As a result of the increasing availability of a greater variety of foods and a growing awareness of our nutritional requirements, as well as our interest in experimenting with new foods, we are now confronted by a vast array of products that we must learn how to distinguish between and use. The Visual Food Encyclopedia is designed to help the reader (both the novice and the experienced cook) find clear and precise information about a particu- lar food item as quickly as possible. Above all, it is a practical guide and refer- ence tool that provides inquisitive readers with the opportunity to discover new products or new ways to use familiar products. Although this encyclopedia includes some recipes, it is not a cook book, but rather a summary of everything that is known about food. It contains practical information about the origin, description, purchasing, preparation, uses, cook- ing methods, storage and nutritional value of foods. The information is arranged on dynamic, well-designed pages featuring clearly visible headings. The Visual Food Encyclopedia provides the reader with complete information about foods as diverse as meat, spices, vegetables, and fish, in a single volume. It is an invaluable guide that will help readers make well-informed choices, and sort through the overwhelming amount of information now available about food and nutrition. An integral part of the encyclopedia, the illustrations are instructive as well as attractive. They allow the reader to identify and distinguish between products at a glance. State-of-the-art, exceptionally precise photographs and/or illustra- tions reveal every detail of the item in question and help eliminate any linger- ing doubts. The images complement the descriptions, and help the reader dis- tinguish between varieties and species. This reference guide is the result of three years of effort by a large team of writers, researchers, editors, illustrators and designers. It contains entries on over 1,000 different foods, as well as more than 1,300 illustrations, pho- tographs and recipes. Divided into topics and subtopics, the encyclopedia also includes a table of contents, a detailed index and a glossary of specialized terms to help the reader access information as quickly as possible. Whether you want to improve your eating habits, enhance your knowledge of V food, verify the nutritional value of a product or just delight in the amazing diversity of foods described in the book, The Visual Food Encyclopedia will be a pleasure to consult and a feast for your eyes.

Serving ideas: what to do with Under the influence of Louis XIV, asparagus was rediscovered in the 18th century, unusual food, and new ways of and since then several new varieties have been developed. Today the principal producers of asparagus are the United States, Europe, Mexico, and Taiwan. using familiar food. Asparagus is actually a young edible shoot, commonly called a “spear”; the spear rises from an underground stem called a “crown,” which is capable of producing spears for 15 to 20 years. Most asparagus is harvested in spring, when it is 6 to 8 inches high and has tender, fleshy spears and tight, compact heads. Once they reach maturity, the asparagus stalks become woody and fernlike foliage grows from the heads, making them inedible. Although grown on quite a large scale and in many countries, asparagus is available in abundance only from March to late June. There are over 300 varieties of asparagus, only 20 of which are edible. They are divided into three main categories: • Green asparagus. This is the most common type of asparagus. It is harvested at a height You can select fresh produce with of about 8 inches. • White asparagus.

    Imported food risk statement Hijiki seaweed and inorganic arsenic Commodity: Hijiki seaweed Alternative names used for Hijiki include: Sargassum fusiforme (formerly Hizikia fusiforme, Hizikia fusiformis, Crystophyllum fusiforme, Turbinaria fusiformis), Hizikia, Hiziki, Cystophyllum fusiforme, deer-tail grass, sheep- nest grass, chiau tsai, gulfweed, gulf weed ,hai ti tun, hai toe din, hai tsao, hai tso, hai zao, Hijiki, me-hijiki, mehijiki, hijaki, naga-hijiki, hoi tsou, nongmichae. Analyte: Inorganic arsenic Recommendation and rationale Is inorganic arsenic in Hijiki seaweed a medium or high risk to public health? Yes No Uncertain, further scientific assessment required Rationale: Inorganic arsenic is genotoxic and is known to be carcinogenic in humans. Acute toxicity can result from high dietary exposure to inorganic arsenic. General description Nature of the analyte: Arsenic is a metalloid that occurs in inorganic and organic forms. It is routinely found in the environment as a result of natural occurrence and anthropogenic (human) activity (WHO 2011a). While individuals are often exposed to organic and inorganic arsenic through the diet, it is the inorganic species (which include arsenate V and arsenite III) that are more toxic to humans. Only inorganic arsenic is known to be carcinogenic in humans (WHO 2011a). Inorganic arsenic contamination of groundwater is common in certain parts of the world. Dietary exposure to inorganic arsenic occurs predominantly from groundwater derived drinking-water, groundwater used in cooking and commonly consumed foods such as rice and other cereal grains and their flours (EFSA 2009; WHO 2011a; WHO 2011b). However fruits and vegetables have also been found to contain levels of inorganic arsenic in the range of parts per billion (FSA 2012).

