Abstract

Purpose

The purpose of this paper is to explore the main Unmanned Aerial Vehicles (UAVs) projects proceeded by Turkey and to reveal the future targets and the status of Turkey among the countries securing enhanced UAV experience.

Design/methodology/approach

The historical development and the future of the UAV systems are analyzed by using the roadmaps, and reports about the UAV market.

Findings

It is found that the development and the production of indigineous UAV systems/subsystems will reduce the costs, and enable Turkey to be independent with respect to when, where, and how to use its own UAV systems.

Originality/value

This study provides historical context for recent developments in UAV sector in Turkey and presents some proposals for the future of the market.

Abstract

Purpose

Heterocyclic aromatic amines are mutagenic and/or carcinogenic compounds formed during cooking of meat. Therefore, the formation levels of them should be reduced. For this aim, the purpose of the present study was to determine the effect of dry breadcrumb in meatball production on the formation of heterocyclic aromatic amines. In addition, the effect of dry breadcrumb on some quality parameters of the meatballs was also investigated.

Design/methodology/approach

Meatball dough with 15 percent fat was divided into four parts, where one group was selected as the control group (without dry breadcrumb). In the other three groups, dry breadcrumb was added in various ratios of 5 percent, 10 percent and 15 percent (w/w). Then, meatball dough was stored at 4 °C for 3 h and shaped into meatballs with a metal shaping device (7 × 1 cm). For some of the quality parameters, water, pH, cooking loss and TBARS analyses were done in the samples. Heterocyclic aromatic amine analysis was done in only cooked samples according to solid phase extraction.

Findings

The use of dry breadcrumb in meatball production decreased water content and cooking loss. As cooking temperature increased, water contents and cooking loss of meatball decreased. PhIP, AαC and MeAαC were not detected in any of the samples analyzed. As cooking temperature increased, total amount of HCAs increased and ranged between 0.05 and 0.51 ng/g. While the use of dry breadcrumb in the meatball production increased IQ content of the meatballs, the use of 5 percent dry breadcrumb caused a decrease in the total HAA content (28.57–66.67 percent) for all cooking temperatures.

Originality/value

Many research studies including our study in the literature were conducted on formation and reduction of HAAs in meat and meat products. However, although dry breadcrumb is frequently used both in domestic and commercial meatball formulations; to the best of our knowledge, effect of using dry breadcrumb in meatball production on HAAs formation has not been investigated in the literature. Therefore, in the present study, the effects of the use of dry breadcrumb in meatball production on some quality parameters and formation of HAAs in meatballs cooked at 150 °C, 200 °C and 250 °C were determined.
