The present review of patent and scien- tific literature shows that carrageenan is a useful additive in the cheese production process. The gel-strength- ening properties of carrageenan are as a result of the fairly strong bonds it forms with casein macromolecules. Read More

Effects of unextruded and extruded cranberry pomace on selected metabolic parameters in high-fat diet fed rats.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):91-100

Institute of Human Nutrition and Dietetics, Poznań University of Life Sciences , Poland.

Background: The effects of un-extruded (UCP) and extruded cranberry pomace (ECP) on fecal fat excretion, liver index, lipid and carbohydrate metabolism, and inhibition of oxidative stress due to a high-fat diet (HFD) in rats were studied.

Methods: The Wistar rats for 8 weeks received one of the four diets: (1) control (modified the American Institute of Nutrition: AIN based diet containing 7% fat), (2) HFD (AIN based diet containing 30% fat), (3) HFD with 3% un-extruded (UCP) and (4) HFD with 3% (ECP).

Results: Both UCP and ECP significantly improved the plasma antioxidant capacity and decreased lipid per- oxidation in rats fed a HFD. Read More

The impact of lifestyle factors on age-related differences in hair trace element content in pregnant women in the third trimester.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):83-89

Department of Psychology of Personality, Tomsk State University, Russia.

Background: Trace elements play a significant role in the regulation of human reproduction, while advanced age may have a significant impact on trace element metabolism. The objective of the present study was to assess the impact of lifestyle factors on age-related differences in hair trace element content in pregnant women in the third trimester.

Methods: A total of 124 pregnant women aged 20–29 (n = 72) and 30–39 (n = 52) were ex- amined. Read More

Lactobacillus spp. belonging to the Casei group display a variety of adhesins.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):69-82

Department of Food Biotechnology and Microbiology, Poznań University of Life Sciences, Poland.

Background: n. Adhesion of bacteria from the genus Lactobacillus to the gastrointestinal epithelium is, to a considerable degree, dependent on the interactions between adhesins found on the surface of bacterial cells and elements found within the epithelium. A significant role in these interactions is played by bacterial pro teins exposed to the cell wall surface, which are capable of binding to molecules of substances comprising the extracellular matrix of the intestinal epithelium.

Identification and study of the behavior of S. aureus and S. epidermidis in fresh and frozen strawberries.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):27-35

Department of Commodity Science and Quality Management, Gdynia Maritime University, Poland.

Background: Methicillin-Resistant Staphylococcus aureus (MRSA), which is resistant to many antibiotics, creates a serious problem for human health if present in food. This study aimed to assess the quality of commercially-available fresh and frozen strawberries and to compare the behavior of staphylococci in these fruits as affected by the temperature of freezing.

Methods: The research material included different species of fresh strawberries and strawberries frozen with the fluidization method to –40°C and packaged in an industrial environment. Read More

Physico-chemical and thermal properties of chicken myofibrillar protein concentrate (CMPC) mixed with barley bran flour during frozen storage.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):19-26

Department of Food Technology, University of Osijek, Croatia.

Background: Possible new additives for surimi-like products made from chicken meat, which could improve its functional properties during frozen storage, are the subject of much research. The use of dietary fibre in surimi-like products made from chicken meat has not been extensively studied. The objective of this study was to determine the effectiveness of barley bran flour in stabilizing chicken myofibrillar proteins during frozen storage and maintaining its functionality. Read More

Cytotoxic activity of stigmasteryl esters and products of their thermo-oxidative degradation against drug sensitive and drug resistant human acute lymphoblastic leukemia cells.

Acta Sci Pol Technol Aliment 2018 Jan-Mar;17(1):11-18

Faculty of Food Science and Nutrition, Poznań University of Life Sciences, Poland.

Background: Phytosterols are mainly known as a cholesterol-lowering factor, although they form oxidation products during food storage and processing. Moreover, phytosterol oxidation products (POP) can be ab- sorbed and found in human serum, so there is the need to investigate their impact on different kinds of cells.

Methods: Esters of fatty acids (oleic, linoleic and linolenic) with stigmasterol were synthetized and heated at 180°C, for 1–12 hours. Read More
