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.

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.

The article presents the study results of spelt wheat grain baking properties depending on fertilization and storage period. Europe (huskless) winter spelt wheat variety obtained by hybridization of Triticum aestivum L./Triticum spelta L. was studied. For fertilization, ammonium nitrate, ammonium sulfate, granular superphosphate, potassium chloride were used. Spelt wheat grain was stored for a year without air access at an unregulated temperature regime dry (moisture content during storage – 13.0–13.5 %) in airtight polyethylene sleeves in the conditions of usual storage. It was found that spelt wheat has a high response to the application of nitrogen fertilizers. The protein content increased from 18.6 to 22.8 % in P60K60 + N120 variant. The spelt wheat grain quality varied depending on the storage period. Thus, before storage, the gluten content was 41.1–50.4 % depending on the fertilizer variant. The lowest indicator was in the control variant and for P60K60 introduction – 41.1–41.2 %. In other fertilizer variants, the gluten content was at the level of 49.1–49.9 %. The largest was in P60K60 + N60S70 + N60 –50.4 % variant or 9 % compared to the control. Storage had a positive effect on the gluten content in spelt wheat grain as its content increased signifcantly. It can be explained by the post-harvest grain ripening, in the process of which the protein-proteinase complex changes due to the oxidizing action, oxygen, in particular. Thus, after storage for 30 days, this indicator was 41.8–52.1 % depending on the experiment variant. It was the largest when N60S70 + N60 was applied – 52.1 %, and the smallest in the variant with no fertilizers and with phosphorus-potassium (P60K60) fertilizer – 41.8–42.3 %. These indicators exceeded the gluten content before storage by an average of 1.2 abs. %. The content of protein and gluten-forming fractions is the highest after storage for 90 days. These indicators almost did not change after 180–270 days of storage. After 360 days they decreased to the grain quality indicators before storage. The gluten deformation index increased to 105–108 units of GSI instrument or by 4–8 % depending on the fertilization compared to fresh grain. Gluten moisture content decreased after 30 days of grain storage, and then increased to 68.0–69.8 % after 360 days, depending on the experiment variant. The grain acidity also increased from 3.0 to 4.0–4.1 degrees. Key words: spelt wheat, fertilization, storage, protein, gluten, dynamics, moisture content, acidity.

The moisture content of cigarette tobacco directly affects the smoking quality and storage period of cigarettes. The influence of the sealing property of cigarette packets on the moisture of the cigarette was studied, and a solution to improve the sealing property of the small package was provided. At the same time, the standard boundary for judging the packaging tightness of cigarette packets is calculated. Under different temperature and humidity environment, the air flow rate of the same packing box is higher than that of the 30-40mL/min interval. Improvement measures were applied to determine the packing seal value index of soft package cigarettes under certain conditions

This study aimed to assess the effect of different drying forms, environments, and storage periods on germination and sanitary quality of quinoa seeds cv. BRS Syetetuba. Seeds were submitted to drying in forced air circulation chamber at 30, 40, and 50 °C and in a suspended tray, in full sun, until they reached ±12% of moisture content. The observed drying data were adjusted to 10 mathematical models. The storage for 360 days was continuous in three different environments. Seeds were evaluated at 0, 6, and 12 months for germination, first count of germination, moisture content, and sanity tests. The experimental design was completely randomized, in a split split-plot scheme with four replicates. Among the studied models, Midilli was efficient in describing the drying curves of quinoa seeds. The storage environment influenced the loss of seed quality more than the drying temperature. The increased storage period caused a decrease on fungal seed incidence.

ABSTRACT The traditional system of collection and storage of Brazil nut compromises seriously the quality of these almonds as it contributes to the high incidence of contaminants, like fungi of the genus Aspergillus, which can produce aflatoxins. In this study, the objective was to evaluate the influence of the storage period in studied conditions, on the physicochemical characteristics and on the microbiological contamination of Brazil nuts. The experimental was designed as completely randomized, considering as treatments the storage period (0 - control, 30, 60, 90, 120 and 150 days) with four replicates of 3 kg of Brazil nuts each. The samples were submitted to physicochemical and microbiological analysis. It was observed that almonds submitted to the storage had their moisture content reduced by 78.2% at 150 days of storage, however, this reduction was not fast enough to avoid surface contamination by filamentous and potentially aflatoxins producing fungi. The critical period of contamination occurred on the first 30 days of storage when there was an increase of the studied fungi, as well as B1 and total aflatoxin. The studied storage conditions were four times more effective in reducing the product moisture content than the traditional methods, however, pre-drying is necessary to avoid contamination of the product.

In Kenya, spider plant (Cleome gynandra L.) has gained popularity among consumers due to its nutritional and medicinal values. In the local markets, bundles of leafy shoots as well as uprooted young plants are offered at fairly high prices in many parts of Kenya. Existing evidence suggests that spider plant is endowed with higher level of nutrients than its exotic counterparts. The leaves contain over and above the normal recommended adult daily allowance of vitamins A and C, calcium and iron. However, quality of spider plant seed is affected by one or more factors that cause negative response during seed handling and storage. The purpose of this research was to increase insight into how the seed quality of spider plant is affected by different packaging containers, seed moisture content and storage temperatures, with a view to finding out the optimal method of packaging and storing of these seeds. This study was carried out using seeds dried above silica gel to four target moisture levels: 20%, 10%, 5% and 2% moisture content. Dried seeds were sealed in aluminum foil packets and polyethylene packets and stored at three storage temperatures: ambient (22oC to 30oC), 5oC and minus 20oC for three and six months. After each storage period, seed samples were drawn and viability and vigour tests carried out. Data sets were factorially combined and subjected to Analysis of Variance (ANOVA)and descriptive analysis. Means separation was by Least Significance Difference (LSD).Levels of significance, means and standard deviations were obtained for various data sets. Seed stored for six months at 5% moisture content and minus 20oC recorded the highest seed quality. There were no significant differences between seeds packaged in aluminum foil packets and polyethylene packets. In this study, a germination of 85% was recorded for seed dried to 5% moisture content and stored at room temperature. Therefore, on the basis of these findings, farmers can dry their seeds at about 5% moisture content, package them in polyethylene (since readily available) and store at room temperatures for six months.