  • Edible Seaweed from Wikipedia, the Free Encyclopedia
    Edible seaweed From Wikipedia, the free encyclopedia Edible seaweed are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber.[1] They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food A dish of pickled spicy seaweed additives.[2] The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while some others can have a laxative and electrolyte-balancing effect.[3] The dish often served in western Chinese restaurants as 'Crispy Seaweed' is not seaweed but cabbage that has been dried and then fried.[4] Contents 1 Distribution 2 Nutrition and uses 3 Common edible seaweeds 3.1 Red algae (Rhodophyta) 3.2 Green algae 3.3 Brown algae (Phaeophyceae) 3.3.1 Kelp (Laminariales) 3.3.2 Fucales 3.3.3 Ectocarpales 4 See also 5 References 6 External links Distribution Seaweeds are used extensively as food in coastal cuisines around the world. Seaweed has been a part of diets in China, Japan, and Korea since prehistoric times.[5] Seaweed is also consumed in many traditional European societies, in Iceland and western Norway, the Atlantic coast of France, northern and western Ireland, Wales and some coastal parts of South West England,[6] as well as Nova Scotia and Newfoundland.

  • The Valorisation of Sargassum from Beach Inundations
    Journal of Marine Science and Engineering Review Golden Tides: Problem or Golden Opportunity? The Valorisation of Sargassum from Beach Inundations John J. Milledge * and Patricia J. Harvey Algae Biotechnology Research Group, School of Science, University of Greenwich, Central Avenue, Chatham Maritime, Kent ME4 4TB, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-0208-331-8871 Academic Editor: Magnus Wahlberg Received: 12 August 2016; Accepted: 7 September 2016; Published: 13 September 2016 Abstract: In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper reviews the potential uses and obstacles for exploitation of pelagic Sargassum. Although Sargassum has considerable potential as a source of biochemicals, feed, food, fertiliser, and fuel, variable and undefined composition together with the possible presence of marine pollutants may make golden tides unsuitable for food, nutraceuticals, and pharmaceuticals and limit their use in feed and fertilisers. Discontinuous and unreliable supply of Sargassum also presents considerable challenges. Low-cost methods of preservation such as solar drying and ensiling may address the problem of discontinuity. The use of processes that can handle a variety of biological and waste feedstocks in addition to Sargassum is a solution to unreliable supply, and anaerobic digestion for the production of biogas is one such process.

The toxicity of arsenic compounds is known to be related to their chemical speciation, and inorganic arsenic (iAs) is more detrimental than other species. Due to the different toxicities of the various chemical forms, speciation analysis is important for evaluating arsenic exposure. In this study, total arsenic (tAs) and six arsenic species (arsenite, arsenate, monomethylarsonic acid, dimethylarsinic acid, arsenobetaine, and arsenocholine) were analyzed in 180 seaweed samples. Although there were differences between seaweed species, the concentration of tAs was detected at levels ranging from 1 to 100 µg/g, and the distribution of six arsenic species differed depending on the seaweed species. No correlation between the concentration of iAs and tAs was found in most seaweed species. Through statistical clustering, hijiki and gulfweed were seen to be the seaweeds with the highest ratios of iAs to tAs.

  • Soy-Simmered HIJIKI
    è è ひじきの煮付け Hijiki No Nitsuké Soy-Braised Hijiki with Carrots and/or Fried Tōfu Hijiki No Nitsuké is especially popular on cafeteria menus and packed into many a child’s lunchbox. This dish combines the bounty of the field – carrots and/or soy in the form of fried tōfu – with the bounty of the ocean – hijiki, a calcium and iron rich sea vegetable. This surf-and-turf notion of balancing the source of foodstuffs in menu planning is typical of Japan’s indigenous food culture, washoku. Hijiki no Nimono can be served on its own as a side dish or tossed into rice; it can also get dressed in a thick, creamy tōfu sauce called shira aé. 4-6 portions 1/4 to 1/3 cup dried hijiki (black sea vegetable, preferably mé hijiki, the ‘buds’); see SPECIALNOTE 1 teaspoon vegetable oil (preferably aromatic sesame oil) 1 slice fried tōfu (abura agé), about 7 ounces, blanched, drained and thinly sliced 1 tablespoon saké 1 and 1/4 cups Dashi (Standard Sea Stock); archived at Kitchen Culture https://tasteofculture.com/wp-content/uploads/2020/08/Standard-Sea-Stock-Smoky-Sea- Stock.pdf 1 tablespoon sugar 1 carrot, peeled and cut into julienne sticks, about 3/4 cup 2 to 3 tablespoons regular soy sauce (shōyu) 1 tablespoon white sesame, freshly toasted Soak the hijiki in warm water to cover for 10-20 minutes.

