Cooked cured ham is a ready-to-eat food that is popular among consumers. Stored temperature has a key effect on the quality and shelf life of ham. In this work, the quality changes and shelf life prediction of cooked cured ham stored at different temperatures were investigated. Sensory evaluation, physical and chemical indicators, and aerobic plate count were determined. Results showed that high storage temperature of cooked ham accelerates quality deterioration. Partial least squares (PLS) regression analysis based on the variable importance for projection (VIP) identified nine important variables for predicting the shelf life of cooked cured ham. Compared with either PLS or back-propagation artificial neural network (BP-ANN), the hybrid PLS–BP-ANN model better predicts the shelf life of cooked cured ham using the nine important variables. This study provides a theoretical basis and data support for the quality control of cooked cured ham and a new idea for research on the shelf life prediction of cooked cured ham.

Experiments were done to determine the major genera and groups of microflora which grow on unwrapped and wrapped slices of watermelon stored at 5 and 25°C for up to 8 d. Changes in sensory qualities of stored watermelon were also monitored. Pseudomonas, Escherichia coli, Enterobacter and micrococci comprised the predominant microflora, regardless of storage temperature. Growth was slower on wrapped watermelon than on unwrapped watermelon. Subjective ratings for color, aroma, appearance, flavor and texture of unwrapped watermelon stored at 5°C decreased more rapidly than ratings for wrapped slices. Results from objective measurements of color suggested that dulling and darkening was most rapid on the surface of unwrapped watermelon, and this was attributed to more rapid oxidation of pigments when exposed to air. Objective measurement of firmness showed that wrapped watermelon retained structural integrity for a longer time than unwrapped watermelon; however, subjective ratings for texture were not correlated with these values, indicating that texture is less critical than color and flavor when overall judgments are made on sensory quality of stored watermelon.

Cooling Method

Vacuum pre-cooling technique was used as a rapid cooling method for leafy vegetables such as lettuce, spinach and so on. Experiments were carried out to investigate the effect of vacuum pre-cooling on physiological activities during cold storage. The results revealed that the increase in weight loss and membrane permeability was inhibited, and the sensory quality was improved. Meanwhile, the decompositions of chlorophyll and soluble solids were delayed. Taking all these into account vacuum pre-cooling treatment can significantly extend the shelf life of spinach.

(Study Of Quality Changes During Storage And Shelf Life Prediction Of Beledang Fish Chips In Rigid Polypropylene Packaging) ABSTRACT. This research aims to determine the quality changes during storage and shelf life of beledang fish chips in rigid polypropylene packaging. Observation of quality based on the moisture content and total microbes were done on 0 and 30th days at 25°C, 30°C and 35°C with 3 replicates at each storage temperature. Shelf life prediction of beledang fish chips based on moisture content changes at 25oC, 30oC dan 35oC was measured using Arrhenius Model. The result shows that there is a change in water content and total microbes in beledang fish chips during storage. At storage temperature of 35oC, the chips have moisture content changes and total microbes on the 30th day of storage which are 4% and 10 x 104Cfu. The shelf life of beledang fish chips in polypropylene rigid packaging at storage temperature of 25oC, 30oC and 35oC is 9 months 28 days, 10 months 3 days, and 10 months 8 days respectively.

Three Korean side dishes of seasoned beef soup, soybean sprouts and fried tofu were stored at 0, 3 and 10 C. Changes in sensory, physical and chemical indexes were compared with microbial quality deterioration for shelf life determination. For beef soup, shelf life, based on a microbial quality limit of 106 cfu/g, was comparable to that obtained from sensory quality. The primary quality factor criterion for seasoned soybean sprouts determining shelf life varied with storage temperature. For seasoned tofu, shelf life estimates based on a microbial criterion of 106 cfu/g represented a more conservative estimate than those based on sensory quality at 3 and 10 C. Microbial quality was generally to be a common and sensitive criterion for shelf life determination, thus a microbial growth model was used to estimate shelf life at different temperatures.

Improved quality control and prolonged shelf life are important actions in preventing food waste. To get an overview of the bacterial diversity of fillets from live stored mature Atlantic cod, bacterial isolates were identified before and after storage (air and vacuum) and freezing/thawing. Based on the load of dominating bacteria, the effect of different packaging methods and a short freezing/thawing process on prolonged shelf-life was evaluated (total viable counts, bacteriota, sensory attributes, and volatile components). Hand filleted (strict hygiene) cod fillets had a low initial bacterial load dominated by the spoilage organism Photobacterium, whereas industrially produced fillets had higher bacterial loads and diversity (Pseudomonas, Arthrobacter, Psychrobacter, Shewanella). The identified bacteria after storage in vacuum or air were similar to the initially identified bacteria. Bacteriota analysis showed that a short time freezing/thawing process reduced Photobacterium while modified atmosphere packaging (MAP; 60%CO2/40%O2 or 60%CO2/40%N2) inhibited the growth of important spoilage bacteria (Photobacterium, Shewanella, Pseudomonas) and allowed the growth of Carnobacterium/Carnobacteriaceae and Acinetobacter. Despite being dominated by Photobacterium, fresh fillets stored in MAP 60%CO2/40%N2 demonstrated better sensory quality after 13 days of storage than fillets stored in MAP 60%CO2/40%O2 (dominated by Carnobacterium/Carnobacteriaceae). Carnobacterium spp. or other members of Carnobacteriaceae may therefore be potential spoilage organisms in cod when other spoilage bacteria are reduced or inhibited.
