Background Stunting is impaired linear growth of children: they experience stunting in the first 1000 days after conception and is an indication of chronic malnutrition. Children under the age of two are regarded as the most vulnerable to malnutrition due to their rapid growth and greater exposure to infectious disease. Objective To assess the magnitude and associated factors of stunting among 6 to 23-month-old children in drought-vulnerable kebeles of the Demba Gofa district, southern Ethiopia. Methods A community-based cross-sectional study was conducted from February to March 2021. Systematic random sampling was used to select pairs of mothers/caregivers with children aged 6 to 23 months. A semistructured questionnaire and anthropometric measurement were used to collect the data. The data were checked coded and entered into Epi-data version 3.1 and exported to SPSS for Windows version 20.0 for analysis. Simple and multivariable linear regressions were conducted. The level of significance was declared at 95% CI and p-value < 0.05. Results The magnitude of stunting in the study area was 79(21.82%). Household dietary diversity [β = 0.217, 95% CI, 0.093–0.342], early initiation of complementary feeding [β = 0.444, 95% CI, 0.344–0.543], frequency of breastfeeding within 24 h [β = 0.217, 95% CI, 0.179–0.263] and child eating animal source food [β = 0.351, 95% CI, 0.196–0.506] were positively significant predictors of child height/length-for-age (HAZ). Conclusion The extent of stunting in the study area is relatively lower than that in regional and national reports, but one out of five children were still stunted. Therefore, health education on infant and young child feeding practices should be provided to mothers to reduce the problem.
Fresh and processed fruits are commonly used to prepare different industrial products with superior nutritional and health-promoting properties. Currently, the demand for processed-fruit products has motivated the rapid growth of fruit-processing industries, persuading them to produce an enormous number of by-products. Furthermore, people’s shifting dietary habits and lack of awareness of nutritional properties result in a large number of fruit by-products. The lack of knowledge about the value of by-products urges the exploration of proper documents that emphasize the health benefits of such products. Hence, this article was prepared by carefully reviewing the recent literature on industrial applications of fruit by-products and their nutritional and health-promoting properties. The use of fruit by-products in food industries for various purposes has been reported in the past and has been reviewed and described here. Fruit by-products are a good source of nutrients and bioactive components, including polyphenols, dietary fibers, and vitamins, implying that they could have an important role for novel, value-added functional food properties. Furthermore, fruit by-products are used as the substrate to produce organic acids, essential oils, enzymes, fuel, biodegradable packaging materials, and preservatives.
Some plant foods evolve defense mechanisms to protect themselves from predators by producing inherent chemicals as secondary metabolites such as cyanogenic glycosides, glycoalkaloids, glucosinolates, pyrrolizidine alkaloids, and lectins. These metabolites are beneficial for the plant itself but toxic to other organisms, including human beings. Some of these toxic chemicals are believed to have therapeutic benefits and are therefore used to protect against chronic health complications such as cancer. Inversely, short- and long-term exposure to significant amounts of these phytotoxins may end up with chronic irreversible negative health problems in important organ systems, and in severe cases, they can be carcinogenic and fatal. A systematic literature search of relevant published articles indexed in Google Scholar®, PubMed®, Scopus®, Springer Link®, Web of Science®, MDPI®, and ScienceDirect databases was used to obtain the necessary information. Various traditional and emerging food-processing techniques have been found to considerably reduce most of the toxicants in the food to their safest level. Despite their ability to preserve the nutritional value of processed foods, emerging food processing methods have limited application and accessibility in middle- and low-income countries. As a consequence, much more work is recommended on the implementation of emerging technologies, with additional scientific work on food processing methods that are effective against these naturally occurring plant food toxicants, particularly pyrrolizidine alkaloids.
Microwave processing is one of the novel food processing technologies that use electromagnetic radiation in the wavelength and frequency between 1 mm to 1 m and 300 MHz to 300 GHz, respectively. In this review, principles and various applications of microwave technology for food processing are addressed. A systematic literature search was conducted by using, Google Scholar and, Web of Science, Open access theses and dissertations on the principles and application of microwave processing of food were summarized. Additionally, references of each selected publication were examined to get more relevant articles. In microwave processing, the food material absorbs microwave energy directly, and internally, and converts it to heat. The technology is applicable for different unit operations in food industries such as cooking, heating, drying, pasteurization, sterilization, thawing, tempering, baking, blanching, and the extraction of important food biomaterials. Microwave processing is highly advantageous over conventional food processing techniques, in terms of retaining the nutritional content of the food and reducing processing time. Consequently, the breakthrough of the technology in food processing industry has been predicted before. However, the potential of microwave technology is not widely exhausted in Africa. It is associated with a lack of awareness, a priority setting on the application of emerging technologies for safe and high quality value added products; moreover, its high initial investment and operational power cost may become a bottleneck for food processing companies in Africa. Therefore, food innovation centres in Africa should drive high performance standards from technology adoption to improve the application of microwave technology in food industries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
