Thermodynamics of moisture sorption in tobacco (Nicotiana tabacum L.) seeds

et al. 2020

In this study, the thermodynamic characteristics of tobacco seeds were investigated, based on experimental data from equilibrium moisture isotherms at desorption. An empirical exponential relationship was found for the decrease of the net isosteric heat and the differential entropy, based on the Clausius-Clapeyron equation, in response to the increase in moisture content; the values of the two parameters varied from 31.09 to 1.46 kJ.mol-1 and from 91.53 to 4.29 J.mol-1.K-1, respectively. The linear relationship between the enthalpy and the entropy in the moisture desoption of tobacco seeds supported the validity of the enthalpy-entropy theory. The value of Gibbs free energy was positive and the harmonic temperature (297.5 K) was lower than the isosteric temperature (339.6 K). The outcomes from the study provide for the deeper insight into the process of moisture desorption of tobacco seeds.

“…Seeds contain 30%-60% starch, 6%-11% protein, 4%-8% lipids and 8%-26% saponins (Baraldi et al, 2007;Čukanović et al, 2011;Duke & Ayensu, 1985;Lemajić, Savin, Ivanić, & Lalić, 1985), but these are variable between populations. Seeds from southern Bulgaria contained 81 ± 3 g/kg (SD) of oils, including relatively high levels of unsaponifiable compounds (57 ± 1 g/kg), sterols (12 ± 2 g/ kg), phospholipids (3 ± 0.1 g/kg) and tocopherols (627 ± 15 mg/kg) (Zlatanov, Antova, Angelova-Romova, & Teneva, 2012). The starch has a low amylose content (Hricovíniová & Babor, 1992).…”

Biological Flora of the British Isles:Aesculus hippocastanum

et al. 2019

View full text Add to dashboard Cite

This account presents information on all aspects of the biology of Aesculus hippocastanum L. (horse‐chestnut) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. Aesculus hippocastanum is a large deciduous tree native to the Balkan Peninsula. Native populations are small (<10,000 trees total) and apparently in decline, but the tree has been widely planted in gardens and streets across Europe and other temperate areas from the 17th century onwards. It was voted the UK's favourite tree in a 2017 poll. As a British neophyte, it is occasionally naturalised in open wooded habitats. Horse‐chestnut is renowned for the beauty of its large (up to 30 cm long), upright panicles of white flowers, and for the large seeds (up to 42 g each) used in the formerly common children's game of “conkers.” More recently, the triterpene glycosides, extractable from various plant parts but especially the seeds, have been widely used in medicine. In much of Europe, horse‐chestnut is affected by chestnut bleeding canker (caused by Pseudomonas syringae pv. aesculi), the horse‐chestnut leaf miner Cameraria ohridella and the leaf blotch fungus Guignardia aesculi. The canker is likely to lead to death of <10% individuals, but seeds of plants infested with the leaf miner are 40%–50% smaller, which may affect long‐term establishment in non‐planted areas.

“…Chestnut is a low-fat fruit [6,7] that is rich in minerals and vitamins [3], has high levels of moisture [7] and considerable amounts of fiber, and contains high levels of starch [3,7]. Moreover, chestnut contains phospholipids, tocopherols, and sterols and fatty acids, particularly linoleic [8]. Chestnuts are low in sodium and high in potassium, phosphorus, and magnesium [9].…”

“…Diets rich in PUFAs may also contribute to improve vascular and metabolic conditions like hypertension and type 2 diabetes, and to decrease the blood concentrations of cholesterol, in particular that of low-density lipoproteins (LDLs) [14]. Additionally, chestnut oil contains large amounts of phytosterols, particularly β-sitosterol, followed by stigmasterol [8], both of which may also contribute to reduce cholesterol levels and prevent diabetes [15,16]. Actually, chestnut has the highest levels of phytosterols when compared to other nuts (almonds, hazelnuts, walnuts, and peanuts) [5].…”

Dietary Supplementation with Chestnut (Castanea sativa) Reduces Abdominal Adiposity in FVB/n Mice: A Preliminary Study

et al. 2020

The production of chestnut (Castanea sativa Miller) is mostly concentrated in Europe. Chestnut is recognized by its high content of antioxidants and phytosterols. This work aimed to evaluate the effects of dietary chestnut consumption over physiological variables of FVB/n mice. Eighteen FVB/n male 7-month-old mice were randomly divided into three experimental groups (n = 6): 1 (control group) fed a standard diet; 2 fed a diet supplemented with 0.55% (w/w) chestnut; and 3 supplemented with 1.1% (w/w) chestnut. Body weight, water, and food intake were recorded weekly. Following 35 days of supplementation, the mice were sacrificed for the collection of biological samples. Chestnut supplementation at 1.1% reduced abdominal adipose tissue. Lower serum cholesterol was also observed in animals supplemented with chestnut. There were no significant differences concerning the incidence of histological lesions nor in biochemical markers of hepatic damage and oxidative stress. These results suggest that chestnut supplementation may contribute to regulate adipose tissue deposition.
