Authors:Hartwig Schulz Pages: 20 - 20 Abstract: For some years, superfoods have been very much in vogue, especially among younger people who often get their nutritional knowledge from various social media channels. It is therefore very positive that the author Reinhild Berger has taken on this important topic and critically examines the most popular and currently most advertised products in her entertainingly written “mini textbook”. In particular, the author takes a closer look at the following plant-based raw materials and the preparations made from them: Açai berries, acerola, algae species such as chlorella and spirulina, aloe vera, amaranth, aronia, buckwheat, camu camu, chia seeds, coracorn, curcuma, psyllium husks, fonio, goji berries, pomegranate, hemp seeds, clinoptilolite, coconut oil, kombucha, MCT oil, papaya, quinoa, teff and zeolite. The author tries to determine what is behind the products advertised as "superfoods" and how the suppliers succeed in appealing to their respective clientele with clever marketing. For example, it is stated that health-related claims about food in the European Union are subject to the requirements of the Health Claims Regulation and therefore the respective "superfoods" are often advertised very imaginatively by the respective marketing departments. Furthermore, the author notes that the composition of food supplements enriched with "superfoods" is often not precisely known and, moreover, the claimed health benefits are not always scientifically proven. It is also criticized that the vitamins contained in food supplements are often synthetic additives, although the advertising of the products indicates that only natural raw materials have been used. The author even warns that "superfoods" might be contaminated with harmful substances and are comparatively expensive compared to domestic vegetables and fruits. In addition, it is pointed out that especially exotic foods involve an increased risk of food allergies or intolerances and that undesirable interactions with medicines may be also possible. In her critical observations, however, the author fails to mention that superfoods can certainly enrich the diet and provide completely new flavour experiences, even if a significant added health value, when compared to domestic vegetables and fruits, cannot always be expected. Unfortunately, the author does not address the fact that some of the "superfoods" listed in the book not only serve a healthy diet but, as several evidence-based studies show, can also be an important factor in human nutrition and integrative medicine. Since the author is primarily concerned with conveying "miracle medicine facts" to the reader in a concise form, the scientific aspects have unfortunately been somewhat neglected. The book is primarily aimed at nutritionists and (the predominantly young) consumers of food supplements and calls for a new perspective away from the mainstream and a more critical look at the promises made in the marketing of superfood products.

Authors:Indira Riastiwi, Apriliana Dyah Prawestri, Ridwan Ridwan, I Putu Gede P. Damayanto Pages: 67 - 74 Abstract: Rapid decline in seed viability of Moringa oleifera Lam. due to storage severely reduces its capability to germinate. This study aimed to evaluate the viability of moringa seeds stored at various temperatures through seed germination on a selected medium and provide insights into its conservation in seed banks. The research consisted of two experiments. (1) Optimization of moringa seed germination using different media: A) sand 100%; B) mixed sand, soil, manure, rice husk charcoal (1:1:1:1); C) mixed sand, soil, and manure (1:1:1); D) mixed soil, manure, rice husk charcoal (2:1:1); and E) soil 100%. (2) Determination of moringa seed viability stored at various temperatures (-35, 5, 20, and 25 °C) every three months for 24 months. The information on the moringa seed banks was compiled via a literature review. Germination variables (percentage, rate, time, and index) were observed and recorded. The best germination medium for moringa seeds was medium B. Storage temperature at 5 °C was the most suitable temperature to maintain viability, indicated by the highest germination percentage, rate, and index, and the shortest germination time of only 6 days. There are moringa seed collections of 11 seed banks published online. PubDate: 2023-06-30 DOI: 10.5073/JABFQ.2023.096.008 Issue No:Vol. 96 (2023)
Authors:Yasin Ozdemir Pages: 81 - 87 Abstract: In this study some important physical, chemical and sensorial dried walnut characteristics of four varieties (‘Chandler’, ‘Fernor’, ’Yalova 3’ and ‘Şebin’) and five promising variety candidates (‘Giresun-7’, ‘İstanbul-2’, ‘144-84’, ‘Antalya-7’, ‘74-C’) were investigated. These findings were the first comprehensive report on the walnut properties of the above-mentioned candidates. ‘Antalya-7’ and ‘Giresun-7’ showed attractive fruit characteristics such as high whole kernel separation from shell and easy shell cracking. ‘Antalya-7’ attracts attention with fatty acids composition and appearance and taste scores. On the other hand, for ‘Giresun-7’, smooth shell surface, thin shell, high kernel ratio and high whole kernel separation from shell were determined as positive features. The polyunsaturated fatty acids content order of variety candidates was determined as 'Istanbul-2' > 'Antalya-7' > '144/84' > 'Giresun-7' > '74-C' (from high to low). The results of this study were used with agricultural project results for selection step of this breeding. The name of Giresun-7 was changed to 'Forest 77' and an application was made for variety registration. Its registration has been approved as a new variety by the Certification Center.

Authors:Yusuf Ersalı, Ibrahim Selcuk Kuru , Ibrahim Sevimli Pages: 94 - 99 Abstract: Sex identification in Pistacia species is economically important for pistachio producers because their long juvenile period delays crop production and gains. Since there is no easy method to identify sex during the juvenile period of this plant, morphological and physiological methods are expected to help in sex identification at the juvenile stage of Pistacia vera L. cv. Siirt (siirt pistachio) to determine potential differences in the sex of siirt pistachio trees and saplings. In the present study, the physiological and morphological differences were compared between female and male trees. Sixteen saplings were grown in the same field and environmental conditions. We measured GSH, GSSG, GR enzyme activity, total soluble sugar and protein, proline, MDA, chlorophyll-a, chlorophyll-b, carotenoid, pH values, and stomatal density of the leaf samples randomly selected from the sixteen saplings, and five male and five female trees. While the average GSH, GSSG, and GR activity of male trees was 2.45, 0.66, and 9.72, respectively, it was 5.94, 1.54, and 5.53 in female trees. The stomatal density of female and male trees and saplings was determined as 8.33-12.33, 15.00-23.66, and 9.66-24.00, respectively.