    J. Jpn. Bot. 91: 33–40 (2016) Sargassum fusiforme (Fucales, Phaeophyceae) Has No Characteristic Stem in the Genus Sargassum a, b a Hiromori SHIMABUKURO *, Toshinobu TERAWAKI and Goro YOSHIDA aNational Research Institute of Fisheries and Environment of Inland Sea, Fisheries Research Agency, 2-17-5 Maruishi, Hatsukaichi, Hiroshima, 739-0452 JAPAN; bNational Research Institute of Fisheries Engineering, Fisheries Research Agency, 7620-7, Hasaki, Kamisu, Ibaraki, 314-0408 JAPAN *Corresponding author: [email protected] (Accepted on July 1, 2015) Sargassum fusiforme is a very useful product for fisheries and is well known in Japan; however there are few detailed reports about its morphological characteristics. This species was initially assigned to the genus Cystophyllum and was subsequently categorized in the genus Turbinaria because of a lack of distinction between its leaves and vesicles. Recently, this species was categorized in the genus Sargassum based on the results of molecular studies; however, a debate has arisen between researchers who propose that the species belongs to the genus Sargassum and those in Japan who maintain that it belongs to the genus Hizikia. This difference in opinion is caused by a large morphological variation in the leaves among the different latitudes in which the species grows. The leaves of S. fusiforme growing in temperate regions are narrow, while those growing in low-latitude regions are lanceolate with dentate margins. The branches of Sargassum spp. generally arise from the stems on the holdfast; however, the branches of S. fusiforme arise directly from the holdfast. The biennial S. fusiforme has no stem, which is a characteristic of the genus Sargassum.

  • ENCYCLOPEDIA of FOODS Part II
    ENCYCLOPEDIA OF FOODS Part II art I of this book reviewed the relationship of diet to health and provided recommenda- Ptions for choosing foods and planning diets that contribute to health. The healthiest diets are based on a variety of plant foods—whole grains, vegetables, fruits, legumes, and nuts. Animal products and added fats and oils, sugars, and other sweeteners are best consumed in small quantities. The Food Guide Pyramid reviewed earlier in this book graphically emphasizes the proportions of these foods in the daily diet. Accordingly, we have arranged this section with priority given to grains, fruits, and vegetables—those items that should predominate at every meal and that most people need to consume in greater quantities. Animal products—meat and other high-protein foods and dairy foods—are also discussed. However, these are the foods that should make up relatively smaller parts of our diets. Part II introduces you to many foods from which you can choose and provides you with knowledge about the nutrients these foods have to offer. In addition, we provide informa- tion about the sources of the foods you purchase and eat—the individual plants and animals, how they are processed to the products that appear on store shelves, and some of the history of these foods in our diet. Before we introduce the foods themselves, we want to explain the arrangement and presentation of food items in these sections. Because this book is written for a North American audience, we have included food products that are available to most North Americans. Within the sections on Fruits and Vegetables, we have listed items by their common names in alphabetical order; when a food has more than one common name, the index should help in locating the item.

Since DMA is considered to be carcinogenic in rodents, it is necessary to accurately measure the contents of AsSugs as well as iAs for the risk assessment of seaweed consumption. Seven commercially available dried-hijiki products and two raw hijiki products were analyzed. Total-As was measured by inductively coupled plasma mass spectrometry (ICP-MS) with the Dynamic Reaction Cell (DRC) mode after acid-digestion. After water-extraction, AsSugs were detected by HPLC-MS/MS with multiple reaction monitoring in the positive ion mode and speciation analysis of arsenics was performed by HPLC-ICP-MS. The ranges of total-As obtained by acid digestion (A-TAs) in nine hijiki samples were 37.1–118.6 µg As/g dry weight (dw), and those of water extracted total-As (W-TAs) were 18.4–81.0 µg As/g dw.

Sargassum fusiforme (hijiki) is a popular edible seaweed in some Asian countries. However, it has been shown to have high concentrations of arsenic, mainly the more toxic inorganic arsenic. In this study, we determined the concentration, species, distribution, and absorption kinetics of arsenic (As), and the influence of different exogenous substances on its absorption. Arsenic content in the mature stage of hijiki reached up to 84.37 mg/kg dry weight. Inorganic arsenic (iAs) accounted for 68% of the total arsenic, while Arsenate (As (Ⅴ)) accounted for more than 50% of total inorganic arsenic. The contents of arsenic in different hijiki organs decreased in the following order rhizoid > stem > leaf > airbag. Subcellular distribution of arsenic in untreated hijiki decreased in the order: cell walls > cell organelles > cytoplasm. In hijiki, arsenate had a higher absorption rate than arsenite (As (III)), with Vmax and km about 2 times and 3 times those of As (III), respectively. The absorption of As (V) was inhibited by phosphorus, but was not affected by glycerol.
