Improper levels or excess of iodine may present a greater risk to health, for this reason, this paper aims to assess the iodine content present in salt and estimate the iodine concentration in school meals in a Brazilian northeast region.

Six samples of different salt brands sold in the city of Lagarto, Sergipe, Brazil were gathered for analyzing iodate concentration. The amounts of salt added to meals of four schools in the city and the weight of the provided meals were recorded during two consecutive days of gathering, thus obtaining data to estimate the iodine content of these meals. The rest of the meals and the nutritional composition of school meals were analyzed. A questionnaire for participants on the perception of salt was applied. For data analysis, α = 5% was used.

The iodine concentration in all salt samples followed legislation (15 to 45 mg of iodine/kg of salt), with the average of iodine ranged between 26.5 ± 1.29 and 33.9 ± 2.49 mg/kg (p < 0.001). The estimated iodine content in consumed school meals was 0.025 mg (25 µg), in meals of schools A and C, it was 0.03 ± 0.02 mg, and to schools B and D, it was 0.02 ± 0.01 mg (p < 0.001). Percentages of rest of the meals greater than 10% were found and the assessed food preparation showed low caloric and nutritional values.

The iodine content is in accordance with the salt iodization policy in Brazil, and that the average iodine estimate in school meals was considered adequate for this population.

Three events of significance to this country took place in 1899 – the British Food Journal was launched, Australia retained the Ashes, and the Boer War hostilities commenced. If challenged on the order of their importance, cricketers and Empire‐builders may be excused their preference. However, looking at it purely from the standpoint of pro bono publico, the dispassionate observer must surely opt for the birth of a certain publication as being ultimately the most beneficial of the three.

Seaweeds are gaining broader interest in Western societies through their use in product development and the health-food industry. High nutritional value, low carbon footprint and sustainability are key drivers for seaweed uptake in Europe; yet high iodine intake from seaweed remains a concern. This study seeks to identify seaweed food products available on the UK retail market between 2018 and 2021 and assess their safety in the context of iodine exposure.

Here, a market survey (n = 37–40 retailers) was conducted in three annual waves to evaluate seaweed food product availability in the UK. The iodine dose of products was estimated based on a comprehensive literature review of seaweed iodine content.

This study shows a young, dynamic market with 2.3-fold increase in seaweed food product availability since the last available published data (2015). Specific iodine content labelling remains uncommon, and median iodine doses in a single serving of food exceeded 400 µg in all years. Some products, especially seaweed supplements, provide iodine doses above the tolerable upper limit and upper level of tolerance.

This study presents the most contemporary and comprehensive overview of the market for seaweed food products in the UK. With increasing popularisation of seaweed as a food, this study highlights the need for improved dialogue amongst producers, retailers, legislators and public health specialists to address the risk of iodine excess, and the concurrent scope for processing methods to reduce the iodine content in seaweeds.

In this number of the journal we present for our readers' consumption a most varied fare—animal, vegegetable and mineral. We have sand in the parsley, rodent droppings in the stuffing, added water in the milk and vinegar, to say nothing of the malignant prospects of radio iodine in milk and radiostrontium in flour and other commodities. Iron filings in peanut butter, beetles in the bilberries, glass and nails added to the morning rolls for spite, “pinhead” oatmeal with maggots, mites and grubs and serious doubts as to whether it should have found its way to the stomachs of humans or the crops of chickens, settled albeit by a Scot—and who should know better?—that it was used in fact for making porridge! Potted shrimps and meat containing preservatives that they shouldn't; double cream and fruit drinks that are not quite, but tomato piquant that apparently is. At this season of the year we surely have here an excellent feast for the humour of “Punch” and abundant material to stir the imagination of writers of doggerel verse!

This new measure of consumer law of some forty‐odd sections, a short Act by present standards but as far‐reaching as any legislation since the war, establishes a code of conduct in commerce and trade which few will be able to ignore, from the manufacturer down to the counter‐hand. Operative from November 30th of this year, traders will require to urgently consider their sales practices, advertising, labelling and their trade descriptions; sales staff will need to be instructed in their new responsibilities. The new law is not just for consumer‐retailer transactions, but extends to trade between different branches of all trades, so that a retailer will be protected against misleading descriptions and misrepresentations by a manufacturer and the latter against misdescriptions of ingredients or components.

The purpose of this paper is to study the resilience and elastic properties of short pastry with the meals of soy, sunflower and milk thistle.

Recent studies in the emerging food technologies of short pastry with use of meals were considered. Their focus on the improvement of the functional peculiarities of short pastry and benefits for people were the defining characteristics of the studies.

