The effects of 3 common handling procedures and mishaps (dropping, compression and trimming) applied to Chinese cabbage cv. Yuki [Brassica campestris L. ssp. pekinensis (Lour.) Olsson] were compared to unstressed control cabbages. Heads were mechanically stressed by dropping from 50 cm onto a hard floor, by prolonged compression under 3 kg of weight before storage, or by repeated trimming of the outer leaves during storage. Cabbages were stored at 2°C for 9 weeks. Market quality of cabbages was not affected by the mechanical stresses, but storage for 9 weeks reduced marketable quality. Heads that were repeatedly trimmed produced less ethylene at the end of the storage period compared to the start, and less ethylene than the other treatments (due to the removal of outer senescing and rotting leaves); however, marketable yield was not improved.

The aim of this work was to monitor quantitative and qualitative representation of probiotic strain L. casei 01 (Sacco, Italy) in dry femented sausages „Herkules“ taken from two different producers (A and B). Negative control susages without probiotics were also made at both producers, to monitor the differences between pH profiles of and lactic acid bacteria counts during fermentation and sto­ra­ge of dry sausages. The second objective of this study was to determine sensory quality of probiotic sausages in comparison with non-probiotic controls.The counts of L. casei and LAB in all sausages significantly (P < 0,01) increased during fermentation and storage period. Probiotic L. casei was well adapted to dry sausages environment and reached 106 CFU/g in both producers. No differences between pH profiles of probiotic sausages and controls without probiotics were observed.It was observed that all probiotic sausages had sensory properties near the traditional products.

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.

Changes in the dry matter and quality of pasture hay cured in different ways, and exposed in the paddock in various forms for up to eight months, were measured in two seasons at the Rutherglen Research Station in north-eastern Victoria. Comparisons were made with standing (dry) pasture at one extreme and at the other with hay cured in the conventional manner, baled, and stored under cover. Changes in dry matter in the curing period were small for conventionally cured hay under the conditions of the experiments. Relatively large losses (8 to 14 per cent of the cured hay) were attributable to baling. In the storage period, pasture left standing lost 68 per cent of its dry matter in three months of summer and its quality deteriorated markedly. All the forms of conservation reduced the rate of these losses, the effectiveness of a particular method depending largely on the degree of exposure of the hay to weathering. Hay baled and stored under cover was the best (6-8 per cent loss of dry matter m eight months with little change in quality). Bales stooked in the paddock were well protected for up to seven months (17 per cent loss of dry matter), and losses for windrows and cocks of loose hay were within reasonable limits (less than 45 per cent) for shorter periods over the summer and early autumn.

Statistical Results

The aim of this study was to evaluate various combination and effect of storage period on thequality of carrot apple blended jam at ambient temperature (18-25 °C). The treatments were CA0, CA1,CA2, CA3, CA4 and CA5. All the treatments were examined for physicochemical properties i.e., total solublesolids (TSS), pH, reducing sugars (%), percent acidity, non-reducing sugars (%), ascorbic acid (mg/100 g),as well as for sensory properties at fifteen days interval for a total storage period of 90 days. Significantincrease (P<0.05) were examined in TSS (67.45-70.40 °brix), acidity (0.64-0.80) and reducing sugars(16.64-27.78). While, significant decrease (P<0.05) were examined in pH (3.63-3.44), non reducing sugars(45.04-27.69), ascorbic acid (7.81-5.52 mg/100 g), colour (7.33-4.35), taste (7.40-4.12), texture (7.22-4.06) and overall acceptability (7.36-4.14). Statistical results concluded that treatment and storage has asignificant effect on the quality and stability of carrot pulp and apple pulp blend jam. Results revealed thatgood quality jam could be prepared with equal amount of carrot and apple pulp, which showed withminimum damage to physiochemical and sensory attributes among the other treatment even after 90 daysof storage.

There is a shortage of herbaceous peony cut flowers in the world market in late winter/early spring. The quality of these prestige flowers, when cultivated in warm climate regions and stored in cooling chambers during dormancy, is influenced by pre-dormancy, dormancy, and post dormancy conditions. In this article, various regimes of peony dormancy with constant and variable temperatures were studied. Containers with plants of cv. ‘Sarah Bernhardt’ were exposed to a pre-dormancy temperature of 15°C and, after two weeks, transferred to cooling chambers in order to keep dormancy under four constant or diurnal temperature regimes. On three different dates, plants from each treatment were transferred to a greenhouse for release from dormancy and the beginning of sprouting. During commercial harvest, data on height and thickness of flower stems, number of harvested flowers per plant, and dates of harvested flowers were collected. Using these data, the index of market quality of peony flowers was defined and regressed on dummy variables that reflected chilling regimes and dormancy duration. Statistically significant differences in market quality were shown between the treatments with the lower storage temperatures 20 C, 2-100 C, and 2-150 C, and the reference treatment with a storage temperature of 2 – 200 C. Statistically significant differences were also shown between the treatments with the shorter storage period of 6 weeks, 4 days or of 8 weeks, on the one hand, and the reference treatment with the storage of 9 weeks, 3 days, on the other. Close results were obtained for the treatments with the constant temperature of 20 C and with the diurnal alternating temperature of 2-100C. Therefore, growers can expect economic gains from saving energy during dormancy under a suitable temperature regime.

Aims: Fish is a product more and more consumed in Burkina Faso, especially in Ouagadougou. Poor sale and storage conditions can impact on the hygienic quality of fish. The objective of this study was to identify the contamination risks due to the sale and storage conditions of smoked, dried and fresh fishes. Study Design: A descriptive design was used to identify the different types and origins of fish on the markets in Ouagadougou and the practices and conditions of sale that could be sources of chemical and microbiological contamination. Place and Duration of Study: Relevant data was collated in Ouagadougou (Burkina Faso) from February 2019 to July 2019. Methodology: A survey was conducted among traders of dried and smoked fish from 50 markets and major sales sites in Ouagadougou. Data collection was done using a questionnaire developed with Sphinx Plus2 software. Results: The results indicated a higher proportion of men (75%) than women (25%) with an age between 21 and 45 years old were participated in fish trade. The fish encountered in the markets of Ouagadougou come from Sourou, Kompienga and Bagré, as well as from external suppliers such as Côte d'Ivoire, Mali and Senegal. The different types of fish sold were dried or smoked carp (36.67%), smoked catfish (23.33%), dried Nanani or Djêdjê wala (concorde) (13.33%), smoked Macharon (10%), smoked Racok (10%) and smoked eels or Roolgo in mooré (local language) (6.67%). The types of fish most purchased by consumers, in order, were: Carp, Catfish, Macharon, Nanani. In addition, the study detected risks of contamination of the fish, namely: exposure material consisting of tables and baskets, conservation at room temperature, storage period of 10 to 30 days, no training in hygiene, fish served with bare hands, exposed to dust and stray animals. Conclusion: In sum, the study revealed some characteristics of the fish industry in Ouagadougou and also risks of contamination of fish sold on the markets.
