Article Abstract
The aim of this study was to determine the effect of different temperatures of blanching and pre-drying used in the laboratory production of dried potato dice on the content of glycoalkaloids in red and blue fleshed potato varieties. Studied potatoes of coloured fleshed varieties were characterised by a low glycoalkaloids content at 5.47 mg 100 g(-1). The production of dehydrated potato dice influenced on the decrease in glycoalkaloids content in potato products. The majority of these compounds were removed during the peeling (70%) and blanching process (29%). Potato dice blanched at the highest temperature (85 °C) and pre-dried at 120 °C was characterised by the lowest quantity of glycoalkaloids content, whereas the highest content of these compounds was found in dice blanched potato at the lowest temperature (65 °C) and pre-dried at 120 °C. The blanching process much influenced on the decrease in glycoalkaloids content than pre-drying process.

One of the main challenges in the transition from animal to plant proteins is the presence of undesired non-volatile co-passengers in plant protein ingredients, including off-tastants. Despite this, data on the non-volatile composition of commercial plant protein concentrates and isolates is lacking. Therefore, our main aim was to systematically identify and quantify the semi-polar co-passengers present in commercial soy, pea, oat, potato, and almond protein isolates or concentrates.

Green tomatoes, a by-product of agro-food industry, are rich in the glycoalkaloid alpha-tomatine. This compound presents health benefits including anti-inflammatory and fungicide properties. Subcritical water extraction (SWE), a green and sustainable process, was used to obtain a tomatine-rich extract from fresh or frozen tomatoes.

Tomato (Solanum lycopersicum), an economically important crop rich in secondary metabolites, serves as a model organism for studying secondary metabolism. However, research into how non-coding RNAs (ncRNAs) regulate metabolite accumulation in tomato is limited. Here, we identified and characterized 418 microRNAs (miRNAs) in 3 tomato subgroups: Solanum pimpinellifolium, Solanum lycopersicum var.

Background: Steroidal glycoalkaloids (SGAs), derived from cholesterol, act as natural defenses against pathogens and pests. In cultivated potatoes, α-solanine and α-chaconine are the primary SGAs, distributed throughout the plant, with their biosynthesis mechanisms differing across various tissues. The variation in SGAs content between the cortex and perimedullary zone reflects tissue-specific metabolic regulation in potato tuber.