Model food compositions have been developed from soybean meal, sunflower meal and milk thistle for adding them to semi-finished short pastry products. The technology of short pastry confectionery made from short pastry with oilseed meal has been scientifically substantiated and developed. The chemical composition of shortbread cookies with the use of oilseed meal was calculated. The developed technology increased protein content by 2.5 times, cellulose content – by six times, significantly increased mineralization in the developed confectionery products. The content of calcium increased by 172.9 mg, selenium – by 13.06 mcg, iodine – by 2.76 mcg and vitamin E by 2.4 mg.

The developed technology of short pastry with a model composition of the meal can be used in practice. The use of a meal composition is a promising direction to improve the brittleness of short pastry products. The developed pastry products made from short pastry with added meal can be introduced into catering establishments as functional products with improved biological value.

Developed pastry products can be used as functional products with improved biological value, which is important for people’s health and has positive effects on the human body.

The use of meals of soy, sunflower and milk thistle in short pastry increases its nutritional and biological value, which improves the impact on the human body. The developed pastry products can be introduced as functional products with improved biological value, which is important for the improvement of people’s health in different countries of the world.

The season of mass holiday treks for the multitude is upon us. Since the new year, the newspapers and magazines have carried pages of advertisements and travelogues and each year the holiday horizon is pushed farther and farther away; now it includes Bulgaria, Rumania, remote islands, countries beyond the Iron Curtain and even China. Tourism has become big business. In the U.K., with a million or more visitors, it is considered a major industry. But what of Italy with eight million visitors, Spain running her very close, France with a mere two millions, Switzerland, Austria and other countries in between? All these countries may be geared to meet big invasions of foreign people during the tourist season, but understandably there are inevitable health risks and the most important of these are undoubtedly water‐ and food‐borne infections. Dietary disturbances due to the change of food and drink, especially of wine, by people who are unaccustomed to it, are of a transitory nature, and remedied by simple measures which include abstinence from rich and indigestible foods.

We are growing accustomed to shock tactics of the US Administration in dealing with toxic residues in food or additives which are a hazard to man, as well as the daily press infusing sensation, even melodrama, into them, but the recent action of the FDA in calling in from the food market several million cans of tuna and other deep sea fish because of the presence of mercury has had the worthwhile effect of drawing world attention to the growing menace of environmental pollution. The level of mercury in the fish is immaterial; it should never have been there at all, but it stresses the importance of the food chain in the danger to man and animal life generally, including fish beneath the sea. Without underestimating risks of pollution in the atmosphere from nuclear fission products, from particulate matter carried in the air by inhalation or even skin absorption, food and drink, which includes aqua naturale would seem to be the greatest danger to life. What these recent events illustrate in a dramatic manner, however, is the extent of pollution.

