Abstract Numerous variations exist for determining the acidity of fats and oils by titration. A Youden ruggedness test was performed, using extreme conditions existing in the methods, endorsed by various international organizations: aqueous and alcoholic standard alkali, 5 or 56 g sample, 50 or 150 ml alcohol or alcohol-ether solvent, titration at room temperature or 60°C with 2 ml or 8 drops of phenolphthalein indicator, to the first color change or to a pink persisting for 60 sec. The titration method was found to be extremely rugged at the 1 % oleic acid level with none of the variables influencing the result. At the 0.15% level, only the sample size affected the result.

Freshwater fish represent half of all fish species and are the most threatened vertebrate group. Given their considerable passion and knowledge, aquarium hobbyists can play a vital role in their conservation. CARES is made up of many organizations, whose purpose is to encourage aquarium hobbyists to devote tank space to the most endangered and overlooked freshwater fish to ensure their survival. We found the CARES priority list contains nearly six hundred species from twenty families and two dozen extinct-in-the-wild species. The major families were typically those with the largest hobbyist affiliations such as killifish, livebearers, and cichlids, the latter containing half of CARES species. CARES included every IUCN threatened species of Pseudomugilidae and Valenciidae, but only one percent of threatened Characidae, Cobitidae, and Gobiidae species. No Loricariidae in CARES were in the IUCN red list as they have not been scientifically described. Tanzania and Mexico contained the largest amount of species, with the latter containing the most endemics. Many species were classified differently than the IUCN, including a third of extinct-in-the-wild species classified as least concern by the IUCN. This vast disconnect exemplifies the importance of future collaboration and information exchange required between hobbyists, the scientific community, and conservation organizations.

The high fruit soluble sugar content in wild Lycopersicon species and their hybrids with cultivars depends on sucrose import during ripening rather than on sucrose metabolism

Soluble sugar content has been studied in relation to sucrose metabolism in the hexose-accumulating cultivated tomato Lycopersicon esculentum Mill, the wild relative species Lycopersicon cheesmanii Riley, in the sucrose-accumulating wild relative species Lycopersicon chmielewskii Rick, Kesicky, Fobes & Holle. and in two hexose-accumulating interspecific F1 hybrids (L. esculentum × L. cheesmanii; L. esculentum × L. chmielewskii), cultivated under two irrigation regimes (control: EC = 2.1 and saline: EC = 8.4 dS m–1). Under control conditions the total soluble sugar content (as hexose equivalents) in the ripe fruits of L. cheesmanii was 3-fold higher than in L. esculentum, while L. chmielewskii and both F1 hybrids contained twice as much as the cultivar. With the exception of L. esculentum × L. cheesmanii, salinity increased the sugar content by 1.3 (wild species) and 1.7 times (cultivar and L. esculentum × L. chmielewskii) with respect to control fruits. Wild germplasm or salinity provided two different mechanisms for the increases in fruit sugar content. The hexoses accumulated in ripe fruits were strongly influenced by those accumulated at the start of ripening, but the hydrolysed starch before start of ripening only partially explained the final hexose levels and especially the increase under salinity. The early cell wall acid invertase and the late neutral invertase activities appeared to be related to the amount of hexoses accumulated in ripe fruits. However, no metabolic parameter was positively related to the amount of sugar accumulated (including sucrose). The major differences between genotypes appeared in ripe fruits, in which up to 50% of the total amount of sugars accumulated in the wild species (mainly in L. cheesmanii) and hybrids cannot be explained by the sugars accumulated and the starch hydrolysed before the start of ripening stage. As a consequence, the higher fruit quality of the wild species compared with L. esculentum may depend more on the continuation of sucrose import during ripening than on osmotic or metabolic particularities such as the hexose / sucrose-accumulator character or specific enzyme activities.

Controlling the content of trace elements in human food is a major problem. Lack of them, as well as their excess, can seriously affect a person’s health. Commonly, people do not receive enough minerals they need. Though these minerals are found in products of both animal and plant origin, many ethnic groups have a significant preference for plant food, which is very often obtained from cereal plants. Not infrequently, though, these plants are poor in mineral elements, or a specific processing technology depletes a product of minerals. This article shows the content of such trace elements important for people as zinc, copper, cobalt, and nickel in the seeds and leaves of cultivated flax (L. usitatissimum) and its three wild perennial relatives (L. austriacum, L. hirsutum, and L. thracicum). We focus on flax, because, besides containing valuable trace elements, it is also a source of unsaturated fatty acids which are no less important for the human body. To date, there is but little information on the content of certain trace elements in the seeds of cultivated flax, and practically nothing is known about their content in its wild relatives, which are used mainly as decorative verdure. It has been established that the seeds contain 37.1-64.2 mg/kg of zinc, 5.3-9.3mg/kg of copper, 2.9-7.3mg/kg of nickel, and 1.4-3.3mg/kg of cobalt. In the leaves, these trace elements are present in far smaller amounts (1.1-4.3mg/kg). The highest in these trace elements is the wild species L. thracicum, and the lowest is L. austriacum. It has been found that in the plant material of cultivated flax, the ratio of the microelements under study was similar to that in the wild species. Zinc predominates in the flax seeds, but in the leaves, it exceeds other elements only insignificantly. Generally, both cultivated flax and its three wild relatives can be viewed as valuable and worthwhile sources of zinc, cobalt, copper, and nickel.
