Abstract

Purpose

This study aims to evaluate the use of vacuum impregnation (VI) for developing vitamin E fortified fresh‐cut apples (Fuji).

Design/methodology/approach

A 20 per cent high fructose corn syrup (HFCS) or edible coating materials of 1 per cent hydroxypropyl methylcellulose (HPMC) and 1 per cent calcium caseinate (CC) were used to make VI solutions, and 0.4 per cent α‐tocopherol acetate, 7.5 per cent gluconal cal\tf="Pi3" \char"31 (GC) and 0.04 per cent zinc lactate (ZL) were incorporated into the VI solutions. Vitamin E content, color, and selected physicochemical properties of fortified fresh‐cut apples were analyzed.

Findings

Results showed that VI treatment with 20 per cent HFCS solution containing 0.4 per cent α‐tocopherol acetate increased vitamin E content up to 21.8 mg in 100 g of fresh‐cut apples, while 12.0 mg and 20.2 mg vitamin E were achieved when using 1 per cent HPMC or 1 per cent CC as VI solutions, respectively. Calcium and zinc content were also increased to 146.6 mg and 1.7 mg in 100 g of apples, respectively, when adding 7.5 per cent GC and 0.04 per cent ZL along with the vitamin E into the VI solutions. Use of HFCS, HPMC and CC as VI solutions resulted in different effects on the physiochemical properties of fresh‐cut apples. While HFCS is promising for vitamin E fortification and retention of natural apple color, HPMC and CC can be used to achieve similar vitamin E fortification with the least impact on the soluble solids and moisture contents of apples.

Originality/value

The study demonstrates that there is great potential for developing high quality, vitamin E and minerals fortified fresh‐cut apples using vacuum impregnation technology, thus further enhancing the health benefit of the apples.

Abstract

Purpose

The purpose of this paper is to test the relationship between innovation performance and innovation spillover effects, innovation inputs, innovation outputs and industrial effects.

Design/methodology/approach

The analysis framework including variables such as innovation spillover effect, innovation input, innovation output and industrial effect was constructed. Through the investigation and analysis of the innovation activities of China’s GEM listed companies in 2014–2016, the innovation performance and the above factors were tested.

Findings

The research shows that enterprise performance has a significant positive correlation with innovation input and innovation output, but there is no significant correlation or even negative correlation with innovation environment and industry background such as government support and innovation opportunities, and the spillover effect is significant. The negative correlation is also negatively correlated with innovative human capital investment, company age and company Q.

Originality/value

Innovation is the real source of economic growth, and industrial innovation is the system integration of technological innovation, product innovation, market innovation, etc., which is the basic determinant of national competitiveness.