Scientists have often been accused of a desire to reduce the human diet to a pill or powder form “to be taken daily with water at meal times.” Whatever truth there might be in the allegation, it is an actual fact that more and more foods are being proved suitable for preservation in dried form. This is partially a logical development of the processes of food preservation, which are largely the concentration of food products for convenience in transport and storage, and partially the results of special war‐time demands. The need for concentrated nourishment is never greater than under conditions of war stress, and the present serious pressure upon Allied shipping facilities has further tended to increase the need for foods that occupy the least possible space. On the average, one pound of fully dehydrated food is the equivalent of fifteen pounds of the same product in its original form. Thirty dozen eggs in the shell, packed and created for shipment, occupy 2¼ cubic feet; dried, the same number take slightly more than one‐half cubic foot. The saving in ships and cargo space is obvious. While the problem of shipping space has been a major factor in the stimulated interest in dehydration, other elements in the existing situation have also had their influence. In Great Britain, under constant threat of invasion, it has been essential to build up reserve stocks of food throughout the country, often under storage conditions that are far from ideal. The serious shortage of tin has restricted the use of ordinary canning methods to foods which cannot, at the present stage of research, be preserved in any other form. A further stimulus has been given by the necessity of providing concentrated foods for paratroops and commando units, which must be entirely self‐sufficient when in action. Special rations are prepared which provide meals for two or three days, yet weigh only a few pounds. Drying is the oldest known form of food preservation, in fact it may be termed the natural method of preservation. Nature herself uses it. On the average, seeds, grains and nuts contain less than 10 per cent. of moisture, regardless of the amount which may be present at earlier stages of growth. The very existence of vegetable life from year to year is in the final analysis dependent upon this lack of moisture which inhibits the growth of bacteria and moulds. Perhaps by some accident, perhaps by imitation of the natural process, man early began to preserve food by drying, either in the sun or by artificial heat. Robinson Crusoe's raisins and the dried apples of our pioneer ancestors leap at once to the mind. Dried fruits and fish, jerked and smoked meats are all preserved by the removal of some part of their original water content. Sometimes this is the sole process, sometimes it is combined with other methods, as salting or pickling. In recent years, however, the preservation of foods by canning, refrigeration, and latterly by quick‐freezing has largely replaced the earlier method. Natural or artificial drying methods have in the past permitted the storage of food and the retention of a part of its nutritive value at the expense of flavour and colour. Everyone knows the difference between the flavour and texture of sweet corn in the milky stage and that which has ripened further, i.e., begun to dry out. In the case of such products we have largely come to prefer the dried flavour, even where we can know the so‐called fresh flavour. Some artificially dried or semi‐dried foods have, in fact, retained their place in the modern diet in direct competition with the fresh form, not as substitutes, but as independent food products in their own right. Such fruits as dates, figs, prunes and raisins are perhaps the best examples. No one expects raisins to take the place of grapes or prunes to have the same flavour as plums. These so‐called dried fruits are, however, really only semi‐hydrated. They retain from 20 to 25 per cent. of their moisture; only enough has been removed to ensure their keeping qualities. While they are a concentrated product, the process has not been carried to the point of complete transformation into the solid form. Jerked or dried meat and such products as pemmican are also among the oldest forms of preserved food, and jerked beef is still extensively produced in many countries. A more generally known form of meat product is meat extract. There are a number of famous brands, available either as a thick syrupy liquid or in a solid cube. The keeping property is implicit in its low water content, usually about 15 per cent. These extracts are prepared by removal of the fat and albumen, the addition of salt and evaporation in vacuum. One pound is ordinarily obtained from twenty‐five pounds of lean meat. Packing companies in the United States report that experimental methods of producing a true dehydrated meat, one which can be restored to its normal character, have been successful, at least in regard to beef. Pork is apparently too fat for such treatment. If the process works on a commercial scale as successfully as in the experiments, additional savings in shipping space will be realised. It is estimated that one ship could carry as much meat as ten cargo vessels were able to transport during the last war. Among other concentrated foods that go back to antiquity are the milk products, butter and cheese. These belong to the class which has little relation in either flavour or texture to the original from which they are made. Cheese is a product of fermentation as well as drying, while butter is additionally protected by salt and by refrigeration in storage and transport. Thus, while the removal of water is an important step in their manufacture, they cannot be considered dried foods. Recent reports from New Zealand indicate that butter is now entering this category. As a result of research which antedates the war, the New Zealand Dairy Research Institute has perfected a method of dehydrating butter. The British Government has contracted to purchase 20,000 tons during 1942 and 1943. A trial shipment of 400 tons was made last year and was well received. According to a report from the Canadian Trade Commissioner in New Zealand, the process was developed originally in order to reach markets not served by refrigerator ships. The dislocation of the shipping facilities between New Zealand and Great Britain has eliminated the usual means of sending butter. The new product, however, can be shipped as general cargo on any ship that may be available. The dried butterfat can be used directly by industrial food manufacturers and its conversion into table butter is simply adding a matter of water and salt. Not only will it serve a valuable war‐time purpose of providing Great Britain with needed fats, but it will also relieve the position of dairy farmers in New Zealand. After the war it is considered possible that the original purpose of marketing in countries without refrigerator service may continue to absorb available supplies.

Sargassum fusiforme is a popular edible seaweed in coastal cities of China that contains diverse nutrients including iodine. Cooking is an effective way to improve food safety, but it can alter both the contents of elements along with speciation and bioavailability. Three common cooking methods, the soaking, steaming and boiling, were evaluated for their effects on the protein structures, protein digestibility, iodine content and iodine bioavailability of S. fusiforme.

Fourier transform infrared spectroscopy was used to study the structural changes of protein, and an in vitro digestion/Caco-2 cell culture system was used to evaluate the digestibility of protein, bioaccessibility and bioavailability of iodine.

Boiling and steaming altered the protein secondary structure demonstrated by increased a-helix and random coil and decreased β-sheet, which improved the in vitro protein digestibility. Iodine content was reduced by cooking, with the highest loss observed after boiling, followed by soaking and steaming, while it was found that both bioaccessibility and cellular uptake of iodine were significantly elevated by boiling and steaming using an in vitro digestion/Caco-2 cell culture system. The presence of ascorbic acid, citric acid or tyrosine was beneficial for the iodine absorption, while oxalic acid and phytic acid hindered the iodine bioavailability.

The present finding suggested that cooking was conducive to the digestion and absorption of iodine in S. fusiforme. In addition, different dietary factors could have a certain impact on the absorption of iodine. Results of the study are essential for improving the application value of S. fusiforme to ensure reasonable consumption of seaweeds.
