Effect of Various Types of Heat Processing on the Content and Retention of Fat-Soluble Vitamins and Cholesterol in Goose Breast Meat.

Abstract

Background/objectives: Heat processing techniques can alter the energy and nutritional value of meat. This study examined the effect of various types of heat processing (water bath cooking WBC, oven convection roasting OCR, grilling G, and pan frying PF) on the content and retention of vitamins A, D, E, K, and cholesterol in White Kołuda^® goose breast meat without or with skin (n = 36).

Methods: The contents of fat-soluble vitamins and cholesterol were determined by High-Performance Liquid Chromatography (HPLC). Cooking loss (CL), retention, and the percentage coverage of the Nutrient Reference Values (NRV) for vitamins in adults by 100 g of meat were calculated.

Results: The CL was higher (p ≤ 0.01) in goose breast meat with skin (43.2%) compared to skinless meat (37.1%). The contents of vitamins A, D, E, K, and cholesterol were also significantly greater (p ≤ 0.01) in meat with skin than in meat without skin. The G and PF resulted in the greatest reductions in A, D, E, and K compared with raw meat. The highest retention (>52%) was observed after WBC, whereas the lowest (<43.7%) occurred after PF, although the difference was statistically significant (p ≤ 0.01) only for vitamin D. While 100 g of raw goose breast meat provided the highest percentage of NRV for the analyzed components, WBC appeared to be the most favorable cooking method for consumers.

Conclusions: Our research can help consumers choose goose meat as an alternative to red meat to diversify and balance their diet. WBC ensures the least loss of fat-soluble vitamins while ensuring the health safety of meat, which may be important information for consumers, the catering industry, and the poultry industry.
