The effect of curd cooking temperature (40 and 42°C), pressing, and ripening on textural and sensory properties of vacuum packaged semi-cooked ewe’s milk cheese was studied. Chemical and microbiological analyses, colour, texture, and sensory characteristics were determined. Curd cooking temperature and pressing influenced a<sub>w</sub>, moisture and salt-in-moisture content. Texture parameters were partially modified by pressing. On the contrary, cooking temperature resulted mainly in changes of cheese colour. Storage time was the most important factor in changing cheese characteristics, including sensory characteristics, whereas an increase of bitter aftertaste was observed during storage, likely due to packaging in a plastic pouch.

The aim of this study was to determine the effect of the addition of spices (garlic, rosemary, thyme, sage or clove) on the chemical and sensory characteristics of burgers elaborated with lamb meat from different locations (L: only leg; LNB 2/3 leg + 1/3 neck and breast). Formulation type (L vs. LNB) modified the chemical composition. L burgers showed lower values of fat, saturated fatty acids, monounsaturated fatty acids and higher moisture and polyunsaturated fatty acids content than LNB samples, with both types of burgers maintaining the nutritional indexes (P/S and n6/n3) within the recommended amounts. Nevertheless, the type of formula did not influence the sensory properties of lamb burgers. By contrast, the spice addition affected these characteristics over the period of time considered in this study. At the end of storage their global quality could be listed in the following order, from major to minor rate: Sage > Rosemary > Garlic > Thyme > Clove burgers.

Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage.

The study was undertaken with a view to explore the use of carrot pomace powder as well as beetroot pomace powder with whole wheat flour in the preparation of high fiber biscuits, to study its effect on the physico-chemical and sensory characteristics of biscuits. The Carrot Pomace Powder (CPP) and Beetroot Pomace Powder (BPP) were prepared through the process of convective dehydration and vacuum drying. All the data obtained were analyzed statistically to determine the level of significance of variation in observations caused by the changes in the biscuits formulations. The carrot pomace and beetroot pomace fortified biscuits contained greater amount of ash, crude fiber and moisture content than control biscuits but lower carbohydrate, protein, calorific value and pH. After fortification of fiber, product was found to be more acceptable in terms of physico-chemical and sensory characteristics.

This article looked at the quantity and storage time of attiéké produced and sold in the town of Daloa. It also examines the microbiological characteristics of attiéké-femme and attiéké-garba from this locality during storage. The study was carried out on the one hand through a field survey carried out on the producers and sellers. On the other hand, a sample was taken from 10 sellers of attiéké-garba and 10 sellers of attiéké-woman. The study found that the women producers sell 87% of their production in the city of Daloa and export 13%. In addition, attiéké can be kept for 2 days at the producers and beyond 2 days at the sellers before their stock runs out. Therefore, a weekly production of more than 200 kg for the majority of the producers is observed. Microbiological analyses showed high levels of germs (MAG: 6.106 CFU/g; Yeasts and moulds: 2.7.106 CFU/g) for attiéké-women and (2.106 CFU/g of GAM and 1.6.103 CFU/g of Yeasts and moulds) for attiéké-garba. Total coliforms and faecal coliforms were only found in attiéké-women. No salmonella was observed. In view of the results, it should be noted that female attiéké is the most contaminated type of attiéké.

Snails, a delicacy in most tropical communities, are highly perishable and seasonal. Employed preservative methods are highly temperature dependent, adversely affecting their nutritional value and sensory properties. This study was aimed at determining the effect of size and drying time on the rehydration and sensory properties of freeze-dried snails. Snails were sized into three categories with average weights: 7.59 g (quarter-sized), 14.41 g (half-sized), and 30.71 g (whole), and freeze-dried for 15, 20, and 25 h. The moisture content and percent rehydration of the dried samples were determined by standard methods and sensory properties assessed by an in-house panel of 30 using a 5-point hedonic scale. The moisture content of the fresh and freeze-dried samples ranged from 65.80 to 75.20% and 3.25 to 10.24%, respectively. Freeze-dried samples had higher percent rehydration (27 to 102%) than the control; smoked snails (21 to 32%). Size had a significant (P<0.05) effect on the rehydration ability of the samples with the half-sized and freeze-dried for 15 h samples having the highest. The freeze-dried samples generally had higher consumer preference than the control in all attributes assessed. The findings show that freeze-drying snails (approximate weight of 14.4 g) for 15 h could be a consumer-preferred alternative preservative method for extending the shelf life of snails.

Processing And Storage

Table olives are a pickled food product obtained by a partial/total debittering and subsequent fermentation of drupes. Their peculiar sensory properties have led to a their widespread use, especially in Europe, as an appetizer or an ingredient for culinary use. The most relevant literature of the last twenty years has been analyzed in this review with the aim of giving an up-to-date overview of the processing and storage effects on the nutritional and sensory properties of table olives. Analysis of the literature has revealed that the nutritional properties of table olives are mainly influenced by the processing method used, even if preharvest-factors such as irrigation and fruit ripening stage may have a certain weight. Data revealed that the nutritional value of table olives depends mostly on the balanced profile of polyunsaturated and monounsaturated fatty acids and the contents of health-promoting phenolic compounds, which are best retained in natural table olives. Studies on the use of low salt brines and of selected starter cultures have shown the possibility of producing table olives with an improved nutritional profile. Sensory characteristics are mostly process-dependent, and a relevant contribute is achieved by starters, not only for reducing the bitterness of fruits, but also for imparting new and typical taste to table olives. Findings reported in this review confirm, in conclusion, that table olives surely constitute an important food source for their balanced nutritional profile and unique sensory characteristics.
