And Storage

In this paper, the effect of the packaging material and storage method on red raspberries produced at Reggio Calabria (Italy) was studied. For this purpose, the fruits were stored immediately after harvest in different conditions: in the fridge at 1 °C and in the freezer at −20 °C, using different packaging materials, two new patented films (nanoactive A) and (nanoactive B), one common packaging film (polyethylene terephthalate), and other fruits were left without any packaging material. Chemical parameters were analysed at harvest to have the initial characteristics without any conditioned storage and to distinguish the post-harvest effect on the fruits, then daily for storage in the fridge and monthly for storage in the freezer. The aims of our project were first to determine the qualitative characterization of these red raspberries, the optimization of their shelf-life during time in the fridge or freezer, using the different types of packaging materials and finally to highlight the usefulness of the new patented packaging materials. Nanoactive A film showed the best shelf-life in the fridge, and after 14 days the values, given as mg/100 g fresh weight, were: total phenolics (166.70), monomeric anthocyanin content (50.82), flavonoids (24.64), ascorbic acid (32.42), and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay (95.93).

Polymer films of rice starch/Polyvinyl alcohol (PVA) were prepared by casting method. Different blends were made varying the concentration of rice starch and PVA. Tensile strength (TS) and elongation at break (Eb) of the prepared films were studied. Films made up of rice starch and PVA with a ratio of 2:8 showed highest TS. 10% sugar was added with highest TS giving four composition of Starch/PVA blend in order to increase TS and Eb. Films made up of rice starch and PVA and sugar with a ratio of 1:8:1 showed highest TS and Eb and the recorded value was 14.96MPa and 637% respectively. The physico-mechanical properties of the prepared sugar incorporated films were improved by grafting with acrylic monomer with the aid of UV radiation. A formulation was prepared with monomer, methylmethacrylat in methanol, and a photo initiator. The highest TS of the grafted films were recorded and the value was 16.38 MPa. The water uptake and weight loss in both soil and water of the grafted films are lower than the non-grafted films. The prepared films were further characterized with stereo micrograph and XRD. Finally, the produced film can be used as biodegradable packaging materials for shopping and garbage bags that are very popular and environment friendly.

Fresh Food

The demand for increasing the shelf life of fresh food as well as the need for protecting the food against foodborne infections warrant the demand for increasing the shelf life of fresh food. The incorporation of nanoparticles into the packaging material can enhance the preservation of perishable foods. Silver nanoparticles (AgNPs), in particular, have antibacterial, anti-mold, anti-yeast, and anti-viral activities can be embedded into the biodegradable packaging materials for this purpose. This study focuses on antimicrobial packaging materials for food by mixing the extracts of different plants with silver nitrate and depositing this mixture as a layer on the blotting papers, which are thick sheets of paper made of cellulose. Because the blotting papers are highly absorbent and porous, silver nitrate solution along with the plant extracts can be easily applied and allowed for in situ synthesis of AgNPs. Subsequently, these papers were analyzed and characterized using scanning electron microscopy, transmission electron microscopy, atomic absorption spectroscopy, and energy dispersive X-ray analysis. The coated paper exhibited good antibacterial activity against Escherichia coli and Staphylococcus aureus. Furthermore, the coated paper when used as a packaging material for tomatoes and coriander leaf, the shelf life was extended to about 30 days and 15 days respectively. The prepared cost-effective silver packing material can be used in food packaging for various perishable foods.

Fresh Cut

Fresh mushrooms have a very short shelf life, of 1 – 3 days because of their high respiration rate and lack of cuticles that protect the plant from external factors. In the case of fresh-sliced mushrooms, they will be more susceptible to spoilage reactions due to the increase in respiration rate as a result of a broader surface area. Conventional packaging materials can not meet the requirements for modified atmosphere packaging of fresh-sliced mushrooms. One of the techniques to extend the fresh-cut produce shelf life is the passive modification of modified atmosphere packaging technology. For highly respiring fresh-cut produce such as fresh-sliced mushrooms, the permeability properties of the polymeric materials might not be enough to provide an equilibrium gas concentration in the passive modification of modified atmosphere technology. In this case, the microperforated packaging materials can be used for passive modification of fresh-cut produce. But the microperforation process needs a design for the application of the appropriate number and diameter of microholes to meet the requirements of passive modified atmosphere packaging. For this reason in this research, the design of the microperforation process to be used in passive modified atmosphere packaging was based on the diameter and the number of microholes, and the shelf life of fresh-sliced mushrooms was determined. The samples were stored at 15 °C/80% RH, and pH, color, weight loss, textural, sensorial, and microbial analysis were performed periodically during storage. It was determined that the empirical equation used in this research can be applied to microperforated packaging design for fresh-sliced mushrooms. The shelf life of the fresh-sliced mushrooms packaged with microperforated packaging material was 8 days, while it was less than 7 days (4, 5, or 6 days) when packaged with non-microperforated packaging material. This result shows that the use of microperforated packaging material is effective in extending the shelf life of fresh-sliced mushrooms.

