Using Sensory Properties of Food to Trigger Swallowing: A Review

The effect of food consistency on swallowing function has been widely studied, and it is well recognized that by delaying the flow of the food bolus, thickened liquids can help in the management of swallowing dysfunction. However, fewer studies have been carried out on the impact of food sensory properties and related liking on swallowing function. This paper reviews the role of taste, olfaction, and trigeminal perceptions on swallowing function and highlights the need for a deeper investigation of this aspect of patient diet modification.     

四川绵竹灾区震后半个月的食品和饮用水卫生调查

目的为评估食品和饮用水防疫措施的落实情况,于震后半个月,对四川绵竹灾区的18个乡镇和2个城区安置点进行了调查。方法每个乡镇随机抽取2个村,每村随机抽取10户居民;2个城区安置点随机抽取20个帐篷,以调查问卷的形式对乡镇和安置点的基本情况、食品卫生情况和饮用水卫生情况进行调查。结果调查发现绝大多数乡镇受灾群众和全部城市安置点受灾群众能够得到安全的食品和饮用水,但在各乡镇中,仍有5.03%的受灾群众食用凉拌菜,12.85%吃过剩菜剩饭,还有不少群众饮用未消毒的井水(7/316)或河沟水(5/14)。结论本调查的结果表明早期的防疫措施的确起到了积极作用,但仍然存在一些问题,因此需要进一步提高灾后防病意识,加强与受灾群众生活息息相关的食品和饮用水卫生管理。

Benzyloxybenzaldehydethiosemicarbazone: Extractive Spectrophotometric Reagent for the Determination of Cu(II) in Food and Water Samples

Benzyloxybenzaldehydethiosemicarbazone (BBTSC) was prepared and developed a new method for the simple, highly selective, and extractive spectrophotometric determination of copper(II) with BBTSC at wavelength 370 nm. The metal ion formed a bluish green colored complex with BBTSC in acetate buffer of pH 5.0, which was easily extractable into n-butanol with 1:1(metal/ligand) composition. The method obeys Beer’s law in the range of 0.5–5.2 ppm. The molar absorptivity and Sandell’s sensitivity were found to be 1.5 × 10⁴ l mol⁻¹ cm⁻¹ and 0.00412 g cm⁻², respectively. The correlation coefficient of the Cu(II)–BBTSC complex was 0.998, which indicated an excellent linearity between the two variables. The repeatability of the method was checked by finding the relative standard deviation (RSD; n = 10), which was 0.377% and its detection limit 0.0204 μg ml⁻¹. The interfering effect of various cations and anions were also studied. The proposed method was successfully applied to the determination of copper(II) in food and water samples. Comparing the results with those obtained using an atomic absorption spectrophotometer tested the validity of the method.

National Food Control Systems: A Review

This article reviews literature on national food control systems (NFCS). The major objectives of NFCS, their main components, and current issues relating to NFCS are discussed. Common problem areas and the actions taken by countries to improve their system are analysed. The review shows that elements of NFCS suffer from certain limitations, such as obsolete food laws, duplication of work, lack of resources, and poor organisation, which make the system ineffective. NFCS have been established to various extents in both developed and developing countries; however, most countries have not used management techniques in developing and implementing their food control programme. Since NFCS face a number of challenges, it is important for both developed and developing countries to strengthen their food control systems to meet these challenges.
