A high somatic cell count (SCC) impacts dairy quality to a large extent. The goal of this work was to investigate differences in goat milk composition and technological parameters according to SCC cut-off (600, 700, 800, and 1000.103/mL). Thirty-four individual milk samples of White Shorthair goats in a similar stage of lactation were investigated. The first differences in milk quality appeared already at SCC cut-off of 600.103/mL (5.58 LSCS-linear somatic cell score), yet the most striking differences were found for SCC over 1000.103/mL (6.32 LSCS), which was expressed by lowering heat stability (126 vs. 217 s, p = 0.034), increasing protein (3.41 vs. 3.04%, p = 0.009), casein (2.80 vs. 2.44%, p = 0.034) and chloride (164 vs. 147 mg/100 mL, p = 0.004) levels, as well as non-fat dry matter (8.79 vs. 8.45%, p = 0.045). It has been shown that low levels of Staphylococcus spp. bacteria (120–1600 CFU/mL) in the mammary gland correlated with decreased lactose content (4.60 vs. 4.47 g/100 g, p = 0.022). Since our results indicate that even low SCC values may significantly affect the technological properties of goat milk, SCC should therefore be routinely screened and reported to dairy manufacturers to assure the consumer of high end-product quality.

The cultivation of sweet chestnuts in Slovakia has a century-year-old tradition. However, just a few research publications provide more comprehensive information about the chestnuts’ chemical composition of different varieties in individual growing areas. Sweet chestnuts contain various nutrients, of which carbohydrates are very important for assessing their commercial quality. Simple carbohydrates are mainly represented by glucose, fructose, sucrose, and maltose. The content of glucose was 0.178–3.152, fructose 0.271–3.170, sucrose 9.355–29.890, and maltose 0.171–1.584 g/100 g DW in chestnut samples from 27 sampling points, which are part of Slovakia’s four largest growing areas of sweet chestnuts. Carbohydrate contents were determined by the high-performance liquid chromatography (HPLC-RI) method. There are statistically proven differences in the content of individual carbohydrates depending on the sampling area of chestnuts. Potassium has a significant presence in sweet chestnuts as a mineral substance. Its content was determined in the 377–789 mg/100 g DW range. The content of sodium (calcium, magnesium, and phosphorus) was 0.65–6.90 (26.9–103, 58.7–101, and 96.5–179) mg/100 g DW. The contents of mineral substances were determined by the AAS method. The content of carbohydrates and mineral substances is mainly influenced by variety and age.

The effect of insect powder addition on the acrylamide formation in leavened and unleavened wheat bread and on the content of its main precursors in raw material was investigated. The samples under study were prepared form wholemeal wheat flour supplemented with 5, 8, and 12% of field cricket or yellow mealworm powder. The addition of both insects increased the content of reducing sugars and free amino acids, except for asparagine, the limiting factor of acrylamide formation in cereal products, which was lower in the samples with the greatest cricket and mealworm supplementation than in the control wheat flour (242.4 and 177.9 vs 249.6 mg/kg). For unleavened bread, an increase in acrylamide was recorded with the highest share of cricket and mealworm compared to the control (up to 14.03 and 29.52 vs 11.02 μg/kg). Conversely, for leavened bread, the variants most supplemented with cricket and mealworm exhibited the lowest acrylamide content relative to the control (64.84 and 68.78 vs 82.47 μg/kg). It is indicated by the results that the supplementation of bakery products with insects enriches their nutritional value and does not pose a risk of increased acrylamide intake by consumers.