This study was carried out in 2017 at the Federal University of Agriculture, Makurdi Nigeria. The study was aimed at evaluating the effect of packaging materials and storage period on the vigor parameters of some selected varieties of soybeans in Makurdi. The experimental design was 3x5x6 factorial CRD comprising 3 varieties, 5 storage periods and 6 packaging materials by 3 replicates. Samples were collected from National Cereal Research Institute, Yandev sub-station. The soybeans were cleaned, dried and the moisture content noted. Five hundred grams was measured into the various packaging material stored and at Strategic Grains Reserve, Federal Ministry of Agriculture Makurdi. The seeds in storage was sampled periodically (2, 4, 6 and 8 months) to determine quality by conducting standard germination test with 100 seeds (100 seeds/rep). The investigation revealed that V3 (TGx 1448-2E) stored for 2 months had the highest Shoot seedling length while V1 (TGx 923-3F) stored for 8 months had the least shoot seedling length. Soybeans stored in cloth had a very high Shoot seedling length at 2 months but dropped thereafter and turned out to be the lowest at the end of the storage period. V2 (TGx 1904-6F) stored in laminate paper produced the longest Shoot seedling length and also produced the shortest with V1. The seedling root length was longest in V3 stored for 2 months and least in V1 stored for 8months.Soybeans stored in cloth for 2 months produced very high SRL 2 months but dropped to 0.00 at the end of the storage period. V2 did better in LDPE than all the packaging materials. V1 had the shortest SRL in soybeans stored in bottle. The highest seedling vigor was recorded in V3 stored for 2 months while the lowest seedling vigor was recorded in V1 stored for 8 months. V2 in plastic container had the highest seedling vigor whileV1 in plastic had the lowest. However, significant differences were observed at (P< 0.05) in the interaction effect. In the present study, LDPE proved to be the best packaging material and the variety that had more resistance to deterioration was V2 (TGx 1904-6F). Soybeans that are stored at ambient should be in storage material that are impervious to air and moisture otherwise the seeds will lose viability and vigor. In addition, varieties that are prone to fast deterioration should not be stored longer.

The interest in phenols and anthocyanins has increased due to their antioxidant properties and to their potential usage as dietary antioxidants in human nutrition. Total phenols and anthocyanin content, composition and stability in berry extracts of blackcurrant interspecific hybrids, and antioxidative activity of extracts was evaluated. Berries of interspecific hybrids accumulated 530 to 614 mg 100 g(-1) FW of total phenolic compounds, while 621 mg 100 g(-1) FW of phenolics was established in berries of control Ribes nigrum cultivar 'Ben Tirran'. 'Ben Tirran' berries accumulated 444 mg 100 g(-1) FW of anthocyanins and higher amount was identified in berries of interspecific hybrids No. 11-13 (R. nigrum × R. petraeum) and No. 57 (R. nigrum × R. aureum), 522 and 498 mg100 g(-1) FW respectively. Berry extracts of hybrid No. 11-13 distinguished by the highest antioxidative activity (80%) and it was higher than antioxidant activity of 'Ben Tirran' (70%). Antioxidative activity of all tested berry extracts (70-80%) was twice higher compared to synthetic antioxidant BHT (39%). However correlation between phenolics or total anthocyanin content and antioxidative activity degree was not established. Amount of cyanidin 3-O-glucoside and cyanidin 3-O-rutinoside in berries of hybrids No. 57, No. 11-13 and No. 8 ((R. nigrum × R. americanum) × (R. nigrum × R. americanum)) was higher than in berries of 'Ben Tirran'. It was established that cyanidins are more stable anthocyanins in all studied temperature and irradiation conditions. Therefore interspecific hybrids No. 57 and No. 11-13 were the most agronomically valuable hybrids.
