AbstractDrying and storage methods are fundamental for maintaining the grain quality until processing. Therefore, the aim of this study was to evaluate the associations of the drying temperature with storage systems and conditions as a strategy for preserving the quality of maize grain postharvest on laboratory and field scales. An increase in temperature accelerated the reduction in grain moisture, but increased the deterioration. The wetting during the storage period reduced the grain quality. Hermetic and aerated storage systems maintained the chemical quality of the grains. The control with healthy and whole corn dried at 80 °C and stored in silos with natural aeration provided a satisfactory quality, equivalent to those of controlled drying and storage under airtight conditions and at low temperatures. Different conditions of drying and storage of corn on the laboratory and field scales were evaluated, which provides an appropriate management of these operations to maintain the grain quality.

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.

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.

This study includes the investigation of the chemical properties such as pH value anda*-value, sensorial evaluations, residual nitrite and the oxidation level of Chinese-style sausagered sausage, which have been produced by both reducing the nitrite level ( 50mg/kg, 100mg/kg and 150mg/kg) and adding tomato powder ( 0%, 2% and 4%). According to the results, 100mg/kg of nitrite together with 2% tomato powder is better. Then the sausages produced with 100mg/kg nitrite and 2% tomato powder, along with sausage which produced with only 150mg/kg of nitrite are stored at 4 °C for 45 days. It was observed that addition of 2% of tomato powder increased degradation of nitrite and decreased the level of oxidation. This study provides a potential solution for nitrite substitute in meat products.

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.

Tomato Powder

The effect of storage materials on the quality of tomato powder was studied. Fresh, firm and matured red tomatoes were washed, sorted and sliced to a uniform thickness of 5mm. The sliced tomatoes were pre-treated by dipping in 1% calcium chloride (CaCl2) and 0.2% potassium metabislphite (KMS) solution for 10 minutes at room temperature. 200g each of the sample was dried at temperatures of 600C until equilibrium moisture content was attained. The dried tomatoes were ground into powder and stored in Black polyethylene [BPE], White polyethylene [WPE], and Laminated Aluminium Foil [LAF] pouches for 6 weeks. The moisture content, crude protein, crude fibre, fat, total ash, and vitamin C of the tomato powder were determined using the method prescribed by AOAC. The carotene contents were determined by HPLC. The proximate analysis was repeated after 2 weeks, 4 weeks and 6weeks of storage.  There was an increase in moisture content and ash content after 6 weeks of storage while a decrease in value of protein, fat and vitamin C content occurred after the storage period. All the parameters measured were best retained by the laminated aluminium foil (LAF) compared to black polyethylene (BPE) and white polyethylene (WPE) packaging material for the entire period of the study.
