Abstract
Fruits including berries are one of the most important sources of our daily nutrition due to their major aspect from point of view of consumers. The fruit quality includes the internal and external properties. The internal quality mainly is determined by aroma, flavor, taste, texture, nutritional quality (soluble sugar content, starch, organic acids, soluble solids content, and carotenoids, total flavonoids, total phenolic, antioxidant activity), flesh firmness, diseases, and chemical residues, while the external quality mainly concerns the appearance, size and colour and bruises. How to measure berry fruit quality has always been one of the most attractive research hotspots in the food industry. For the present, most of the available investigative methods are still destructive, labor and time-consuming; besides, several methods require sample preparation, costly instruments and chemicals, which cannot be used for large-scale sample evaluation. With the increasing demands of real-time detection of fruit quality, non-destructive fruit evaluation methods have been greatly developed. However, problems like low detection accuracy and poor model adaptability remain in the non-destructive detection system. Thus, it is necessary to develop non-destructive, high-efficient, simple, accurate and low-labor-cost techniques for fruit quality determination. In this paper, a comparison of different and advanced analytical methods for assessing the fruit quality characteristics of berries was discussed.
Highlights
IntroductionIt has been previously reported that dietary intervention with berry seed oils in the early stage of life may reduce the prevalence of atopic cardiovascular diseases, diabetes, obesity and cancer diseases [9] [10] [11] and [12]
Several chromatographic methods have been developed for identifying and quantifying individually organic acids in different matrixes. [19] used liquid chromatography coupled to tandem-mass spectrometry (LC–MS/MS) with triple quadrupole in selective reaction monitoring mode to determine organic acids in fruits including berries, . [20] identified and quantified organic acid content of several berries by high-performance liquid chromatography (HPLC) technique coupled with UV detector
Phenolic compounds might act as reducing substances, blocking free radicals, chelating metal ions, inhibitors of oxidation reaction, inhibitors of the activity of enzymes contributing to free radical creation
Summary
It has been previously reported that dietary intervention with berry seed oils in the early stage of life may reduce the prevalence of atopic cardiovascular diseases, diabetes, obesity and cancer diseases [9] [10] [11] and [12] Lifestyle factors, such as diet, obesity, and socioeconomic status, have a profound impact on cancer incidence. The World Health Organization (WHO) recommends a daily intake of more than 400 g of fruits and vegetables per person due to their importance in reducing many diseases [2] Due to their freshly consummated highly colored fruits, delicious taste, low calories and richness of their bioactive compounds, berry fruits have been constantly increasing in popularity over the last few decades. This paper will review the issues on detection of berry fruit quality parameters by advanced technologies that have been applied for measuring them
