The purpose of this research was to blend quinoa (Chenopodium quinoa Willd.), buckwheat (Fagopyrum esculentum M?ench) and pumpkin (Cucurbita pepo L.) seed kernels at 40% level with wheat flour and to examine the effect of this blend on nutritional and sensory quality and also energy values of the pan bread. Hydrothermal preparation of these supplements is included. Chemical composition of the investigated materials, wheat bread and supplemented bread, was determined using relevant AOAC methods. Chemical composition of supplemented bread with an increase in protein, oil and crude fiber was superior in comparison with control wheat bread. Sensory properties of supplemented bread such as specific volume, appearance, crust and crumb texture, aroma-odor and color were evaluated and found excellent.

Protein Sources

In order to support the multiple levels of sustainable development, the nutritional quality of plant-based protein sources needs to be improved by food technological means. Microbial fermentation is an ancient food technology, utilizing dynamic populations of microorganisms and possessing a high potential to modify chemical composition and cell structures of plants and thus to remove undesirable compounds and to increase bioavailability of nutrients. In addition, fermentation can be used to improve food safety. In this review, the effects of fermentation on the protein digestibility and micronutrient availability in plant-derived raw materials are surveyed. The main focus is on the most important legume, cereal, and pseudocereal species (Cicer arietinum, Phaseolus vulgaris, Vicia faba, Lupinus angustifolius, Pisum sativum, Glycine max; Avena sativa, Secale cereale, Triticum aestivum, Triticum durum, Sorghum bicolor; and Chenopodium quinoa, respectively) of the agrifood sector. Furthermore, the current knowledge regarding the in vivo health effects of fermented foods is examined, and the critical points of fermentation technology from the health and food safety point of view are discussed.

The Relationship

Exploiting the relationship between the nutritional properties of seeds and the environment (E), genotype (G) and the GXE interaction, constitutes an essential analysis which contributes to broaden our knowledge regarding the control of the nutritional quality of seeds or of any other edible plant structure. This constitutes an important aspect when aiming at improving the nutri-tional characteristics properties of plant species, including those of Chenopodium quinoa Willd (quinoa) which is intended to be one of the main nutrient sources ensuring food security worldwide. This crop has gained popularity in the last decade achieving a fast-global expansion due to its excellent nutritional and agronomical properties together with the excellent adaptation shown to a wide diversity of agroclimatic conditions. Changes in the nutritional properties of quinoa seeds due to the influence exerted by the environment, the genotype, or their interaction, have been already described in previous works, but there is an important limitation in the anal-yses carried out, including the outcomes that can be translated into agronomical practices by which quality can be improved selecting the most adequate genotype. In here, several seed nu-tritional-related parameters from fifteen quinoa cultivars grown in a particular environmental context were analysed aiming at targeting compounds that can be determinants of seed quality varying with the genetic background. Important nutritional and agronomical differences were found among quinoa varieties highlighting the importance of choosing a proper genotype when cultivating quinoa.

School Food Environment

This paper examines the changes to procurement for school food environments in Canada as a response to changes to nutrition regulations at the provincial level. Interviews with those working in school food environments across Canada revealed how changes to the nutrition requirements of foods and beverages sold in schools presented opportunities to not only improve the nutrient content of the items made available in school food environments, but also to include local producers and/or school gardens in procuring for the school food environment. At the same time, some schools struggle to procure nutritionally compliant foods due to increased costs associated with transporting produce to rural, remote, or northern communities as well as logistic difficulties like spoilage. Although the nutrition regulations have facilitated improvements to food environments in some schools, others require more support to improve the overall nutritional quality of the foods and beverages available to students at school.

African Breadfruit

The extracted seeds of African breadfruit are identified to be extremely healthy whenever it is correctly processed. Therefore, the aim of the present study was to evaluate the effects of processing methods on the nutritional quality of African breadfruit seed. A qualitative phytochemical analysis including: Alkaloid, Flavonoid, Saponin, Tannin, Anthraquinone, Terpenoids, Steroid, and Cardiac Glycosides for the different fraction of African breadfruit seed was performed using a standard method. The result revealed the presence and greater amount of phytochemical for the raw fraction; seven in eight, six in eight for steamed fraction, and four in eight for boiled and roasted respectively. Anti-nutrient, Proximate, and Mineral Content were also conducted using standard methods. The amino acid composition was determined using High-Performance Liquid Chromatography (HPLC). The results of the present study revealed that anti-nutrients including Phytate, Tannins, and Oxalate were significantly p<0.05 reduced in the boiled fraction 5.47±0.15, 3.42±0.02 and 6.89±0.05, and highest in the raw fraction 7.77±0.01, 5.09±0.03 and 9.34±0.14. The proximate composition including; percentage crude fat, Ash, Carbohydrate, Fatty acid, and Energy value were significantly lower p<0.05 in the boiled fraction relative to the other fractions. Mineral contents; calcium, magnesium, sodium, potassium, and phosphorus were also significantly p<0.05 elevated in the boiled fraction relative to the raw, steamed, and roasted fraction. The amino acid composition was highest in the roasted and boiled fraction 57.350 and 56.978, and lowest in the steamed and raw fraction 35.754 and 28.748 respectively. Therefore, boiling (cooking) is encouraged for the preparation of African breadfruit seed.

Rates of food insecurity have increased substantially in the United States (US), and more families are turning to the charitable food system to help meet their needs. Prior studies have examined the nutritional quality of foods offered through food banks, but little is known about what government policies may shape the healthy food donation landscape. The purpose of this study was to review US federal policies that impact food and beverage donations to food banks and assess whether policies encourage healthy food donations. In spring 2020, two researchers independently reviewed federal food and beverage donation policies using predefined search terms in two legal databases. We identified six categories of policies based on the existing food donation literature and themes that emerged in the policy review. We identified 42 federal policies spanning six categories that addressed food and beverage donations to food banks. The largest category was “government programs,” with 19 (45%) policies. The next largest category was “donation via schools,” with 12 (29%) policies. However, no policies specifically addressed the nutritional quality of food donations. There is an opportunity for the federal government to strengthen food bank donation policies and improve the nutritional quality of donated foods and beverages.
