“…In this study, passive‐MAP significantly slowed softening of the fresh pistachio kernels during cold storage. This could be attributed to the sustained high humidity inside the packaging that slowed weight loss and maintained cell turgidity, consistent with earlier reports on cherry tomatoes under active modified atmosphere conditions .

Background The effects of passive modified‐atmosphere packaging (passive‐MAP) on the postharvest quality of de‐hulled fresh pistachios (Pistacia vera L. cv. Kerman) stored at cold temperature (0 ± 0.5 °C) and 90 ± 1% relative humidity was investigated with fruits under ambient air condition as the control treatment. The fruit quality parameters measured included kernel firmness, color values (L*, a*, b*, h°, and C*), weight loss, fungal decay and marketability, ethylene production, respiration rate, and sensory characteristics at 0, 30, 60, and 105 days of storage. The carbon dioxide (CO2) and oxygen (O2) concentrations in the package headspace were monitored during storage. RESULTS A modified atmosphere of 0.95–3.35% O2 and 23.17–29.82% CO2 was achieved in the passive‐MAP treatment. Fruit respiration rates increased significantly relative to controls throughout storage (P ≤ 0.01). However, storage had no significant effect on ethylene production rates. Additionally, passive‐MAP‐stored fruits maintained firmness, shell lightness, kernel color, and sensory quality with minimum weight loss and fungal decay, compared with the control. CONCLUSION These results demonstrate storage life of fresh pistachios in passive‐MAP can be extended up to 105 days, compared with 30 days in ambient conditions. © 2019 Society of Chemical Industry

“…reported that passive MAP reduced fruit softening in cherry tomato cultivars ‘Alona’ and ‘Cluster’. The efficacy of MAP in retarding firmness losses during storage has been reported in a wide range of crops: for example, green bell pepper, fresh quinoa sprouts, blueberry, nectarine, Medlar, persimmon …”

Red, black and white seeds quinoa were germinated at 28 °C during 24 (G1), 48 and 72 h (G3). Red quinoa presented a higher percentage of germination with a value of 46% of germination at 72 h. Quinoa protein isolate (QPI) was obtained by alkaline extraction (pH 8.0) followed by an isoelectric precipitation (pH 4.5) from white, red and black quinoa seeds, germinated QPI-G1 or QPI-G3 and non-germinated QPI-NG, Chenopodium quinoa Willd var. Real. QPI-G1, QPI-G3 and QPI-NG were subject to a simulated gastric digestion (DG) and in vitro duodenal digestion (DD). The antioxidant activity was evaluated using the 1, 1-diphenyl-2-picryl hydrazyl (DPPH), azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and oxygen radical absorbance capacity (ORAC) methods. Gastric and duodenal digest of QPI-NG and QPI-G1 and QPI-G3 from white, red and black quinoa presented antioxidant activity. QPI-G1-DD of white quinoa presented the highest antioxidant activity with a DPPH value of 167.98 µmoL TE/g of digest, QPI-G1-DD of red quinoa with an ABTS value of 204.86 µmoL TE/g of digest and QPI-G1-DD of black quinoa with an ORAC value of 401.42 µmoL TE/g of digest. QPI-G3-DD of white quinoa presented higher antioxidant activity with a DPPH value of 186.28 µmoL TE/g of sample, QPI-G3-DD of red quinoa with an ABTS value of 144.06 µmoL TE/g of digest and QPI-G3-DD of black quinoa with an ORAC value of 395.14 µmoL TE/g of digest. The inhibition of reactive oxygen species (ROS) production in the zebrafish embryo model (Danio rerio) was evaluated. Protein profiles of QPI from white, red and black from germinated quinoa and non-germinated quinoa were similar with proteins between 10 kDa to 100 kDa with the presence of globulins 11S and 7S and 2S albumins.

“…Packaging proved to be significant for the shelf life of sprouts and microgreens [156]. In general, higher products' post-harvest performance is supported by a relatively high O 2 atmosphere equilibrated under modified atmosphere packaging (MAP) with high oxygen transmission rate films [2,157]. To this purpose, Wilson et al [158] reviewed innovative MAP technologies in fresh and freshly-cut vegetables including differentially permeable films with antimicrobial properties, elevated levels of non-traditional gases (i.e., argon, xenon), and smart packaging coupled to sensor technologies.…”

Sprouts and microgreens have attracted tremendous interest across multiple disciplines in recent years. Here, we critically review the most recent advances to underscore research prospects and niches, and related challenges, not yet addressed or fully pursued. In particular, we report a number of themes that merit special attention as a result of their relevance to plant science, nutrition, health, and zootechnics: (1) species not yet or inadequately investigated, such as wild plants, and fruit tree strains; (2) abiotic and biotic factors, and biostimulants, for elicitation strategies and metabolic engineering; (3) sanitization and processing technologies to obtain high-quality products; (4) digestive fate and impact of bioactive elements, antinutrients, and allergens on human nutrition; (5) experimental challenges to researching health benefits; (6) the opportunity to generate natural product libraries for drug discovery; and (7) sprouts in animal feeding to improve both animal health and the nutritional value of animal products for the human diet. The convergence of different themes involving interdisciplinary competencies advocate fascinating research pursuits, for example, the elicitation of metabolic variants to generate natural product collections for identification and selection of bioactive chemicals with a role as nutraceuticals, key constituents of functional foods, or interactive partners of specific drugs.
