the shelf-life of burrata stored under correct refrigerated conditions.

The Effect of Modified Lysozyme Treatment on the Microflora, Physicochemical and Sensory Characteristics of Pork Packaged in Preservative Gas Atmospheres. COATINGS 2021.

Abstract
The aim of the study was to investigate the effect of modified lysozyme on the microflora, physicochemical and sensory characteristics of pork loin packaged in modified atmospheres and stored at 4 ± 1 °C. Different gas compositions (M1 65:25:10 O2:CO2:N2; M2 50:40:10 O2:CO2:N2; M3 80:20 O2:CO2) were used. The microbiological parameters (APC, Enterobacteriaceae, Pseudomonas spp., lactic acid bacteria), physicochemical indexes (pH, colour) as well as a sensory attribute, i.e., aroma were analysed. Meat samples were tested after five, 12, 19, 23, and 28 days of storage. Changes in the qualities of pork were determined throughout the storage. The proportions of polymeric forms, hydrolytic activity and hydrophobicity were determined in the lysozyme preparation. Modified lysozyme exhibited higher hydrophobicity and lower hydrolytic activity than lysozyme monomer. The colour parameters L* and a* were not considerably affected by the addition of modified lysozyme. The sample with the modified lysozyme was given the highest score for aroma. In comparison with the monomer, the modified lysozyme exhibited greater antibacterial effect, especially against Pseudomonas and Enterobacteriaceae. Microbial growth rates in the sample with modified lysozyme, packaged in an atmosphere with the highest content of CO2 (total plate count 4.59 log CFU/cm2; moulds and yeasts 2.17 log CFU/cm2) were lower than those observed in the sample without lysozyme packed under M1 and M3 (20−25% CO2). The use of an atmosphere with gas composition and modified lysozyme considerably extended the shelf life of pork. The combination of the atmosphere with the highest content of carbon dioxide (50% O2, 40% CO2, 10% N2) and modified lysozyme resulted in the best effect. This strategy extended the shelf-life by more than 20%, as compared with the control sample without lysozyme, packaged in an atmosphere of 50:40:10 O2:CO2:N2.

Journal of Food Science and Technology 2020; 58:2406-2419.

Abstract
The objective of the present study is developing a new technique for the preservation of natural cheese by the use of an edible biofilm based on sodium alginate in order to evaluate the effect of the essential oils (O. basilicum L, R. officinalis L. A. herba alba Asso. M. pulegium L.) incorporated in the film on the oxidation stability, microbial spoilage, physicochemical characteristics and sensory criteria. The cheese samples coated with sodium alginate incorporated by the oils showed moderate stability in terms of oxidative stabilities of proteins and lipids during storage. In addition, poor microbial growth (total aerobic mesophilic flora, yeasts and fecal coliforms) was observed in cheese samples coated with biofilm, also, the growth of Staphylococci Salmonella and Molds for all types of cheese were completely inhibited. Additionally, it was observed that the biofilm coating reduced the weight loss and hardness of the cheese comparing with the uncoated sample. The results of sensory analysis revealed that uncoated cheese, coated with sodium alginate and sodium alginate composed of oil of O. basilicum were the most preferred by panelists, in comparison with others. Therefore, it was concluded that this technique of coating cheese with edible film activated with essential oils is preferred and favorable by virtue of the effect of oils preserving the cheese without seriously affecting their organoleptic properties.
